	Prep the RES<whatever>:.  Tell prep it's a scsi drive, custom
definition.  Cylinders: 2097, heads 1, blocks per track 98.  Remember that
the first partition will be Old Filesystem, so I advise using only around 20
cylinders for the first partition, 5 buffers.  Then set up mountlists for
the rest of it (remember to start them one higher than the first partition!)

	Reboot from floppy, and format the partition.  Then install enough of
a WB to startup your main FFS partitions.

	Those numbers are for a LP105S rev 2.3.  If the last partition is
not fully usable (format dies before the end), reduce the number of cylinders
until it works (different revs may have different amounts of space reserved
for mapping).
