2.5.2 DVMT 5.0 support

DVMT (Dynamic Video Memory Technology driven by OS driver) enables enhanced graphics and memory

performance through highly efficient memory utilization. DVMT ensures the most efficient use of available

system memory for maximum 2-D/3-D graphics performance. More than 512 MB of system memory can be

allocated to DVMT on systems that have 1GB or more of total system memory installed. DVMT returns

system memory back to the operating system when the additional system memory is no longer required by

the graphics subsystem.

DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup) 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.

2.5.3 ADD2 card support

The KTGM45 board 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 (Advanced Digital Display) card is

detected, the Intel GMA 4500 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 card. An

ADD2 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 colour

depths and resolutions.

ADD2 cards can be designed to support one or two of the following configurations:

• LVDS

• DVI output (DVI-D)

• VGA output

• HDTV output

Currently available Kontron ADD2 cards

• P/N 820950, ADD2-LVDS-Dual (LVDS displays must have same display resolution and timing)

• P/N 820951, ADD2-DVI-Dual-Internal

• P/N 820952, ADD2-DVI-Dual

• P/N 820954, ADD2-CRT

2.5.4 PCIe Passive Graphic card support

The KTGM45 board routes two TMDS ports that are each capable of driving up to a 200 MHz pixel clock to

the PCI Express x16 connector. When a TMDS card is detected, the Intel GMA 4500 graphics controller is

enabled and the PCI Express x16 connector is configured for TMDS mode. A TMDS 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 colour depths and resolutions.

PCIe Passive Graphic cards can be designed to support the following configurations:

• TMDS for DVI 1.0

• Display Port

• HDMI support

Currently available Kontron PCIe Passive Graphic cards:

• P/N 820977, KT-PCIe-DVI-HDMI-I, (HDMI, and DVI with TMDS option).

Please visit the Kontron website (www.kontron.com ) for details.
