Small zip archive tied to board number 08224-1, a numbering pattern used by the ODM Wistron, with the suffix DR1 in the name. The name does not say what the archive holds, so it could be a schematic, boardview or firmware for that board; open it and check the contents before relying on it. Wistron board numbers are printed on the PCB silkscreen, and the number and revision on your board must match before you use any file from this set for diagnosis or flashing.
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 @schematicslaptop. Enginerys does not host this file.
