15.3 Installing a Video Adapter
Physically installing most video cards is very straightforward. Simply choose an available expansion slot (PCI or AGP, as appropriate), seat the video card, and connect the monitor. Nearly all video cards are standalone devices, with the obsolete 3dfx Voodoo 1 and Voodoo 2 as notable exceptions. The Voodoo 1 and 2 are 3D-only video cards. Because they do not provide 2D functions, you must also have a standard video card installed in the system in which you install the Voodoo. The Voodoo serves as a kind of "3D coprocessor," relieving your standard video card of 3D processing duties, but using it for 2D functions.
