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

523 At ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz is an adapted version of
524 Heiko Eissfeldt's digital-audio to .WAV converter (the original is there, too).
525 This is preliminary, as Heiko himself will care about it.
528 Known problems:
529 ---------------
531 Currently, the detection of disk change or removal is actively disabled.
533 Most attempts to read the UPC/EAN code result in a stream of zeroes. All my
534 drives are mostly telling there is no UPC/EAN code on disk or there is, but it
535 is an all-zero number. I guess now almost no CD holds such a number.

538 too :-) etc. to emoenke@gwdg.de.
