1. Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data of the system
setup information such as date, time, and system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two pins.
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.
NOTE: If the steps above do not help, remove the onboard battery and move
the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS,
reinstall the battery.

2. Chassis intrusion header (4-1 pin_CHASSIS)
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 connector. The
chassis intrusion sensor or switch sends a low-level signal to this connector
when a chassis component is installed. The signal is then generated as a chassis
intrusion event.
