Working BIOS dump for the Acer Aspire 5570 on an Intel 945 chipset platform. The 1.00 MB raw binary corresponds to an 8 Mbit flash chip. A sibling file with a LAN tag exists, so this is presumably the version without that LAN-related change. Load it into programmer software, erase the chip, write and verify. Read the original contents before doing anything, and keep that backup safe. Confirm the motherboard matches the 5570 with the 945 chipset before relying on this image.
