Right for burning to a DVD.

It is installing now, so I can't go look at EFI.  I believe
the SCSI disk came out as fs0: and the DVD as fs1:
I CD to fs1: cd to, I believe, the VMS directory, and then run
the appropriate EFI file.

It might be with the appropriate boot option it would.
I believe this previously ran linux, or at least something
other than VMS.  Is it hard to make bootable DVDs?

I notice.

Has anyone installed through the net?
