Gigabyte BIOS archive for the GA-H61M-USB3-B3 motherboard, revision 2.0, in a 1.52 MB RAR. The H61 tag refers to the Intel H61 chipset. Gigabyte boards of this generation often use dual BIOS chips, and a corrupted image can be restored with an SPI programmer when the backup recovery fails. Gigabyte sometimes changes the flash chip and firmware between board revisions, so confirm the rev 2.0 marking near the PCIe slots, back up the existing chip and match image size to chip capacity.
