According to what Mr. Sokolov has said, there is a way to bet the
VS3100/M76 to boot from the hard disks. I have such a unit with two rz24's
as id's 0&1 as well as other disks tied to scsi host #1. Here's the
disklabel:

# /dev/rsd0c:
type: SCSI
disk: rz24
label: start-me-up
flags:
bytes/sector: 512
sectors/track: 38
tracks/cylinder: 8
sectors/cylinder: 304
cylinders: 1348
total sectors: 409792
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds
track-to-track seek: 0	# milliseconds
drivedata: 0 

5 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:    69920        0    4.2BSD     1024  8192    16 	# (Cyl.    0 - 229)
  b:    68096    69920      swap                    	# (Cyl.  230 - 453)
  c:   409792        0    unused        0     0       	# (Cyl.    0 - 1347)
  d:   409792        0      boot                    	# (Cyl.    0 - 1347)
  e:   271776   138016    4.2BSD     1024  8192    16 	# (Cyl.  454 - 1347)

What must I correct to get this working? Which copy of BOOT would I need
to use? Which kernel must I use? ( iave have at least seven versions from
1.2G to the latest from Multivac)
