1.6.1.4 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 X3500 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 S/PDIF connector)
1.6.2

USB

The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-
and EHCI-compatible drivers.
The ICH8 provides the USB controller for all ports. The port arrangement is as
follows:
• Six ports are implemented with stacked back panel connectors
• Four ports are routed to two front panel USB headers

Serial ATA Interfaces

The board provides four Serial ATA (SATA) connectors, which support one device per
connector.
1.6.3.1

Serial ATA Support

The DG35EC Desktop Board's Serial ATA controller offers four 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 four 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
operating system.
