Chapter 2: Motherboard information
2.5 Jumpers
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 jumper (4-1 pin CHASSIS)
This connector 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 high-level signal to
this connector when a chassis component is removed or replaced. The signal
is then generated as a chassis intrusion event.
Move the jumper cap to pins 1-2 when you intend to use the chassis intrusion
detection feature.
