BIOS image for the Gigabyte GA-B85M-DS3H motherboard, version 3.0 board, sized for a 4MB flash chip and stored in a RAR archive. Technicians write such dumps with an SPI programmer when a board fails to POST after a corrupted update or when replacing the BIOS chip. Many Gigabyte boards carry dual BIOS chips, so identify which one you are flashing. Save a read of the original chip first, confirm the board revision matches, and make sure the image size equals the chip capacity.
