will just cause this configure script to skip all the questions
about these CDROM drives. If you are unsure what you have, say Y and
find out whether you have one of the following drives.
For each of these drivers, a file Documentation/cdrom/<driver_name>
exists. Especially in cases where you do not know exactly which kind
of drive you have you should read there.
Most of these drivers use a file include/linux/<driver_name>.h where
you can define your interface parameters and switch some internal
goodies.
All these CDROM drivers are also usable as a module (= code which can
be inserted in and removed from the running kernel whenever you want).
If you want to compile them as module, say M instead of Y and read
Documentation/modules.txt.
If you want to use any of these CDROM drivers, you also have to say
Y to "ISO9660 cdrom filesystem support" below (this answer will get
"defaulted" for you if you enable any of the Linux CDROM drivers).
Sony CDU31A/CDU33A CDROM driver support
Sony CDU31A/CDU33A CDROM support
CONFIG_CDU31A
These CDROM drives have a spring-pop-out caddyless drawer, and a
rectangular green LED centered beneath it. If you have one of these,
say Y here and also to "ISO9660 cdrom filesystem support"
below. Read the CDROM-HOWTO, available via ftp (user: anonymous)
from sunsite.unc.edu:/pub/Linux/docs/HOWTO. Also, read
Documentation/cdrom/cdu31a. NOTE: this CDROM drive won't be
auto detected by the kernel at boot time; you have to provide its
specifications as an option to the kernel as described in the above
README. See the documentation of your boot loader (lilo or loadlin)
about how to pass options to the kernel. The lilo procedure is also
explained in the SCSI-HOWTO. This driver is also available as a
module ( = code which can be inserted in and removed from the
running kernel whenever you want). If you want to compile it as a
module, say M here and read Documentation/modules.txt. If unsure,

NOTE: these CDROM drives will not be auto detected by the kernel at
boot time; you have to provide the interface address as an option to
the kernel as described in Documentation/cdrom/cdu31a or fill in your

the kernel. The lilo procedure is also explained in the SCSI-HOWTO.
Standard Mitsumi [no XA/Multisession] CDROM support
CONFIG_MCD
This is a very common CDROM drive. In some models, the whole drive
chassis slides out for cd insertion. Later models use a motorized
tray type mechanism. If you have one of these CDROM drives, say Y
here and also to "ISO9660 cdrom filesystem support" below. Read the,
available via ftp (user: anonymous) CDROM-HOWTO from
sunsite.unc.edu:/pub/Linux/docs/HOWTO. Note that this driver does
not support XA or MultiSession CDs (PhotoCDs). There's a new
experimental driver in the 1.3 kernels that can do this, but cannot
play your music CDs. If you want that one, say N here. If the driver
doesn't work out of the box, you might want to have a look at
linux/include/linux/mcd.h. If your Mitsumi CDROM drive is of type
IDE/ATAPI, then you have to say N here and should have said Y to
"Support for IDE/ATAPI CDROMs" above. This driver is also available
as a module ( = code which can be inserted in and removed from the
running kernel whenever you want). If you want to compile it as a
module, say M here and read Documentation/modules.txt. If unsure,
say N now.
Experimental Mitsumi [XA/MultiSession, no Audio] support
This is the older of the two drivers for the older Mitsumi models
LU-005, FX-001 and FX-001D. This is not the right driver for the
FX-001DE and the triple or quad speed models (all these are IDE/ATAPI
models).
With the old LU-005 model, the whole drive chassis slides out for
cd insertion. The FX-xxx models use a motorized tray type mechanism.
Note that this driver does not support XA or MultiSession CDs (PhotoCDs).
There is a new driver (next question) which can do this. If you want
that one, say N here.
If the driver doesn't work out of the box, you might want to have
a look at linux/include/linux/mcd.h.
