It all depends on how the controller is configured. In order to
configure the controller, you'll need to make up a cable with a 50-pin
connector on one end, and a serial connector on the other end, to talk
to the device. There's more details in the manual -

Okay, here' s a dumb question. What do I type at the ">>>" prompt
to
boot from the SCSI controller. This is a TD Systems Viking
controller. I tried just "boot" but that seems to attempt to and fail
to boot from the ESDI hard drive. I have the MVII technical manual
and looked up the boot command but all it says is "boot <device>" but
doesn't say what the choices are for "device". What would I enter as
a device name to skip over the ESDI drive and boot from the CD-ROM
attached to the Viking controller? Also, the CD-ROM drive is set for
unit 4 if that makes a difference. It seems all of my removable media devices are
broken (TK50 and
RX50). That leaves me wondering if I can boot a MicroVAX II or a
KDJ11-A off of a CD-ROM. I have a SCSI controller that should work
with either machine and I have a SCSI CD-ROM drive. Can either of
these machines boot from a SCSI CD-ROM?
As Zane also replied, it depends on the SCSI controller and the
CD-ROM drive. A combination that worked for me is a Dilog SQ706A
Q-bus SCSI controller and a Plextor SCSI CD-ROM jumpered to
512-byte block mode. It would not boot correctly without setting
the CD-ROM to 512-byte block mode.
With this combination I was able to boot a KDJ11-A from an XXDP
disk image that I burned onto a CD-ROM, and also boot a KA650 from
the VMS 7.3 distribution disk on CD-ROM.
