BIOS dump for the ASUS X550CC laptop mainboard, revision 2.0, marked TEST OK in the name, meaning it was reported working after flashing. The RAR archive is 3.70 MB. Technicians program this kind of image into the SPI flash chip with an external programmer to revive a board with corrupted firmware. Check that the revision on your PCB is 2.0, as ASUS images can differ between revisions, save the original chip contents before erasing, and confirm the image size agrees with the chip capacity.
