Schematic in PDF form, about 1.07 MB, for the ECS 946GZT-AM desktop mainboard. The model name indicates an Intel 946GZ chipset design with integrated graphics. Repair use includes tracing the CPU VRM and memory voltages, checking the ICH standby rails and RTC circuit, following the power button and PS_ON logic, and confirming connector pinouts. Any PDF reader will open it, and searching net names helps move between sheets. ECS models often had several revisions, so verify the version printed on the PCB before relying on values or fitted parts.
