Working BIOS and EC firmware set for the ASUS X551MA, board revision 2.0, built around the Celeron N2920 processor with an ITE IT8985E embedded controller. The RAR archive should hold both the system BIOS image and the keyboard controller firmware, reported as working. Use it when a board fails to power on or loops after corrupted flash. Back up the original SPI chip with a programmer before writing, confirm the revision printed on the PCB is 2.0, and make sure the image size matches the flash chip capacity.
