KBC firmware, the keyboard and embedded controller image, for the A720 on Quanta board DA0QU7MB8C0, revision E. The controller handles power-on sequencing, battery charging and the keyboard, so a corrupted image can leave the board dead or unable to start. The file is 4.00 MB, which is unusually large for EC code and may be a full chip read rather than just the controller region; check its contents before use. Match the board revision, then save the original chip before writing with a programmer.
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 @abgm_manutencao_bios. Enginerys does not host this file.
