[coreboot] Question about call LegacyBIOS in the memory(GSoC__SCSI boot)

I finally find that in arch/x86/, function pci_dev_init() called
run_bios() in util/x86emu.
The order is :
pci_dev_init
      -->pci_rom_probe
      -->run_bios(vm86.c/biosemu.c)

my problem is:
in pci_rom_probe, most rom_address is 0 and return NULL;
only one rom_address is 0x c0000 but the rom_header->signature is 0 so
it also return NULL.

So no run_bios is running.

How can I get run_bios() running and test my code in it?

Best regards.
