42 | |||
43 | 1. NOTE | ||
44 | This software has been successfully in alpha and beta test and is part of | ||
45 | the standard kernel since kernel 1.1.8x since December 1994. It works with | ||
46 | AZTECH CDA268-01A, ORCHID CDS-3110, ORCHID/WEARNES CDD110 and CONRAD TXC | ||
47 | (Nr.99 31 23 -series 04) and has proven to be stable with kernel | ||
48 | versions 1.0.9 and newer. But with any software there still may be bugs in it. | ||
49 | So if you encounter problems, you are invited to help us improve this software. | ||
50 | Please send me a detailed bug report (see chapter BUG REPORTS). You are also | ||
51 | invited in helping us to increase the number of drives, which are supported. | ||
52 | |||
53 | Please read the README-files carefully and always keep a backup copy of your | ||
54 | old kernel, in order to reboot if something goes wrong! | ||
55 | |||
56 | 2. INSTALLATION | ||
57 | The driver consists of a header file 'aztcd.h', which normally should reside | ||
58 | in /usr/src/linux/drivers/cdrom and the source code 'aztcd.c', which normally | ||
59 | resides in the same place. It uses /dev/aztcd (/dev/aztcd0 in some distri- | ||
60 | butions), which must be a valid block device with major number 29 and reside | ||
61 | in directory /dev. To mount a CD-ROM, your kernel needs to have the ISO9660- | ||
62 | filesystem support included. | ||
63 | |||
64 | PLEASE NOTE: aztcd.c has been developed in parallel to the linux kernel, | ||
65 | which had and is having many major and minor changes which are not backward | ||
66 | compatible. Quite definitely aztcd.c version 1.80 and newer will NOT work | ||
67 | in kernels older than 1.3.33. So please always use the most recent version | ||
68 | of aztcd.c with the appropriate linux-kernel. | ||
69 | |||
70 | 3. CONFIGURING YOUR KERNEL | ||
71 | If your kernel is already configured for using the AZTECH driver you will | ||
72 | see the following message while Linux boots: | ||
73 | Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress> | ||
74 | Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card>>> | ||
75 | Aztech CD-ROM Init: <drive type> detected | ||
76 | Aztech CD-ROM Init: End | ||
77 | If the message looks different and you are sure to have a supported drive, | ||
78 | it may have a different base address. The Aztech driver does look for the | ||
79 | CD-ROM drive at the base address specified in aztcd.h at compile time. This | ||
80 | address can be overwritten by boot parameter aztcd=....You should reboot and | ||
81 | start Linux with boot parameter aztcd=<base address>, e.g. aztcd=0x320. If | ||
82 | you do not know the base address, start your PC with DOS and look at the boot | ||
83 | message of your CD-ROM's DOS driver. If that still does not help, use boot | ||
84 | parameter aztcd=<base address>,0x79 , this tells aztcd to try a little harder. | ||
85 | aztcd may be configured to use autoprobing the base address by recompiling | ||
86 | it (see chapter 4.). | ||
87 | |||
88 | If the message looks correct, as user 'root' you should be able to mount the | ||
89 | drive by | ||
90 | mount -t iso9660 -r /dev/aztcd0 /mnt | ||
91 | and use it as any other filesystem. (If this does not work, check if | ||
92 | /dev/aztcd0 and /mnt do exist and create them, if necessary by doing | ||
93 | mknod /dev/aztcd0 b 29 0 | ||
94 | mkdir /mnt | ||
95 | |||
96 | If you still get a different message while Linux boots or when you get the | ||
97 | message, that the ISO9660-filesystem is not supported by your kernel, when | ||
98 | you try to mount the CD-ROM drive, you have to recompile your kernel. | ||
99 | |||
100 | If you do *not* have an Aztech/Orchid/Okano/Wearnes/TXC drive and want to | ||
101 | bypass drive detection during Linux boot up, start with boot parameter aztcd=0. | ||
102 | |||
103 | Most distributions nowadays do contain a boot disk image containing aztcd. | ||
104 | Please note, that this driver will not work with IDE/ATAPI drives! With these | ||
105 | you must use ide-cd.c instead. | ||
106 | |||
107 | 4. RECOMPILING YOUR KERNEL | ||
108 | If your kernel is not yet configured for the AZTECH driver and the ISO9660- | ||
109 | filesystem, you have to recompile your kernel: | ||
110 | |||
111 | - Edit aztcd.h to set the I/O-address to your I/O-Base address (AZT_BASE_ADDR), | ||
112 | the driver does not use interrupts or DMA, so if you are using an AZTECH | ||
113 | CD268, an ORCHID CD-3110 or ORCHID/WEARNES CDD110 that's the only item you | ||
114 | have to set up. If you have a soundcard, read chapter 4.2. | ||
115 | Users of other drives should read chapter OTHER DRIVES of this file. | ||
116 | You also can configure that address by kernel boot parameter aztcd=... | ||
117 | - aztcd may be configured to use autoprobing the base address by setting | ||
118 | AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed | ||
119 | under AZT_BASE_AUTO. But please remember, that autoprobing always may | ||
120 | incorrectly influence other hardware components too! | ||
121 | - There are some other points, which may be configured, e.g. auto-eject the | ||
122 | CD when unmounting a drive, tray locking etc., see aztcd.h for details. | ||
123 | - If you're using a linux kernel version prior to 2.1.0, in aztcd.h | ||
124 | uncomment the line '#define AZT_KERNEL_PRIOR_2_1' | ||
125 | - Build a new kernel, configure it for 'Aztech/Orchid/Okano/Wearnes support' | ||
126 | (if you want aztcd to be part of the kernel). Do not configure it for | ||
127 | 'Aztech... support', if you want to use aztcd as a run time loadable module. | ||
128 | But in any case you must have the ISO9660-filesystem included in your | ||
129 | kernel. | ||
130 | - Activate the new kernel, normally this is done by running LILO (don't for- | ||
131 | get to configure it before and to keep a copy of your old kernel in case | ||
132 | something goes wrong!). | ||
133 | - Reboot | ||
134 | - If you've included aztcd in your kernel, you now should see during boot | ||
135 | some messages like | ||
136 | Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress> | ||
137 | Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card> | ||
138 | Aztech CD-ROM Init: <drive type> detected | ||
139 | Aztech CD-ROM Init: End | ||
140 | - If you have not included aztcd in your kernel, but want to load aztcd as a | ||
141 | run time loadable module see 4.1. | ||
142 | - If the message looks correct, as user 'root' you should be able to mount | ||
143 | the drive by | ||
144 | mount -t iso9660 -r /dev/aztcd0 /mnt | ||
145 | and use it as any other filesystem. (If this does not work, check if | ||
146 | /dev/aztcd0 and /mnt do exist and create them, if necessary by doing | ||
147 | mknod /dev/aztcd0 b 29 0 | ||
148 | mkdir /mnt | ||
149 | - If this still does not help, see chapters OTHER DRIVES and DEBUGGING. | ||
150 | |||
151 | 4.1 AZTCD AS A RUN-TIME LOADABLE MODULE | ||
152 | If you do not need aztcd permanently, you can also load and remove the driver | ||
153 | during runtime via insmod and rmmod. To build aztcd as a loadable module you | ||
154 | must configure your kernel for AZTECH module support (answer 'm' when con- | ||
155 | figuring the kernel). Anyhow, you may run into problems, if the version of | ||
156 | your boot kernel is not the same than the source kernel version, from which | ||
157 | you create the modules. So rebuild your kernel, if necessary. | ||
158 | |||
159 | Now edit the base address of your AZTECH interface card in | ||
160 | /usr/src/linux/drivers/cdrom/aztcd.h to the appropriate value. | ||
161 | aztcd may be configured to use autoprobing the base address by setting | ||
162 | AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed | ||
163 | under AZT_BASE_AUTO. But please remember, that autoprobing always may | ||
164 | incorrectly influence other hardware components too! | ||
165 | There are also some special features which may be configured, e.g. | ||
166 | auto-eject a CD when unmounting the drive etc; see aztcd.h for details. | ||
167 | Then change to /usr/src/linux and do a | ||
168 | make modules | ||
169 | make modules_install | ||
170 | After that you can run-time load the driver via | ||
171 | insmod /lib/modules/X.X.X/misc/aztcd.o | ||
172 | and remove it via rmmod aztcd. | ||
173 | If you did not set the correct base address in aztcd.h, you can also supply the | ||
174 | base address when loading the driver via | ||
175 | insmod /lib/modules/X.X.X/misc/aztcd.o aztcd=<base address> | ||
176 | Again specifying aztcd=-1 will cause autoprobing. | ||
177 | If you do not have the iso9660-filesystem in your boot kernel, you also have | ||
178 | to load it before you can mount the CDROM: | ||
179 | insmod /lib/modules/X.X.X/fs/isofs.o | ||
180 | The mount procedure works as described in 4. above. | ||
181 | (In all commands 'X.X.X' is the current linux kernel version number) | ||
182 | |||
183 | 4.2 CDROM CONNECTED TO A SOUNDCARD | ||
184 | Most soundcards do have a bus interface to the CDROM-drive. In many cases | ||
185 | this soundcard needs to be configured, before the CDROM can be used. This | ||
186 | configuration procedure consists of writing some kind of initialization | ||
187 | data to the soundcard registers. The AZTECH-CDROM driver in the moment does | ||
188 | only support one type of soundcard (SoundWave32). Users of other soundcards | ||
189 | should try to boot DOS first and let their DOS drivers initialize the | ||
190 | soundcard and CDROM, then warm boot (or use loadlin) their PC to start | ||
191 | Linux. | ||
192 | Support for the CDROM-interface of SoundWave32-soundcards is directly | ||
193 | implemented in the AZTECH driver. Please edit linux/drivers/cdrom/aztdc.h, | ||
194 | uncomment line '#define AZT_SW32' and set the appropriate value for | ||
195 | AZT_BASE_ADDR and AZT_SW32_BASE_ADDR. This support was tested with an Orchid | ||
196 | CDS-3110 connected to a SoundWave32. | ||
197 | If you want your soundcard to be supported, find out, how it needs to be | ||
198 | configured and mail me (see 6.) the appropriate information. | ||
199 | |||
200 | 5. KNOWN PROBLEMS, FUTURE DEVELOPMENTS | ||
201 | 5.1 MULTISESSION SUPPORT | ||
202 | Multisession support for CD's still is a myth. I implemented and tested a basic | ||
203 | support for multisession and XA CDs, but I still have not enough CDs and appli- | ||
204 | cations to test it rigorously. So if you'd like to help me, please contact me | ||
205 | (Email address see below). As of version 1.4 and newer you can enable the | ||
206 | multisession support in aztcd.h by setting AZT_MULTISESSION to 1. Doing so | ||
207 | will cause the ISO9660-filesystem to deal with multisession CDs, ie. redirect | ||
208 | requests to the Table of Contents (TOC) information from the last session, | ||
