Zip archive holding firmware named for MSI board MS-16W21, version 101. At only 46.8 KB compressed it is far smaller than a typical system BIOS, so it may be an EC firmware or a highly compressible image; check the contents after extraction. MS-16W21 uses MSI's own board numbering. Before programming, identify the target chip, confirm the image size equals its capacity, and save the original contents so the board can be restored if the file proves to be the wrong one.
