Archive of 660 KB for the Gigabyte GA-B85M-D3V, a micro-ATX board using the Intel B85 chipset for Haswell-generation processors according to the model name. The contents are not identified in the name and no revision is given, so check the extracted files first. If it is firmware, it would be written to the SPI flash with a programmer such as a CH341A; boards of this generation include an Intel ME region, so dump the original chip first to keep the board-specific data and confirm the image size equals the chip capacity. Match the PCB revision before use.
