Intel ® 945G Chipset; Intel 945G Graphics Subsystem - Intel BOXD945GBOLKR Technical Product Specification

1.6 Intel ® 945G Chipset
The Intel 945G chipset consists of the following devices:
•
Intel 82945G Graphics Memory Controller Hub (GMCH) with Direct Media Interface (DMI)
interconnect
•
Intel 82801GH I/O Controller Hub (ICH7DH) with DMI interconnect
The GMCH component provides interfaces to the CPU, memory, PCI Express, and the DMI
interconnect. The component also provides integrated graphics capabilities supporting 3D, 2D and
display capabilities. The ICH7DH is a centralized controller for the board's I/O paths.

1.6.1 Intel 945G Graphics Subsystem

The Intel 945G chipset contains two separate, mutually exclusive graphics options. Either the
GMA950 graphics controller (contained within the 82945G GMCH) is used, or a PCI Express x16
add-in card can be used. When a PCI Express x16 add-in card is installed, the GMA950 graphics
controller is disabled.
