Boardview archive for a board labelled G35-MB-C, delivered as a 398 KB RAR containing a BDV-type file, which is a boardview format. The name does not give the brand, so match the full board number on the PCB before use. Boardview data maps every component and net on the board, making it practical to find test points, trace which parts connect to a shorted rail, and locate small passives around power controllers. Open it in software that supports BDV files, such as OpenBoardView or FlexBV, and confirm the revision matches your 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 @cyberlanelectonik. Enginerys does not host this file.
