Intel D845GRG desktop board BIOS, stored as a 512 KB binary image. The name carries only the model number, without version, revision or tested status. The file is meant to be programmed directly into the board's flash chip to recover from corrupted firmware. Check the chip type and whether it is socketed, make sure your programmer supports it, save the original contents before erasing, and confirm the chip size equals 512 KB so the image fits without truncation.
