ZIP archive, roughly 645 KB, for the DG965RY, an Intel desktop board model name based on the G965 chipset. The name does not state revision or contents, so unpack it to see whether it is a BIOS image or documentation. Boards of this era often use smaller flash chips, so verify the dump size matches the actual part before programming. Read and save the original contents with an SPI or LPC-capable programmer as appropriate. Check the AA revision label on the board as well.
