Duplicate-named BIOS dump for the Intel D915GUX board, 512 KB in size; the (1) suffix only distinguishes it from another file of the same model. Whether its contents differ from the other copy is not stated, so a quick binary comparison helps decide which to use. The image is meant for writing directly to the board's firmware chip with a programmer during repair of a corrupted BIOS. Back up the current chip, check the part number and capacity, and verify the write afterwards.
