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.
The trick is that instead of booting with:
>> BOOT DKA100:
you do something like:
>> BOOT/R5:10000000 DKA100:
assuming that the alternate root is [SYS1].
I just looked on a V7.1 VAX binary disk and
it looks very much like [SYS0] (i.e. the
default boot) is S/A BACKUP and [SYS1]
(i.e. as above) is a full OpenVMS boot. Obviously
it's booted off a read-only medium so you do not
get to mess around too much, but it should be
enough to get your install done or fixup your
disk or whatever.
