BIOS archive for Toshiba Satellite C70D-A and C75D-A laptops using the Quanta motherboard DA0BD9MB8F0 at revision F. The D in the model names indicates the AMD-based variants of these series. Quanta prints the DA0 project code and revision on the PCB, so both should match before the image is written. Technicians use such a dump to revive a board stuck with no display after a corrupted flash; read and keep the original chip contents first and confirm the file size equals the chip capacity.
