Small 134 KB RAR archive for the ASUS X540LJ notebook, with 2.0 most likely the mainboard revision. The name does not state the content type, but at this size it probably holds a BIOS or EC image rather than a schematic. Check the files inside and compare them with the revision printed on your board before use. Firmware images for ASUS laptops are usually written with an SPI programmer after reading and saving the original chip, and the image size must match the flash capacity.
