Original BIOS firmware for the ASUS X455LJ notebook, board revision 3.1, distributed as a 3.34 MB RAR archive. The ORIG tag indicates a dump read from a factory board, though no version or ME status is stated. ASUS revisions often differ in layout and firmware, so confirm that the revision printed on the motherboard is 3.1. Use an SPI programmer to write the image when the laptop shows no display or loops on power, and keep a backup of the existing chip contents before flashing, checking capacity matches.
