Schematic for the MSI MS-7C91 desktop motherboard at revision 1.0, provided as a PDF inside a 2.46 MB RAR archive. MSI numbers its desktop boards in the MS-7xxx series and prints the revision on the PCB, which must match this file. The diagram serves for tracing power rails, testing the power-on sequence and identifying components linked to a short or a no-boot fault. It pairs naturally with the revision 1.0 boardview for this board when locating parts physically.
