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.

7. 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.
