BIOS image for a desktop board named CIH81M with the ECS-style code H81H3-LM, version 1.0, based on the Intel H81 chipset; no brand is stated in the name. Boards of this kind are common in OEM and budget systems, so check the silkscreen to make sure the model codes match. Use it to recover a board with corrupted firmware by writing the image to the SPI flash with a programmer. Read and save the original contents first, and check that the image size matches the chip capacity before writing.
