Analog Audio Input Header
If you have installed a CD-ROM drive or DVD-ROM drive, you
can connect the drive audio cable to the onboard sound system.
When you first start up your system, the BIOS should
automatically detect your CD-ROM/DVD drive. If it doesn’t, enter
the Setup Utility and configure the CD-ROM/DVD drive that you
have installed. On the motherboard, locate the 4-pin header CD1.
