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 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. - -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.
