Intel Desktop Board D910GLDW Technical Product Specification 1.6.1.1 Dynamic Video Memory Technology (DVMT) DVMT enables enhanced graphics and memory performance through Direct AGP, and highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 224 MB of system memory can be allocated to DVMT on systems that have 512 MB or more of total system memory installed. Up to 128 MB can be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system memory. Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is 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 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. 1.6.2 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH6 provides the USB controller for all ports. The port arrangement is as follows: • Four ports are implemented with dual stacked back panel connectors adjacent to the audio connectors • Four ports are routed to two separate front panel USB connectors NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. For information about Refer to The location of the USB connectors on the back panel Figure 11, page 42 The location of the front panel USB connectors Figure 12, page 44 1.6.3 IDE Support The board provides five IDE interface connectors: • One parallel ATA IDE connector that supports two devices • Four serial ATA IDE connectors that support one device per connector 20

1.6.1.1
Dynamic Video Memory Technology (DVMT)
DVMT enables enhanced graphics and memory performance through Direct AGP, and highly
efficient memory utilization.
DVMT ensures the most efficient use of available system memory for
maximum 2-D/3-D graphics performance.
Up to 224 MB of system memory can be allocated to
DVMT on systems that have 512 MB or more of total system memory installed.
Up to 128 MB can
be allocated to DVMT on systems that have 256 MB but less than 512 MB of total installed system
memory.
Up to 64 MB can be allocated to DVMT when less than 256 MB of system memory is
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 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.
1.6.2
USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and
EHCI-compatible drivers.
The ICH6 provides the USB controller for all ports.
The port arrangement is as follows:
•
Four ports are implemented with dual stacked back panel connectors adjacent to the audio
connectors
•
Four ports are routed to two separate front panel USB connectors
±
NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device is attached to the cable.
Use shielded cable that meets the
requirements for full-speed devices.

IDE Support
The board provides five IDE interface connectors:
•
One parallel ATA IDE connector that supports two devices
•
Four serial ATA IDE connectors that support one device per connector
