A 748 KB ZIP tied to MSI motherboard number MS-6750. Its name states only the maker and the board code, so treat the contents as unknown until extracted; they may be a schematic, a BIOS file or both. MSI uses the MS- prefix for its in-house model numbers, printed directly on the PCB. Before relying on anything inside, compare that print and the board revision. A dump written to the wrong board or without a backup of the original chip can leave the system unable to start.
