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 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. 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
|
|
Heiko Eissfeldt's digital-audio to .WAV converter (the original is there, too).
|

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.
