Reference PDF on EC, IO and KBC chips, covering which embedded controller, super I/O and keyboard controller parts need programming with firmware and which work without it. The name gives no laptop model or board number, so it serves as a general guide rather than a schematic for one board. Technicians use such notes to decide whether a replacement EC or KBC must be flashed with a matching dump before fitting. At 170 KB it opens in any PDF reader. Check the exact chip marking on the board against the list before ordering or programming a part.
