Can the MicroVAX II or KDJ11-A boot off of 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.
