ASUS X451MA BIOS or firmware package for board revision 2.1, compressed in a 2.89 MB RAR archive. Such a dump is normally used to recover a laptop with corrupted firmware by reflashing the SPI BIOS chip with an external programmer like a CH341A. Check that the revision printed on your mainboard is 2.1, always back up the existing chip contents first, and ensure the extracted image size equals the flash chip capacity before writing.
