Intel D915GUX motherboard BIOS stored as a 512 KB binary image. Nothing else is encoded in the name: no firmware version, revision or note about whether it was tested. Such files serve for off-board recovery when a failed flash leaves the system without video or POST, written with an external programmer that supports the chip on the board. Read and keep a copy of the existing chip first, compare the chip capacity with the 512 KB image, and confirm the board silkscreen really says D915GUX.
