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-definition front panel audio module to this

connector to avail of the motherboard’s high-definition audio capability.

•

If you want to connect a high-definition 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 specifications.

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 specifications.

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 specifications

When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that

the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI

groups, making the system unstable and the card inoperable.
