Piece of cake;  The ESDI drive will have to remain as the boot device.  You
will need to disable the floppy controller on the 1542B.  Jumpers exist
for that.  Just add it like you would any disk drive.  SCO will ask the
right questions.

I don't believe ODT will support the SyQuest drive. At least it may not
spin it up, lock it, spin it down and unlock it.  If the media has already
spun up, it might work.
