Firmware set for MSI notebook board MS-16H4, also listed under the variant number MS-16H41, supplied as a 13.0 MB RAR. The name says it contains an 8 MB BIOS image together with the EC (embedded controller) firmware. The EC handles power-on, charging and keyboard functions. Write both with an external programmer when a board shows no power or is stuck after a failed update. Back up the original BIOS and EC chips before flashing, and check that the 8 MB image matches the fitted SPI 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 @biosarchive. Enginerys does not host this file.
