Recent versions of QEmu place gPXE in the virtual NIC's rom.  I'm sure
there is some command option to disable it (or you could just do "-net
none").

Hrmm - the PNP support in SeaBIOS is really just a stub.  The 0x50
function isn't supported (it looks to be an smbios call).

Yeah, actually the option ROM does make a lot of smbios call
but I cannot talk about it because I'm under NDA.

Is there another file besides pnpbios.c which implement the stub?
I grep-ed through the SeaBIOS source but that's the only one I found.
