Boardview for MSI desktop motherboard MS-7B22 at revision 1.0, compressed in a 1.36 MB RAR archive. MSI uses the MS-xxxx code for its own boards, and the revision is usually printed near the PCIe slots or board edge, so check it matches before trusting placement data. A boardview viewer shows every component and net, which helps when tracing VRM phases, locating test points, following BIOS chip signals or isolating a shorted MOSFET or capacitor on a dead board.
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 @BoardSchematic. Enginerys does not host this file.
