My Radeon 9100 worked ok but had some artifacts with the icons used to rotate an object. So I followed their instructions and downloaded the latest graphics drivers from ATI. Now I get a notice that it is unsuported and it locks up win 2000 pro so only a power down and a re boot can free up the PC. That was with OpenGL now I have to use it without OPen GL so I am worse off unless I go back to the original drivers.,,,,,,,this is sad.
