Boardview for the MSI G41M-P26 motherboard, board number MS-7592, revision 1.0, packed in RAR. MSI uses MS-xxxx codes for its own boards, printed on the PCB. After extraction, a viewer such as OpenBoardView or FlexBV shows component placement, nets and pads, which helps when isolating shorts or measuring rails. Note that this is the 1.0 revision; the same model also exists in later revisions such as 5.3, so check the PCB marking carefully before trusting any part location.
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 @boardview. Enginerys does not host this file.
