Internal Sound Connections
If you have installed a CD-ROM drive or DVD-ROM drive, you
can connect the drive audio cable to the onboard sound system.
On the mainboard, locate the two 4-pin connectors CD_IN1 and
CD_IN2. There are two kinds of connectors because different
brands of CD-ROM drives have different kinds of audio cable
connectors. Connect the cable to the appropriate connector.
