LPC power/ground (v1.4 - v1.5)

There's no visual method to distinguish a v1.5 from a v1.4.
Xbox v1.5 has power and ground disconnected from LPC.
So you will have to measure if pin 2 (ground) on the LPC-bus is connected to the ground plane (a screw, for example) or not

Use a multimeter to check if pin2 (red point on images) is connected with ground (screw plate for example).
If you prefer you can also measure 3.3v (LPC pin 9) (xbox must be ON) ... it's dead on a v1.5.

*NOTE* Don't just assume you have a v1.5 because you have a new Xbox. There are very few v1.5 xboxes (we don't have exact data about this - but probably only produced on a few production lines in August 2003 (as testrun, production fault, ... we don't know). As far as we know MS produced the v1.4 again on all lines after that. Do the test above to make sure wich version you have. You most probably have a v1.4!
