Working BIOS image for the Acer desktop board made by ECS, model H61H2-AD version 1.0, compressed into a 3.10 MB RAR. ECS builds many OEM boards for Acer, and the H61 chipset indicates an Intel LGA1155 platform. Use the file to rewrite the SPI flash with a programmer when the board will not post or the firmware is corrupt. Check that the board label reads H61H2-AD V1.0, compare the image size with the chip capacity and keep a backup of the original contents first.
