Dell BIOS dump for the Quanta-built board DA0R09MB6H1, revision H, labelled as a fully working BIOS. DA0 numbers follow Quanta's scheme, the ODM behind many Dell boards. Flash it to the SPI chip with a programmer such as a CH341A, and read and save the original contents first so the board's service tag and other unique data are not lost. Confirm the board number and rev H on the PCB, and check that the image size matches the chip capacity before writing.
