I've been out of touch with the list for a little while, so I just got
this. Anyway, what would the many aspects be? I was operating on the
assumption that the image I would get or make would have already been
copy/boot'ed so, it should be a bootable image, and if transferred as an
exact image to the CD it should work.

I did finally manage to get my RX02's copied to a VMS machine. The guy
that was helping me (who had the vax/vms machine) was out of town for
awhile. Anyway, we copied an image of a bootable floppy to the VMS
machine, and back to a new floppy, which booted fine with no need to
copy/boot it (since the imagine was already that way). We also used VMS
exchange to may .dsk files. I need to read up a little more on exchange,
but I was thinking if I can work with the .dsk imagines of the ftpable
RT-11 5.03, I should be copy in my program and then copy that to a SCSI
disk, make sure its bootable, and then make an image of it. The .dsk
files seem to be little file on file systems as opposed to just making an
image.

Thanks,

Tom
