Boardview file in FZ format for the ASRock A320M-HDV motherboard, revision 1.04. A technician uses it to find components by reference designator, follow nets between chips and locate test pads when measuring voltages or tracking down a shorted rail. FZ boardviews open in OpenBoardView, FlexBV and similar programs. The revision printed on the board should read 1.04, because other revisions of this model may have different placement, and mismatched data can send you to the wrong component.
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 @boardviews. Enginerys does not host this file.
