BIOS package for the ASUS X551MA laptop, labelled as tested by its preparer. The name does not state a board revision, so check the motherboard markings for the same model before use. It is a 3.09 MB RAR archive that holds the firmware for the SPI flash chip. Repair technicians flash such images with a programmer when the notebook powers on without display or the BIOS is corrupted. Read and back up the original chip first, and make sure the unpacked image matches the flash chip capacity before writing.
