BIOS image for the ASUS E402MA laptop mainboard, revision 2.0, in a 3.11 MB ZIP. Use it to reflash the SPI chip when the notebook shows no display, keeps rebooting or was bricked by a failed update. A matching boardview for the same revision helps you find the flash chip and its supply. Confirm the REV marking on the PCB, read and keep the original chip contents with a programmer, and check that the image size equals the chip capacity.
