BIOS dump for a Sony VAIO mainboard carrying the Quanta number DA0HK5MB6F0 and Sony board code MBX-269, revision F, archived as a RAR of about 2.55 MB. Quanta makes many VAIO boards and uses the DA0 prefix, with MB marking a mainboard and the trailing letters giving the revision. Check that the silkscreen on your PCB shows the same number and Rev F. Back up the existing SPI chip before writing this image with a programmer, and check the image size matches the chip capacity.
