ZIP archive of nearly 19 MB for the ASUS X421IA laptop, with R2.0 in the name, most likely the mainboard revision. The name does not state the contents, which may include a schematic, boardview or BIOS, so check after extraction. Such packages support tracing power rails, locating components and test points, or reflashing the SPI chip. Make sure the revision printed on your board matches 2.0, and back up any original firmware before writing a new image.
