Firmware for the Acer Aspire 5570 marked 945, most likely referring to the Intel 945 chipset family, supplied as a 526 KB 7z archive that opens in 7-Zip. The name gives no board number or version, so identify the motherboard from the PCB before use. The dump is meant for restoring a corrupted BIOS flash with an external programmer. Read and keep the original contents first, and make sure the extracted image matches the chip capacity.
