BIOS dump for the ASUS X409JA mainboard at revision 2.0, packed as a 5.04 MB RAR archive. Technicians write such an image into the SPI flash with a programmer when the laptop does not power on properly, shows no display or has a failed update. ASUS often changes layouts and firmware between revisions, so check that the board reads R2.0. Before writing, dump the original chip as a backup, since it may contain unique serial data, and verify the image size matches the chip.
