I've never seen anything "official" in writing, but my experience agrees
w/ Keary's comments regarding slaving off ATAPI devices. A generally
accepted practice w/ (2) IDE channels is to put the master and slave
hard drives on channel 1, and the CD drive on channel 2. As long as
they're jumpered correctly, I've never had an issue.

IIRC, it is recommended that you don't, in general, slave a drive from
an
ATAPI device. Can you reverse the order (CDRW-slave, Drive-master)?
Perhaps
you'll have better results. This could be why the drive is not showing
as
ultra1, a proper secondary slave drive.
You may want to check out Apple's docs on open firmware, as that may
shed
light on why OF is identifying the drives so.
