RAR archive with a BIOS image for Quanta board DAG3KMB2CA0, revision A, with the name also carrying a BID code 088F4 that most likely identifies the board or BIOS ID. No laptop brand is stated, so confirm the board label rather than relying on a model name. Quanta boards use the DA0 or DAx prefix plus project code G3K and MB. Flash the extracted image to the SPI chip with a programmer after saving the original contents, and check that the file size equals the chip capacity before writing.
