Intel Q45 Graphics Subsystem

The Intel Q45 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel Graphics Media Accelerator 4500 (Intel GMA 4500) graphics
controller (contained within the 82Q45 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
4500 graphics controller is disabled.
