MSI MS-7246 motherboard schematic whose name carries 10, probably revision 1.0. It is a 1.07 MB PDF. Boards numbered MS-7xxx come from MSI's desktop range. The diagram helps technicians map voltage regulators to their rails, verify connector pinouts and the BIOS chip circuit, and locate measurement points for troubleshooting. Other MS-7246 editions marked 21, 2B and 2-2 exist, so read the revision silkscreened on the board to make sure you use the matching document.
