It sounds like you are a newbie.
First thing you needs to do was to download a driver from ati.com
then follow instruction in README file to install the driver to enable your 3D acceleration.
Most likely, i wouldn't work, because i been dealing with it for a longtime.
But i would refer to you download a driver at
http://sourceforge.net/project/showf...group_id=84566
with an *.zip extention to enable your 3d acceleration
