Archive for the Gigabyte GA-H61M-DS2 motherboard, 3.39 MB in RAR form, with no revision or content type given in the name. The H61 chipset supports second and third generation Intel Core LGA1155 processors. It may contain a BIOS image or service files, so check before use. Gigabyte lists the board revision on the PCB, and BIOS images differ between revisions, so match it. When reflashing the SPI chip with a programmer, save the original contents and verify the image size.
