  It certainly does.  But now I can't get it to boot at all...I don't 
know if there's a clue here or not.  I just reinstalled the tape 
controller (TMSCP), and now that's the only mscpbus (mtc0 at uba0, 
mscpbus0 at mtc0) that it finds.  That's on a different board (a Pertec 
interface), not the CMD SCSI board.  The install kernel won't even boot 
from CD now.

  Of course proving a negative is hard, but I've tried >20 times, and 
it definitely would've booted by now in its previous configuration.

  VMS boots fine and sees the disks and tape.
