Compressed RAR archive of about 185 KB labelled for the ASUS UX32LA-LN motherboard, revision 2.0. The name does not say what is inside, but an archive this small for a single board revision usually holds a boardview or a compact BIOS-related file rather than a full schematic set. Open it and check the contents before use. Whatever it holds, confirm that the revision silkscreened on the PCB reads 2.0, because layouts and component placement often change between revisions of the same model.
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.
