Second copy of a BIOS dump for the Intel DG31PR board, 512 KB in size, distinguished only by the (2) suffix, so the version difference from other DG31PR files is unknown. Comparing both images in a hex editor can reveal which one suits your board. The binary is intended for writing to a 4 Mbit SPI or FWH flash with a programmer. Back up the existing chip, confirm the board model, and verify the image size matches the chip.
