Themainboarddesign supportsSoftwarePowerOff Controlfeaturethrough theSMM
codeintheBIOSunderWindows95,Windows3.1x,andMS-DOSoperationsystem
environment.ThisisIntelATXformfactorfeatureandyoushoulduseATXpowersupply.
First,youshouldconnectthepowerswitchcable(providedbytheATXcasesupplier)
totheconnector“PS-ON”(nexttoSW1)onthemainboard.IntheBIOSscreenof
‘POWERMANAGEMENTSETUP’,choose“UserDefined”(or“Min.PowerSaving”or
“Max.PowerSaving”)in‘PowerManager’andchoose“Yes”in‘PMControlbyAPM’.
InWindows95,ifyouwouldliketopoweroff thesystem,youjustchoose“shutdown
thecomputer?”inthe“ShutDownWindows“fromWindows95,thenthesystempower
will beoff directly,andbecomethestand-bystatus.Youwill findthepowerLEDlight
blinking.Ifyouwouldliketorestartthesystem,justpress thepowerswitchbutton,andthe
systemwill bepoweredon.
InWindows3.1xorMS-DOS,youshouldcopytheprogramof“down.com”(youcan
finditinthedisketteoftheIDEdriver) intotheharddrive.Whenyouwouldliketopower
off thesystem,justrun this“down.com”,thenthesystemwill beshutdownandstayin
