For what it's worth, I've only been able to get my CDROM (Creative 4x, I
forget the model right now) to work if there is a disk attached to the same
controller.  Apart from that it doesn't care if it's on the primary
(motherboard) or secondary (SB16 IDE) controller, of whether it's the
master or slave.

If the CDROM is the only device on either controller, the controller is
probed correctly at boot time but the CDROM never gets detected.  Since my
onboard controller turned out to be ATAPI friendly, when I finally get the
2.1 CD I will just move my second HD onto the secondary port and put the
CDROM on the primary, as a slave (as you have apparently done).

OS/2 is currently happy with the CDROM as the lone device on the secondary
port -- it detects it as a generic IDE CDROM.  It seems you're SOL trying
to have things this way under FreeBSD with the current ATAPI drive though.
Not that I'm complaining -- three cheers to the developers for getting my
'orrible little CD to work at all :)
