Firmware archive named only V301, which may be a version number; no brand, model or board is given, so the purpose has to be worked out from the contents. At 2.18 MB it may hold a small SPI image or an EC firmware. Look inside for identifiers and compare them with the board markings. Never write it blind: save the original chip contents with a programmer first and check the file size against the target chip.
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 @bios_files_Request. Enginerys does not host this file.
