BIOS image for the ASRock B85M-DGS desktop motherboard, revision 1.01, with the internal file name B85MDGS1 suggesting the board-specific firmware build. The board uses the Intel B85 chipset as its name indicates. Useful for reprogramming a bricked SPI chip with an external programmer such as a CH341A when the board shows no display. Check that the revision printed on the PCB matches, save the existing chip contents before erasing, and confirm the image size equals the flash capacity.