209 | which contains the info of all previous sessions etc.. If you do set | ||
210 | AZT_MULTISESSION to 0, you can use multisession CDs anyway. In that case the | ||
211 | drive's firmware will do automatic redirection. For the ISO9660-filesystem any | ||
212 | multisession CD will then look like a 'normal' single session CD. But never- | ||
213 | theless the data of all sessions are viewable and accessible. So with practical- | ||
214 | ly all real world applications you won't notice the difference. But as future | ||
215 | applications may make use of advanced multisession features, I've started to | ||
216 | implement the interface for the ISO9660 multisession interface via ioctl | ||
217 | CDROMMULTISESSION. | ||
218 | |||
219 | 5.2 STATUS RECOGNITION | ||
220 | The drive status recognition does not work correctly in all cases. Changing | ||
221 | a disk or having the door open, when a drive is already mounted, is detected | ||
222 | by the Aztech driver itself, but nevertheless causes multiple read attempts | ||
223 | by the different layers of the ISO9660-filesystem driver, which finally timeout, | ||
224 | so you have to wait quite a little... But isn't it bad style to change a disk | ||
225 | in a mounted drive, anyhow ?! | ||
226 | |||
227 | The driver uses busy wait in most cases for the drive handshake (macros | ||
228 | STEN_LOW and DTEN_LOW). I tested with a 486/DX2 at 66MHz and a Pentium at | ||
229 | 60MHz and 90MHz. Whenever you use a much faster machine you are likely to get | ||
230 | timeout messages. In that case edit aztcd.h and increase the timeout value | ||
231 | AZT_TIMEOUT. | ||
232 | |||
233 | For some 'slow' drive commands I implemented waiting with a timer waitqueue | ||
234 | (macro STEN_LOW_WAIT). If you get this timeout message, you may also edit | ||
235 | aztcd.h and increase the timeout value AZT_STATUS_DELAY. The waitqueue has | ||
236 | shown to be a little critical. If you get kernel panic messages, edit aztcd.c | ||
237 | and substitute STEN_LOW_WAIT by STEN_LOW. Busy waiting with STEN_LOW is more | ||
238 | stable, but also causes CPU overhead. | ||
239 | |||
240 | 5.3 DOSEMU's CD-ROM SUPPORT | ||
241 | With release 1.20 aztcd was modified to allow access to CD-ROMS when running | ||
242 | under dosemu-0.60.0 aztcd-versions before 1.20 are most likely to crash | ||
243 | Linux, when a CD-ROM is accessed under dosemu. This problem has partly been | ||
244 | fixed, but still when accessing a directory for the first time the system | ||
245 | might hang for some 30sec. So be patient, when using dosemu's CD-ROM support | ||
246 | in combination with aztcd :-) ! | ||
247 | This problem has now (July 1995) been fixed by a modification to dosemu's | ||
248 | CD-ROM driver. The new version came with dosemu-0.60.2, see dosemu's | ||
249 | README.CDROM. | ||
250 | |||
251 | 6. BUG REPORTS | ||
252 | Please send detailed bug reports and bug fixes via EMail to | ||
253 | |||
254 | Werner.Zimmermann@fht-esslingen.de | ||
255 | |||
256 | Please include a description of your CD-ROM drive type and interface card, | ||
257 | the exact firmware message during Linux bootup, the version number of the | ||
258 | AZTECH-CDROM-driver and the Linux kernel version. Also a description of your | ||
259 | system's other hardware could be of interest, especially microprocessor type, | ||
260 | clock frequency, other interface cards such as soundcards, ethernet adapter, | ||
261 | game cards etc.. | ||
262 | |||
263 | I will try to collect the reports and make the necessary modifications from | ||
264 | time to time. I may also come back to you directly with some bug fixes and | ||
265 | ask you to do further testing and debugging. | ||
266 | |||
267 | Editors of CD-ROMs are invited to send a 'cooperation' copy of their | ||
268 | CD-ROMs to the volunteers, who provided the CD-ROM support for Linux. My | ||
269 | snail mail address for such 'stuff' is | ||

278 | 7. OTHER DRIVES | ||
279 | The following drives ORCHID CDS3110, OKANO CDD110, WEARNES CDD110 and Conrad | ||
280 | TXC Nr. 993123-series 04 nearly look the same as AZTECH CDA268-01A, especially | ||
281 | they seem to use the same command codes. So it was quite simple to make the | ||
282 | AZTECH driver work with these drives. | ||
283 | |||
284 | Unfortunately I do not have any of these drives available, so I couldn't test | ||
285 | it myself. In some installations, it seems necessary to initialize the drive | ||
286 | with the DOS driver before (especially if combined with a sound card) and then | ||
287 | do a warm boot (CTRL-ALT-RESET) or start Linux from DOS, e.g. with 'loadlin'. | ||
288 | |||
289 | If you do not succeed, read chapter DEBUGGING. Thanks in advance! | ||
290 | |||
291 | Sorry for the inconvenience, but it is difficult to develop for hardware, | ||
292 | which you don't have available for testing. So if you like, please help us. | ||
293 | |||
294 | If you do have a CyCDROM CR520ie thanks to Hilmar Berger's help your chances | ||
295 | are good, that it will work with aztcd. The CR520ie is sold as an IDE-drive | ||
296 | and really is connected to the IDE interface (primary at 0x1F0 or secondary | ||
297 | at 0x170, configured as slave, not as master). Nevertheless it is not ATAPI | ||
298 | compatible but still uses Aztech's command codes. | ||
299 | |||
300 | |||
301 | 8. DEBUGGING : IF YOU DON'T SUCCEED, TRY THE FOLLOWING | ||
302 | -reread the complete README file | ||
303 | -make sure, that your drive is hardware configured for | ||
304 | transfer mode: polled | ||
305 | IRQ: not used | ||
306 | DMA: not used | ||
307 | Base Address: something like 300, 320 ... | ||
308 | You can check this, when you start the DOS driver, which came with your | ||
309 | drive. By appropriately configuring the drive and the DOS driver you can | ||
310 | check, whether your drive does operate in this mode correctly under DOS. If | ||
311 | it does not operate under DOS, it won't under Linux. | ||
312 | If your drive's base address is something like 0x170 or 0x1F0 (and it is | ||
313 | not a CyCDROM CR520ie or CR 940ie) you most likely are having an IDE/ATAPI- | ||
314 | compatible drive, which is not supported by aztcd.c, use ide-cd.c instead. | ||
315 | Make sure the Base Address is configured correctly in aztcd.h, also make | ||
316 | sure, that /dev/aztcd0 exists with the correct major number (compare it with | ||
317 | the entry in file /usr/include/linux/major.h for the Aztech drive). | ||
318 | -insert a CD-ROM and close the tray | ||
319 | -cold boot your PC (i.e. via the power on switch or the reset button) | ||
320 | -if you start Linux via DOS, e.g. using loadlin, make sure, that the DOS | ||
321 | driver for the CD-ROM drive is not loaded (comment out the calling lines | ||
322 | in DOS' config.sys!) | ||
323 | -look for the aztcd: init message during Linux init and note them exactly | ||
324 | -log in as root and do a mount -t iso9660 /dev/aztcd0 /mnt | ||
325 | -if you don't succeed in the first time, try several times. Try also to open | ||
326 | and close the tray, then mount again. Please note carefully all commands | ||
327 | you typed in and the aztcd-messages, which you get. | ||
328 | -if you get an 'Aztech CD-ROM init: aborted' message, read the remarks about | ||
329 | the version string below. | ||
330 | |||
331 | If this does not help, do the same with the following differences | ||
332 | -start DOS before; make now sure, that the DOS driver for the CD-ROM is | ||
333 | loaded under DOS (i.e. uncomment it again in config.sys) | ||
334 | -warm boot your PC (i.e. via CTRL-ALT-DEL) | ||
335 | if you have it, you can also start via loadlin (try both). | ||
336 | ... | ||
337 | Again note all commands and the aztcd-messages. | ||
338 | |||
339 | If you see STEN_LOW or STEN_LOW_WAIT error messages, increase the timeout | ||
340 | values. | ||
341 | |||
342 | If this still does not help, | ||
343 | -look in aztcd.c for the lines #if 0 | ||
344 | #define AZT_TEST1 | ||
345 | ... | ||
346 | #endif | ||
347 | and substitute '#if 0' by '#if 1'. | ||
348 | -recompile your kernel and repeat the above two procedures. You will now get | ||
349 | a bundle of debugging messages from the driver. Again note your commands | ||
350 | and the appropriate messages. If you have syslogd running, these messages | ||
351 | may also be found in syslogd's kernel log file. Nevertheless in some | ||
352 | installations syslogd does not yet run, when init() is called, thus look for | ||
353 | the aztcd-messages during init, before the login-prompt appears. | ||
354 | Then look in aztcd.c, to find out, what happened. The normal calling sequence | ||
355 | is: aztcd_init() during Linux bootup procedure init() | ||
356 | after doing a 'mount -t iso9660 /dev/aztcd0 /mnt' the normal calling sequence is | ||
357 | aztcd_open() -> Status 2c after cold reboot with CDROM or audio CD inserted | ||
358 | -> Status 8 after warm reboot with CDROM inserted | ||
359 | -> Status 2e after cold reboot with no disk, closed tray | ||
360 | -> Status 6e after cold reboot, mount with door open | ||
361 | aztUpdateToc() | ||
362 | aztGetDiskInfo() | ||
363 | aztGetQChannelInfo() repeated several times | ||
364 | aztGetToc() | ||
365 | aztGetQChannelInfo() repeated several times | ||
366 | a list of track information | ||
367 | do_aztcd_request() } | ||
368 | azt_transfer() } repeated several times | ||
369 | azt_poll } | ||
370 | Check, if there is a difference in the calling sequence or the status flags! | ||
371 | |||
372 | There are a lot of other messages, eg. the ACMD-command code (defined in | ||
373 | aztcd.h), status info from the getAztStatus-command and the state sequence of | ||
374 | the finite state machine in azt_poll(). The most important are the status | ||
375 | messages, look how they are defined and try to understand, if they make | ||
376 | sense in the context where they appear. With a CD-ROM inserted the status | ||
377 | should always be 8, except in aztcd_open(). Try to open the tray, insert an | ||
378 | audio disk, insert no disk or reinsert the CD-ROM and check, if the status | ||
379 | bits change accordingly. The status bits are the most likely point, where | ||
380 | the drive manufacturers may implement changes. | ||
381 | |||
382 | If you still don't succeed, a good point to start is to look in aztcd.c in | ||
383 | function aztcd_init, where the drive should be detected during init. Do the | ||
384 | following: | ||
385 | -reboot the system with boot parameter 'aztcd=<your base address>,0x79'. With | ||
386 | parameter 0x79 most of the drive version detection is bypassed. After that | ||
387 | you should see the complete version string including leading and trailing | ||
