ZIP archive of 4.15 MB that, going by its generic name, holds a BIOS image together with embedded controller firmware. The name gives no device, brand or board number, so the contents must be identified before use. Laptops with a separate EC chip need both images correct, and a wrong EC file can leave the keyboard, charging or power-on dead. Look inside for model strings, compare them with the board number on the PCB, read both original chips with a programmer first, and confirm each image matches its chip size.
