The Coherent Master boot block (which works with FreeBSD quite well)
can boot from either of the first two BIOS drives no matter what
combination of interface technology they use. This means that you can
boot from the SCSI drive in an IDE/SCSI system so long as there is
only one IDE drive and you only want to boot from the SCSI drive
that's mapped to BIOS Drive 81.
