X551MA-RCLN03 in-built single chip

BIOS .rar 3.09 MB Shared

Firmware for the ASUS X551MA-RCLN03, described in the name as for the in-built single chip, which most likely means a single onboard SPI flash holding the whole image. No board revision is stated, so confirm the board marking on the PCB before use. The dump is for reflashing that chip with an external programmer to recover a board with corrupted BIOS. Read and save the original contents first, since they can carry unit-specific data, and check the file size matches the chip capacity exactly.
