- This README belongs to release 4.2 or newer of the SoundBlaster Pro
- (Matsushita, Kotobuki, Panasonic, CreativeLabs, Longshine and Teac)
- CD-ROM driver for Linux.
- sbpcd really, really is NOT for ANY IDE/ATAPI drive!
- Not even if you have an "original" SoundBlaster card with an IDE interface!
- So, you'd better have a look into README.ide if your port address is 0x1F0,
- 0x170, 0x1E8, 0x168 or similar.
- I get tons of mails from IDE/ATAPI drive users - I really can't continue
- any more to answer them all. So, if your drive/interface information sheets
- mention "IDE" (primary, secondary, tertiary, quaternary) and the DOS driver
- invoking line within your CONFIG.SYS is using an address below 0x230:
- DON'T ROB MY LAST NERVE - jumper your interface to address 0x170 and IRQ 15
- (that is the "secondary IDE" configuration), set your drive to "master" and
- use ide-cd as your driver. If you do not have a second IDE hard disk, use the
- LILO commands
- hdb=noprobe hdc=cdrom
- and get lucky.
- To make it fully clear to you: if you mail me about IDE/ATAPI drive problems,
- my answer is above, and I simply will discard your mail, hoping to stop the
- flood and to find time to lead my 12-year old son towards happy computing.
- The driver is able to drive the whole family of "traditional" AT-style (that
- is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita,
- Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The
- well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563.
- CR-574 is an IDE/ATAPI drive.
- The Longshine LCS-7260 is a double-speed drive which uses the "old"
- Matsushita command set. It is supported - with help by Serge Robyns.
- Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support
- has started; get in contact if you have such a "Vertos 100" or "ECS-AT"
- drive.
- There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563
- with a special controller board. This drive is supported (the interface is
- of the "LaserMate" type), and it is possibly the best buy today (cheaper than
- an internal drive, and you can use it as an internal, too - e.g. plug it into
- a soundcard).
- CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter
- is made by Funai and sometimes named "E2550UA", newer models may be named
- "MK4015". The CD200F drives should fully work.
- CD200 drives without "F" are still giving problems: drive detection and
- playing audio should work, data access will result in errors. I need qualified
- feedback about the bugs within the data functions or a drive (I never saw a
- CD200).
- The quad-speed Teac CD-55A drive is supported, but still does not reach "full
- speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES
- to 64 (it is not recommended to do that for normal "file access" usage, but it
- can speed up things a lot if you use something like "dd" to read from the
- drive; I use it for verifying self-written CDs this way).
- The drive itself is able to deliver 600 kB/sec, so this needs
- work; with the normal setup, the performance currently is not even as good as
- double-speed.
- This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives,
- and again: this driver is in no way usable for any IDE/ATAPI drive. If you
- think your drive should work and it doesn't: send me the DOS driver for your
- beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help,
- and include an original log message excerpt, and try to give all information
- a complete idiot needs to understand your hassle already with your first
- mail. And if you want to say "as I have mailed you before", be sure that I
- don't remember your "case" by such remarks; at the moment, I have some
- hundreds of open correspondences about Linux CDROM questions (hope to reduce if
- the IDE/ATAPI user questions disappear).
- This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy,
- SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P,
- LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...).
- It works with the "configurable" interface "Sequoia S-1000", too, which is
- used on the Spea Media FX and Ensonic Soundscape sound cards. You have to
- specify the type "SBPRO 2" and the true CDROM port address with it, not the
- "configuration port" address.
- If you have a sound card which needs a "configuration driver" instead of
- jumpers for interface types and addresses (like Mozart cards) - those
- drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical
- names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the
- CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c
- are just for you!). Hannu Savolainen's mad16.c code is able to set up my
- Mozart card - I simply had to add
- #define MAD16_CONF 0x06
- #define MAD16_CDSEL 0x03
- to configure the CDROM interface for type "Panasonic" (LaserMate) and address
- 0x340.
- The interface type has to get configured in linux/drivers/cdrom/sbpcd.h,
- because the register layout is different between the "SoundBlaster" and the
- "LaserMate" type.
- I got a report that the Teac interface card "I/F E117098" is of type
- "SoundBlaster" (i.e. you have to set SBPRO to 1) even with the addresses
- 0x300 and above. This is unusual, and it can't get covered by the auto
- probing scheme.
