ZIP archive of 7.73 MB for the MSI MS-7250 motherboard; the name lists no revision or contents. A schematic is likely given the size, but check what is inside before relying on it. MSI uses the MS-7xxx scheme for its own desktop boards. A revision 2.2 boardview for this model also exists, so match revisions between files and against the PCB silkscreen. Use the documents for tracing rails and test points, and save the original flash before writing any firmware.
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.
