Firmware image for a laptop mainboard numbered DA0WJ5MB6E0, revision E, packed in a 2.20 MB RAR. The DA0 prefix and MB6E0 suffix follow the Quanta ODM scheme, where WJ5 is the project code; the laptop brand is not stated in the name. Such a dump is typically flashed to the board's SPI chip with an external programmer to recover a corrupted BIOS. Before writing, back up the existing contents, check that the board number and revision on the PCB match, and confirm the file size equals the chip capacity.
