Service files for the ECS H77H2-M3 motherboard, revision A, delivered as a 734 KB ZIP. Like its M4 sibling it is named for the Intel H77 chipset, but the two boards are distinct and their documents should not be mixed. The name does not list the contents, which may include schematics, a boardview or firmware. Use diagrams to follow VRM and memory rails during power faults, and back up the existing SPI flash before writing any firmware. Check the revision on the PCB first.