388 | blanks during init. | ||
389 | Now adapt the statement | ||
390 | if ((result[1]=='A')&&(result[2]=='Z' ...) | ||
391 | in aztcd_init() to exactly match the first 3 or 4 letters you have seen. | ||
392 | -Another point is the 'smart' card detection feature in aztcd_init(). Normally | ||
393 | the CD-ROM drive is ready, when aztcd_init is trying to read the version | ||
394 | string and a time consuming ACMD_SOFT_RESET command can be avoided. This is | ||
395 | detected by looking, if AFL_OP_OK can be read correctly. If the CD-ROM drive | ||
396 | hangs in some unknown state, e.g. because of an error before a warm start or | ||
397 | because you first operated under DOS, even the version string may be correct, | ||
398 | but the following commands will not. Then change the code in such a way, | ||
399 | that the ACMD_SOFT_RESET is issued in any case, by substituting the | ||
400 | if-statement 'if ( ...=AFL_OP_OK)' by 'if (1)'. | ||
401 | |||
402 | If you succeed, please mail me the exact version string of your drive and | ||
403 | the code modifications, you have made together with a short explanation. | ||
404 | If you don't succeed, you may mail me the output of the debugging messages. | ||
405 | But remember, they are only useful, if they are exact and complete and you | ||
406 | describe in detail your hardware setup and what you did (cold/warm reboot, | ||
407 | with/without DOS, DOS-driver started/not started, which Linux-commands etc.) | ||
408 | |||
409 | |||
410 | 9. TECHNICAL HISTORY OF THE DRIVER | ||
411 | The AZTECH-Driver is a rework of the Mitsumi-Driver. Four major items had to | ||
412 | be reworked: | ||
413 | |||
414 | a) The Mitsumi drive does issue complete status information acknowledging | ||
415 | each command, the Aztech drive does only signal that the command was | ||
416 | processed. So whenever the complete status information is needed, an extra | ||
417 | ACMD_GET_STATUS command is issued. The handshake procedure for the drive | ||
418 | can be found in the functions aztSendCmd(), sendAztCmd() and getAztStatus(). | ||
419 | |||
420 | b) The Aztech Drive does not have a ACMD_GET_DISK_INFO command, so the | ||
421 | necessary info about the number of tracks (firstTrack, lastTrack), disk | ||
422 | length etc. has to be read from the TOC in the lead in track (see function | ||
423 | aztGetDiskInfo()). | ||
424 | |||
425 | c) Whenever data is read from the drive, the Mitsumi drive is started with a | ||
426 | command to read an indefinite (0xffffff) number of sectors. When the appropriate | ||
427 | number of sectors is read, the drive is stopped by a ACDM_STOP command. This | ||
428 | does not work with the Aztech drive. I did not find a way to stop it. The | ||
429 | stop and pause commands do only work in AUDIO mode but not in DATA mode. | ||
430 | Therefore I had to modify the 'finite state machine' in function azt_poll to | ||
431 | only read a certain number of sectors and then start a new read on demand. As I | ||
432 | have not completely understood, how the buffer/caching scheme of the Mitsumi | ||
433 | driver was implemented, I am not sure, if I have covered all cases correctly, | ||
434 | whenever you get timeout messages, the bug is most likely to be in that | ||
435 | function azt_poll() around switch(cmd) .... case ACD_S_DATA. | ||
436 | |||
437 | d) I did not get information about changing drive mode. So I doubt, that the | ||
438 | code around function azt_poll() case AZT_S_MODE does work. In my test I have | ||
439 | not been able to switch to reading in raw mode. For reading raw mode, Aztech | ||
440 | uses a different command than for cooked mode, which I only have implemen- | ||
441 | ted in the ioctl-section but not in the section which is used by the ISO9660. | ||
442 | |||
443 | The driver was developed on an AST PC with Intel 486/DX2, 8MB RAM, 340MB IDE | ||
444 | hard disk and on an AST PC with Intel Pentium 60MHz, 16MB RAM, 520MB IDE | ||
445 | running Linux kernel version 1.0.9 from the LST 1.8 Distribution. The kernel | ||
446 | was compiled with gcc.2.5.8. My CD-ROM drive is an Aztech CDA268-01A. My | ||
447 | drive says, that it has Firmware Version AZT26801A1.3. It came with an ISA-bus | ||
448 | interface card and works with polled I/O without DMA and without interrupts. | ||
449 | The code for all other drives was 'remote' tested and debugged by a number of | ||
450 | volunteers on the Internet. | ||
451 | |||
452 | Points, where I feel that possible problems might be and all points where I | ||
453 | did not completely understand the drive's behaviour or trust my own code are | ||
454 | marked with /*???*/ in the source code. There are also some parts in the | ||
455 | Mitsumi driver, where I did not completely understand their code. | ||
456 | |||
457 | |||
458 | 10. ACKNOWLEDGMENTS | ||
459 | Without the help of P.Bush, Aztech, who delivered technical information | ||
460 | about the Aztech Drive and without the help of E.Moenkeberg, GWDG, who did a | ||
461 | great job in analyzing the command structure of various CD-ROM drives, this | ||
462 | work would not have been possible. E.Moenkeberg was also a great help in | ||
463 | making the software 'kernel ready' and in answering many of the CDROM-related | ||
464 | questions in the newsgroups. He really is *the* Linux CD-ROM guru. Thanks | ||
465 | also to all the guys on the Internet, who collected valuable technical | ||
466 | information about CDROMs. | ||
467 | |||
468 | Joe Nardone (joe@access.digex.net) was a patient tester even for my first | ||
469 | trial, which was more than slow, and made suggestions for code improvement. | ||
470 | Especially the 'finite state machine' azt_poll() was rewritten by Joe to get | ||
471 | clean C code and avoid the ugly 'gotos', which I copied from mcd.c. | ||
472 | |||
473 | Robby Schirmer (schirmer@fmi.uni-passau.de) tested the audio stuff (ioctls) | ||
474 | and suggested a lot of patches for them. | ||
475 | |||
476 | Joseph Piskor and Peter Nugent were the first users with the ORCHID CD3110 | ||
477 | and also were very patient with the problems which occurred. | ||
478 | |||
479 | Reinhard Max delivered the information for the CDROM-interface of the | ||
480 | SoundWave32 soundcards. | ||
481 | |||
482 | Jochen Kunz and Olaf Kaluza delivered the information for supporting Conrad's | ||
483 | TXC drive. | ||
484 | |||
485 | Hilmar Berger delivered the patches for supporting CyCDROM CR520ie. | ||
486 | |||
487 | Anybody, who is interested in these items should have a look at 'ftp.gwdg.de', | ||
488 | directory 'pub/linux/cdrom' and at 'ftp.cdrom.com', directory 'pub/cdrom'. | ||
489 | |||
490 | 11. PROGRAMMING ADD ONs: cdplay.c | ||
491 | You can use the ioctl-functions included in aztcd.c in your own programs. As | ||
492 | an example on how to do this, you will find a tiny CD Player for audio CDs | ||
493 | named 'cdplay.c'. It allows you to play audio CDs. You can play a specified | ||
494 | track, pause and resume or skip tracks forward and backwards. If you quit the | ||
495 | program without stopping the drive, playing is continued. You can also | ||
496 | (mis)use cdplay to read and hexdump data disks. You can find the code in the | ||
497 | APPENDIX of this file, which you should cut out with an editor and store in a | ||
498 | separate file 'cdplay.c'. To compile it and make it executable, do | ||
499 | gcc -s -Wall -O2 -L/usr/lib cdplay.c -o /usr/local/bin/cdplay # compiles it | ||
500 | chmod +755 /usr/local/bin/cdplay # makes it executable | ||
501 | ln -s /dev/aztcd0 /dev/cdrom # creates a link | ||
502 | (for /usr/lib substitute the top level directory, where your include files | ||
503 | reside, and for /usr/local/bin the directory, where you want the executable | ||
504 | binary to reside ) | ||
505 | |||
506 | You have to set the correct permissions for cdplay *and* for /dev/mcd0 or | ||
507 | /dev/aztcd0 in order to use it. Remember, that you should not have /dev/cdrom | ||
508 | mounted, when you're playing audio CDs. | ||
509 | |||
510 | This program is just a hack for testing the ioctl-functions in aztcd.c. I will | ||
511 | not maintain it, so if you run into problems, discard it or have a look into | ||
512 | the source code 'cdplay.c'. The program does only contain a minimum of user | ||
513 | protection and input error detection. If you use the commands in the wrong | ||
514 | order or if you try to read a CD at wrong addresses, you may get error messages | ||
515 | or even hang your machine. If you get STEN_LOW, STEN_LOW_WAIT or segment violation | ||
516 | error messages when using cdplay, after that, the system might not be stable | ||
517 | any more, so you'd better reboot. As the ioctl-functions run in kernel mode, | ||
518 | most normal Linux-multitasking protection features do not work. By using | ||
519 | uninitialized 'wild' pointers etc., it is easy to write to other users' data | ||
520 | and program areas, destroy kernel tables etc.. So if you experiment with ioctls | ||
521 | as always when you are doing systems programming and kernel hacking, you | ||
522 | should have a backup copy of your system in a safe place (and you also | ||
523 | should try restoring from a backup copy first)! | ||
524 | |||
525 | A reworked and improved version called 'cdtester.c', which has yet more | ||
526 | features for testing CDROM-drives can be found in | ||
527 | Documentation/cdrom/sbpcd, written by E.Moenkeberg. | ||

17 | Configuring as a Module | ||
18 | Driver Special Features | ||
19 | |||
20 | |||
21 | This device driver handles Sony CDU31A/CDU33A CDROM drives and | ||
22 | provides a complete block-level interface as well as an ioctl() | ||
23 | interface as specified in include/linux/cdrom.h). With this | ||
24 | interface, CDROMs can be accessed, standard audio CDs can be played | ||
25 | back normally, and CD audio information can be read off the drive. | ||
26 | |||
27 | Note that this will only work for CDU31A/CDU33A drives. Some vendors | ||
28 | market their drives as CDU31A compatible. They lie. Their drives are | ||
29 | really CDU31A hardware interface compatible (they can plug into the | ||
30 | same card). They are not software compatible. | ||
31 | |||
32 | Setting Up the Hardware | ||
33 | ----------------------- | ||
34 | |||
35 | The CDU31A driver is unable to safely tell if an interface card is | ||
36 | present that it can use because the interface card does not announce | ||
37 | its presence in any way besides placing 4 I/O locations in memory. It | ||
38 | used to just probe memory and attempt commands, but Linus wisely asked | ||
39 | me to remove that because it could really screw up other hardware in | ||
40 | the system. | ||
41 | |||
