If the CD-R is on a controller RSTS understands (MSCP is the only
option I can think of for this) and is formatted with the RSTS file
structure, and has a boot block in sector zero, it should all just
I haven't personally done this but I'm pretty sure it was done by one
of my friends. I even have some weird "hybrid file system" hacks in
RSTSFLX to let you create a CD-R that's partly ISO and partly RTST,
and bootable. I believe that was used and shown to work, though I
never saw the results.
If you have the files, RSTSFLX can make a bootable disk image for you,
so you can try this yourself.
