Firmware set for MSI board MS-16W21, containing both the system BIOS and the EC (embedded controller) firmware, packed in a RAR of about 6.29 MB. MSI designs its own boards and uses the MS-xxxxx numbering, with the trailing digits usually indicating the board revision. The EC image handles power-on, charging, keyboard and fan control, so a corrupt EC can cause no-power faults. Flash each image to its proper chip with a programmer, matching sizes, and back up the original contents before writing.</nowiki>
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 @biosarchive. Enginerys does not host this file.
