Firmware archive for a Quanta motherboard numbered DA0BD5MB8D0, revision D, holding an 8MB BIOS image. The name gives no laptop brand or model, so identify the machine from the board silkscreen rather than from the case label. The DA0 prefix with MB marks a Quanta mainboard, and the BD5 project code identifies the design. Before flashing with a CH341A or similar SPI programmer, back up the existing chip, verify the revision letter matches, and make sure the 8MB image fits the installed flash part.
