BIOS firmware package for the MSI Z68A-GD80 (B3) desktop motherboard, built around the Intel Z68 chipset, supplied as a 4.28 MB RAR archive. The B3 suffix in the name refers to the board variant using the revised B3 chipset stepping. Technicians use such an image to recover a board with a corrupted BIOS by writing it to the SPI flash with a programmer like the CH341A. Before flashing, read and save the original chip contents, confirm the model and PCB revision printed on the board, and check that the image size matches the flash chip capacity.
