9) ATX Power Supply Connector (20-pin block ATXPWR)
This connector connects to an ATX power supply. The plug from the power supply
fits in only one orientation because of the different hole sizes. Find the proper
orientation and push down firmly making sure that the pins are aligned.
IMPORTANT:
Make sure that the ATX power supply can supply at least 10mA
on the +5-volt standby lead (+5VSB). You may experience difficulty in turning
the system ON if the power supply cannot support the load. For Wake-On-LAN
support, the ATX power supply must supply at least 720mA +5VSB.

8) Internal Audio Connectors (4-1 pin CD_IN, MODEM)
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM. The MODEM connector allows the onboard audio to
interface with a voice modem card with a similar connector. It also allows the
sharing of mono_in (such as a phone) and a mono_out (such as a speaker) between
the audio and a voice modem card.
