Chapter 1: Product introduction
Digital audio connector (4-1 pin SPDIF_OUT)
ThisconnectorisforanadditionalSony/PhilipsDigitalInterface(S/PDIF)port.
ConnecttheS/PDIFOutmodulecabletothisconnector,theninstallthemoduleto
aslotopeningatthebackofthesystemchassis.
Front panel audio connector (10-1 pin AAFP)
Thisconnectorisforachassis-mountedfrontpanelaudioI/Omodulethatsupports
eitherHDAudioorlegacyAC`97audiostandard.Connectoneendofthefront
panelaudioI/Omodulecabletothisconnector.
• Werecommendthatyouconnectahigh-denitionfrontpanelaudiomoduletothis
connectortoavailofthemotherboard’shigh-denitionaudiocapability.
• Ifyouwanttoconnectahigh-denitionfrontpanelaudiomoduletothisconnector,
settheAzalia Front PanelitemintheBIOSsetupto[HDAudio].Ifyouwantto
connectanAC’97frontpanelaudiomoduletothisconnector,settheitemto
[AC97].Bydefault,thisconnectorissetto[HDAudio].
PCI Express slot
ThePCIslotsupportscardssuchasaLANcard,SCSIcard,USBcard,andother
cardsthatcomplywithPCIspecications.
PCI Express 2.0 x16 slot
ThismotherboardsupportsPCIExpressx16networkcards,SCSIcards,andother
cardsthatcomplywiththePCIExpressspecications.
PCI Express 2.0 x1 slot
ThismotherboardsupportsPCIExpress2.0x1networkcards,SCSIcards,and
othercardsthatcomplywiththePCIExpressspecications
WhenusingPCIcardsonsharedslots,ensurethatthedriverssupport“ShareIRQ”orthat
thecardsdonotneedIRQassignments.Otherwise,conictswillarisebetweenthetwoPCI
groups,makingthesystemunstableandthecardinoperable.
