MSI MS-7349 revision 1.1 files in a RAR archive of 1.39 MB. The contents are not described in the name, but the size fits a schematic PDF or a BIOS dump. Check that the board is marked revision 1.1, because routing and parts can change between revisions. MS-7xxx is MSI's desktop motherboard code. Use a schematic to trace power rails and test points. For firmware, read and save the original SPI chip first and confirm the image size matches the chip.
