MSI MS-7072 materials in a RAR archive of 2.56 MB. The name does not reveal the revision or what kind of files are included, so inspect the contents with WinRAR or 7-Zip before use. Typical repair packages contain schematics for tracing rails and signals, boardviews for locating components and test points, or BIOS dumps for SPI reflashing. The MS-7xxx code is MSI's desktop board numbering; check that the PCB revision matches and keep a backup of the original firmware before flashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
