Product Description

1.5 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 82801G I/O Controller Hub (ICH7) 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 ICH7 is a centralized controller for the board’s I/O paths.

1.5.1

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.
