   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).

 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

+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

+  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.
