MSI MS-6714 files for version 100, revision 100, in a 532 KB zip archive. This appears to be the early 1.00 issue of the board, and other revisions of the same MS-6714 design exist, so the version marked on the PCB must match before you rely on part locations or firmware. The name does not say what is inside; extract it and identify any schematic or ROM image. If flashing, read the original chip with a programmer first and confirm the image size equals the chip capacity.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
