Well, not exactly. It was a break point in IDA Pro that stops the execution there. Anyway, the log above was for a gPXE ROM which I don't know exactly. It seems "bundled" with SeaBIOS or Coreboot.
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").
The log for my target option ROM was inadvertently not included. Here it is: ------------ [...] pnp call arg1=50 --------------
Hrmm - the PNP support in SeaBIOS is really just a stub. The 0x50 function isn't supported (it looks to be an smbios call). -Kevin

Yeah, actually the option ROM does make a lot of smbios call but I cannot talk about it because I'm under NDA. -Darmawan -- -------------------------------------------------------------------- -= Human knowledge belongs to the world =-
Hi Kevin,

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. Thanks, Darmawan -- -------------------------------------------------------------------- -= Human knowledge belongs to the world =-