42 | Because of this, you must tell the kernel where the drive interface | ||
43 | is, what interrupts are used, and possibly if you are on a PAS-16 | ||
44 | soundcard. | ||
45 | |||
46 | If you have the Sony CDU31A/CDU33A drive interface card, the following | ||
47 | diagram will help you set it up. If you have another card, you are on | ||
48 | your own. You need to make sure that the I/O address and interrupt is | ||
49 | not used by another card in the system. You will need to know the I/O | ||
50 | address and interrupt you have set. Note that use of interrupts is | ||
51 | highly recommended, if possible, it really cuts down on CPU used. | ||
52 | Unfortunately, most soundcards do not support interrupts for their | ||
53 | CDROM interfaces. By default, the Sony interface card comes with | ||
54 | interrupts disabled. | ||

74 | |||
75 | Address Pin 1 Pin 2 | ||
76 | ------- ----- ----- | ||
77 | 0x320 Short Short | ||
78 | 0x330 Short Open | ||
79 | 0x340 Open Short | ||
80 | 0x360 Open Open | ||
81 | |||
82 | JP2 and JP3 configure the DMA channel; they must be set the same. | ||
83 | |||

94 | 3 Off Off On Off | ||
95 | 4 Off Off* Off On | ||
96 | 5 On Off Off Off | ||
97 | 6 Off On Off Off | ||
98 | |||
99 | The documentation states to set this for interrupt | ||
100 | 4, but I think that is a mistake. | ||
101 | |||
102 | Note that if you have another interface card, you will need to look at | ||
103 | the documentation to find the I/O base address. This is specified to | ||
104 | the SLCD.SYS driver for DOS with the /B: parameter, so you can look at | ||
105 | you DOS driver setup to find the address, if necessary. | ||
106 | |||
107 | Configuring the Kernel | ||
108 | ---------------------- | ||
109 | |||
110 | You must tell the kernel where the drive is at boot time. This can be | ||
111 | done at the Linux boot prompt, by using LILO, or by using Bootlin. | ||
112 | Note that this is no substitute for HOWTOs and LILO documentation, if | ||
113 | you are confused please read those for info on bootline configuration | ||
114 | and LILO. | ||
115 | |||
116 | At the linux boot prompt, press the ALT key and add the following line | ||
117 | after the boot name (you can let the kernel boot, it will tell you the | ||
118 | default boot name while booting): | ||
119 | |||
120 | cdu31a=<base address>,<interrupt>[,PAS] | ||
121 | |||
122 | The base address needs to have "0x" in front of it, since it is in | ||
123 | hex. For instance, to configure a drive at address 320 on interrupt 5, | ||
124 | use the following: | ||
125 | |||
126 | cdu31a=0x320,5 | ||
127 | |||
128 | I use the following boot line: | ||
129 | |||
130 | cdu31a=0x1f88,0,PAS | ||
131 | |||
132 | because I have a PAS-16 which does not support interrupt for the | ||
133 | CDU31A interface. | ||
134 | |||
135 | Adding this as an append line at the beginning of the /etc/lilo.conf | ||
136 | file will set it for lilo configurations. I have the following as the | ||
137 | first line in my lilo.conf file: | ||
138 | |||
139 | append="cdu31a=0x1f88,0" | ||
140 | |||
141 | I'm not sure how to set up Bootlin (I have never used it), if someone | ||
142 | would like to fill in this section please do. | ||
143 | |||
144 | |||
145 | Configuring as a Module | ||
146 | ----------------------- | ||
147 | |||
148 | The driver supports loading as a module. However, you must specify | ||
149 | the boot address and interrupt on the boot line to insmod. You can't | ||
150 | use modprobe to load it, since modprobe doesn't support setting | ||
151 | variables. | ||
152 | |||
153 | Anyway, I use the following line to load my driver as a module | ||
154 | |||
155 | /sbin/insmod /lib/modules/`uname -r`/misc/cdu31a.o cdu31a_port=0x1f88 | ||
156 | |||
157 | You can set the following variables in the driver: | ||
158 | |||
159 | cdu31a_port=<I/O address> - sets the base I/O. If hex, put 0x in | ||
160 | front of it. This must be specified. | ||
161 | |||
162 | cdu31a_irq=<interrupt> - Sets the interrupt number. Leaving this | ||
163 | off will turn interrupts off. | ||
164 | |||
165 | |||
166 | Driver Special Features | ||
167 | ----------------------- | ||
168 | |||
169 | This section describes features beyond the normal audio and CD-ROM | ||
170 | functions of the drive. | ||
171 | |||
172 | 2048 byte buffer mode | ||
173 | |||
174 | If a disk is mounted with -o block=2048, data is copied straight from | ||
175 | the drive data port to the buffer. Otherwise, the readahead buffer | ||
176 | must be involved to hold the other 1K of data when a 1K block | ||
177 | operation is done. Note that with 2048 byte blocks you cannot execute | ||
178 | files from the CD. | ||
179 | |||
180 | XA compatibility | ||
181 | |||
182 | The driver should support XA disks for both the CDU31A and CDU33A. It | ||
183 | does this transparently, the using program doesn't need to set it. | ||
184 | |||
185 | Multi-Session | ||
186 | |||
187 | A multi-session disk looks just like a normal disk to the user. Just | ||
188 | mount one normally, and all the data should be there. A special | ||
189 | thanks to Koen for help with this! | ||
190 | |||
191 | Raw sector I/O | ||
192 | |||
193 | Using the CDROMREADAUDIO it is possible to read raw audio and data | ||
194 | tracks. Both operations return 2352 bytes per sector. On the data | ||
195 | tracks, the first 12 bytes is not returned by the drive and the value | ||
196 | of that data is indeterminate. | ||

5 | |||
6 | Changes since version 0.99 | ||
7 | -------------------------- | ||
8 | - Interfacing to the kernel is routed though an extra interface layer, | ||
9 | cdrom.c. This allows runtime-configurable `behavior' of the cdrom-drive, | ||
10 | independent of the driver. | ||
11 | |||
12 | Features since version 0.33 | ||
13 | --------------------------- | ||
14 | - Full audio support, that is, both workman, workbone and cdp work | ||
15 | now reasonably. Reading TOC still takes some time. xmcd has been | ||
16 | reported to run successfully. | ||
17 | - Made auto-probe code a little better, I hope | ||
18 | |||
19 | Features since version 0.28 | ||
20 | --------------------------- | ||
21 | - Full speed transfer rate (300 kB/s). | ||
22 | - Minimum kernel memory usage for buffering (less than 3 kB). | ||
23 | - Multisession support. | ||
24 | - Tray locking. | ||
25 | - Statistics of driver accessible to the user. | ||
26 | - Module support. | ||
27 | - Auto-probing of adapter card's base port and irq line, | ||
28 | also configurable at boot time or module load time. | ||
29 | |||
30 | |||
31 | Decide how you are going to use the driver. There are two | ||
32 | options: | ||
33 | |||
34 | (a) installing the driver as a resident part of the kernel | ||
35 | (b) compiling the driver as a loadable module | ||
36 | |||
37 | Further, you must decide if you are going to specify the base port | ||
38 | address and the interrupt request line of the adapter card cm260 as | ||
39 | boot options for (a), module parameters for (b), use automatic | ||
40 | probing of these values, or hard-wire your adaptor card's settings | ||
41 | into the source code. If you don't care, you can choose | ||
42 | autoprobing, which is the default. In that case you can move on to | ||
43 | the next step. | ||
44 | |||
45 | Compiling the kernel | ||
46 | -------------------- | ||
47 | 1) move to /usr/src/linux and do a | ||
48 | |||
49 | make config | ||
50 | |||
51 | If you have chosen option (a), answer yes to CONFIG_CM206 and | ||
52 | CONFIG_ISO9660_FS. | ||
53 | |||
54 | If you have chosen option (b), answer yes to CONFIG_MODVERSIONS | ||
55 | and no (!) to CONFIG_CM206 and CONFIG_ISO9660_FS. | ||
56 | |||
57 | 2) then do a | ||
58 | |||
59 | make clean; make zImage; make modules | ||
60 | |||
61 | 3) do the usual things to install a new image (backup the old one, run | ||
62 | `rdev -R zImage 1', copy the new image in place, run lilo). Might | ||
63 | be `make zlilo'. | ||
64 | |||
65 | Using the driver as a module | ||
66 | ---------------------------- | ||
67 | If you will only occasionally use the cd-rom driver, you can choose | ||
68 | option (b), install as a loadable module. You may have to re-compile | ||
69 | the module when you upgrade the kernel to a new version. | ||
70 | |||
71 | Since version 0.96, much of the functionality has been transferred to | ||
72 | a generic cdrom interface in the file cdrom.c. The module cm206.o | ||
73 | depends on cdrom.o. If the latter is not compiled into the kernel, | ||
74 | you must explicitly load it before cm206.o: | ||
75 | |||
76 | insmod /usr/src/linux/modules/cdrom.o | ||
77 | |||
78 | To install the module, you use the command, as root | ||
79 | |||
80 | insmod /usr/src/linux/modules/cm206.o | ||
81 | |||
82 | You can specify the base address on the command line as well as the irq | ||
83 | line to be used, e.g. | ||
84 | |||
85 | insmod /usr/src/linux/modules/cm206.o cm206=0x300,11 | ||
86 | |||
87 | The order of base port and irq line doesn't matter; if you specify only | ||
88 | one, the other will have the value of the compiled-in default. You | ||
89 | may also have to install the file-system module `iso9660.o', if you | ||
90 | didn't compile that into the kernel. | ||
91 | |||
92 | |||
93 | Using the driver as part of the kernel | ||
94 | -------------------------------------- | ||
95 | If you have chosen option (a), you can specify the base-port | ||
96 | address and irq on the lilo boot command line, e.g.: | ||
97 | |||
98 | LILO: linux cm206=0x340,11 | ||
99 | |||
100 | This assumes that your linux kernel image keyword is `linux'. | ||
101 | If you specify either IRQ (3--11) or base port (0x300--0x370), | ||
102 | auto probing is turned off for both settings, thus setting the | ||
103 | other value to the compiled-in default. | ||
104 | |||
105 | Note that you can also put these parameters in the lilo configuration file: | ||
106 | |||
107 | # linux config | ||
108 | image = /vmlinuz | ||
109 | root = /dev/hda1 | ||
110 | label = Linux | ||
111 | append = "cm206=0x340,11" | ||
112 | read-only | ||
113 | |||
114 | |||
115 | If module parameters and LILO config options don't work | ||
116 | ------------------------------------------------------- | ||
117 | If autoprobing does not work, you can hard-wire the default values | ||
118 | of the base port address (CM206_BASE) and interrupt request line | ||
119 | (CM206_IRQ) into the file /usr/src/linux/drivers/cdrom/cm206.h. Change | ||
120 | the defines of CM206_IRQ and CM206_BASE. | ||
121 | |||
122 | |||
123 | Mounting the cdrom | ||
124 | ------------------ | ||
125 | 1) Make sure that the right device is installed in /dev. | ||
126 | |||
127 | mknod /dev/cm206cd b 32 0 | ||
128 | |||
129 | 2) Make sure there is a mount point, e.g., /cdrom | ||
