Why would it have a 55 AA signature? It's not a PXE ROM image, it's an
Etherboot image meant to be loaded with PXE. See the doco.

See Config for documentation of BACKOFF_LIMIT.

makerom has been rewritten in Perl (currently in CVS) so if you want to
see your changes considered, you'll have to work on that version.

Post away.
