ASUS F2A85-V PRO motherboard data in a 281 KB RAR archive; the document type is not stated. The board uses the AMD A85X chipset for FM2 socket APUs. Such repair packs typically carry a boardview, which a tool like OpenBoardView or FlexBV renders with part outlines, nets and probe points for checking shorts on the APU VRM or tracing missing standby voltages. Inspect the extracted file and match the PCB revision against it before working from the layout.
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.
