Very small RAR archive, only 2.31 KB, labelled with code 08627 and suffix SA and no other information. The project number follows the Wistron pattern. At this size the archive can hold little more than a tiny firmware fragment, configuration data or a text note, so its usefulness should be checked on extraction. Do not flash anything from it without confirming the board marking, the intended chip and its capacity, and always keep a backup read of the original chip contents first.
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.
