Firmware dump for the Acer Aspire E1-471, tied to the Quanta DAZQSAMB6F1 board at revision F. Delivered as a 2.76 MB RAR archive, it is meant for reprogramming the BIOS SPI chip on a board that will not POST or shows no picture. Quanta board codes start with DA and encode the project and revision, so check the label on the PCB carefully, including the final revision letter. Use a programmer such as CH341A or RT809, read the original chip first, and verify the image length matches the installed flash before writing.
