This Zip file is ONE OF FOUR 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
