Verified BIOS dump for the Acer E5-471 series laptop, made on Quanta board DA0ZQ0MB6E0 revision E, delivered as a 5.44 MB RAR. The name states it is fully working. Quanta numbering uses the DA0 prefix plus a project code, here ZQ0, with the closing characters giving the board revision. Program the image to the SPI BIOS chip with an external programmer after saving the existing contents, and verify that the chip capacity and the revision letter on the PCB agree with this file.
