Product Description DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions. NOTE The use of DVMT requires operating system driver support. 1.5.1.3 Configuration Modes A list of supported modes for the Intel GMA X3000 graphics controller is available as a downloadable document. For information about Supported video modes for the board Refer to Section 1.2, page 15 1.5.1.4 Advanced Digital Display (ADD2/MEC) Card Support The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a 200 MHz pixel clock to the PCI Express x16 connector. The SDVO ports can be paired for a dual channel configuration to support up to a 400 MHz pixel clock. When an ADD2/MEC card is detected, the Intel GMA X3000 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 with the primary VGA 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: • TV-Out (composite video) • Transition Minimized Differential Signaling (TMDS) for DVI 1.0 • Low Voltage Differential Signaling (LVDS) • Single device operating in dual channel mode • VGA output • HDTV output • HDMI/UDI support (when used with the HD Audio Link) 1.5.2 USB The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCIand EHCI-compatible drivers.

DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications.
An example of this
would be when using VGA graphics under DOS.
Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.

NOTE
The use of DVMT requires operating system driver support.
1.5.1.3
Configuration Modes
A list of supported modes for the Intel GMA X3000 graphics controller is available as a
downloadable document.
For information about
Refer to
Supported video modes for the board
Section 1.2, page 15
1.5.1.4
Advanced Digital Display (ADD2/MEC) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
200 MHz pixel clock to the PCI Express x16 connector.
The SDVO ports can be paired
for a dual channel configuration to support up to a 400 MHz pixel clock.
When an
ADD2/MEC card is detected, the Intel GMA X3000 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 with the primary VGA 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:
•
TV-Out (composite video)
•
Transition Minimized Differential Signaling (TMDS) for DVI 1.0
•
Low Voltage Differential Signaling (LVDS)
•
Single device operating in dual channel mode
•
VGA output
•
HDTV output
•
HDMI/UDI support (when used with the HD Audio Link)
1.5.2
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 separate front panel USB headers
