BIOS image for the Gigabyte GA-B85M-D2V-SI desktop motherboard, revision 3.0, with a 4 MB flash size noted, archived in RAR form. B85 boards of this generation often carry small SPI chips, and the image restores a board that will not post after a failed update or corruption. Write it with a programmer such as a CH341A, matching the board revision marked on the PCB. Read and keep the existing chip contents for MAC data, and confirm the image is exactly 4 MB to suit the installed chip.
