Excellent. One thing I would suggest is that rather than patch Etherboot
to look for this ROM, this flash register itself as an extension BIOS
and provide its services via BIOS calls (I'm sure you can find some
suitable numbers). Etherboot (and any other software for that matter,
can then test the existence of and access these services via BIOS calls,
rather than hardwiring knowledge of this flash into the software. Then
this BIOS call can be generalised for other non-volatile devices instead
of having device specific code in every piece of software.
