MSI BIOS archive, 4.24 MB, for the H61M-P23 (B3) motherboard, MSI model code MS-7680. MSI prints its MS-xxxx code on the PCB, which is the reliable way to identify the board, and B3 refers to the revised Intel H61 chipset stepping. The image restores a board with corrupted firmware through M-Flash or external programming of the SPI chip. Check the MS-7680 marking and PCB version, back up the original contents and confirm the dump size matches the flash chip capacity before writing.
