For best results, install the video device driver supplied with this README file. Follow these instructions for an initial installation of the Trio3D video device driver. See section 4.0 "Updating the Video Device Driver" for replacing the Trio3D device drivers. 1. Start Windows in VGA mode. For instructions on switching to VGA mode, see section 4.0, step 1. 2. Exit from Windows. a. Click on FILE on the Program Manager menu bar. b. Select EXIT WINDOWS from the File pull-down menu. c. Select OK to confirm the request. 3. Switch to the WINDOWS directory (type CD\WINDOWS, and press Enter). 4. Type SETUP, and press Enter. Information about the current Windows configuration appears. 5. Move the highlight bar to the DISPLAY entry and press Enter. "Display" here means a monitor mode or video mode provided by a video device driver. 6. Move the highlight bar to OTHER (at the end of the list) and press Enter. 7. Insert the S3 Trio3D Windows Drivers diskette into drive A and press Enter. 8. Select the desired resolution and press Enter. Refer to the information that comes with your monitor to determine which resolutions your monitor supports. 9. Press Enter to complete the changes. 10. IMPORTANT: If you get a message that the driver is already installed, press Esc to replace the driver. 11. If you are prompted to insert a diskette, type A:\ and press Enter. When the Setup is complete, the DOS prompt appears. 12. At the DOS prompt Type A:\REF-COPY and press ENTER. 13. Remove the diskette; then type WIN, and press Enter to start Windows. The new video device driver is now installed and is controlling your monitor. 14. Repeat this procedure for other resolutions if desired. 3.0 Changing the Video Settings or Refresh Rate ________________________________________________ To change the video settings or refresh rate: 1. Start Windows. 2. In the Main window, double-click on the Control Panel icon. 3. Double-click on the S3 Refresh Rate icon. The screen appearance can be changed using the Desktop area, Color depth, Refresh rate, and Font size settings. 4. When changing only the Refresh rate make your selection then click on the Set button and follow the on screen directions. 5. When changing the Desktop area or Color depth, make your selections then click on the OK button and follow the on screen directions. Note: DDC monitor detection is not supported on Windows 3.1x and Windows for Workgroups. 4.0 Updating the Video Device Driver _____________________________________ To update the video device driver: 1. Select the VGA device driver to control your monitor during the update procedure. This ensures that the video device driver that you are updating is not the same one that is currently controlling your monitor. Use the following procedure: a. Start Windows. b. In the Main window, double-click on WINDOWS SETUP. c. In the Windows Setup window, select OPTIONS from the menu bar. d. Select CHANGE SYSTEM SETTINGS from the Options pull-down menu. e. In the Change System Settings window, click on DISPLAY. f. Click on the down arrow at the Display field. g. In the pull-down menu, click on the VGA driver; then click on OK. h. Click on CURRENT to use the currently installed VGA driver, and click on OK. i. Restart Windows. The VGA driver is now controlling your monitor. 2. Delete the existing S3 video device driver files to prevent the pull-down menu from becoming filled with multiple versions of the same file. a. Open a DOS window. b. Switch to the WINDOWS\SYSTEM subdirectory and find a file named OEMx.INF (where x is a number). If there is more than one of these files, use a text editor to view the files and verify which one is the S3 video device driver file (near the beginning of the file, you will see "S3 Trio3D Windows Drivers Disk"). c. Delete the S3 video device driver file(s). 3. Proceed with the installation instructions in section 2.0 "Installing the S3 Video Device Driver for Windows 3.1x or Windows for Workgroups." 5.0 Trademarks _______________ The following terms are trademarks of the IBM Corporation in the United States or other countries or both: IBM The following terms are trademarks of other companies: S3 and S3 Incorporated Microsoft and Windows are trademarks or registered trademarks of Microsoft Corporation.
