Intel G43 Graphics Subsystem

The Intel G43 Express chipset contains two separate, mutually exclusive graphics
options. Either the Intel GMA X4500 graphics controller (contained within the 82G43
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 X4500 graphics controller is disabled.
