Firmware archive for the ASUS X553MA notebook, 3.27 MB in ZIP format, without a board revision stated in the name. Technicians write this image to the SPI BIOS chip with a programmer when the laptop powers on but shows no display, or after a failed update. Several board revisions exist for many ASUS models, so compare the PCB marking before use. Always dump and save the original chip first, and check that the image size corresponds to the chip capacity.
