CD Header/Auxiliary Audio
Header
A 4-pin CD header (CD in) and an
Auxiliary header (Aux.) are lo-
cated on the motherboard. These
headers allow you to use the on-
board sound for audio CD play-
back. Connect the audio cable
from your CD drive to the header
that fits your cable's connector.
Only one CD header can be used
at any one time. See the tables at
right for pin definitions.
