MSI MS-6514 archive, a ZIP of only 478 KB. Apart from brand and model number, the file name offers nothing about revision or contents, so it should be opened and checked. The small size points to a BIOS image or a short document, but this is not stated. MS-6xxx codes are MSI's own board identifiers. Before reflashing any firmware found inside, read the original chip with a programmer and save it, and check that the revision on the board matches the data.
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.
