If i am correct this comes from src/northbridge/intel/sandybridge/acpi.c line 95:
printk(BIOS_DEBUG, "GET_VBIOS: %x %x %x %x %x\n", oprom->signature, pcir->vendor, pcir->classcode[0], pcir->classcode[1], pcir->classcode[2]);
But Signature should be 0x55aa:

Greetings,
i am trying to get coreboot running on x230 and have some trouble regarding the execution of the vga option rom.
As far as i understand seabios should load all option roms existing in cbfs, but it won't.
Only if i set CONFIG_VGA_ROM_RUN=y vga option rom gets loaded but whether coreboot nor seabios output is displayed. Only a blinking cursor idles until boot continues.

Any idea what is going wrong here?
