NT4, Half-life, ATI RagePro 4 MB <== Is OpenGL even POSSIBLE?

The system is a Dell Optiplex GXa running NT4 with an on-board ATI Rage Pro 3D 4MB. I downloaded all possible version for it; from Dell and ATI itself. They all claim to support openGL, but every one has FAILED.

Half-life always report “Your card does not support the selected mode” (tried them all) when using atir3icd.dll. Only MS opengl32.dll with 0.2 fps seems to work… Can’t install DirectX on NT either.

Has anyone ever been able to get the above combination working? Please help… I’m ready to start suing companies!
