BIOS and EC firmware package for the MSI S20 notebook, whose mainboard follows MSI's own numbering as MS-1161. Both the system BIOS image and the embedded controller firmware come in a 4.06 MB RAR archive, which helps when a board will not power on, ignores the keyboard or has trouble charging. Before flashing, open the archive and identify which file belongs to which chip, read and save the existing contents with an SPI programmer, and make sure each image size matches the capacity of its target 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.