130 | |||
131 | mkdir /cdrom | ||
132 | |||
133 | 3) mount using a command like this (run as root): | ||
134 | |||
135 | mount -rt iso9660 /dev/cm206cd /cdrom | ||
136 | |||
137 | 4) For user-mounts, add a line in /etc/fstab | ||
138 | |||
139 | /dev/cm206cd /cdrom iso9660 ro,noauto,user | ||
140 | |||
141 | This will allow users to give the commands | ||
142 | |||
143 | mount /cdrom | ||
144 | umount /cdrom | ||
145 | |||
146 | If things don't work | ||
147 | -------------------- | ||
148 | |||
149 | - Try to do a `dmesg' to find out if the driver said anything about | ||
150 | what is going wrong during the initialization. | ||
151 | |||
152 | - Try to do a `dd if=/dev/cm206cd | od -tc | less' to read from the | ||
153 | CD. | ||

2 | |||
3 | For all kind of other information about the GoldStar R420 CDROM | ||
4 | and this Linux device driver see the WWW page: | ||
5 | |||
6 | http://linux.rz.fh-hannover.de/~raupach | ||
7 | |||
8 | |||
9 | If you are the editor of a Linux CD, you should | ||
10 | enable gscd.c within your boot floppy kernel. Please, | ||
11 | send me one of your CDs for free. | ||
12 | |||
13 | |||
14 | This current driver version 0.4a only supports reading data from the disk. | ||
15 | Currently we have no audio and no multisession or XA support. | ||
16 | The polling interface is used, no DMA. | ||
17 | |||
18 | |||
19 | Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's | ||
20 | drive interface is compatible, too. | ||
21 | |||
22 | |||
23 | Installation | ||
24 | ------------ | ||
25 | |||
26 | Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert | ||
27 | the i/o address of your interface card. | ||
28 | |||
29 | The default base address is 0x340. This will work for most applications. | ||
30 | Address selection is accomplished by jumpers PN801-1 to PN801-4 on the | ||
31 | GoldStar Interface Card. | ||
32 | Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360 | ||
33 | 0x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0 | ||
34 | |||
35 | Then go back to '/usr/src/linux/' and 'make config' to build the new | ||
36 | configuration for your kernel. If you want to use the GoldStar driver | ||
37 | like a module, don't select 'GoldStar CDROM support'. By the way, you | ||
38 | have to include the iso9660 filesystem. | ||
39 | |||
40 | Now start compiling the kernel with 'make zImage'. | ||
41 | If you want to use the driver as a module, you have to do 'make modules' | ||
42 | and 'make modules_install', additionally. | ||
43 | Install your new kernel as usual - maybe you do it with 'make zlilo'. | ||
44 | |||
45 | Before you can use the driver, you have to | ||
46 | mknod /dev/gscd0 b 16 0 | ||
47 | to create the appropriate device file (you only need to do this once). | ||
48 | |||
49 | If you use modules, you can try to insert the driver. | ||
50 | Say: 'insmod /usr/src/linux/modules/gscd.o' | ||
51 | or: 'insmod /usr/src/linux/modules/gscd.o gscd=<address>' | ||
52 | The driver should report its results. | ||
53 | |||
54 | That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom' | ||
55 | |||
56 | Feel free to report errors and suggestions to the following address. | ||
57 | Be sure, I'm very happy to receive your comments! | ||

3 | Docs by Eric van der Maarel <H.T.M.v.d.Maarel@marin.nl> | ||
4 | |||
5 | This is the README for version 0.6 of the cdrom interface on an | ||
6 | ISP16, MAD16 or Mozart sound card. | ||
7 | |||
8 | The detection and configuration of this interface used to be included | ||
9 | in both the sjcd and optcd cdrom driver. Drives supported by these | ||
10 | drivers came packed with Media Magic's multi media kit, which also | ||
11 | included the ISP16 card. The idea (thanks Leo Spiekman) | ||
12 | to move it from these drivers into a separate module and moreover, not to | ||
13 | rely on the MAD16 sound driver, are as follows: | ||
14 | -duplication of code in the kernel is a waste of resources and should | ||
15 | be avoided; | ||
16 | -however, kernels and notably those included with Linux distributions | ||
17 | (cf Slackware 3.0 included version 0.5 of the isp16 configuration | ||
18 | code included in the drivers) don't always come with sound support | ||
19 | included. Especially when they already include a bunch of cdrom drivers. | ||
20 | Hence, the cdrom interface should be configurable _independently_ of | ||
21 | sound support. | ||
22 | |||
23 | The ISP16, MAD16 and Mozart sound cards have an OPTi 82C928 or an | ||
24 | OPTi 82C929 chip. The interface on these cards should work with | ||
25 | any cdrom attached to the card, which is 'electrically' compatible | ||
26 | with Sanyo/Panasonic, Sony or Mitsumi non-ide drives. However, the | ||
27 | command sets for any proprietary drives may differ | ||
28 | (and hence may not be supported in the kernel) from these four types. | ||
29 | For a fact I know the interface works and the way of configuration | ||
30 | as described in this documentation works in combination with the | ||
31 | sjcd (in Sanyo/Panasonic compatibility mode) cdrom drivers | ||
32 | (probably with the optcd (in Sony compatibility mode) as well). | ||
33 | If you have such an OPTi based sound card and you want to use the | ||
34 | cdrom interface with a cdrom drive supported by any of the other cdrom | ||
35 | drivers, it will probably work. Please let me know any experience you | ||
36 | might have). | ||
37 | I understand that cards based on the OPTi 82C929 chips may be configured | ||
38 | (hardware jumpers that is) as an IDE interface. Initialisation of such a | ||
39 | card in this mode is not supported (yet?). | ||
40 | |||
41 | The suggestion to configure the ISP16 etc. sound card by booting DOS and | ||
42 | do a warm reboot to boot Linux somehow doesn't work, at least not | ||
43 | on my machine (IPC P90), with the OPTi 82C928 based card. | ||
44 | |||
45 | Booting the kernel through the boot manager LILO allows the use | ||
46 | of some command line options on the 'LILO boot:' prompt. At boot time | ||
47 | press Alt or Shift while the LILO prompt is written on the screen and enter | ||
48 | any kernel options. Alternatively these options may be used in | ||
49 | the appropriate section in /etc/lilo.conf. Adding 'append="<cmd_line_options>"' | ||
50 | will do the trick as well. | ||
51 | The syntax of 'cmd_line_options' is | ||
52 | |||
53 | isp16=[<port>[,<irq>[,<dma>]]][[,]<drive_type>] | ||
54 | |||
55 | If there is no ISP16 or compatibles detected, there's probably no harm done. | ||
56 | These options indicate the values that your cdrom drive has been (or will be) | ||
57 | configured to use. | ||
58 | Valid values for the base i/o address are: | ||
59 | port=0x340,0x320,0x330,0x360 | ||
60 | for the interrupt request number | ||
61 | irq=0,3,5,7,9,10,11 | ||
62 | for the direct memory access line | ||
63 | dma=0,3,5,6,7 | ||
64 | and for the type of drive | ||
65 | drive_type=noisp16,Sanyo,Panasonic,Sony,Mitsumi. | ||
66 | Note that these options are case sensitive. | ||
67 | The values 0 for irq and dma indicate that they are not used, and | ||
68 | the drive will be used in 'polling' mode. The values 5 and 7 for irq | ||
69 | should be avoided in order to avoid any conflicts with optional | ||
70 | sound card configuration. | ||
71 | The syntax of the command line does not allow the specification of | ||
72 | irq when there's nothing specified for the base address and no | ||
73 | specification of dma when there is no specification of irq. | ||
74 | The value 'noisp16' for drive_type, which may be used as the first | ||
75 | non-integer option value (e.g. 'isp16=noisp16'), makes sure that probing | ||
76 | for and subsequent configuration of an ISP16-compatible card is skipped | ||
77 | all together. This can be useful to overcome possible conflicts which | ||
78 | may arise while the kernel is probing your hardware. | ||
79 | The default values are | ||
80 | port=0x340 | ||
81 | irq=0 | ||
82 | dma=0 | ||
83 | drive_type=Sanyo | ||
84 | reflecting my own configuration. The defaults can be changed in | ||
85 | the file linux/drivers/cdrom/ips16.h. | ||
86 | |||
87 | The cdrom interface can be configured at run time by loading the | ||
88 | initialisation driver as a module. In that case, the interface | ||
89 | parameters can be set by giving appropriate values on the command | ||
90 | line. Configuring the driver can then be done by the following | ||
91 | command (assuming you have iso16.o installed in a proper place): | ||
92 | |||
93 | insmod isp16.o isp16_cdrom_base=<port> isp16_cdrom_irq=<irq> \ | ||
94 | isp16_cdrom_dma=<dma> isp16_cdrom_type=<drive_type> | ||
95 | |||
96 | where port, irq, dma and drive_type can have any of the values mentioned | ||
97 | above. | ||
98 | |||
99 | |||
100 | Have fun! | ||

1 | This is the README file for the Optics Storage 8000 AT CDROM device driver. | ||
2 | |||
3 | This is the driver for the so-called 'DOLPHIN' drive, with the 34-pin | ||
4 | Sony-compatible interface. For the IDE-compatible Optics Storage 8001 | ||
5 | drive, you will want the ATAPI CDROM driver. The driver also seems to | ||
6 | work with the Lasermate CR328A. If you have a drive that works with | ||
7 | this driver, and that doesn't report itself as DOLPHIN, please drop me | ||
8 | a mail. | ||
9 | |||
10 | The support for multisession CDs is in ALPHA stage. If you use it, | ||
11 | please mail me your experiences. Multisession support can be disabled | ||
12 | at compile time. | ||
13 | |||
14 | You can find some older versions of the driver at | ||
15 | dutette.et.tudelft.nl:/pub/linux/ | ||
16 | and at Eberhard's mirror | ||
17 | ftp.gwdg.de:/pub/linux/cdrom/drivers/optics/ | ||
18 | |||
19 | Before you can use the driver, you have to create the device file once: | ||
20 | # mknod /dev/optcd0 b 17 0 | ||
21 | |||
22 | To specify the base address if the driver is "compiled-in" to your kernel, | ||
23 | you can use the kernel command line item (LILO option) | ||
24 | optcd=0x340 | ||
25 | with the right address. | ||
26 | |||
27 | If you have compiled optcd as a module, you can load it with | ||
28 | # insmod /usr/src/linux/modules/optcd.o | ||
29 | or | ||
30 | # insmod /usr/src/linux/modules/optcd.o optcd=0x340 | ||
31 | with the matching address value of your interface card. | ||
32 | |||
33 | The driver employs a number of buffers to do read-ahead and block size | ||
34 | conversion. The number of buffers is configurable in optcd.h, and has | ||
35 | influence on the driver performance. For my machine (a P75), 6 buffers | ||
36 | seems optimal, as can be seen from this table: | ||
37 | |||
38 | #bufs kb/s %cpu | ||
39 | 1 97 0.1 | ||
40 | 2 191 0.3 | ||
41 | 3 188 0.2 | ||

45 | 7 281 7.0 | ||
46 | 8 246 2.8 | ||
