BIOS archive for the Acer Aspire 471 series on the Quanta DA0ZQXMB8E0 board, project ZQX at revision E, packed as a 3.44 MB RAR. No version or chip details appear in the name. A clean dump like this is written to the SPI flash with a programmer to fix black screen, boot loop or failed update symptoms. Quanta designed this mainboard for Acer, as shown by the DA0 numbering. Match the full board code on the PCB, read the original chip twice as backup, and make sure the image matches the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
