BIOS firmware for a laptop mainboard numbered DAG7CMB16E1, revision E, a Quanta design going by the DA-prefixed numbering scheme that Quanta prints on its boards. The name gives no laptop brand or model, so identify the target from the PCB silkscreen itself. The ZIP archive is 5.58 MB and should contain the SPI flash image used to recover a board with corrupted firmware. Back up the original chip with a programmer before writing, and check that the file size matches the capacity of the installed flash chip.</description>
