Audio Configuration
CD-ROM Audio-In Connector: CDIN
The CD-IN connector is used to attach an audio cable to audio devices
such as CD-ROMs, DVD-ROMs etc.
Front Audio Connector: AUDIO
If your case front panel has audio ports, you can connect them to the Front Audio Header of this
mainboard. First, you must remove the jumper caps on this header and then attach the cables
from the front panel to the pins on this header. You can use both the front audio panel and back
panel audio simultaneously. If you are not using front panel audio ports, leave the jumper caps
on the header pins (Note: pins 5-6 and 9-10) to avoid problems with the back panel audio ports.
The following steps explain how to reset your CMOS
configurations when you forgot a system password.
