Acer desktop BIOS for the H61H2-AM board, a 4 MB image according to the name, shipped in RAR form. The i3 tag likely refers to the Core i3 system configuration. H61H2-AM boards are ECS-built Intel H61 designs used in Acer desktops. Flash it to the SPI chip with a hardware programmer when the machine will not post after a failed update.
