Firmware for an ASUS X501 laptop using the X401A mainboard at revision 2.0, as the name states, supplied in a 3.46 MB RAR. ASUS often shares a board between related models, which is why the X401A board serves the X501 here. The dump is used to reflash the SPI BIOS chip with a programmer when the laptop fails to boot or shows no display. Confirm the board name and revision on the PCB, save the original chip, and check the image size matches.
