Jetway 845CA motherboard circuit diagram, a 570 KB PDF; the name gives no revision. It is useful for following voltage rails from the power connector through the processor regulator, checking the memory supply, and tracing reset, clock and BIOS chip connections when a board fails to post. Any PDF viewer can open it. A separate revision 5.0 drawing for this model also exists, so compare the revision marked on the PCB and the layout of major parts to make sure this version matches the board on the bench.
