Very small RAR archive, 81.5 KB, named R9600L with no brand, revision, board number or file type indicated. At this size it probably holds a compact firmware file, a configuration file or a short text note rather than a schematic. Extract it with 7-Zip or WinRAR to determine the actual content. A separate file for the same code tagged V10 exists, so compare the two before choosing one. Match any identifiers against the hardware, and back up the device memory before writing anything to it with a programmer.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
