This Zip file is ONE OF FOUR [install setup NT NT4] from the Stealth 3D 2000 install CD. You use the Setup.zip and the Install.zip files to install the files in the zipped OS files. [Note NT is NT 3.51, I think!] I have successfully used this CD to install Stealth 3D 4000 video adapter on NT 4.0. Follow the instructions for MANUAL INSTALLATION.
NOTE!!!--- instructions say that your display MUST be set to 640x480 when you start the installation of these drivers!!!
Hope this is what you are looking for!! GL
