BIOS and EC firmware set for a board identified only as Y116A revision 1.2, marked as working. The name gives no brand or laptop model, so identification has to rely on the Y116A marking printed on the motherboard. The archive should hold the system BIOS image along with embedded controller firmware, which handles power-on, battery charging and keyboard functions. Before programming with a CH341A or similar tool, back up the original chips and confirm that each file size matches its target flash 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.
