Acer desktop motherboard BIOS for the H61H2-AM board, version or revision V1.1, compressed in a 2.26 MB RAR. The H61 chipset in the name points to an LGA1155 platform used in Acer OEM systems. The image is meant for the SPI flash chip and is usually written with an external programmer when the system no longer posts. Check the board label and revision on the PCB, keep a backup of the original chip and confirm the extracted image size fits the chip.
