Archive for the MSI MS-7246, a 5.64 MB ZIP whose name gives only the board number. Contents and revision are not specified, so inspect the files after extraction; a schematic, boardview or BIOS dump are the usual possibilities. MSI designates its own desktop motherboards with MS-7xxx codes. Such material is used to follow rails, locate test points and isolate shorts. Compare the revision printed on the board, and keep a backup of the original flash chip before writing anything to it.
