RAR archive of about 2.7 MB holding a flash dump for the Mediastar MS-R120; the exact file list and firmware version inside are not stated in the name. A dump like this is normally programmed into the device's flash memory chip with an external programmer when the unit no longer boots or its software is corrupted. Extract the archive, check the image size against the capacity of the chip on your board, and always read and back up the existing contents before writing anything to the memory.
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.
