	I have the following connected to scsi host 1 (scsi host 2 is not
used):

dka0 - rz24
dka100 - rz24
dka200 - st41200n seagate (992 MB)
dka300 - dk516 hitachi (1280 MB)
dka400 - dk516 hitachi (1280 MB)
dka500 - rx23 (1440 KB floppy)

I ran the internal SCSI ribbon to a centronics 50 pin female connector in
the back (some sculpting was done to fit it). This is how dka200,dka300
and dka400 are connected. All drives are working.

This is the dislabel data for the first rz24 drive (DKA0)


# /dev/rsd0c:
type: SCSI
disk: rz24

bytes/sector: 512

headswitch: 0		# milliseconds

5 partitions:
#        size   offset    fstype   [fsize bsize   cpg]

Upon powering up and getting the chevron, I entered 'b /3 dka0, and
reveiced the boot prompt. Upon entering 'rom()/netbsd', I received the
following:

?08 SCB ERR2
    PC = 00106399

 83 BOOT SYS
?41 DEVASSIGN, NONE   ( I had done 'set boot none')
i 84 FAIL
>>> 

If I were to do a 'set boot dka0' I would see the following:

>>> b /3 dka0
howto 0x3, bdev 0x2a, booting...done. (31448+22260)
>> NetBSD/vax boot [980110 22:29] <<
: rom()/netbsd

83 BOOT SYS
-DKA0

howto 0x0, bdev 0x2a, booting...done(31448+22260)   (reboot attempt?)
>> NetBSD/vax boot [980110] 22:29] << 
: /netbsd

sdopen: ctlr=0 unit=0 part=0
(the 48's of death show up this time in the same manner as the c8's of
death)


The boot program does not like 'rom()/netbsd'.
