Boardview for the Apple MacBook logic board 820-00239, a compact 136 KB RAR holding a BDV-format layout. Apple's 820 prefix identifies the logic board number, so confirm the marking on the PCB before use. The file opens in boardview programs like OpenBoardView or FlexBV and shows component positions, pin connections and net names. Paired with the matching schematic, it lets you locate a part referenced in the diagram, find test points, follow power rails and pinpoint a shorted capacitor.
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 @pkbiosbdv. Enginerys does not host this file.
