Firmware dump for a Quanta motherboard numbered DA0ZS8MB8E1, revision E, compressed as a 7.21 MB RAR. The name does not give the laptop brand or model, so identify the system from the ZS8 project code on the PCB. Quanta's DA0 prefix, three-character project code and MB marking form the board number found on the silkscreen. Before programming, back up the original SPI chip with a programmer. Also confirm the dump size matches the flash capacity and that your board is revision E.
