Product Description

1.6Intel® 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

1.6.1Intel 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.
