BIOS firmware archive for the Gigabyte GA-H61M-S2P desktop motherboard, built on the Intel H61 chipset as the model name indicates. The OK tag in the name suggests the dump was checked and reported working. At 2.82 MB the RAR likely holds an image for the onboard SPI flash. Use it to recover a board with corrupted firmware by writing the chip with a programmer such as a CH341A. Read and save the original chip contents first, and check that the image size matches the flash capacity and the board revision.
