RAR package of 583 KB for the ASUS Maximus VI Formula motherboard. Only the model is stated, so the revision and the exact file type inside need to be checked after unpacking. A boardview from it is used in FlexBV or a similar viewer to find components, follow power paths from the VRM and choose measurement points while hunting a short. Compare the revision marked on the PCB with the extracted material before relying on any component location.
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.