Mitsumi [XA/MultiSession] support
CONFIG_MCDX
Use this driver if you want to be able to read XA or MultiSession
CDs (PhotoCDs) as well as ordinary CDs with your Mitsumi CDROM
drive. In addition, this driver uses much less kernel memory than
the old one, if that is a concern. However, you won't be able to
play audio CDs. If you have two Mitsumi CDROM drives, you can use
the old driver for one and the new for the other;
Documentation/cdrom/mcdx explains how. If you want to compile this
as a module ( = code which can be inserted in and removed from the
running kernel whenever you want), say M here and read
Documentation/modules.txt.
CDs (PhotoCDs) as well as ordinary CDs with your Mitsumi LU-005,
FX-001 or FX-001D CDROM drive. In addition, this driver uses much less
kernel memory than the old one, if that is a concern. This driver is
able to support more than one drive, but each drive needs a separate
interface card.
Matsushita/Panasonic CDROM driver support
Matsushita/Panasonic/Creative, Longshine, TEAC CDROM support
CONFIG_SBPCD
The Creative Labs Soundblaster CD drives as well as Longshine and
IBM External ISA also fall under this category. It has a uniquely
shaped faceplate, with a caddyless motorized drawer which makes it
recognizable, but has no external brand markings. Some Soundblaster
drives have a caddy and manual loading/eject, but still no external
markings. If you have one of these, say Y here and also to "ISO9660
cdrom filesystem support" below. This driver can support up to four
CDROM controllers, each of which can support up to four CDROM
drives; you will be asked how many controllers you have. Read
Documentation/cdrom/sbpcd and include/linux/sbpcd.h in the kernel
source and the CDROM-HOWTO, available via ftp (user: anonymous) from
sunsite.unc.edu:/pub/Linux/docs/HOWTO. If unsure, say N. If you
want to compile this as a module ( = code which can be inserted in
and removed from the running kernel whenever you want), say M here
and read Documentation/modules.txt.
Matsushita/Panasonic second CDROM controller support
This driver supports most of the drives which use the Panasonic or
SoundBlaster interface.
The Matsushita CR-521, CR-522, CR-523, CR-562, CR-563 drives (sometimes
labelled "Creative"), the CreativeLabs CD200, the Longshine LCS-7260,
the "IBM External ISA CDROM" (in fact a CR-56x model), the TEAC CD-55A
fall under this category. Some other "electrically compatible" drives
(Vertos, Genoa, some Funai models) are currently not supported; for the
Sanyo H94A drive currently a separate driver (asked later) is responsible.
Most drives have a uniquely shaped faceplate, with a caddyless motorized
drawer, but without external brand markings. The older CR-52x drives have
a caddy and manual loading/eject, but still no external markings.
The driver is able to do an extended auto-probing for interface addresses
and drive types; this can help to find facts in cases you are not sure,
but can consume some time during the boot process if none of the supported
drives gets found.
Once your drive got found, you should enter the reported parameters into
linux/include/linux/sbpcd.h and set "DISTRIBUTION 0" there.
This driver can support up to four CDROM interface cards, and each card
can support up to four CDROM drives; if you say Y here, you will be asked
how many controllers you have. If compiled as a module, only one interface
card (but with up to four drives) is usable.
Matsushita/Panasonic, ... second CDROM controller support
CONFIG_SBPCD2
If you have two CDROM drives of this type that you want to use
simultaneously under Linux, say Y here, otherwise N.
Say Y here only if you have two CDROM controller boards of this type
(usually only if you have more than four drives). You should enter
the parameters for the second, third and fourth interface card into
linux/include/linux/sbpcd.h before compiling the new kernel.
Aztech/Orchid/Okano/Wearnes (non IDE) CDROM support
Aztech/Orchid/Okano/Wearnes/TXC (non IDE) CDROM support
CONFIG_AZTCD
If you have a CDA268-01A, ORCHID CD-3110, OKANO/WEARNES CDD110 or
Conrad TXC CDROM drive, say Y here and also to "ISO9660 cdrom
filesystem support" below. This is NOT for CDROM drives with IDE
interface, such as Aztech CDA269-031SE. (If you have one of those,
you should have said Y to the new IDE driver above.) You want to
read Documentation/cdrom/aztcd and include/linux/aztcd.h in the
kernel source and the CDROM-HOWTO, available via ftp (user:
