A second copy of a Gigabyte GA-H61M-S motherboard package, a 573 KB ZIP archive identical in size to another entry with the same model name. The name lists no revision or contents, so compare the files after extracting to see whether they differ. For this H61 board the files likely cover a schematic, boardview or BIOS. Use them to trace supply rails and signals, find shorted parts, or reflash the SPI flash after backing up the original. Check the revision on the PCB first.
