Dual BIOS package for the Gigabyte GA-H61M-S2PH motherboard, version 1.0 per the name, in a 5.80 MB RAR archive. Gigabyte DualBIOS boards carry a main and a backup flash chip, so the archive likely holds images for both. They can be written with an SPI programmer when both chips are corrupted and the board fails to start. Note which image belongs to which chip, back up each original before writing, and confirm every file matches its chip capacity.
