CONFIG_CDU31A
  These CD-ROM drives have a spring-pop-out caddyless drawer, and a
  rectangular green LED centered beneath it.  NOTE: these CD-ROM
  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 at
  boot time as described in <file:Documentation/cdrom/cdu31a> or fill
  in your parameters into <file:drivers/cdrom/cdu31a.c>.  Try "man
  bootparam" or see the documentation of your boot loader (lilo or
  loadlin) about how to pass options to the kernel.

  If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called cdu31a.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_MCD
  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). Please also the file
  <file:Documentation/cdrom/mcd>.

  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 you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called mcd.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_MCD_IRQ
  This allows you to specify the default value of the IRQ used by the
  driver. This setting can be overridden by passing the "mcd="
  parameter to the kernel at boot time (or at module load time if you
  said M to "Standard Mitsumi CD-ROM support").

CONFIG_MCD_BASE
  This allows you to specify the default value of the I/O base address
  used by the driver. This setting can be overridden by passing the
  "mcd=" parameter to the kernel at boot time (or at module load time
  if you said M to "Standard Mitsumi CD-ROM 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 LU-005,
  FX-001 or FX-001D CD-ROM 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. Please read the file
  <file:Documentation/cdrom/mcdx>.

  If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called mcdx.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SBPCD
  This driver supports most of the drives which use the Panasonic or
  Sound Blaster interface.  Please read the file
  <file:Documentation/cdrom/sbpcd>.

  The Matsushita CR-521, CR-522, CR-523, CR-562, CR-563 drives
  (sometimes labeled "Creative"), the Creative Labs CD200, the
  Longshine LCS-7260, the "IBM External ISA CD-ROM" (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
  <file:drivers/cdrom/sbpcd.h> and set "DISTRIBUTION 0" there.

  This driver can support up to four CD-ROM controller cards, and each
  card can support up to four CD-ROM drives; if you say Y here, you
  will be asked how many controller cards you have.  If compiled as a
  module, only one controller card (but with up to four drives) is
  usable.

  If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called sbpcd.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_AZTCD
  This is your driver if you have an Aztech CDA268-01A, Orchid
  CD-3110, Okano or Wearnes CDD110, Conrad TXC, or CyCD-ROM CR520 or
  CR540 CD-ROM drive.  This driver -- just like all these CD-ROM
  drivers -- is NOT for CD-ROM drives with IDE/ATAPI interfaces, such
  as Aztech CDA269-031SE. Please read the file
  <file:Documentation/cdrom/aztcd>.

  If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called aztcd.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_CDU535
  This is the driver for the older Sony CDU-535 and CDU-531 CD-ROM
  drives. Please read the file <file:Documentation/cdrom/sonycd535>.

  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called sonycd535.o. If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_GSCD
  If this is your CD-ROM drive, say Y here.  As described in the file
  <file:Documentation/cdrom/gscd>, you might have to change a setting
  in the file <file:drivers/cdrom/gscd.h> before compiling the
  kernel.  Please read the file <file:Documentation/cdrom/gscd>.

  If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
  file system support" below, because that's the file system used on
  CD-ROMs.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called gscd.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_OPTCD
  This is the driver for the 'DOLPHIN' drive with a 34-pin Sony
  compatible interface. It also works with the Lasermate CR328A. If
  you have one of those, say Y. This driver does not work for the
  Optics Storage 8001 drive; use the IDE-ATAPI CD-ROM driver for that
  one. Please read the file <file:Documentation/cdrom/optcd>.

  inserted in and removed from the running kernel whenever you want).
  The module will be called optcd.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SJCD
  If this is your CD-ROM drive, say Y here and read the file
  <file:Documentation/cdrom/sjcd>. You should then also say Y or M to
  "ISO 9660 CD-ROM file system support" below, because that's the
  file system used on CD-ROMs.
