BIOS image set for the ECS H81H2-M4 desktop board, version 1.0A, compressed into a 3.63 MB RAR. The model belongs to the ECS H81 family for Intel Haswell-era systems, often found in OEM machines. Before flashing with a programmer, confirm the 1.0A version marking on the PCB. Also check whether the dump contains a full image with the ME region, and that its size equals the SPI chip. Keep a backup of the original contents in case the replacement does not boot.
