BIOS firmware archive for the motherboard numbered DAFL8AMB8D0, revision D, with the name pointing to the AMD CPU variant of the board. The DA...MB...0 pattern follows Quanta numbering, so the laptop brand itself is not stated. The 1.46 MB zip should hold an SPI flash image to write with a programmer such as a CH341A. Confirm the board number and revision printed on the PCB, read and save the original chip contents first, and check that the image size matches the flash chip capacity.
