12 ISA-AT-bus card).
13 IT WILL DEFINITELY NOT WORK WITH CD-ROM DRIVES WITH *IDE*-INTERFACE,
14 such as the Aztech CDA269-031SE !!! (The only known exceptions are
15 'faked' IDE drives like the CyCDROM CR520ie which work with aztcd
16 under certain conditions, see 7.). IF YOU'RE USING A CD-ROM DRIVE
17 WITH IDE-INTERFACE, SOMETIMES ALSO CALLED ATAPI-COMPATIBLE, PLEASE
18 USE THE ide-cd.c DRIVER, WRITTEN BY MARK LORD AND SCOTT SNYDER !
19 THE STANDARD-KERNEL 1.2.x NOW ALSO SUPPORTS IDE-CDROM-DRIVES, SEE THE

431. NOTE
44This software has been successfully in alpha and beta test and is part of
45the standard kernel since kernel 1.1.8x since December 1994. It works with
46AZTECH 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
48versions 1.0.9 and newer. But with any software there still may be bugs in it.
49So if you encounter problems, you are invited to help us improve this software.
50Please send me a detailed bug report (see chapter BUG REPORTS). You are also
51invited in helping us to increase the number of drives, which are supported.
52
53Please read the README-files carefully and always keep a backup copy of your
54old kernel, in order to reboot if something goes wrong!
55
562. INSTALLATION
57The driver consists of a header file 'aztcd.h', which normally should reside
58in /usr/src/linux/drivers/cdrom and the source code 'aztcd.c', which normally
59resides in the same place. It uses /dev/aztcd (/dev/aztcd0 in some distri-
60butions), which must be a valid block device with major number 29 and reside
61in directory /dev. To mount a CD-ROM, your kernel needs to have the ISO9660-
62filesystem support included.
63
64PLEASE NOTE: aztcd.c has been developed in parallel to the linux kernel,
65which had and is having many major and minor changes which are not backward
66compatible. Quite definitely aztcd.c version 1.80 and newer will NOT work
67in kernels older than 1.3.33. So please always use the most recent version
68of aztcd.c with the appropriate linux-kernel.
69
703. CONFIGURING YOUR KERNEL
71If your kernel is already configured for using the AZTECH driver you will
72see 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
77If the message looks different and you are sure to have a supported drive,
78it may have a different base address. The Aztech driver does look for the
79CD-ROM drive at the base address specified in aztcd.h at compile time. This
80address can be overwritten by boot parameter aztcd=....You should reboot and
81start Linux with boot parameter aztcd=<base address>, e.g. aztcd=0x320. If
82you do not know the base address, start your PC with DOS and look at the boot
83message of your CD-ROM's DOS driver. If that still does not help, use boot
84parameter aztcd=<base address>,0x79 , this tells aztcd to try a little harder.
85aztcd may be configured to use autoprobing the base address by recompiling
86it (see chapter 4.).
87
88If the message looks correct, as user 'root' you should be able to mount the
89drive by
90 mount -t iso9660 -r /dev/aztcd0 /mnt
91and 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
96If you still get a different message while Linux boots or when you get the
97message, that the ISO9660-filesystem is not supported by your kernel, when
98you try to mount the CD-ROM drive, you have to recompile your kernel.
99
100If you do *not* have an Aztech/Orchid/Okano/Wearnes/TXC drive and want to
101bypass drive detection during Linux boot up, start with boot parameter aztcd=0.
102
103Most distributions nowadays do contain a boot disk image containing aztcd.
104Please note, that this driver will not work with IDE/ATAPI drives! With these
105you must use ide-cd.c instead.
106
1074. RECOMPILING YOUR KERNEL
108If your kernel is not yet configured for the AZTECH driver and the ISO9660-
109filesystem, 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
1514.1 AZTCD AS A RUN-TIME LOADABLE MODULE
152If you do not need aztcd permanently, you can also load and remove the driver
153during runtime via insmod and rmmod. To build aztcd as a loadable module you
154must configure your kernel for AZTECH module support (answer 'm' when con-
155figuring the kernel). Anyhow, you may run into problems, if the version of
156your boot kernel is not the same than the source kernel version, from which
157you create the modules. So rebuild your kernel, if necessary.
158
159Now edit the base address of your AZTECH interface card in
160/usr/src/linux/drivers/cdrom/aztcd.h to the appropriate value.
161aztcd may be configured to use autoprobing the base address by setting
162AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed
163under AZT_BASE_AUTO. But please remember, that autoprobing always may
164incorrectly influence other hardware components too!
165There are also some special features which may be configured, e.g.
166auto-eject a CD when unmounting the drive etc; see aztcd.h for details.
167Then change to /usr/src/linux and do a
168 make modules
169 make modules_install
170After that you can run-time load the driver via
171 insmod /lib/modules/X.X.X/misc/aztcd.o
172and remove it via rmmod aztcd.
173If you did not set the correct base address in aztcd.h, you can also supply the
174base address when loading the driver via
175 insmod /lib/modules/X.X.X/misc/aztcd.o aztcd=<base address>
176Again specifying aztcd=-1 will cause autoprobing.
177If you do not have the iso9660-filesystem in your boot kernel, you also have
178to load it before you can mount the CDROM:
179 insmod /lib/modules/X.X.X/fs/isofs.o
180The mount procedure works as described in 4. above.
181(In all commands 'X.X.X' is the current linux kernel version number)
182
1834.2 CDROM CONNECTED TO A SOUNDCARD
184Most soundcards do have a bus interface to the CDROM-drive. In many cases
185this soundcard needs to be configured, before the CDROM can be used. This
186configuration procedure consists of writing some kind of initialization
187data to the soundcard registers. The AZTECH-CDROM driver in the moment does
188only support one type of soundcard (SoundWave32). Users of other soundcards
189should try to boot DOS first and let their DOS drivers initialize the
190soundcard and CDROM, then warm boot (or use loadlin) their PC to start
191Linux.
192Support for the CDROM-interface of SoundWave32-soundcards is directly
193implemented in the AZTECH driver. Please edit linux/drivers/cdrom/aztdc.h,
194uncomment line '#define AZT_SW32' and set the appropriate value for
195AZT_BASE_ADDR and AZT_SW32_BASE_ADDR. This support was tested with an Orchid
196CDS-3110 connected to a SoundWave32.
197If you want your soundcard to be supported, find out, how it needs to be
198configured and mail me (see 6.) the appropriate information.
199
2005. KNOWN PROBLEMS, FUTURE DEVELOPMENTS
2015.1 MULTISESSION SUPPORT
202Multisession support for CD's still is a myth. I implemented and tested a basic
203support for multisession and XA CDs, but I still have not enough CDs and appli-
204cations 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
206multisession support in aztcd.h by setting AZT_MULTISESSION to 1. Doing so
207will cause the ISO9660-filesystem to deal with multisession CDs, ie. redirect
208requests to the Table of Contents (TOC) information from the last session,
209which contains the info of all previous sessions etc.. If you do set
210AZT_MULTISESSION to 0, you can use multisession CDs anyway. In that case the
211drive's firmware will do automatic redirection. For the ISO9660-filesystem any
212multisession CD will then look like a 'normal' single session CD. But never-
213theless the data of all sessions are viewable and accessible. So with practical-
214ly all real world applications you won't notice the difference. But as future
215applications may make use of advanced multisession features, I've started to
216implement the interface for the ISO9660 multisession interface via ioctl
217CDROMMULTISESSION.
218
2195.2 STATUS RECOGNITION
220The drive status recognition does not work correctly in all cases. Changing
221a disk or having the door open, when a drive is already mounted, is detected
222by the Aztech driver itself, but nevertheless causes multiple read attempts
223by the different layers of the ISO9660-filesystem driver, which finally timeout,
224so you have to wait quite a little... But isn't it bad style to change a disk
225in a mounted drive, anyhow ?!
226
227The driver uses busy wait in most cases for the drive handshake (macros
228STEN_LOW and DTEN_LOW). I tested with a 486/DX2 at 66MHz and a Pentium at
22960MHz and 90MHz. Whenever you use a much faster machine you are likely to get
230timeout messages. In that case edit aztcd.h and increase the timeout value
231AZT_TIMEOUT.
232
233For 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
235aztcd.h and increase the timeout value AZT_STATUS_DELAY. The waitqueue has
236shown to be a little critical. If you get kernel panic messages, edit aztcd.c
237and substitute STEN_LOW_WAIT by STEN_LOW. Busy waiting with STEN_LOW is more
238stable, but also causes CPU overhead.
239
2405.3 DOSEMU's CD-ROM SUPPORT
241With release 1.20 aztcd was modified to allow access to CD-ROMS when running
242under dosemu-0.60.0 aztcd-versions before 1.20 are most likely to crash
243Linux, when a CD-ROM is accessed under dosemu. This problem has partly been
244fixed, but still when accessing a directory for the first time the system
245might hang for some 30sec. So be patient, when using dosemu's CD-ROM support
246in combination with aztcd :-) !
247This problem has now (July 1995) been fixed by a modification to dosemu's
248CD-ROM driver. The new version came with dosemu-0.60.2, see dosemu's
249README.CDROM.
250
2516. BUG REPORTS
252Please send detailed bug reports and bug fixes via EMail to
253
254 Werner.Zimmermann@fht-esslingen.de
255
256Please include a description of your CD-ROM drive type and interface card,
257the exact firmware message during Linux bootup, the version number of the
258AZTECH-CDROM-driver and the Linux kernel version. Also a description of your
259system's other hardware could be of interest, especially microprocessor type,
260clock frequency, other interface cards such as soundcards, ethernet adapter,
261game cards etc..
262
263I will try to collect the reports and make the necessary modifications from
264time to time. I may also come back to you directly with some bug fixes and
265ask you to do further testing and debugging.
266
267Editors of CD-ROMs are invited to send a 'cooperation' copy of their
268CD-ROMs to the volunteers, who provided the CD-ROM support for Linux. My
269snail mail address for such 'stuff' is

