Circuit diagram in PDF for the Foxconn 945P01 mainboard, an Intel 945P chipset design according to the model code, indexed under the ECS brand. No revision appears in the file name, so check the version marked on the board first. Useful for following VCORE regulation, memory and MCH supply rails, clock generation and the power-on handshake between the super I/O and south bridge, as well as identifying what loads a shorted rail. Opens in any ordinary PDF viewer; compare component values with the physical board when options differ.
