11. Chassis intrusion header
This header is for a chassis-mounted intrusion detection sensor or switch.
Connect one end of the chassis intrusion sensor or switch cable to this
header. The chassis intrusion sensor or switch sends a high-level signal to this
header when a chassis component is removed or replaced. The signal is then
generated as a chassis intrusion event.
12. Clear CMOS header
The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM
in the CMOS, which contains the date, time, system passwords, and system
setup parameters.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about
5-10 seconds.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to
re-enter data.
DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or
placing a jumper cap will cause system boot failure!
If the steps above do not help, remove the onboard button cell battery and short the two
pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button
cell battery.
13. COM Port header
This header is for a serial (COM) port. Connect the serial port module
cable to this header, then install the module to a slot opening at the back
of the system chassis.
14. DMIC header
The DMIC header is for connecting the digital microphone module used in
All-in-One chassis.
15. Front panel audio header
This header is for a chassis-mounted front panel audio I/O module that
supports HD audio standard. Connect one end of the front panel audio
I/O module cable to this header.
We recommend that you connect a high-definition front panel audio
module to this header to avail of the motherboard's high-definition
audio capability.
