PDF schematic for the ECS 945GZ-B2 motherboard, revision B, with the extra marker 3, packed in a RAR archive. This board uses the Intel 945GZ chipset for LGA775 processors. The diagram shows power rails, VRM circuits, clock and reset lines, which helps when tracing no-boot or no-power faults. Open it in any PDF reader. Compare the revision letter printed on the PCB with the schematic before relying on component values or net names.
