ASUS E406MA BIOS image for mainboard revision 2.0, supplied as a 5.65 MB ZIP archive. It is aimed at technicians restoring firmware on this compact laptop when it powers but shows no image or loops at startup. Write it to the SPI chip with an external programmer, first reading and saving the existing contents, which hold board-specific data. Confirm the revision silkscreened on the PCB and make sure the image size corresponds to the flash chip capacity before programming.
