-This README belongs to release 3.9 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 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-years 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.
-
-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 - f.e. 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". Support is under construction
- - CD200F should work, CD200 is still giving problems.
-Drive detection and playing audio should work. 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 has to get a point of
-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 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, ...) and with the "no-sound" cards (Panasonic CI-101P,
-LaserMate, WDH-7001C, Longshine LCS-6853, TEAC ...).
-
-It finally works now with the "configurable" interface "Sequoia S-1000", too,
-which is found 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 within
-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 /usr/include/linux/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.
-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.
-
-With the CR-562 and CR-563 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.

-- the header file linux/include/linux/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
- every-day 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 the right, the others are deadly wrong.
-
- a. Go into /usr/src/linux/include/linux/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.
- All other "no-sound" boards need the "SBPRO 0" setup.
- Possibly some TEAC "no-sound" boards need the "SBPRO 1" setup.
- The Spea Media FX sound card needs "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=0x230,SoundBlaster
- or
- sbpcd=0x320,LaserMate
- or
- sbpcd=0x330,SPEA
- 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".
- 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 else).
-
-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 to 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/README.modules 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
-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 what you do; enabling all DBG_xxx switches at once
-may crash your system.
-
-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) before. 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 (f.e. EJECT and JUKEBOX). With
-that, 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 every-day 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 cards 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, do the appropriate
-links for using them without the need of supplying 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!
