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.

Chapter 2 

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.
