Working BIOS for the Intel DG31PR desktop motherboard, compressed in a 506 KB RAR archive. No revision or chip information is given in the name, so check the image inside before flashing. A dump like this is used to revive a board with corrupted firmware by writing the SPI or firmware hub chip with a programmer. Before you erase anything, read and save the original contents, confirm the board model printed on the PCB matches, and make sure the image size corresponds to the capacity of the installed flash chip.
