Correct me if I'm wrong, but can't you use BootVariables to tell OF where
the boot file is and boot directly from an ISO9660 CD-ROM, independent of
any other ports on the disk.  That is, can't you give OF a full path name
to boot from?  This would not require MacOS (or license) and should not
require the user to use the OF command line.

Perhaps the ISO support is broken, like so many other things.  Perhaps
there is some problem I don't know about in the second stage of the boot
