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.
ExceptwhenclearingtheRTCRAM,nevershort-circuittheCLRTCjumper.Shortingthe
CLRTCjumperwillcausesystembootfailure!
• 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.
• YoudonotneedtocleartheRTCwhenthesystemhangsduetooverclocking.For
systemfailureduetooverclocking,usetheCPUParameterRecall(C.P.R.)feature.
Shutdownandrebootthesystem,thentheBIOSautomaticallyresetsparameter
settingstodefaultvalues.
• Duetochipsetbehavior,ACpoweroffisrequiredtoenableC.P.R.function.Youmust
turnoffandonthepowersupplyorunplugandplugthepowercordbeforerebooting
thesystem.
1.1.7 Jumpers
1. Clear RTC RAM (2-pin CLRTC)
ThisjumperallowsyoutocleartheRealTimeClock(RTC)RAMinCMOS.Youcan
cleartheCMOSmemoryofdate,time,andsystemsetupparametersbyerasingthe
CMOSRTCRAMdata.TheonboardbuttoncellbatterypowerstheRAMdatain
CMOS,whichincludesystemsetupinformationsuchassystempasswords.