2787. OTHER DRIVES
279The following drives ORCHID CDS3110, OKANO CDD110, WEARNES CDD110 and Conrad
280TXC Nr. 993123-series 04 nearly look the same as AZTECH CDA268-01A, especially
281they seem to use the same command codes. So it was quite simple to make the
282AZTECH driver work with these drives.
283
284Unfortunately I do not have any of these drives available, so I couldn't test
285it myself. In some installations, it seems necessary to initialize the drive
286with the DOS driver before (especially if combined with a sound card) and then
287do a warm boot (CTRL-ALT-RESET) or start Linux from DOS, e.g. with 'loadlin'.
288
289If you do not succeed, read chapter DEBUGGING. Thanks in advance!
290
291Sorry for the inconvenience, but it is difficult to develop for hardware,
292which you don't have available for testing. So if you like, please help us.
293
294If you do have a CyCDROM CR520ie thanks to Hilmar Berger's help your chances
295are good, that it will work with aztcd. The CR520ie is sold as an IDE-drive
296and really is connected to the IDE interface (primary at 0x1F0 or secondary
297at 0x170, configured as slave, not as master). Nevertheless it is not ATAPI
298compatible but still uses Aztech's command codes.
299
300
3018. 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
331If 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
339If you see STEN_LOW or STEN_LOW_WAIT error messages, increase the timeout
340values.
341
342If 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
382If you still don't succeed, a good point to start is to look in aztcd.c in
383function aztcd_init, where the drive should be detected during init. Do the
384following:
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
402If you succeed, please mail me the exact version string of your drive and
403the code modifications, you have made together with a short explanation.
404If you don't succeed, you may mail me the output of the debugging messages.
405But remember, they are only useful, if they are exact and complete and you
406describe in detail your hardware setup and what you did (cold/warm reboot,
407with/without DOS, DOS-driver started/not started, which Linux-commands etc.)

