   Right for what?  This is not a useful description of either
of these "two install files".  I'd guess that anything called
".BCK" might be a BACKUP save set, which would be useful only
to BACKUP.

   If the "DVD isn't bootable", then from what, exactly, did
you boot?  And how is this compatible with "seems to work"?
My grasp on EFI details is still tenuous, but I believe that
you need to do more than pop a DVD into the hole to get the
thing to appear in the EFI Boot Manager's "Please select a
boot option" list.  Dropping down to the "Boot Option
Maintenance Menu" can be useful, as can wandering around using
the "EFI Shell [Built-in]"

   This isn't a VAX or Alpha, where ">>>boot <device>" does
the job.

   VMS systems can do DHCP and TFTP, too.

   Seems unlikely.  I doubt that EFI does BACKUP.
