Acer 471G firmware package for a Quanta-made mainboard numbered DAZQSAMB6E1, containing both the system BIOS and the EC (embedded controller) firmware according to the name. The DA-prefixed number follows the Quanta pattern, where the ZQS part identifies the project and the trailing characters encode the revision. Technicians use such a set to reprogram the SPI BIOS chip and the keyboard controller after corruption with an external programmer. Read and save the original chips first, and confirm the board number on the PCB matches before writing anything.