4109. TECHNICAL HISTORY OF THE DRIVER
411The AZTECH-Driver is a rework of the Mitsumi-Driver. Four major items had to
412be reworked:
413
414a) The Mitsumi drive does issue complete status information acknowledging
415each command, the Aztech drive does only signal that the command was
416processed. So whenever the complete status information is needed, an extra
417ACMD_GET_STATUS command is issued. The handshake procedure for the drive
418can be found in the functions aztSendCmd(), sendAztCmd() and getAztStatus().
419
420b) The Aztech Drive does not have a ACMD_GET_DISK_INFO command, so the
421necessary info about the number of tracks (firstTrack, lastTrack), disk
422length etc. has to be read from the TOC in the lead in track (see function
423aztGetDiskInfo()).
424
425c) Whenever data is read from the drive, the Mitsumi drive is started with a
426command to read an indefinite (0xffffff) number of sectors. When the appropriate
427number of sectors is read, the drive is stopped by a ACDM_STOP command. This
428does not work with the Aztech drive. I did not find a way to stop it. The
429stop and pause commands do only work in AUDIO mode but not in DATA mode.
430Therefore I had to modify the 'finite state machine' in function azt_poll to
431only read a certain number of sectors and then start a new read on demand. As I
432have not completely understood, how the buffer/caching scheme of the Mitsumi
433driver was implemented, I am not sure, if I have covered all cases correctly,
434whenever you get timeout messages, the bug is most likely to be in that
435function azt_poll() around switch(cmd) .... case ACD_S_DATA.
436
437d) I did not get information about changing drive mode. So I doubt, that the
438code around function azt_poll() case AZT_S_MODE does work. In my test I have
439not been able to switch to reading in raw mode. For reading raw mode, Aztech
440uses a different command than for cooked mode, which I only have implemen-
441ted in the ioctl-section but not in the section which is used by the ISO9660.
442
443The driver was developed on an AST PC with Intel 486/DX2, 8MB RAM, 340MB IDE
444hard disk and on an AST PC with Intel Pentium 60MHz, 16MB RAM, 520MB IDE
445running Linux kernel version 1.0.9 from the LST 1.8 Distribution. The kernel
446was compiled with gcc.2.5.8. My CD-ROM drive is an Aztech CDA268-01A. My
447drive says, that it has Firmware Version AZT26801A1.3. It came with an ISA-bus
448interface card and works with polled I/O without DMA and without interrupts.
449The code for all other drives was 'remote' tested and debugged by a number of
450volunteers on the Internet.
451
452Points, where I feel that possible problems might be and all points where I
453did not completely understand the drive's behaviour or trust my own code are
454marked with /*???*/ in the source code. There are also some parts in the
455Mitsumi driver, where I did not completely understand their code.

45810. ACKNOWLEDGMENTS
459Without the help of P.Bush, Aztech, who delivered technical information
460about the Aztech Drive and without the help of E.Moenkeberg, GWDG, who did a
461great job in analyzing the command structure of various CD-ROM drives, this
462work would not have been possible. E.Moenkeberg was also a great help in
463making the software 'kernel ready' and in answering many of the CDROM-related
464questions in the newsgroups. He really is *the* Linux CD-ROM guru. Thanks
465also to all the guys on the Internet, who collected valuable technical
466information about CDROMs.
467
468Joe Nardone (joe@access.digex.net) was a patient tester even for my first
469trial, which was more than slow, and made suggestions for code improvement.
470Especially the 'finite state machine' azt_poll() was rewritten by Joe to get
471clean C code and avoid the ugly 'gotos', which I copied from mcd.c.
472
473Robby Schirmer (schirmer@fmi.uni-passau.de) tested the audio stuff (ioctls)
474and suggested a lot of patches for them.
475
476Joseph Piskor and Peter Nugent were the first users with the ORCHID CD3110
477and also were very patient with the problems which occurred.
478
479Reinhard Max delivered the information for the CDROM-interface of the
480SoundWave32 soundcards.
481
482Jochen Kunz and Olaf Kaluza delivered the information for supporting Conrad's
483TXC drive.
484
485Hilmar Berger delivered the patches for supporting CyCDROM CR520ie.
486
487Anybody, who is interested in these items should have a look at 'ftp.gwdg.de',
488directory 'pub/linux/cdrom' and at 'ftp.cdrom.com', directory 'pub/cdrom'.
489
49011. PROGRAMMING ADD ONs: cdplay.c
491You can use the ioctl-functions included in aztcd.c in your own programs. As
492an example on how to do this, you will find a tiny CD Player for audio CDs
493named 'cdplay.c'. It allows you to play audio CDs. You can play a specified
494track, pause and resume or skip tracks forward and backwards. If you quit the
495program 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
497APPENDIX of this file, which you should cut out with an editor and store in a
498separate 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
506You 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
508mounted, when you're playing audio CDs.
509
510This program is just a hack for testing the ioctl-functions in aztcd.c. I will
511not maintain it, so if you run into problems, discard it or have a look into
512the source code 'cdplay.c'. The program does only contain a minimum of user
513protection and input error detection. If you use the commands in the wrong
514order or if you try to read a CD at wrong addresses, you may get error messages
515or even hang your machine. If you get STEN_LOW, STEN_LOW_WAIT or segment violation
516error messages when using cdplay, after that, the system might not be stable
517any more, so you'd better reboot. As the ioctl-functions run in kernel mode,
518most normal Linux-multitasking protection features do not work. By using
519uninitialized 'wild' pointers etc., it is easy to write to other users' data
520and program areas, destroy kernel tables etc.. So if you experiment with ioctls
521as always when you are doing systems programming and kernel hacking, you
522should have a backup copy of your system in a safe place (and you also
523should try restoring from a backup copy first)!
524
525A reworked and improved version called 'cdtester.c', which has yet more
526features for testing CDROM-drives can be found in
527Documentation/cdrom/sbpcd, written by E.Moenkeberg.

