Optional CD-ROM Audio-in (CN9)
Use the audio cable enclosed with your CD-ROM
disk drive to connect the CD-ROM to your
mainboard. This will enable your CD-ROM's audio
function.
Infrared Connector (CN10)
If you enable the COM2 Mode in BIOS's Integrated
Peripherals menu the COM2 port will support IR
functions. (See section 3-4)
CASE/CPU Cooling Fan Connectors
(
CN12/CN16)
These added connectors allow the fan to draw
their power from the mainboard instead of the disk
drive connector.
The board's management extension hardware is
able to detect the CPU and system fan speed in
rpm (revolutions per minute). These connectors
supports 3-pin cooling fans with minimum of 3500
RPM. The wiring and plug may vary depending
on the manufacturer. On standard fans, the red
is positive (+12V), the black is ground, and the
yellow wire is the rotation signal.
