MSI service archive in ZIP format for board MS-16W11, version 1.1, totalling 46.0 MB. MSI uses MS-xxxx numbers for its own laptop and desktop designs, printed on the PCB with the revision. The name does not list contents, but the size suggests a schematic, boardview or firmware set, possibly several. Extract and identify each file before use. Check that the board version on the PCB is 1.1, and for any BIOS image, back up the original chip and compare sizes before programming.
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 @azvoltagemap. Enginerys does not host this file.
