BIOS image for the ASUS X55U laptop, stored as a 2.07 MB RAR; ok in the name suggests the uploader marked it as working. No motherboard number or revision appears, so check the board printed on your PCB and the chip capacity before use. Typical use is reflashing the SPI chip with a programmer such as a CH341A after a failed update or corruption causing no power-on picture. Always read and keep the original contents first, as the old dump may hold serial and licence data worth restoring.
