I tried that
That syntax works fine for hfs and msdos images on the harddrive but does not
seem to work for the cdrom. I have even copied a is9660 image to the beginning
of the harddrive and was able to boot from that, but from the actual cdrom.
it gives one of two messages, one given even for non-existing files about
unrecognized image and for "boot cd:0,ofwboot.elf" unable to load file.
something about load-size=0.