- The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0)
- need the SBPRO 3 setup.
- If auto-probing found the drive, the address is correct. The reported type
- may be wrong. A "mount" will give success only if the interface type is set
- right. Playing audio should work with a wrong set interface type, too.
- With some Teac and some CD200 drives I have seen interface cards which seem
- to lack the "drive select" lines; always drive 0 gets addressed. To avoid
- "mirror drives" (four drives detected where you only have one) with such
- interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if
- possible).
- Up to 4 drives per interface card, and up to 4 interface cards are supported.
- All supported drive families can be mixed, but the CR-521 drives are
- hard-wired to drive ID 0. The drives have to use different drive IDs, and each
- drive has to get a unique minor number (0...3), corresponding indirectly to
- its drive ID.
- The drive IDs may be selected freely from 0 to 3 - they do not have to be in
- consecutive order.
- As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible
- to change old drives to any ID, too. He writes in this sense:
- "In order to be able to use more than one single speed drive
- (they do not have the ID jumpers) you must add a DIP switch
- and two resistors. The pads are already on the board next to
- the power connector. You will see the silkscreen for the
- switch if you remove the top cover.
- 1 2 3 4
- ID 0 = x F F x O = "on"
- ID 1 = x O F x F = "off"
- ID 2 = x F O x x = "don't care"
- ID 3 = x O O x
- Next to the switch are the positions for R76 (7k) and R78
- (12k). I had to play around with the resistor values - ID 3
- did not work with other values. If the values are not good,
- ID 3 behaves like ID 0."
- To use more than 4 drives, you simply need a second controller card at a
- different address and a second cable.
- The driver supports reading of data from the CD and playing of audio tracks.
- The audio part should run with WorkMan, xcdplayer, with the "non-X11" products
- CDplayer and WorkBone - tell me if it is not compatible with other software.
- The only accepted measure for correctness with the audio functions is the
- "cdtester" utility (appended) - most audio player programmers seem to be
- better musicians than programmers. ;-)
- With the CR-56x and the CD200 drives, the reading of audio frames is possible.
- This is implemented by an IOCTL function which reads READ_AUDIO frames of
- 2352 bytes at once (configurable with the "READ_AUDIO" define, default is 0).
- Reading the same frame a second time gives different data; the frame data
- start at a different position, but all read bytes are valid, and we always
- read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame
- at once possibly misses some chunks at each frame boundary. This lack has to
- get corrected by external, "higher level" software which reads the same frame
- again and tries to find and eliminate overlapping chunks (24-byte-pieces).
- The transfer rate with reading audio (1-frame-pieces) currently is very slow.
- This can be better reading bigger chunks, but the "missing" chunks possibly
- occur at the beginning of each single frame.
- The software interface possibly may change a bit the day the SCSI driver
- supports it too.
- With all but the CR-52x drives, MultiSession is supported.
- Photo CDs work (the "old" drives like CR-521 can access only the first
- session of a photoCD).
- At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to
- convert photo CD image files and Gerd Knorr's viewing utility.
- The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with
- CR-56x drives, and currently not more than 500 kB/sec (usually less than
- 250 kB/sec) with the Teac quad speed drives.
- XA (PhotoCD) disks with "old" drives give only 50 kB/sec.
- This release consists of
- - this README file
- - the driver file linux/drivers/cdrom/sbpcd.c
- - the stub files linux/drivers/cdrom/sbpcd[234].c
- - the header file linux/drivers/cdrom/sbpcd.h.
- To install:
- -----------
- 1. Setup your hardware parameters. Though the driver does "auto-probing" at a
- lot of (not all possible!) addresses, this step is recommended for
- everyday use. You should let sbpcd auto-probe once and use the reported
- address if a drive got found. The reported type may be incorrect; it is
- correct if you can mount a data CD. There is no choice for you with the
- type; only one is right, the others are deadly wrong.
- a. Go into /usr/src/linux/drivers/cdrom/sbpcd.h and configure it for your
- hardware (near the beginning):
- a1. Set it up for the appropriate type of interface board.
- "Original" CreativeLabs sound cards need "SBPRO 1".
- Most "compatible" sound cards (almost all "non-CreativeLabs" cards)
- need "SBPRO 0".
- The "no-sound" board from OmniCd needs the "SBPRO 1" setup.
