Installing on a PowerMac/6500 with a TEAC SCSI CD-RW drive, I had to
use the 2.4 kernel because the 2.6 kernel couldn't find a driver for
the CD.


Do you know which module you need for this CD-RW drive?


No.  All I know is that it works fine with the 2.4 kernel.
How can I find out?


/var/log/syslog on 2.4 might tell you.


/var/log/syslog from a recent 2.4 boot is attached to this email.

The (to my eyes) seemingly important part is:

For what it's worth, the MacOS-9 Apple System Profiler says that
it's a CD-W512B (rev 1.0E) manufactured by TEAC.

Also for what it's worth, when I boot the 2.6 kernel and let it run
up thru "detect and mount CD-ROM", then switch to the F2 console
and look in /proc and /dev, I do not see any indication of SCSI
devices at all.  In particular, nothing in /dev/scsi (the directory
exists, but there's nothing in it) and nothing mentioning scsi in
the /proc/ide subdirectory tree.  The machine has a 4GB SCSI disc
and an 80 GB IDE dsic, and, while the ide disc is visible at this
time, the scsi disc is nowhere to be found (/dev/discs show no
trace of it.)   When I do "cat /proc/scsi/scsi" it does not list
any attached devices (neither CD-ROM nor 4GB disc, nor anything
else).


Do you know if it's actually a SCSI drive, or does it run by IDE-SCSI
emulation? That said, we do have ide-scsi in the 2.6 initrd.


It's actually a SCSI drive.  Bus 0 (the on-board SCSI chip), target 3.
The 4 GB  disk is target 0 on the same SCSI bus.

Hope this helps!
