Boardview for the MSI PRO Z690-P DDR4 desktop motherboard, the DDR4 memory variant of this Intel Z690 board, packed as a 100 KB ZIP archive. A boardview lets a technician locate components, test points and nets on the PCB, follow a signal from the CPU socket or VRM to its connector, and check which parts share a shorted rail. Unpack it and open the file in a viewer such as OpenBoardView, FlexBV or a similar tool, and confirm the board model and revision printed on the PCB match before trusting part positions.
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 @cynetitsolution. Enginerys does not host this file.
