Firmware archive for the ASUS X553MA notebook, a fairly large 17.1 MB RAR that likely holds more than one file, such as BIOS images, EC firmware or utilities. The name states no board revision or version, so extract it and identify each image before use. Technicians write the main BIOS image to the SPI flash with a programmer when the laptop is bricked. Check the chip capacity against each image size, compare the mainboard revision printed on the PCB, and read and save the original chip first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
