BIOS firmware for the ASUS E402NA laptop, board revision 2.3, marked as tested and working. The RAR archive is 10.5 MB, so it likely contains a full chip image plus related files. Such a dump is used to revive a board with corrupted firmware by writing it to the SPI flash chip with a hardware programmer. Check that the revision on your PCB is 2.3, confirm the image size matches the chip capacity, and read and save the original contents first, as they carry serial and MAC data unique to the machine.
