      1.0  Installing the S3 Video Device Driver for Windows NT 4.0
      2.0  Configuring Your Monitor
      3.0  Changing the Video Settings
      4.0  Setting Your Monitor to VGA Mode
      5.0  Trademarks

IMPORTANT NOTE:  Because the Trio3D operates as an AGP device, Service
                 Pack 3 for Windows NT 4.0 must be installed on your
                 system for the device drivers to work properly using AGP.
                 If you do not install the service pack, the drivers will
                 not work correctly and Windows NT will default to VGA
                 operation only. Service Pack 3 is available for free download
                 from Microsoft's web site at http://www.microsoft.com/.
