Firmware archive for the ASUS X507MA notebook, labeled AS in the name, possibly a regional or sub-variant tag that cannot be confirmed. The 5.67 MB RAR states no board revision or BIOS version, so inspect it before use. Technicians flash such images to the SPI BIOS chip with a programmer to recover a board that will not boot.
