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?
Thanks,
David

What's the controller? My UC07 can and does boot RSTS/E from a CDROM.

Does it come all the way up, and can you install RSTS/E from it?

It comes up as well as a read-only disk can. I did manage to make
installable CDs for each of the layered products though.

get out. can you provide an iso image?
(i've clearly been hanging around my 11 yo daughter too much when I use
phrases like, "get out" :-)
Still, I'd like to try - will it boot on an 11/23+? (kdf11-b I think)

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.

Try this, where x is a number.
>>b dubx
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.

IIRC, it should be DUx: It's been a while since I booted my PDP-11,
and I've never put one in a MicroVAX. Here is the manual.
ftp://ftp.avanthar.com/dan/viking_scsi/
The important question is what version are your ROMs. I did a bunch
of work with these boards a few years ago, and as near as I was able
to determine it you need a fairly new version of firmware to use a
CD. I believe that you need higher than V3.4 firmware. I've used
DEC RRD-42, Plextor 6x & 8x caddy drives with the Viking QDT. As
I've mentioned before the use of caddy drives is in part a personal
choice as the caddy's are handy since there aren't that many PDP-11
CD's. I did try a 4x tray drive that worked in my DEC Alpha's, and
it wouldn't work.

This looks like exactly what I'm looking for but unfortunately I
don't seem to be able to get the files from that FTP site. At first I
got a directory of what was there but when I tried to copy files I
got errors. Now I can't even connect. Is there a trick to getting
these files?

Short answer, yes.
Long answer, it depends on if the SCSI controller will support a
CD-ROM. I'd recommend trying a Plextor SCSI CD-ROM drive set to
512-byte blocks, or a DEC CD-ROM drive.

They should be able to, if the SCSI controller supports MSCP.
