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.
Try this, where x is a number.

MSCP controllers are du, each controller is assinged a letter starting
with 'a', and each devices on the controller is assigned a unit
number. On a PDP-11 MSCP controllers are supposed to have unique
device numbers across all controllers but not necessarily so on a MVII
so you could have both dua0 and dub0.
The SCSI ID of the CD-ROM does may not directly map to a unit number,
i.e SCSI ID of 4 probably does not mean MSCP unit number 4. On the
Dilog SQ706A you have to configure the SCSI ID -> MSCP unit number
mapping using the on board firmware utility. Maybe there is a similar
utility somewhere in the Viking controller firmware.
I'm pretty new to this also. I believe ">>>show device" would
display
all of the controllers and attached devices found.
