I did try alternate roots, as that was my first thought also. But it
didn't work.
Actually, the discs don't even look to have the files necessary for a
"full" (or even minimal) VMS system to run from CD-ROM.

Andreas,
I know how to boot a CD-ROM in a VAX. I've got the VMS 7.2 hobbyist,
VMS 7.2 regular distrib, and VMS 7.3 regular distrib, and when I boot
them all, I just go into standalone backup. I thought maybe there was
some "trick" I didn't know about to boot into a regular VMS system.

Parts of my brain is saying "use an alternate root", but I'm not sure
where that came from...

Bob,
to PC users, this may sound like I am joking, but I am serious: to
boot VMS from CD, you do the same things you would do with any other
disk (isn't this what abstraction layers are good for?): assuming that
your CD ROM drive is DKA400 because you selected SCSI
ID #4, you will
insert the disk and issue the command
>> BOOT DKA400
at the console prompt. That's it! - No magic with a special BIOS that
would need to support SCSI or CD booting or other wizardry.
A VAX can even be booted directly from tape, but this will normally
take you into the standalone backup (S/A backup), a reduced
functionality operating system that is only made for restoring backups in cases where no other operating system is available
for use. Alphas
do not have this feature any more.
Regards,
Andreas

I believe that the VAX V6.1 CDs were the
first ones that could be booted directly
into OpenVMS (rather than just being
able to boot S/A BACKUP to restore
the .B saveset).
How does one go about booting the CD directly into OpenVMS?