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

77 0x320 Short Short
78 0x330 Short Open
79 0x340 Open Short
80 0x360 Open Open

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
102Note that if you have another interface card, you will need to look at
103the documentation to find the I/O base address. This is specified to
104the SLCD.SYS driver for DOS with the /B: parameter, so you can look at
105you DOS driver setup to find the address, if necessary.
106
107Configuring the Kernel
108----------------------
109
110You must tell the kernel where the drive is at boot time. This can be
111done at the Linux boot prompt, by using LILO, or by using Bootlin.
112Note that this is no substitute for HOWTOs and LILO documentation, if
113you are confused please read those for info on bootline configuration
114and LILO.
115
116At the linux boot prompt, press the ALT key and add the following line
117after the boot name (you can let the kernel boot, it will tell you the
118default boot name while booting):
119
120 cdu31a=<base address>,<interrupt>[,PAS]
121
122The base address needs to have "0x" in front of it, since it is in
123hex. For instance, to configure a drive at address 320 on interrupt 5,
124use the following:
125
126 cdu31a=0x320,5
127
128I use the following boot line:
129
130 cdu31a=0x1f88,0,PAS
131
132because I have a PAS-16 which does not support interrupt for the
133CDU31A interface.
134
135Adding this as an append line at the beginning of the /etc/lilo.conf
136file will set it for lilo configurations. I have the following as the
137first line in my lilo.conf file:
138
139 append="cdu31a=0x1f88,0"
140
141I'm not sure how to set up Bootlin (I have never used it), if someone
142would like to fill in this section please do.
143
144
145Configuring as a Module
146-----------------------
147
148The driver supports loading as a module. However, you must specify
149the boot address and interrupt on the boot line to insmod. You can't
150use modprobe to load it, since modprobe doesn't support setting
151variables.
152
153Anyway, 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
157You 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
166Driver Special Features
167-----------------------
168
169This section describes features beyond the normal audio and CD-ROM
170functions of the drive.
171
1722048 byte buffer mode
173
174If a disk is mounted with -o block=2048, data is copied straight from
175the drive data port to the buffer. Otherwise, the readahead buffer
176must be involved to hold the other 1K of data when a 1K block
177operation is done. Note that with 2048 byte blocks you cannot execute
178files from the CD.
179
180XA compatibility
181
182The driver should support XA disks for both the CDU31A and CDU33A. It
183does this transparently, the using program doesn't need to set it.
184
185Multi-Session
186
187A multi-session disk looks just like a normal disk to the user. Just
188mount one normally, and all the data should be there. A special
189thanks to Koen for help with this!
190
191Raw sector I/O
192
193Using the CDROMREADAUDIO it is possible to read raw audio and data
194tracks. Both operations return 2352 bytes per sector. On the data
195tracks, the first 12 bytes is not returned by the drive and the value
196of that data is indeterminate.