47 | 16 281 3.4 | ||
48 | |||
49 | If you get a throughput significantly below 300 kb/s, try tweaking | ||
50 | N_BUFS, and don't forget to mail me your results! | ||
51 | |||
52 | I'd appreciate success/failure reports. If you find a bug, try | ||
53 | recompiling the driver with some strategically chosen debug options | ||
54 | (these can be found in optcd.h) and include the messages generated in | ||
55 | your bug report. Good luck. | ||

1 | This README belongs to release 4.2 or newer of the SoundBlaster Pro | ||
2 | (Matsushita, Kotobuki, Panasonic, CreativeLabs, Longshine and Teac) | ||
3 | CD-ROM driver for Linux. | ||
4 | |||
5 | sbpcd really, really is NOT for ANY IDE/ATAPI drive! | ||
6 | Not even if you have an "original" SoundBlaster card with an IDE interface! | ||
7 | So, you'd better have a look into README.ide if your port address is 0x1F0, | ||
8 | 0x170, 0x1E8, 0x168 or similar. | ||
9 | I get tons of mails from IDE/ATAPI drive users - I really can't continue | ||
10 | any more to answer them all. So, if your drive/interface information sheets | ||
11 | mention "IDE" (primary, secondary, tertiary, quaternary) and the DOS driver | ||
12 | invoking line within your CONFIG.SYS is using an address below 0x230: | ||
13 | DON'T ROB MY LAST NERVE - jumper your interface to address 0x170 and IRQ 15 | ||
14 | (that is the "secondary IDE" configuration), set your drive to "master" and | ||
15 | use ide-cd as your driver. If you do not have a second IDE hard disk, use the | ||
16 | LILO commands | ||
17 | hdb=noprobe hdc=cdrom | ||
18 | and get lucky. | ||
19 | To make it fully clear to you: if you mail me about IDE/ATAPI drive problems, | ||
20 | my answer is above, and I simply will discard your mail, hoping to stop the | ||
21 | flood and to find time to lead my 12-year old son towards happy computing. | ||
22 | |||
23 | The driver is able to drive the whole family of "traditional" AT-style (that | ||
24 | is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita, | ||
25 | Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The | ||
26 | well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563. | ||
27 | CR-574 is an IDE/ATAPI drive. | ||
28 | |||
29 | The Longshine LCS-7260 is a double-speed drive which uses the "old" | ||
30 | Matsushita command set. It is supported - with help by Serge Robyns. | ||
31 | Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support | ||
32 | has started; get in contact if you have such a "Vertos 100" or "ECS-AT" | ||
33 | drive. | ||
34 | |||
35 | There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563 | ||
36 | with a special controller board. This drive is supported (the interface is | ||
37 | of the "LaserMate" type), and it is possibly the best buy today (cheaper than | ||
38 | an internal drive, and you can use it as an internal, too - e.g. plug it into | ||
39 | a soundcard). | ||
40 | |||
41 | CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter | ||
42 | is made by Funai and sometimes named "E2550UA", newer models may be named | ||
43 | "MK4015". The CD200F drives should fully work. | ||
44 | CD200 drives without "F" are still giving problems: drive detection and | ||
45 | playing audio should work, data access will result in errors. I need qualified | ||
46 | feedback about the bugs within the data functions or a drive (I never saw a | ||
47 | CD200). | ||
48 | |||
49 | The quad-speed Teac CD-55A drive is supported, but still does not reach "full | ||
50 | speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES | ||
51 | to 64 (it is not recommended to do that for normal "file access" usage, but it | ||
52 | can speed up things a lot if you use something like "dd" to read from the | ||
53 | drive; I use it for verifying self-written CDs this way). | ||
54 | The drive itself is able to deliver 600 kB/sec, so this needs | ||
55 | work; with the normal setup, the performance currently is not even as good as | ||
56 | double-speed. | ||
57 | |||
58 | This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives, | ||
59 | and again: this driver is in no way usable for any IDE/ATAPI drive. If you | ||
60 | think your drive should work and it doesn't: send me the DOS driver for your | ||
61 | beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help, | ||
62 | and include an original log message excerpt, and try to give all information | ||
63 | a complete idiot needs to understand your hassle already with your first | ||
64 | mail. And if you want to say "as I have mailed you before", be sure that I | ||
65 | don't remember your "case" by such remarks; at the moment, I have some | ||
66 | hundreds of open correspondences about Linux CDROM questions (hope to reduce if | ||
67 | the IDE/ATAPI user questions disappear). | ||
68 | |||
69 | |||
70 | This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy, | ||
71 | SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P, | ||
72 | LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...). | ||
73 | |||
74 | It works with the "configurable" interface "Sequoia S-1000", too, which is | ||
75 | used on the Spea Media FX and Ensonic Soundscape sound cards. You have to | ||
76 | specify the type "SBPRO 2" and the true CDROM port address with it, not the | ||
77 | "configuration port" address. | ||
78 | |||
79 | If you have a sound card which needs a "configuration driver" instead of | ||
80 | jumpers for interface types and addresses (like Mozart cards) - those | ||
81 | drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical | ||
82 | names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the | ||
83 | CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c | ||
84 | are just for you!). Hannu Savolainen's mad16.c code is able to set up my | ||
85 | Mozart card - I simply had to add | ||
86 | #define MAD16_CONF 0x06 | ||
87 | #define MAD16_CDSEL 0x03 | ||
88 | to configure the CDROM interface for type "Panasonic" (LaserMate) and address | ||
89 | 0x340. | ||
90 | |||
91 | The interface type has to get configured in linux/drivers/cdrom/sbpcd.h, | ||
92 | because the register layout is different between the "SoundBlaster" and the | ||
93 | "LaserMate" type. | ||
94 | |||
95 | I got a report that the Teac interface card "I/F E117098" is of type | ||
96 | "SoundBlaster" (i.e. you have to set SBPRO to 1) even with the addresses | ||
97 | 0x300 and above. This is unusual, and it can't get covered by the auto | ||
98 | probing scheme. | ||
99 | The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0) | ||
100 | need the SBPRO 3 setup. | ||
101 | |||
102 | If auto-probing found the drive, the address is correct. The reported type | ||
103 | may be wrong. A "mount" will give success only if the interface type is set | ||
104 | right. Playing audio should work with a wrong set interface type, too. | ||
105 | |||
106 | With some Teac and some CD200 drives I have seen interface cards which seem | ||
107 | to lack the "drive select" lines; always drive 0 gets addressed. To avoid | ||
108 | "mirror drives" (four drives detected where you only have one) with such | ||
109 | interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if | ||
110 | possible). | ||
111 | |||
112 | |||
113 | Up to 4 drives per interface card, and up to 4 interface cards are supported. | ||
114 | All supported drive families can be mixed, but the CR-521 drives are | ||
115 | hard-wired to drive ID 0. The drives have to use different drive IDs, and each | ||
116 | drive has to get a unique minor number (0...3), corresponding indirectly to | ||
117 | its drive ID. | ||
118 | The drive IDs may be selected freely from 0 to 3 - they do not have to be in | ||
119 | consecutive order. | ||
120 | |||
121 | As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible | ||
122 | to change old drives to any ID, too. He writes in this sense: | ||
123 | "In order to be able to use more than one single speed drive | ||
124 | (they do not have the ID jumpers) you must add a DIP switch | ||
125 | and two resistors. The pads are already on the board next to | ||
126 | the power connector. You will see the silkscreen for the | ||
127 | switch if you remove the top cover. | ||
128 | 1 2 3 4 | ||
129 | ID 0 = x F F x O = "on" | ||
130 | ID 1 = x O F x F = "off" | ||
131 | ID 2 = x F O x x = "don't care" | ||
132 | ID 3 = x O O x | ||
133 | Next to the switch are the positions for R76 (7k) and R78 | ||
134 | (12k). I had to play around with the resistor values - ID 3 | ||
135 | did not work with other values. If the values are not good, | ||
136 | ID 3 behaves like ID 0." | ||
137 | |||
138 | To use more than 4 drives, you simply need a second controller card at a | ||
139 | different address and a second cable. | ||
140 | |||
141 | The driver supports reading of data from the CD and playing of audio tracks. | ||
142 | The audio part should run with WorkMan, xcdplayer, with the "non-X11" products | ||
143 | CDplayer and WorkBone - tell me if it is not compatible with other software. | ||
144 | The only accepted measure for correctness with the audio functions is the | ||
145 | "cdtester" utility (appended) - most audio player programmers seem to be | ||
146 | better musicians than programmers. ;-) | ||
147 | |||
148 | With the CR-56x and the CD200 drives, the reading of audio frames is possible. | ||
149 | This is implemented by an IOCTL function which reads READ_AUDIO frames of | ||
150 | 2352 bytes at once (configurable with the "READ_AUDIO" define, default is 0). | ||
151 | Reading the same frame a second time gives different data; the frame data | ||
152 | start at a different position, but all read bytes are valid, and we always | ||
153 | read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame | ||
154 | at once possibly misses some chunks at each frame boundary. This lack has to | ||
155 | get corrected by external, "higher level" software which reads the same frame | ||
156 | again and tries to find and eliminate overlapping chunks (24-byte-pieces). | ||
157 | |||
158 | The transfer rate with reading audio (1-frame-pieces) currently is very slow. | ||
159 | This can be better reading bigger chunks, but the "missing" chunks possibly | ||
160 | occur at the beginning of each single frame. | ||
161 | The software interface possibly may change a bit the day the SCSI driver | ||
162 | supports it too. | ||
163 | |||
164 | With all but the CR-52x drives, MultiSession is supported. | ||
165 | Photo CDs work (the "old" drives like CR-521 can access only the first | ||
166 | session of a photoCD). | ||
167 | At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to | ||
168 | convert photo CD image files and Gerd Knorr's viewing utility. | ||
169 | |||
170 | The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with | ||