- The Teac 8-bit "no-sound" boards need the "SBPRO 1" setup.
- The Teac 16-bit "no-sound" boards need the "SBPRO 3" setup.
- All other "no-sound" boards need the "SBPRO 0" setup.
- The Spea Media FX and Ensoniq SoundScape cards need "SBPRO 2".
- sbpcd.c holds some examples in its auto-probe list.
- If you configure "SBPRO" wrong, the playing of audio CDs will work,
- but you will not be able to mount a data CD.
- a2. Tell the address of your CDROM_PORT (not of the sound port).
- a3. If 4 drives get found, but you have only one, set MAX_DRIVES to 1.
- a4. Set DISTRIBUTION to 0.
- b. Additionally for 2.a1 and 2.a2, the setup may be done during
- boot time (via the "kernel command line" or "LILO option"):
- sbpcd=0x320,LaserMate
- or
- sbpcd=0x230,SoundBlaster
- or
- sbpcd=0x338,SoundScape
- or
- sbpcd=0x2C0,Teac16bit
- This is especially useful if you install a fresh distribution.
- If the second parameter is a number, it gets taken as the type
- setting; 0 is "LaserMate", 1 is "SoundBlaster", 2 is "SoundScape",
- 3 is "Teac16bit".
- So, for example
- sbpcd=0x230,1
- is equivalent to
- sbpcd=0x230,SoundBlaster
- 2. "cd /usr/src/linux" and do a "make config" and select "y" for Matsushita
- CD-ROM support and for ISO9660 FileSystem support. If you do not have a
- second, third, or fourth controller installed, do not say "y" to the
- secondary Matsushita CD-ROM questions.
- 3. Then do a "make dep", then make the kernel image ("make zlilo" or similar).
- 4. Make the device file(s). This step usually already has been done by the
- MAKEDEV script.
- The driver uses MAJOR 25, so, if necessary, do
- mknod /dev/sbpcd b 25 0 (if you have only one drive)
- and/or
- mknod /dev/sbpcd0 b 25 0
- mknod /dev/sbpcd1 b 25 1
- mknod /dev/sbpcd2 b 25 2
- mknod /dev/sbpcd3 b 25 3
- to make the node(s).
- The "first found" drive gets MINOR 0 (regardless of its jumpered ID), the
- "next found" (at the same cable) gets MINOR 1, ...
-
- For a second interface board, you have to make nodes like
- mknod /dev/sbpcd4 b 26 0
- mknod /dev/sbpcd5 b 26 1
- and so on. Use the MAJORs 26, 27, 28.
- If you further make a link like
- ln -s sbpcd /dev/cdrom
- you can use the name /dev/cdrom, too.
- 5. Reboot with the new kernel.
- You should now be able to do
- mkdir /CD
- and
- mount -rt iso9660 /dev/sbpcd /CD
- or
- mount -rt iso9660 -o block=2048 /dev/sbpcd /CD
- and see the contents of your CD in the /CD directory.
- To use audio CDs, a mounting is not recommended (and it would fail if the
- first track is not a data track).
- Using sbpcd as a "loadable module":
- -----------------------------------
- If you do NOT select "Matsushita/Panasonic CDROM driver support" during the
- "make config" of your kernel, you can build the "loadable module" sbpcd.o.
- Read /usr/src/linux/Documentation/modules.txt on this.
- If sbpcd gets used as a module, the support of more than one interface
- card (i.e. drives 4...15) is disabled.
- You can specify interface address and type with the "insmod" command like:
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0
- or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1
- or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2
- where the last number represents the SBPRO setting (no strings allowed here).
- Things of interest:
- -------------------
- The driver is configured to try the LaserMate type of interface at I/O port
- 0x0340 first. If this is not appropriate, sbpcd.h should get changed
- (you will find the right place - just at the beginning).
- No DMA and no IRQ is used.
- To reduce or increase the amount of kernel messages, edit sbpcd.c and play
- with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug").
- Don't forget to reflect on what you do; enabling all DBG_xxx switches at once
- may crash your system, and each message line is accompanied by a delay.
