Actually, I just figured this out. The Adaptec card has a 'boot
device' option. I didn't realize what this was because the BIOS post
is so vague. I had inadvertently set the master drive on ide3 to be a
boot drive. The Adaptec BIOS then presents this as the first drive on
the controller. Grub just uses the BIOS, so that is what it saw. I had
to reboot the card without any drives (trying to reset it using the
BIOS failed), then with drives on the first channel, then the drive on
the 2nd channel. It all works now! Your 'map drives to different
locations' got me thinking in the right direction. Thanks.