171 | CR-56x drives, and currently not more than 500 kB/sec (usually less than | ||
172 | 250 kB/sec) with the Teac quad speed drives. | ||
173 | XA (PhotoCD) disks with "old" drives give only 50 kB/sec. | ||
174 | |||
175 | This release consists of | ||
176 | - this README file | ||
177 | - the driver file linux/drivers/cdrom/sbpcd.c | ||
178 | - the stub files linux/drivers/cdrom/sbpcd[234].c | ||
179 | - the header file linux/drivers/cdrom/sbpcd.h. | ||
180 | |||
181 | |||
182 | To install: | ||
183 | ----------- | ||
184 | |||
185 | 1. Setup your hardware parameters. Though the driver does "auto-probing" at a | ||
186 | lot of (not all possible!) addresses, this step is recommended for | ||
187 | everyday use. You should let sbpcd auto-probe once and use the reported | ||
188 | address if a drive got found. The reported type may be incorrect; it is | ||
189 | correct if you can mount a data CD. There is no choice for you with the | ||
190 | type; only one is right, the others are deadly wrong. | ||
191 | |||
192 | a. Go into /usr/src/linux/drivers/cdrom/sbpcd.h and configure it for your | ||
193 | hardware (near the beginning): | ||
194 | a1. Set it up for the appropriate type of interface board. | ||
195 | "Original" CreativeLabs sound cards need "SBPRO 1". | ||
196 | Most "compatible" sound cards (almost all "non-CreativeLabs" cards) | ||
197 | need "SBPRO 0". | ||
198 | The "no-sound" board from OmniCd needs the "SBPRO 1" setup. | ||
199 | The Teac 8-bit "no-sound" boards need the "SBPRO 1" setup. | ||
200 | The Teac 16-bit "no-sound" boards need the "SBPRO 3" setup. | ||
201 | All other "no-sound" boards need the "SBPRO 0" setup. | ||
202 | The Spea Media FX and Ensoniq SoundScape cards need "SBPRO 2". | ||
203 | sbpcd.c holds some examples in its auto-probe list. | ||
204 | If you configure "SBPRO" wrong, the playing of audio CDs will work, | ||
205 | but you will not be able to mount a data CD. | ||
206 | a2. Tell the address of your CDROM_PORT (not of the sound port). | ||
207 | a3. If 4 drives get found, but you have only one, set MAX_DRIVES to 1. | ||
208 | a4. Set DISTRIBUTION to 0. | ||
209 | b. Additionally for 2.a1 and 2.a2, the setup may be done during | ||
210 | boot time (via the "kernel command line" or "LILO option"): | ||
211 | sbpcd=0x320,LaserMate | ||
212 | or | ||
213 | sbpcd=0x230,SoundBlaster | ||
214 | or | ||
215 | sbpcd=0x338,SoundScape | ||
216 | or | ||
217 | sbpcd=0x2C0,Teac16bit | ||
218 | This is especially useful if you install a fresh distribution. | ||
219 | If the second parameter is a number, it gets taken as the type | ||
220 | setting; 0 is "LaserMate", 1 is "SoundBlaster", 2 is "SoundScape", | ||
221 | 3 is "Teac16bit". | ||
222 | So, for example | ||
223 | sbpcd=0x230,1 | ||
224 | is equivalent to | ||
225 | sbpcd=0x230,SoundBlaster | ||
226 | |||
227 | 2. "cd /usr/src/linux" and do a "make config" and select "y" for Matsushita | ||
228 | CD-ROM support and for ISO9660 FileSystem support. If you do not have a | ||
229 | second, third, or fourth controller installed, do not say "y" to the | ||
230 | secondary Matsushita CD-ROM questions. | ||
231 | |||
232 | 3. Then make the kernel image ("make zlilo" or similar). | ||
233 | |||
234 | 4. Make the device file(s). This step usually already has been done by the | ||
235 | MAKEDEV script. | ||
236 | The driver uses MAJOR 25, so, if necessary, do | ||
237 | mknod /dev/sbpcd b 25 0 (if you have only one drive) | ||
238 | and/or | ||
239 | mknod /dev/sbpcd0 b 25 0 | ||
240 | mknod /dev/sbpcd1 b 25 1 | ||
241 | mknod /dev/sbpcd2 b 25 2 | ||
242 | mknod /dev/sbpcd3 b 25 3 | ||
243 | to make the node(s). | ||
244 | |||
245 | The "first found" drive gets MINOR 0 (regardless of its jumpered ID), the | ||
246 | "next found" (at the same cable) gets MINOR 1, ... | ||
247 | |||
248 | For a second interface board, you have to make nodes like | ||
249 | mknod /dev/sbpcd4 b 26 0 | ||
250 | mknod /dev/sbpcd5 b 26 1 | ||
251 | and so on. Use the MAJORs 26, 27, 28. | ||
252 | |||
253 | If you further make a link like | ||
254 | ln -s sbpcd /dev/cdrom | ||
255 | you can use the name /dev/cdrom, too. | ||
256 | |||
257 | 5. Reboot with the new kernel. | ||
258 | |||
259 | You should now be able to do | ||
260 | mkdir /CD | ||
261 | and | ||
262 | mount -rt iso9660 /dev/sbpcd /CD | ||
263 | or | ||
264 | mount -rt iso9660 -o block=2048 /dev/sbpcd /CD | ||
265 | and see the contents of your CD in the /CD directory. | ||
266 | To use audio CDs, a mounting is not recommended (and it would fail if the | ||
267 | first track is not a data track). | ||
268 | |||
269 | |||
270 | Using sbpcd as a "loadable module": | ||
271 | ----------------------------------- | ||
272 | |||
273 | If you do NOT select "Matsushita/Panasonic CDROM driver support" during the | ||
274 | "make config" of your kernel, you can build the "loadable module" sbpcd.o. | ||
275 | |||
276 | If sbpcd gets used as a module, the support of more than one interface | ||
277 | card (i.e. drives 4...15) is disabled. | ||
278 | |||
279 | You can specify interface address and type with the "insmod" command like: | ||
280 | # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0 | ||
281 | or | ||
282 | # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1 | ||
283 | or | ||
284 | # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2 | ||
285 | where the last number represents the SBPRO setting (no strings allowed here). | ||
286 | |||
287 | |||
288 | Things of interest: | ||
289 | ------------------- | ||
290 | |||
291 | The driver is configured to try the LaserMate type of interface at I/O port | ||
292 | 0x0340 first. If this is not appropriate, sbpcd.h should get changed | ||
293 | (you will find the right place - just at the beginning). | ||
294 | |||
295 | No DMA and no IRQ is used. | ||
296 | |||
297 | To reduce or increase the amount of kernel messages, edit sbpcd.c and play | ||
298 | with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug"). | ||
299 | Don't forget to reflect on what you do; enabling all DBG_xxx switches at once | ||
300 | may crash your system, and each message line is accompanied by a delay. | ||
301 | |||
302 | The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to | ||
303 | specify "block=2048" as a mount option. Doing this will disable the direct | ||
304 | execution of a binary from the CD; you have to copy it to a device with the | ||
305 | standard BLOCK_SIZE (1024) first. So, do not use this if your system is | ||
306 | directly "running from the CDROM" (like some of Yggdrasil's installation | ||
307 | variants). There are CDs on the market (like the German "unifix" Linux | ||
308 | distribution) which MUST get handled with a block_size of 1024. Generally, | ||
309 | one can say all the CDs which hold files of the name YMTRANS.TBL are defective; | ||
310 | do not use block=2048 with those. | ||
311 | |||
312 | Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With | ||
313 | these, you can configure the driver for some special things. | ||
314 | You can use the appended program "cdtester" to set the auto-eject feature | ||
315 | during runtime. Jeff Tranter's "eject" utility can do this, too (and more) | ||
316 | for you. | ||
317 | |||
318 | There is an ioctl CDROMMULTISESSION to obtain with a user program if | ||
319 | the CD is an XA disk and - if it is - where the last session starts. The | ||
320 | "cdtester" program illustrates how to call it. | ||
321 | |||
322 | |||
323 | Auto-probing at boot time: | ||
324 | -------------------------- | ||
325 | |||
326 | The driver does auto-probing at many well-known interface card addresses, | ||
327 | but not all: | ||
328 | Some probings can cause a hang if an NE2000 ethernet card gets touched, because | ||
329 | SBPCD's auto-probing happens before the initialization of the net drivers. | ||
330 | Those "hazardous" addresses are excluded from auto-probing; the "kernel | ||
331 | command line" feature has to be used during installation if you have your | ||
332 | drive at those addresses. The "module" version is allowed to probe at those | ||
333 | addresses, too. | ||
334 | |||
335 | The auto-probing looks first at the configured address resp. the address | ||
336 | submitted by the kernel command line. With this, it is possible to use this | ||
337 | driver within installation boot floppies, and for any non-standard address, | ||
338 | too. | ||
339 | |||
340 | Auto-probing will make an assumption about the interface type ("SBPRO" or not), | ||
341 | based upon the address. That assumption may be wrong (initialization will be | ||
342 | o.k., but you will get I/O errors during mount). In that case, use the "kernel | ||
343 | command line" feature and specify address & type at boot time to find out the | ||
344 | right setup. | ||
345 | |||
346 | For everyday use, address and type should get configured within sbpcd.h. That | ||
347 | will stop the auto-probing due to success with the first try. | ||
348 | |||
349 | The kernel command "sbpcd=0" suppresses each auto-probing and causes | ||
350 | the driver not to find any drive; it is meant for people who love sbpcd | ||
351 | so much that they do not want to miss it, even if they miss the drives. ;-) | ||
352 | |||
353 | If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is | ||
354 | initially disabled and needs an explicit kernel command to get activated. | ||
355 | Once activated, it does not stop before success or end-of-list. This may be | ||
356 | useful within "universal" CDROM installation boot floppies (but using the | ||
357 | loadable module would be better because it allows an "extended" auto-probing | ||
358 | without fearing NE2000 cards). | ||
359 | |||
360 | To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within | ||
361 | sbpcd.h. | ||
362 | |||
363 | |||
364 | Setting up address and interface type: | ||
365 | -------------------------------------- | ||
366 | |||
367 | If your I/O port address is not 0x340, you have to look for the #defines near | ||
368 | the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and | ||
369 | change CDROM_PORT to the address of your CDROM I/O port. | ||
370 | |||
371 | Almost all of the "SoundBlaster compatible" cards behave like the no-sound | ||
372 | interfaces, i.e. need SBPRO 0! | ||
373 | |||
374 | With "original" SB Pro cards, an initial setting of CD_volume through the | ||
375 | sound card's MIXER register gets done. | ||
376 | If you are using a "compatible" sound card of types "LaserMate" or "SPEA", | ||
377 | you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too... | ||
378 | |||
379 | |||
380 | Using audio CDs: | ||
381 | ---------------- | ||
382 | |||
383 | Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see | ||
