Layout file for the earliest listed revision of the MSI MS-7522, rev 10, delivered as an 828 KB ZIP. Revision 10 corresponds to the 1.0 marking typically silkscreened on MSI boards; later revisions such as 2.0 have their own boardviews, so check your PCB before using it. A boardview viewer such as OpenBoardView opens the extracted file and lets you highlight nets, search reference designators and see which pins share a signal. That makes it useful for locating test points and isolating a component that shorts a rail.
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.