- The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to
- specify "block=2048" as a mount option. Doing this will disable the direct
- execution of a binary from the CD; you have to copy it to a device with the
- standard BLOCK_SIZE (1024) first. So, do not use this if your system is
- directly "running from the CDROM" (like some of Yggdrasil's installation
- variants). There are CDs on the market (like the German "unifix" Linux
- distribution) which MUST get handled with a block_size of 1024. Generally,
- one can say all the CDs which hold files of the name YMTRANS.TBL are defective;
- do not use block=2048 with those.
- Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With
- these, you can configure the driver for some special things.
- You can use the appended program "cdtester" to set the auto-eject feature
- during runtime. Jeff Tranter's "eject" utility can do this, too (and more)
- for you.
- There is an ioctl CDROMMULTISESSION to obtain with a user program if
- the CD is an XA disk and - if it is - where the last session starts. The
- "cdtester" program illustrates how to call it.
- Auto-probing at boot time:
- --------------------------
- The driver does auto-probing at many well-known interface card addresses,
- but not all:
- Some probings can cause a hang if an NE2000 ethernet card gets touched, because
- SBPCD's auto-probing happens before the initialization of the net drivers.
- Those "hazardous" addresses are excluded from auto-probing; the "kernel
- command line" feature has to be used during installation if you have your
- drive at those addresses. The "module" version is allowed to probe at those
- addresses, too.
- The auto-probing looks first at the configured address resp. the address
- submitted by the kernel command line. With this, it is possible to use this
- driver within installation boot floppies, and for any non-standard address,
- too.
- Auto-probing will make an assumption about the interface type ("SBPRO" or not),
- based upon the address. That assumption may be wrong (initialization will be
- o.k., but you will get I/O errors during mount). In that case, use the "kernel
- command line" feature and specify address & type at boot time to find out the
- right setup.
- For everyday use, address and type should get configured within sbpcd.h. That
- will stop the auto-probing due to success with the first try.
- The kernel command "sbpcd=0" suppresses each auto-probing and causes
- the driver not to find any drive; it is meant for people who love sbpcd
- so much that they do not want to miss it, even if they miss the drives. ;-)
- If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is
- initially disabled and needs an explicit kernel command to get activated.
- Once activated, it does not stop before success or end-of-list. This may be
- useful within "universal" CDROM installation boot floppies (but using the
- loadable module would be better because it allows an "extended" auto-probing
- without fearing NE2000 cards).
- To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within
- sbpcd.h.
- Setting up address and interface type:
- --------------------------------------
- If your I/O port address is not 0x340, you have to look for the #defines near
- the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and
- change CDROM_PORT to the address of your CDROM I/O port.
- Almost all of the "SoundBlaster compatible" cards behave like the no-sound
- interfaces, i.e. need SBPRO 0!
- With "original" SB Pro cards, an initial setting of CD_volume through the
- sound card's MIXER register gets done.
- If you are using a "compatible" sound card of types "LaserMate" or "SPEA",
- you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too...
- Using audio CDs:
- ----------------
- Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see
- README.aztcd from the Aztech driver package) should work.
- The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants
- "/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the
- appropriate links to use them without the need to supply parameters.
- Copying audio tracks:
- ---------------------
- The following program will copy track 1 (or a piece of it) from an audio CD
- into the file "track01":
- /*=================== begin program ========================================*/
- /*
- * read an audio track from a CD
- *
- * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de>
- * may be used & enhanced freely
- *
- * Due to non-existent sync bytes at the beginning of each audio frame (or due
- * to a firmware bug within all known drives?), it is currently a kind of
- * fortune if two consecutive frames fit together.
- * Usually, they overlap, or a little piece is missing. This happens in units
- * of 24-byte chunks. It has to get fixed by higher-level software (reading
- * until an overlap occurs, and then eliminate the overlapping chunks).
- * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of
- * such an algorithm.
- * This example program further is missing to obtain the SubChannel data
- * which belong to each frame.
- *
- * This is only an example of the low-level access routine. The read data are
- * pure 16-bit CDDA values; they have to get converted to make sound out of
- * them.
- * It is no fun to listen to it without prior overlap/underlap correction!

- At ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz is an adapted version of

- This is preliminary, as Heiko himself will care about it.
- Known problems:
- ---------------
- Currently, the detection of disk change or removal is actively disabled.
- Most attempts to read the UPC/EAN code result in a stream of zeroes. All my
- drives are mostly telling there is no UPC/EAN code on disk or there is, but it
- is an all-zero number. I guess now almost no CD holds such a number.
