BIOS and EC firmware package for the Acer Aspire A314-22 notebook, board DA0Z8EMB8C0, distributed as a RAR archive of about 3.82 MB. The board number follows the Quanta format, indicating Quanta built this mainboard for Acer. Including the embedded controller firmware is useful because a corrupted EC image can cause no power, charging or keyboard faults even when the main BIOS is fine. Dump and keep the original chips before programming, and verify that each image matches the size of the target flash device.
