Release 1.40 of the B75M-DGS BIOS, dated 12.27.2013 and marked evropa, apparently the European edition and the newest of the versions listed. The ZIP measures only 3.66 KB, which is too small for a full motherboard ROM, so treat its contents with caution and verify them before programming. Desktop board firmware is normally restored by flashing the SPI chip with an external programmer. Confirm the PCB model, read and save the current chip, and compare image size with the chip capacity.
