Archive of 203 KB titled P5KPL-SE, an ASUS desktop board model, in RAR format with no further detail in the name about whether it holds a boardview, schematic or firmware. Extract it and identify the payload by extension before use. If it is a boardview, it lets a technician find component locations, follow nets between pins and look up test points while diagnosing a short or no-power fault. Match the board revision silkscreened on the PCB to the version in the file, as layouts can shift between revisions.
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.