1This is the readme file for the driver for the Philips/LMS cdrom drive
2cm206 in combination with the cm260 host adapter card.
3
4 (c) 1995 David A. van Leeuwen
5
6Changes 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
12Features 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
19Features 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
31Decide how you are going to use the driver. There are two
32options:
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
45Compiling the kernel
46--------------------
471) 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
572) then do a
58
59 make clean; make zImage; make modules
60
613) 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
65Using the driver as a module
66----------------------------
67If you will only occasionally use the cd-rom driver, you can choose
68option (b), install as a loadable module. You may have to re-compile
69the module when you upgrade the kernel to a new version.
70
71Since version 0.96, much of the functionality has been transferred to
72a generic cdrom interface in the file cdrom.c. The module cm206.o
73depends on cdrom.o. If the latter is not compiled into the kernel,
74you must explicitly load it before cm206.o:
75
76 insmod /usr/src/linux/modules/cdrom.o
77
78To install the module, you use the command, as root
79
80 insmod /usr/src/linux/modules/cm206.o
81
82You can specify the base address on the command line as well as the irq
83line to be used, e.g.
84
85 insmod /usr/src/linux/modules/cm206.o cm206=0x300,11
86
87The order of base port and irq line doesn't matter; if you specify only
88one, the other will have the value of the compiled-in default. You
89may also have to install the file-system module `iso9660.o', if you
90didn't compile that into the kernel.
91
92
93Using the driver as part of the kernel
94--------------------------------------
95If you have chosen option (a), you can specify the base-port
96address and irq on the lilo boot command line, e.g.:
97
98 LILO: linux cm206=0x340,11
99
100This assumes that your linux kernel image keyword is `linux'.
101If you specify either IRQ (3--11) or base port (0x300--0x370),
102auto probing is turned off for both settings, thus setting the
103other value to the compiled-in default.
104
105Note that you can also put these parameters in the lilo configuration file:
106
107# linux config
108image = /vmlinuz
109 root = /dev/hda1
110 label = Linux
111 append = "cm206=0x340,11"
112 read-only
113
114
115If module parameters and LILO config options don't work
116-------------------------------------------------------
117If autoprobing does not work, you can hard-wire the default values
118of the base port address (CM206_BASE) and interrupt request line
119(CM206_IRQ) into the file /usr/src/linux/drivers/cdrom/cm206.h. Change
120the defines of CM206_IRQ and CM206_BASE.
121
122
123Mounting the cdrom
124------------------
1251) Make sure that the right device is installed in /dev.
126
127 mknod /dev/cm206cd b 32 0
128
1292) Make sure there is a mount point, e.g., /cdrom
130
131 mkdir /cdrom
132
1333) mount using a command like this (run as root):
134
135 mount -rt iso9660 /dev/cm206cd /cdrom
136
1374) 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
146If 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.
154
155- Look in the /proc directory to see if `cm206' shows up under one of
156 `interrupts', `ioports', `devices' or `modules' (if applicable).
157
158
159DISCLAIMER
160----------
161I cannot guarantee that this driver works, or that the hardware will
162not be harmed, although I consider it most unlikely.
163
164I hope that you'll find this driver in some way useful.

169Note for Linux CDROM vendors
170-----------------------------
171You are encouraged to include this driver on your Linux CDROM. If
172you do, you might consider sending me a free copy of that cd-rom.
173You can contact me through my e-mail address, david@tm.tno.nl.
174If this driver is compiled into a kernel to boot off a cdrom,
175you should actually send me a free copy of that cd-rom.

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
14This current driver version 0.4a only supports reading data from the disk.
15Currently we have no audio and no multisession or XA support.
16The polling interface is used, no DMA.
17
18
19Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's
20drive interface is compatible, too.
21
22
23Installation
24------------
25
26Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert
27the i/o address of your interface card.
28
29The default base address is 0x340. This will work for most applications.
30Address selection is accomplished by jumpers PN801-1 to PN801-4 on the
31GoldStar Interface Card.
32Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360
330x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0
34
35Then go back to '/usr/src/linux/' and 'make config' to build the new
36configuration for your kernel. If you want to use the GoldStar driver
37like a module, don't select 'GoldStar CDROM support'. By the way, you
38have to include the iso9660 filesystem.
39
40Now start compiling the kernel with 'make zImage'.
41If you want to use the driver as a module, you have to do 'make modules'
42and 'make modules_install', additionally.
43Install your new kernel as usual - maybe you do it with 'make zlilo'.
44
45Before you can use the driver, you have to
46 mknod /dev/gscd0 b 16 0
47to create the appropriate device file (you only need to do this once).
48
49If you use modules, you can try to insert the driver.
50Say: 'insmod /usr/src/linux/modules/gscd.o'
51or: 'insmod /usr/src/linux/modules/gscd.o gscd=<address>'
52The driver should report its results.
53
54That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom'
55
56Feel free to report errors and suggestions to the following address.
57Be sure, I'm very happy to receive your comments!

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

1This is the README file for the Optics Storage 8000 AT CDROM device driver.
2
3This is the driver for the so-called 'DOLPHIN' drive, with the 34-pin
4Sony-compatible interface. For the IDE-compatible Optics Storage 8001
5drive, you will want the ATAPI CDROM driver. The driver also seems to
6work with the Lasermate CR328A. If you have a drive that works with
7this driver, and that doesn't report itself as DOLPHIN, please drop me
8a mail.
9
10The support for multisession CDs is in ALPHA stage. If you use it,
11please mail me your experiences. Multisession support can be disabled
12at compile time.
13
14You can find some older versions of the driver at
15 dutette.et.tudelft.nl:/pub/linux/
16and at Eberhard's mirror
17 ftp.gwdg.de:/pub/linux/cdrom/drivers/optics/
18
19Before you can use the driver, you have to create the device file once:
20 # mknod /dev/optcd0 b 17 0
21
22To specify the base address if the driver is "compiled-in" to your kernel,
23you can use the kernel command line item (LILO option)
24 optcd=0x340
25with the right address.
26
27If you have compiled optcd as a module, you can load it with
28 # insmod /usr/src/linux/modules/optcd.o
29or
30 # insmod /usr/src/linux/modules/optcd.o optcd=0x340
31with the matching address value of your interface card.
32
33The driver employs a number of buffers to do read-ahead and block size
34conversion. The number of buffers is configurable in optcd.h, and has
35influence on the driver performance. For my machine (a P75), 6 buffers
36seems optimal, as can be seen from this table:
37
38#bufs kb/s %cpu
391 97 0.1
402 191 0.3
413 188 0.2
424 246 0.3
435 189 19
446 280 0.4
457 281 7.0
468 246 2.8
4716 281 3.4
48
49If you get a throughput significantly below 300 kb/s, try tweaking
50N_BUFS, and don't forget to mail me your results!
51
52I'd appreciate success/failure reports. If you find a bug, try
53recompiling the driver with some strategically chosen debug options
54(these can be found in optcd.h) and include the messages generated in
55your bug report. Good luck.

