BIOS dump for the Acer Aspire M5-481G in the version with a discrete GPU, on Quanta motherboard DA0Z09MBAE0 revision E. The RAR is 1.05 MB, and the GPU note means it should not be used on integrated-only boards. Quanta assigns DA0-prefixed codes like this, so verify the number and revision printed on the PCB. Technicians write such images to the SPI chip with a programmer to repair corrupted firmware; read and archive the original first, and confirm the file size equals the chip capacity before flashing.
