Power LED
TheProcessorBoardprovidessupportforanexternalpowerLED
throughtheonboardMotion/PowerLEDconnector.ThisLEDis
controlledthroughtheSMC37C935GPIOpins.OncetheSMCchipis
programmedtosupportthePowerLEDfunctiononGPIOpin13,the
LEDisturned“on”anytimeallpower
totheProcessorBoardisgood.
Thesystem’spowermanagementsoftwarehastheoptiontoturnthe
LEDoffindicatingthesystemisinapower‐managedmode.
MSR
TheMSRinterfacesupportsamaximumof3tracksofmagneticstripe
informationforsupportofISOorJISformatcards.Activate
theMSR
interfacebyenablingitinBIOSSetupunderIOConfiguration.The
MSRinterfacecontrollerisamemory‐mappeddevice,whichcanreside
atsystemmemoryaddressesCA000,CC000,orD0000.IfMSR
capabilityisnotdesired,itmaybedisabledthroughBIOSSetup.
Board BIOS
TheProcessorBoardusesaPhoenixBIOS,whichisstoredinFlash
ROMandeasilyupgradedthroughthenetworkconnectionorserial
port.TheFlashEEPROMalsocontainstheSetuputility,Power‐OnSelf
Tests(POST),andAPM1.2.TheboardalsosupportssystemBIOS
shadowing,whichenablestheBIOSto
executefromonboardwrite‐
protectedDRAM.
TheBIOSdisplaysasign‐onmessageduringPOSTidentifyingthetype
ofBIOSandafive‐digitrevisioncode.
