Funny you should ask - I just struggled through this a few days ago. I'm
using an IDE disk for swap.
On my SuperMicro P6DOF, I disabled the IDE controller in the BIOS settings
(which apparently doesn't actually disable it but makes it inelligible for
booting). Then I boot from the SCSI disk normally and the kernel finds the
IDE controller anyway during the various boot probes. From that point on,
the IDE drive is normally accessable.
A word of warning however. LILO just cannot deal with that IDE disk being
there when I try to update the MBR on the SCSI disk. I says something about
sda1 not being the "first disk". The result was a MBR that printed 10101010
ad nauseum. I had to power off the IDE drive, reboot the system, run LILO,
power up the IDE drive and reboot in order to use LILO to update the SCSI
disk's MBR.
YMMV I guess...
