Very sage words indeed!

I'm now much further along than I was the first time I posted. Here are
the URLs I've been working from:

I've also had some back and forth mailing with people from this (and other
lists).

Did that (I used c for x), ran lilo and then recompiled my kernel with some modules that
were missing. Loaded: SCSI CD-ROM support, Enable vendor specific, SCSI
general. Got the list from 
http://homepage.tinet.ie/~mjconry/cdrw_help.html
I already had the other modules compiled directly into the kernel. (i.e.
not as optional modules)

I've been working as root until I get it working.

This still shows nothing.

Ran it as root with the same result.

It isn't loaded because it should be compiled directly into the kernel.

debian:/# mount -t iso9660 /dev/hdc /cdrw (as root)
mount: fs type iso9660 not supported by kernel

*grrr* This is compiled into the kernel. It's not a module (although I
just noticed that some of the SCSI emulation stuff is there as modules so
I may have missed loading some modules somewhere. However ide-scsi is
compiled directly in to the kernel). Back to iso9960: It's got a * under 
File systems --> ISO 9660 CDROM file system support.

Does anyone know of a chart that has the make menuconfig all expanded with
the names of all the modules?
http://www.rhce2b.com/clublinux/RHCE-14.shtml
has a nice little checklist for rebuilding the kernel, but not a guide to
the kernel (for lack of a better term).

Yup. And then recompiled the kernel...

from /etc/lilo.conf:
append="keytimer hdc=ide-scsi"
