Backup BIOS image for the Intel DQ67OW desktop board, supplied as a 4.32 MB RAR archive. DQ67OW is an Intel Q67-chipset board, and this dump was most likely read straight from a working board's SPI flash. Technicians use a backup like this to revive a board with corrupted firmware by writing it with an external programmer. Save the current chip contents before writing anything. A dump taken from another board may carry that board's serial and MAC data, so review those fields afterwards.
