BIOS image for the ASUS E402WA laptop, board revision 2.1, described in the name as fully working. Packed as a RAR archive of about 2.10 MB. Technicians use such a dump to recover a board with corrupted firmware by writing the SPI flash chip with an external programmer. Before flashing, back up the existing chip, which keeps a copy of the original data, then confirm the image size matches the chip capacity. Also check the revision printed on the motherboard, because a dump from another revision may not boot.
