BIOS image for ASUS K451L and S451 laptops with the onboard memory disabled, so the board runs from an installed SO-DIMM. Useful when a soldered RAM chip is defective and replacement is impractical. The name states no board revision, so confirm compatibility against your own dump and the PCB markings. Packed as a 907 KB ZIP archive, the image is intended for writing to the SPI flash with an external programmer. Save the original firmware first, since it holds the unit serial and network MAC data.
