BIOS firmware for the MSI H61M-P20 (G3) desktop motherboard, board MS-7788 version 1, in a 2.94 MB RAR. MSI prints the MS- number and version on its boards, and the G3 variant should match the board in hand. Such an image can be flashed through MSI's update tool on a working board, or written to the SPI chip with a programmer when the board no longer posts. Read and keep the original chip contents first, and confirm the file size matches the flash chip capacity before writing it.
