1.6 Intel® G33 Express Chipset
The Intel G33 Express chipset consists of the following devices:
• Intel 82G33 Graphics and Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
• Intel 82801IH I/O Controller Hub (ICH9DH) 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 ICH9DH is a centralized controller for
the board’s I/O paths.
The chipset supports the following features:
• Onboard Graphics
• Dynamic Video Memory Technology
• USB
• Serial ATA
• Parallel IDE

1.6.1 Intel G33 Graphics Subsystem

The Intel G33 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel Graphics Media Accelerator 3100 (Intel GMA 3100) graphics
controller (contained within the 82G33 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 Intel GMA
3100 graphics controller is disabled.