1This README belongs to release 4.2 or newer of the SoundBlaster Pro
2(Matsushita, Kotobuki, Panasonic, CreativeLabs, Longshine and Teac)
3CD-ROM driver for Linux.
4
5sbpcd really, really is NOT for ANY IDE/ATAPI drive!
6Not even if you have an "original" SoundBlaster card with an IDE interface!
7So, you'd better have a look into README.ide if your port address is 0x1F0,
80x170, 0x1E8, 0x168 or similar.
9I get tons of mails from IDE/ATAPI drive users - I really can't continue
10any more to answer them all. So, if your drive/interface information sheets
11mention "IDE" (primary, secondary, tertiary, quaternary) and the DOS driver
12invoking line within your CONFIG.SYS is using an address below 0x230:
13DON'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
15use ide-cd as your driver. If you do not have a second IDE hard disk, use the
16LILO commands
17 hdb=noprobe hdc=cdrom
18and get lucky.
19To make it fully clear to you: if you mail me about IDE/ATAPI drive problems,
20my answer is above, and I simply will discard your mail, hoping to stop the
21flood and to find time to lead my 12-year old son towards happy computing.
22
23The driver is able to drive the whole family of "traditional" AT-style (that
24is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita,
25Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The
26well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563.
27CR-574 is an IDE/ATAPI drive.
28
29The Longshine LCS-7260 is a double-speed drive which uses the "old"
30Matsushita command set. It is supported - with help by Serge Robyns.
31Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support
32has started; get in contact if you have such a "Vertos 100" or "ECS-AT"
33drive.
34
35There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563
36with a special controller board. This drive is supported (the interface is
37of the "LaserMate" type), and it is possibly the best buy today (cheaper than
38an internal drive, and you can use it as an internal, too - e.g. plug it into
39a soundcard).
40
41CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter
42is made by Funai and sometimes named "E2550UA", newer models may be named
43"MK4015". The CD200F drives should fully work.
44CD200 drives without "F" are still giving problems: drive detection and
45playing audio should work, data access will result in errors. I need qualified
46feedback about the bugs within the data functions or a drive (I never saw a
47CD200).
48
49The quad-speed Teac CD-55A drive is supported, but still does not reach "full
50speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES
51to 64 (it is not recommended to do that for normal "file access" usage, but it
52can speed up things a lot if you use something like "dd" to read from the
53drive; I use it for verifying self-written CDs this way).
54The drive itself is able to deliver 600 kB/sec, so this needs
55work; with the normal setup, the performance currently is not even as good as
56double-speed.
57
58This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives,
59and again: this driver is in no way usable for any IDE/ATAPI drive. If you
60think your drive should work and it doesn't: send me the DOS driver for your
61beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help,
62and include an original log message excerpt, and try to give all information
63a complete idiot needs to understand your hassle already with your first
64mail. And if you want to say "as I have mailed you before", be sure that I
65don't remember your "case" by such remarks; at the moment, I have some
66hundreds of open correspondences about Linux CDROM questions (hope to reduce if
67the IDE/ATAPI user questions disappear).
68
69
70This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy,
71SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P,
72LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...).
73
74It works with the "configurable" interface "Sequoia S-1000", too, which is
75used on the Spea Media FX and Ensonic Soundscape sound cards. You have to
76specify the type "SBPRO 2" and the true CDROM port address with it, not the
77"configuration port" address.
78
79If you have a sound card which needs a "configuration driver" instead of
80jumpers for interface types and addresses (like Mozart cards) - those
81drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical
82names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the
83CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c
84are just for you!). Hannu Savolainen's mad16.c code is able to set up my
85Mozart card - I simply had to add
86 #define MAD16_CONF 0x06
87 #define MAD16_CDSEL 0x03
88to configure the CDROM interface for type "Panasonic" (LaserMate) and address
890x340.
90
91The interface type has to get configured in linux/drivers/cdrom/sbpcd.h,
92because the register layout is different between the "SoundBlaster" and the
93"LaserMate" type.
94
95I 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
970x300 and above. This is unusual, and it can't get covered by the auto
98probing scheme.
99The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0)
100need the SBPRO 3 setup.
101
102If auto-probing found the drive, the address is correct. The reported type
103may be wrong. A "mount" will give success only if the interface type is set
104right. Playing audio should work with a wrong set interface type, too.
105
106With some Teac and some CD200 drives I have seen interface cards which seem
107to 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
109interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if
110possible).
111
112
113Up to 4 drives per interface card, and up to 4 interface cards are supported.
114All supported drive families can be mixed, but the CR-521 drives are
115hard-wired to drive ID 0. The drives have to use different drive IDs, and each
116drive has to get a unique minor number (0...3), corresponding indirectly to
117its drive ID.
118The drive IDs may be selected freely from 0 to 3 - they do not have to be in
119consecutive order.
120
121As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible
122to 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
138To use more than 4 drives, you simply need a second controller card at a
139different address and a second cable.
140
141The driver supports reading of data from the CD and playing of audio tracks.
142The audio part should run with WorkMan, xcdplayer, with the "non-X11" products
143CDplayer and WorkBone - tell me if it is not compatible with other software.
144The only accepted measure for correctness with the audio functions is the
145"cdtester" utility (appended) - most audio player programmers seem to be
146better musicians than programmers. ;-)
147
148With the CR-56x and the CD200 drives, the reading of audio frames is possible.
149This is implemented by an IOCTL function which reads READ_AUDIO frames of
1502352 bytes at once (configurable with the "READ_AUDIO" define, default is 0).
