Note: Anexternalalphanumerickeyboardisrecommendedfor
runningtheBIOSCMOSSetupUtility.Otherwise,aTouchScreencan
beused.
Plug and Play
TheProcessorBIOSalsohasasetupoptiontosupporttheWindows
runtimeplugandplayutilities.Whenthisoptionisselected,only
devicescriticaltobootareassigned
resourcesbytheBIOS.Device
Nodeinformationisavailableforalldevicestoensurecompatibility
withWindows95.Systemconfiguration informationisstoredinESCD
format.TheESCDdataiscleareduponlossoftheCMOSvoltage.
Advanced Power Management
TheProcessorBIOShassupportforboth1.1and1.2AdvancedPower
Management
(APM).TheversionofAPMdriversloadedinthe
operatingsystembytheuserdetermineswhatspecificationtheBIOS
adherestoo.IneithercasetheenergysavingStandbymodecanbe
initiatedbyakeyboardhotkeysequenceoratime‐outperiodsetby
theuser.
WheninStand‐by
mode,theProcessorBoardreducespower

VESADPMScompliantmonitors.Duringsetup,theusermayselect
whichDPMSmode(StandBy,Suspend,orOff)issenttothemonitor.
Theability
torespondtoexternalinterruptsisfullymaintainedwhile
inStand‐bymodeenablingthesystemtoservicerequestssuchasin‐
comingdataornetworkmessageswhileunattended.Theusermay
alsoselectanykeyboardormouseactivitytotakethesystemoutofthe

thisoccurs,themonitorandIDE

APMisdisabledinBIOSbydefault;therefore,theusermustenable
thisfeature.ThesystemmustbeconfiguredwithanAPMdriverin
