Thanks for the reminder.  The changes you suggested worked just fine.  I/O
is pretty slow, something around 40K/s for both read and write to my SCSI
disk, but it does in fact allow you to run disklabel and newfs.

I wonder what the significant differences are between the VS3100/38+30 vs
the VS3100/76?  There are both using the same NCR chipset right?  The only
difference between the 76 that I'm aware of are that in the 30 and 38, the
SCSI controller is provided on an add in card.  The 76 has the controller
integrated into the system board.

Obviously there are some additional functional differences with how the
integrated controllers and seperate controllers operate.  Where do you
even begin to find the hardware design specifics for these types of things
anymore?
