Circuit schematic for the Jetway I405 motherboard, revision 5.0, supplied as a 592 KB PDF. It is useful when diagnosing a board that will not power on or post, because the pages show how standby and main voltages are generated, where the CPU regulator gets its enable signals, and how the BIOS chip and super I/O connect. Open it in any standard PDF viewer and use text search for net names. Check that the PCB is marked revision 5.0 before comparing component placement or values.
