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.
