BIOS dump in a RAR archive for the ASUS S551 series, model S551LN, motherboard revision 2.2. A technician would write this to the SPI chip with a programmer when the laptop powers on without display, loops on start or fails after an update. Before using it, read the revision printed on the PCB, since ASUS boards of the same model often differ between revisions. Make a full backup of the existing chip, make sure the extracted image matches the chip capacity, and verify the write afterwards.
