BIOS image for the Gigabyte GA-Z170M-D3H DDR3, revision 1.0, packed in a 4.34 MB RAR file. Gigabyte often fits these boards with main and backup BIOS chips, so check which chip needs reflashing before you start. A hardware SPI programmer lets you restore a corrupted image when the DualBIOS recovery fails. Read and archive the original contents first, confirm the DDR3 variant and revision on the PCB, and make sure the file size matches the chip's capacity.
