Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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
379
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!

522At ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz is an adapted version of
523Heiko Eissfeldt's digital-audio to .WAV converter (the original is there, too).
524This is preliminary, as Heiko himself will care about it.

527Known problems:
528---------------
529
530Currently, the detection of disk change or removal is actively disabled.
531
532Most attempts to read the UPC/EAN code result in a stream of zeroes. All my
533drives are mostly telling there is no UPC/EAN code on disk or there is, but it
534is an all-zero number. I guess now almost no CD holds such a number.
