I'm not sure about the rest of the guys here, but _my_ problem is not
that SYS_INST won't boot, but that disklabel that comes in SYS_INST
can't find any of my scsi disks.
BTW ... BSD4.4 from berkeley shipped with an hp300 dd that included the
disklabel, etc. I got one of those to boot, but it fails in another wierd
way. I'll be spending more time with that, though before I give a final
determination.
