Windows 3.1x Driver installation Step 1: Install Windows as you normally would for a VGA display. Run Windows to make sure that it is working correctly. Step 2: In Windows Program Manager, choose Run from the File Menu. At the Command Line prompt, type WINSETUP from your source directory to invoke the install program. Press the ENTER key or click OK to begin the installation. At this point the setup program locates the directory where Windows is installed. For proper operation, the drivers must be installed in the Windows subdirectory. Press to complete the installation.
