BIOS image for the Gigabyte GA-Z170-D3H motherboard, revision 1.0, an Intel Z170 ATX board. Held in a 5.17 MB RAR, it serves for reprogramming the SPI flash with an external programmer after a bad update or when the board stays dead with a corrupted firmware. Gigabyte frequently fits main and backup BIOS chips, so confirm which one you are working on. Dump and keep the existing contents before writing, and make sure the image size matches the chip capacity.