151Reading the same frame a second time gives different data; the frame data
152start at a different position, but all read bytes are valid, and we always
153read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame
154at once possibly misses some chunks at each frame boundary. This lack has to
155get corrected by external, "higher level" software which reads the same frame
156again and tries to find and eliminate overlapping chunks (24-byte-pieces).
157
158The transfer rate with reading audio (1-frame-pieces) currently is very slow.
159This can be better reading bigger chunks, but the "missing" chunks possibly
160occur at the beginning of each single frame.
161The software interface possibly may change a bit the day the SCSI driver
162supports it too.
163
164With all but the CR-52x drives, MultiSession is supported.
165Photo CDs work (the "old" drives like CR-521 can access only the first
166session of a photoCD).
167At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to
168convert photo CD image files and Gerd Knorr's viewing utility.
169
170The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with
171CR-56x drives, and currently not more than 500 kB/sec (usually less than
172250 kB/sec) with the Teac quad speed drives.
173XA (PhotoCD) disks with "old" drives give only 50 kB/sec.
174
175This 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
182To install:
183-----------
184
1851. 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
2272. "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
2323. Then make the kernel image ("make zlilo" or similar).
233
2344. 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
2575. Reboot with the new kernel.
258
259You should now be able to do
260 mkdir /CD
261and
262 mount -rt iso9660 /dev/sbpcd /CD
263or
264 mount -rt iso9660 -o block=2048 /dev/sbpcd /CD
265and see the contents of your CD in the /CD directory.
266To use audio CDs, a mounting is not recommended (and it would fail if the
267first track is not a data track).
268
269
270Using sbpcd as a "loadable module":
271-----------------------------------
272
273If 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
276If sbpcd gets used as a module, the support of more than one interface
277card (i.e. drives 4...15) is disabled.
278
279You can specify interface address and type with the "insmod" command like:
280 # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0
281or
282 # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1
283or
284 # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2
285where the last number represents the SBPRO setting (no strings allowed here).
286
287
288Things of interest:
289-------------------
290
291The driver is configured to try the LaserMate type of interface at I/O port
2920x0340 first. If this is not appropriate, sbpcd.h should get changed
293(you will find the right place - just at the beginning).
294
295No DMA and no IRQ is used.
296
297To reduce or increase the amount of kernel messages, edit sbpcd.c and play
298with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug").
299Don't forget to reflect on what you do; enabling all DBG_xxx switches at once
300may crash your system, and each message line is accompanied by a delay.
301
302The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to
303specify "block=2048" as a mount option. Doing this will disable the direct
304execution of a binary from the CD; you have to copy it to a device with the
305standard BLOCK_SIZE (1024) first. So, do not use this if your system is
306directly "running from the CDROM" (like some of Yggdrasil's installation
307variants). There are CDs on the market (like the German "unifix" Linux
308distribution) which MUST get handled with a block_size of 1024. Generally,
309one can say all the CDs which hold files of the name YMTRANS.TBL are defective;
310do not use block=2048 with those.
311
312Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With
313these, you can configure the driver for some special things.
314You can use the appended program "cdtester" to set the auto-eject feature
315during runtime. Jeff Tranter's "eject" utility can do this, too (and more)
316for you.
317
318There is an ioctl CDROMMULTISESSION to obtain with a user program if
319the 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
323Auto-probing at boot time:
324--------------------------
325
326The driver does auto-probing at many well-known interface card addresses,
327but not all:
328Some probings can cause a hang if an NE2000 ethernet card gets touched, because
329SBPCD's auto-probing happens before the initialization of the net drivers.
330Those "hazardous" addresses are excluded from auto-probing; the "kernel
331command line" feature has to be used during installation if you have your
332drive at those addresses. The "module" version is allowed to probe at those
333addresses, too.
334
335The auto-probing looks first at the configured address resp. the address
336submitted by the kernel command line. With this, it is possible to use this
337driver within installation boot floppies, and for any non-standard address,
338too.
339
340Auto-probing will make an assumption about the interface type ("SBPRO" or not),
341based upon the address. That assumption may be wrong (initialization will be
342o.k., but you will get I/O errors during mount). In that case, use the "kernel
343command line" feature and specify address & type at boot time to find out the
344right setup.
345
346For everyday use, address and type should get configured within sbpcd.h. That
347will stop the auto-probing due to success with the first try.
348
349The kernel command "sbpcd=0" suppresses each auto-probing and causes
350the driver not to find any drive; it is meant for people who love sbpcd
351so much that they do not want to miss it, even if they miss the drives. ;-)
352
353If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is
354initially disabled and needs an explicit kernel command to get activated.
355Once activated, it does not stop before success or end-of-list. This may be
356useful within "universal" CDROM installation boot floppies (but using the
357loadable module would be better because it allows an "extended" auto-probing
358without fearing NE2000 cards).
359
360To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within
361sbpcd.h.
362
363
364Setting up address and interface type:
365--------------------------------------
366
367If your I/O port address is not 0x340, you have to look for the #defines near
368the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and
369change CDROM_PORT to the address of your CDROM I/O port.
370
371Almost all of the "SoundBlaster compatible" cards behave like the no-sound
372interfaces, i.e. need SBPRO 0!
373
374With "original" SB Pro cards, an initial setting of CD_volume through the
375sound card's MIXER register gets done.
376If you are using a "compatible" sound card of types "LaserMate" or "SPEA",
377you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too...
378

