Boardview for the MSI B560M-A PRO desktop motherboard, MSI model code MS-7D20, revision 1.0, packed as a 1.29 MB RAR. MSI prints the MS-xxxx code and revision on the PCB, usually near the slots, so check both before working from this layout. The file shows component placement and net names, helping to trace VRM rails, locate the SPI BIOS chip, follow signals to the LGA1200 socket area and pin down shorted capacitors. It is opened with boardview viewers such as FlexBV or OpenBoardView once extracted.
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.
