10. NLX Power Supply Connector (20-pin NLX_PWR)
This connector connects to an NLX power supply. The plug from the power
supply will only insert in one orientation because of the different size holes. Find
the proper orientation and push down firmly making sure that the pins are aligned.
IMPORTANT: Be sure that the NLX power supply can deliver at least
720mA on the 5volt standby lead (+5VSB). You may experience difficulty in
powering on your system without this specification.
