You may already know, but... Please note that a VMS CD-ROM bootable image is
not ISO  9660 formatted. So don't be misleaded if a correctly made image does
not mount on Linux or whatever (or does not show up on Windows): don't take
that as a test! The only way to check for a VMS CD-ROM image integrity is by
having it booted or mounted in VMS.

There is also a vmscd utility that can be used to inspect and extract data
from such an image on Linux. Just look for it with Google.

There is no difference between a VMS CD-ROM bootable image and a classical
VMS hard disk image: they are both structured as an ODS-2 filesystem.
Anyway, VMS can also mount and use ISO  9660 CD-ROM data discs and images.

HTH, :-)

P.S. Itanium-bootable images are different.