380Using audio CDs:
381----------------
382
383Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see
384README.aztcd from the Aztech driver package) should work.
385
386The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants
387"/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the
388appropriate links to use them without the need to supply parameters.
389
390
391Copying audio tracks:
392---------------------
393
394The following program will copy track 1 (or a piece of it) from an audio CD
395into 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!

524At ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz is an adapted version of
525Heiko Eissfeldt's digital-audio to .WAV converter (the original is there, too).
526This is preliminary, as Heiko himself will care about it.

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

9This is the README for the sjcd cdrom driver, version 1.6.
10
11This file is meant as a tips & tricks edge for the usage of the SANYO CDR-H94A
12cdrom drive. It will grow as the questions arise. ;-)
13For info on configuring the ISP16 sound card look at Documentation/cdrom/isp16.
14
15The driver should work with any of the Panasonic, Sony or Mitsumi style
16CDROM interfaces.
17The cdrom interface on Media Magic's soft configurable sound card ISP16,
18which used to be included in the driver, is now supported in a separate module.
19This initialisation module will probably also work with other interfaces
20based on an OPTi 82C928 or 82C929 chip (like MAD16 and Mozart): see the
21documentation Documentation/cdrom/isp16.
22
23The device major for sjcd is 18, and minor is 0. Create a block special
24file 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
26the trick:
27 mknod -m 644 /dev/sjcd b 18 0
28and mount the cdrom by /dev/sjcd).
29
30The 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.)
35As of version 1.2, setting base address at boot time is supported
36through 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
39file /etc/lilo.conf). You could also use 'append="sjcd=<configuration_info>"'
40in the appropriate section of /etc/lilo.conf
41If you're building a kernel yourself you can set your default base
42i/o address with SJCD_BASE_ADDR in /usr/src/linux/drivers/cdrom/sjcd.h.
43
44The sjcd driver supports being loaded as a module. The following
45command will set the base i/o address on the fly (assuming you
46have 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
4This is the Sony CDU-535 (and 531) driver version 0.7 for Linux.
5I do not think I have the documentation to add features like DMA support
6so 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
8steal some of that code.)
9
10This is a Linux device driver for the Sony CDU-535 CDROM drive. This is
11one of the older Sony drives with its own interface card (Sony bus).
12The DOS driver for this drive is named SONY_CDU.SYS - when you boot DOS
13your drive should be identified as a SONY CDU-535. The driver works
14with a CDU-531 also. One user reported that the driver worked on drives
15OEM'ed by Procomm, drive and interface board were labelled Procomm.
16
17The Linux driver is based on Corey Minyard's sonycd 0.3 driver for
18the CDU-31A. Ron Jeppesen just changed the commands that were sent
19to the drive to correspond to the CDU-535 commands and registers.
20There were enough changes to let bugs creep in but it seems to be stable.
21Ron was able to tar an entire CDROM (should read all blocks) and built
22ghostview and xfig off Walnut Creek's X11R5/GNU CDROM. xcdplayer and
23workman work with the driver. Others have used the driver without
24problems except those dealing with wait loops (fixed in third release).
25Like Minyard's original driver this one uses a polled interface (this
26is also the default setup for the DOS driver). It has not been tried
27with interrupts or DMA enabled on the board.
28
29REQUIREMENTS
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
44NOTES:
45======
46
471) The drive MUST be turned on when booting or it will not be recognized!
48 (but see comments on modularized version below)
49
502) 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
57THANKS
58======
59
60Many thanks to Ron Jeppesen (ronj.an@site007.saic.com) for getting
61this project off the ground. He wrote the initial release
62and the first two patches to this driver (0.1, 0.2, and 0.3).
63Thanks also to Eberhard Moenkeberg (emoenke@gwdg.de) for prodding
64me 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
66it a better device citizen. Further thanks to Joel Katz
67<joelkatz@webchat.org> for his MODULE patches (see details below),
68Porfiri Claudio <C.Porfiri@nisms.tei.ericsson.se> for patches
69to make the driver work with the older CDU-510/515 series, and
70Heiko Eissfeldt <heiko@colossus.escape.de> for pointing out that
71the 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:)
75Thanks to Corey Minyard who wrote the original CDU-31A driver on which
76this driver is based. Thanks to Ken Pizzini and Bob Blair who provided
77patches 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,
86use the following command:
87
88gcc -c -D__KERNEL__ -DMODULE -O2 sonycd535.c -o sonycd535.o
89
90 To install the module, simply type:
91
92insmod sony535.o
93 or
94insmod sony535.o sonycd535=<address>
95
96 And to remove it:
97
98rmmod sony535
99
100 The code checks to see if MODULE is defined and behaves as it used
101to if MODULE is not defined. That means your patched file should behave
102exactly 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
105to 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
111module) if the CDROM drive is not available during its initialization. This
112means that you can have the driver compiled into the kernel and still load
113the module later (assuming the driver doesn't install itself during
114power-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
117kernel, but load it as a module if I powered the system up with the drive
118off and then later decided to use the CDROM drive.
119
120 Since the driver only uses a single page to point to the chunks,
121attempting to set the buffer cache to more than 2 Megabytes would be very
122bad; don't do that.
