The ATI graphics and multimedia drivers are installed in computers with built-in ATI graphics hardware acceleration (such as the Power Macintosh G3, the Power Macintosh 5500 and 6500, and the 20th Anniversary Macintosh). They are designed to enable acceleration to the video available at the computer's built-in video port on the logic board, not to the video available via a separate video card, which would offer its own computer video port and require its own software drivers. Also provides 2D graphics acceleration. If this extension starts up with a 'x' over the icon, feel free to delete this extension.
