Firmware archive for the ASUS A409FB, board revision 2.0, about 5.32 MB. The name only indicates the model and revision, so unpack it to confirm the image and its size. Use it to reprogram the SPI BIOS chip on a laptop that will not POST or that has corrupt firmware. Back up the original chip first, because it holds board-specific data such as serial information. Make sure the image size matches the chip and that the PCB revision reads 2.0.
