BIOS image archive for the MSI MS-7770 desktop motherboard, version 1.0 of the board. MS-xxxx is MSI's own board numbering, normally printed near the PCI slots or on the PCB edge. A dump like this is used to recover a board with a corrupted firmware by writing the SPI flash with an external programmer such as a CH341A. Read and save the original chip contents first, and confirm the image size equals the chip capacity, since an image of the wrong size will not fit or boot.
