If you have a DOS, create a small DOS partition on that SCSI drive and
next install FreeBSD. FreeBSD's installer will determine the correct
geometory. Onece the geometory is recognized properly, everything will
be fine. You can delete the DOS partition and allocate an entire disk
for FreeBSD if you don't need it.
BTW, why did this happen in 2.0.5? It was OK at least in 950412-SNAP,
wasn't it?
