BIOS for a board identified only as CYBAF-10-H61, suggesting an Intel H61 chipset desktop motherboard, packed in a 2.16 MB RAR. The name gives no brand, version or chip details.

Compare the identifier printed on your PCB first, save a backup of the existing chip contents, and ensure the image size equals the chip capacity before flashing.
