RAR archive for the MSI MS-7108 board, 743 KB in size. The name gives only the brand and board number, so the exact contents, whether schematic, boardview or BIOS image, are not stated and should be checked after extraction. MS-7xxx is the numbering MSI uses for its own desktop motherboards. Before relying on any file inside, compare the board number and revision silkscreened on the PCB with the documents, and if a firmware dump is included, back up the original SPI chip with a programmer before writing anything.
