BIOS for the MSI H81M-S04 desktop motherboard, board number MS-7817, version 6.1, packed in a 5.90 MB RAR archive. The board uses the Intel H81 chipset, as its name indicates, and MS-7817 follows MSI's own board numbering. Use the image to restore corrupted firmware by flashing the SPI chip with an external programmer when the board will not post. Check that the PCB is version 6.1, back up the original chip, and compare the chip capacity with the image size.
