BIOS ROM in a ZIP archive for the H61M-VS3 desktop motherboard, firmware version 1.70 according to the name. The H61M-VS3 is an ASRock micro-ATX board built on the Intel H61 chipset, although the file name itself states no brand. A ROM like this is used to reflash the SPI BIOS chip with a programmer when the board no longer posts or a flash has failed. Read and keep the original contents first. Make sure the image size equals the chip capacity and that your board is the same model and revision.
