I didn't have any trouble with the cd booting.  I've got it
set up as my secondary ata master.  It sees my ad0 fine, and
then hangs before showing the drive type for ad1.

This post had ad0 hang using a GA - 8SG800 motherboard.
Maybe also an nforce2 chipset?

I could swear there were others, but the only ones that I could
find quickly were about cdrom problems, not hard drives.
