Apple boardview for the J134 project, board 820-00597 revision 05, with DVT in the name indicating a design validation test build, stored in .BERD format inside a RAR archive. Apple logic boards carry an 820-xxxxx number on the PCB, and the suffix shows the revision. BRD-style files open in viewers such as FlexBV or OpenBoardView, where you can locate components, follow nets and find test points. Because DVT boards may differ from production units, confirm the number and revision against your board.
