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.
