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

386 | The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants | |
387 | "/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the | |
388 | appropriate links to use them without the need to supply parameters. | |

391 | Copying audio tracks: | |
392 | --------------------- | |
393 | ||
394 | The following program will copy track 1 (or a piece of it) from an audio CD | |
395 | into the file "track01": | |
396 | ||
397 | /*=================== begin program ========================================*/ | |
398 | /* | |
399 | * read an audio track from a CD | |
400 | * | |
401 | * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de> | |
402 | * may be used & enhanced freely | |
403 | * | |
404 | * Due to non-existent sync bytes at the beginning of each audio frame (or due | |
405 | * to a firmware bug within all known drives?), it is currently a kind of | |
406 | * fortune if two consecutive frames fit together. | |
407 | * Usually, they overlap, or a little piece is missing. This happens in units | |
408 | * of 24-byte chunks. It has to get fixed by higher-level software (reading | |
409 | * until an overlap occurs, and then eliminate the overlapping chunks). | |
410 | * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of | |
411 | * such an algorithm. | |
412 | * This example program further is missing to obtain the SubChannel data | |
413 | * which belong to each frame. | |
414 | * | |
415 | * This is only an example of the low-level access routine. The read data are | |
416 | * pure 16-bit CDDA values; they have to get converted to make sound out of | |
417 | * them. | |
418 | * It is no fun to listen to it without prior overlap/underlap correction! | |

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