Product Description

1.6.1.5 Advanced Digital Display (ADD2/MEC) Card Support

The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a

225 MHz pixel clock to the PCI Express x16 connector. When an ADD2/MEC card is

detected, the Intel GMA 3100 graphics controller is enabled and the PCI Express x16

connector is configured for SDVO mode. SDVO mode enables the SDVO ports to be

accessed by the ADD2/MEC card. An ADD2/MEC card can either be configured to

support simultaneous display or can be configured to support dual independent display

as an extended desktop configuration with different color depths and resolutions.

ADD2/MEC cards can be designed to support the following configurations:

• Low Voltage Differential Signaling (LVDS)

• Single device operating in dual channel mode

• HDTV output

• HDMI support (when used with the HD Audio Link)

1.6.2 USB

The board supports up to 12 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-

and EHCI-compatible drivers.

The ICH9DO provides the USB controller for all ports. The port arrangement is as

follows:

• Six ports are implemented with stacked back panel connectors

• Six ports are routed to three separate front panel USB headers

For information about Refer to

The location of the USB connectors on the back panel Figure 10, page 44

1.6.3 Serial ATA Interfaces

The board provides five Serial ATA (SATA) connectors, which support one device per

connector. The board also provides one red-colored external Serial ATA (eSATA)

connector.

1.6.3.1 Serial ATA Support

The ICH9DO I/O controller offers six independent Serial ATA ports with a theoretical

maximum transfer rate of 3 Gbits/sec per port. One device can be installed on each

port for a maximum of six Serial ATA devices. A point-to-point interface is used for

host to device connections, unlike Parallel ATA IDE which supports a master/slave

configuration and two devices per channel.

For compatibility, the underlying Serial ATA functionality is transparent to the

operating system. The Serial ATA controller can operate in both legacy and native

modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14

and 15). In Native mode, standard PCI Conventional bus resource steering is used.

Native mode is the preferred mode for configurations using the Windows* XP and

Windows Vista* operating systems.
