BIOS dump for the ASUS X455LJ laptop motherboard, revision 2.1, packed as a 3.45 MB RAR. Use it to reprogram the BIOS chip with an external programmer when the machine has no display or fails after an interrupted update. Confirm that the PCB revision marking reads 2.1, since images for other revisions may not run. Compare the file size with the chip capacity, and read out the original chip first to keep serial and board data.
