>PCI Express Configuration

Active State Power-Management – [Disabled] or [Enabled]

This field enables or disables PCI Express L0 and L1 link power states.

PCI Express Port 1 – [Disabled] or [Enabled]

PCI Express Port 2 – [Disabled] or [Enabled]

PCI Express Port 3 – [Disabled] or [Enabled]

PCI Express Port 4 – [Disabled] or [Enabled]

VC1 for Azalia & Root Ports – [Disabled] or [Enabled]

This field Enables or Disables Virtual Channel 1 for PCI Express Root Ports and the Azalia controller (Intel High Definition Audio) to support true isochronous data transfers.

>I/O Interface Configuration

Onboard Audio Controller – [Azalia], [AC97], or [Disabled]

If this field is set to [AC97], the onboard AC'97 CODEC is selected.

If this field is set to [Azalia], the onboard Intel High Definition Audio controller is selected.

Onboard Ethernet Controller – [Disabled] or [Enabled]

This field must be set to [Enabled] to use the LAN Boot feature (PXE Boot to LAN).

Onboard Floppy Controller – [Disabled] or [Enabled]

If this field is [Enabled], the onboard floppy controller is selected over the Parallel Port and the entry, 1st Floppy Drive, appears in the boot order under Boot Device Priority when Device Type is selected. You must select a Floppy A type, typically [1.44 MB, 3 1/2"] to use this feature. The Parallel Port can not be enabled since these two devices share the same pins to the baseboard connector.

If this field is [Disabled], the Parallel Port can be Enabled by selecting one of the Parallel port address.

Floppy A – [Disabled], [360 kB, 5 1/4 "], [1.2 MB, 5 1/4"], [720 kB, 3 1/2"], [1.44 MB, 3 1/2"], or [2.88 MB, 3.5"]

Serial Port 1 Configuration – [Disabled], [3F8/IRQ4], [3E8/IRQ4], or [2E8/IRQ3]

Serial Port 2 Configuration – [Disabled], [2F8/IRQ3], [3E8/IRQ4], or [2E8/IRQ3] Serial Port 2 Mode – [Normal], [IrDA], or [ASK IR]

∗ If this field is set to [IrDA] or [ASK IR], the Infrared settings below appear on screen.

IR Duplex mode – [Half Duplex] or [Full Duplex]

IR I/O Pin select – [SINB/SOUTB] or [IRRX/IRTX]

Parallel Port Address – [Disabled], [378], [278], or [3BC]

You can only change this feature from [Disabled] to another setting if the Onboard Floppy Controller is set to [Disabled]. If [378], [278], or [3BC] are selected, the following items appear on screen.

Parallel Port Mode – [Normal], [Bi-Directional], [ECP], [EPP], or [ECP&EPP]

If [Normal] is selected, the standard parallel port mode is used. This is the default setting.

If [Bi-Directional] is selected, the data is sent to and received from the parallel port.

If [ECP] is selected, the ECP Mode DMA Channel appears below. The ECP parallel port can be used with devices adhering to the Extended Capabilities Port (ECP) specification.