384 | README.aztcd from the Aztech driver package) should work. | ||
385 | |||
386 | The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants | ||
387 | "/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the | ||
388 | appropriate links to use them without the need to supply parameters. | ||
389 | |||
390 | |||
391 | Copying audio tracks: | ||
392 | --------------------- | ||
393 | |||
394 | The following program will copy track 1 (or a piece of it) from an audio CD | ||
395 | into the file "track01": | ||
396 | |||
397 | /*=================== begin program ========================================*/ | ||
398 | /* | ||
399 | * read an audio track from a CD | ||
400 | * | ||
401 | * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de> | ||
402 | * may be used & enhanced freely | ||
403 | * | ||
404 | * Due to non-existent sync bytes at the beginning of each audio frame (or due | ||
405 | * to a firmware bug within all known drives?), it is currently a kind of | ||
406 | * fortune if two consecutive frames fit together. | ||
407 | * Usually, they overlap, or a little piece is missing. This happens in units | ||
408 | * of 24-byte chunks. It has to get fixed by higher-level software (reading | ||
409 | * until an overlap occurs, and then eliminate the overlapping chunks). | ||
410 | * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of | ||
411 | * such an algorithm. | ||
412 | * This example program further is missing to obtain the SubChannel data | ||
413 | * which belong to each frame. | ||
414 | * | ||
415 | * This is only an example of the low-level access routine. The read data are | ||
416 | * pure 16-bit CDDA values; they have to get converted to make sound out of | ||
417 | * them. | ||
418 | * It is no fun to listen to it without prior overlap/underlap correction! | ||

529 | Known problems: | ||
530 | --------------- | ||
531 | |||
532 | Currently, the detection of disk change or removal is actively disabled. | ||
533 | |||
534 | Most attempts to read the UPC/EAN code result in a stream of zeroes. All my | ||
535 | drives are mostly telling there is no UPC/EAN code on disk or there is, but it | ||
536 | is an all-zero number. I guess now almost no CD holds such a number. | ||

8 | |||
9 | This is the README for the sjcd cdrom driver, version 1.6. | ||
10 | |||
11 | This file is meant as a tips & tricks edge for the usage of the SANYO CDR-H94A | ||
12 | cdrom drive. It will grow as the questions arise. ;-) | ||
13 | For info on configuring the ISP16 sound card look at Documentation/cdrom/isp16. | ||
14 | |||
15 | The driver should work with any of the Panasonic, Sony or Mitsumi style | ||
16 | CDROM interfaces. | ||
17 | The cdrom interface on Media Magic's soft configurable sound card ISP16, | ||
18 | which used to be included in the driver, is now supported in a separate module. | ||
19 | This initialisation module will probably also work with other interfaces | ||
20 | based on an OPTi 82C928 or 82C929 chip (like MAD16 and Mozart): see the | ||
21 | documentation Documentation/cdrom/isp16. | ||
22 | |||
23 | The device major for sjcd is 18, and minor is 0. Create a block special | ||
24 | file in your /dev directory (e.g., /dev/sjcd) with these numbers. | ||
25 | (For those who don't know, being root and doing the following should do | ||
26 | the trick: | ||
27 | mknod -m 644 /dev/sjcd b 18 0 | ||
28 | and mount the cdrom by /dev/sjcd). | ||
29 | |||
30 | The default configuration parameters are: | ||
31 | base address 0x340 | ||
32 | no irq | ||
33 | no dma | ||
34 | (Actually the CDR-H94A doesn't know how to use irq and dma.) | ||
35 | As of version 1.2, setting base address at boot time is supported | ||
36 | through the use of command line options: type at the "boot:" prompt: | ||
37 | linux sjcd=<base_address> | ||
38 | (where you would use the kernel labeled "linux" in lilo's configuration | ||
39 | file /etc/lilo.conf). You could also use 'append="sjcd=<configuration_info>"' | ||
40 | in the appropriate section of /etc/lilo.conf | ||
41 | If you're building a kernel yourself you can set your default base | ||
42 | i/o address with SJCD_BASE_ADDR in /usr/src/linux/drivers/cdrom/sjcd.h. | ||
43 | |||
44 | The sjcd driver supports being loaded as a module. The following | ||
45 | command will set the base i/o address on the fly (assuming you | ||
46 | have installed the module in an appropriate place). | ||
47 | insmod sjcd.o sjcd_base=<base_address> | ||

1 | README FOR LINUX SONY CDU-535/531 DRIVER | ||
2 | ======================================== | ||
3 | |||
4 | This is the Sony CDU-535 (and 531) driver version 0.7 for Linux. | ||
5 | I do not think I have the documentation to add features like DMA support | ||
6 | so if anyone else wants to pursue it or help me with it, please do. | ||
7 | (I need to see what was done for the CDU-31A driver -- perhaps I can | ||
8 | steal some of that code.) | ||
9 | |||
10 | This is a Linux device driver for the Sony CDU-535 CDROM drive. This is | ||
11 | one of the older Sony drives with its own interface card (Sony bus). | ||
12 | The DOS driver for this drive is named SONY_CDU.SYS - when you boot DOS | ||
13 | your drive should be identified as a SONY CDU-535. The driver works | ||
14 | with a CDU-531 also. One user reported that the driver worked on drives | ||
15 | OEM'ed by Procomm, drive and interface board were labelled Procomm. | ||
16 | |||
17 | The Linux driver is based on Corey Minyard's sonycd 0.3 driver for | ||
18 | the CDU-31A. Ron Jeppesen just changed the commands that were sent | ||
19 | to the drive to correspond to the CDU-535 commands and registers. | ||
20 | There were enough changes to let bugs creep in but it seems to be stable. | ||
21 | Ron was able to tar an entire CDROM (should read all blocks) and built | ||
22 | ghostview and xfig off Walnut Creek's X11R5/GNU CDROM. xcdplayer and | ||
23 | workman work with the driver. Others have used the driver without | ||
24 | problems except those dealing with wait loops (fixed in third release). | ||
25 | Like Minyard's original driver this one uses a polled interface (this | ||
26 | is also the default setup for the DOS driver). It has not been tried | ||
27 | with interrupts or DMA enabled on the board. | ||
28 | |||
29 | REQUIREMENTS | ||
30 | ============ | ||
31 | |||
32 | - Sony CDU-535 drive, preferably without interrupts and DMA | ||
33 | enabled on the card. | ||
34 | |||
35 | - Drive must be set up as unit 1. Only the first unit will be | ||
36 | recognized | ||
37 | |||
38 | - You must enter your interface address into | ||
39 | /usr/src/linux/drivers/cdrom/sonycd535.h and build the | ||
40 | appropriate kernel or use the "kernel command line" parameter | ||
41 | sonycd535=0x320 | ||
42 | with the correct interface address. | ||
43 | |||
44 | NOTES: | ||
45 | ====== | ||
46 | |||
47 | 1) The drive MUST be turned on when booting or it will not be recognized! | ||
48 | (but see comments on modularized version below) | ||
49 | |||
50 | 2) when the cdrom device is opened the eject button is disabled to keep the | ||
51 | user from ejecting a mounted disk and replacing it with another. | ||
52 | Unfortunately xcdplayer and workman also open the cdrom device so you | ||
53 | have to use the eject button in the software. Keep this in mind if your | ||
54 | cdrom player refuses to give up its disk -- exit workman or xcdplayer, or | ||
55 | umount the drive if it has been mounted. | ||
56 | |||
57 | THANKS | ||
58 | ====== | ||
59 | |||
60 | Many thanks to Ron Jeppesen (ronj.an@site007.saic.com) for getting | ||
61 | this project off the ground. He wrote the initial release | ||
62 | and the first two patches to this driver (0.1, 0.2, and 0.3). | ||
63 | Thanks also to Eberhard Moenkeberg (emoenke@gwdg.de) for prodding | ||
64 | me to place this code into the mainstream Linux source tree | ||
65 | (as of Linux version 1.1.91), as well as some patches to make | ||
66 | it a better device citizen. Further thanks to Joel Katz | ||
67 | <joelkatz@webchat.org> for his MODULE patches (see details below), | ||
68 | Porfiri Claudio <C.Porfiri@nisms.tei.ericsson.se> for patches | ||
69 | to make the driver work with the older CDU-510/515 series, and | ||
70 | Heiko Eissfeldt <heiko@colossus.escape.de> for pointing out that | ||
71 | the verify_area() checks were ignoring the results of said checks | ||
72 | (note: verify_area() has since been replaced by access_ok()). | ||
73 | |||
74 | (Acknowledgments from Ron Jeppesen in the 0.3 release:) | ||
75 | Thanks to Corey Minyard who wrote the original CDU-31A driver on which | ||
76 | this driver is based. Thanks to Ken Pizzini and Bob Blair who provided | ||
77 | patches and feedback on the first release of this driver. | ||

82 | ------------------------------------------------------------------------------ | ||
83 | (The following is from Joel Katz <joelkatz@webchat.org>.) | ||
84 | |||
85 | To build a version of sony535.o that can be installed as a module, | ||
86 | use the following command: | ||
87 | |||
88 | gcc -c -D__KERNEL__ -DMODULE -O2 sonycd535.c -o sonycd535.o | ||
89 | |||
90 | To install the module, simply type: | ||
91 | |||
92 | insmod sony535.o | ||
93 | or | ||
94 | insmod sony535.o sonycd535=<address> | ||
95 | |||
96 | And to remove it: | ||
97 | |||
98 | rmmod sony535 | ||
99 | |||
100 | The code checks to see if MODULE is defined and behaves as it used | ||
101 | to if MODULE is not defined. That means your patched file should behave | ||
102 | exactly as it used to if compiled into the kernel. | ||
103 | |||
104 | I have an external drive, and I usually leave it powered off. I used | ||
105 | to have to reboot if I needed to use the CDROM drive. Now I don't. | ||
106 | |||
107 | Even if you have an internal drive, why waste the 96K of memory | ||
108 | (unswappable) that the driver uses if you use your CD-ROM drive infrequently? | ||
109 | |||
110 | This driver will not install (whether compiled in or loaded as a | ||
111 | module) if the CDROM drive is not available during its initialization. This | ||
112 | means that you can have the driver compiled into the kernel and still load | ||
113 | the module later (assuming the driver doesn't install itself during | ||
114 | power-on). This only wastes 12K when you boot with the CDROM drive off. | ||
115 | |||
116 | This is what I usually do; I leave the driver compiled into the | ||
117 | kernel, but load it as a module if I powered the system up with the drive | ||
118 | off and then later decided to use the CDROM drive. | ||
119 | |||
120 | Since the driver only uses a single page to point to the chunks, | ||
121 | attempting to set the buffer cache to more than 2 Megabytes would be very | ||
122 | bad; don't do that. | ||
