Installation (Windows NT)

10.Enter the path of the appropriate PowerStorm display driver and choose OK to download the driver from the CD.

11.In the Change Display dialog box, the display driver whose path you just defined is displayed. Confirm this choice by choosing OK.

The display driver name is shown, for example:

Compaq PowerStorm 300/350 (pbxgdac)

12.When the message displays stating that this is a third party driver, confirm by choosing Yes.

A status box displays reflecting the progress of the driver installation.

13.When the Compaq PowerStorm 300/350 files have been copied to your hard drive, a dialog box indicating that the driver was successfully installed is displayed. Choose OK and remove the CD from the drive.

14.Choose Close to close the Display Type dialog box.

15.Choose Close to close the Display applet.

16.When a message displays stating that you must restart your workstation to use the new display driver, choose No.

17.Shut down your workstation by choosing Shut Down from the Start menu, then remove power from your workstation and install the PowerStorm 300 AGP or 300/350 PCI graphics controller as described in Section 4.2.2 if you haven’t already done so.

18.After installing the PowerStorm 300 AGP or 300/350 PCI graphics controller, reboot your workstation to access the new display driver. After your workstation reboots, a message displays indicating that the default screen resolution and refresh rate are being used. For information on changing these values, see Section 5.2.1.

4.3.6OpenGL Acceleration

OpenGL functionality is available with the OpenGL display driver provided on the Microsoft Windows NT CD. In addition to this generic OpenGL display driver, you have access to an optimized OpenGL display driver from Compaq (pbxgdacogl.dll). This display driver maximizes the performance of applications that are written with OpenGL, and supports OpenGL Version 1.1 and the OpenGL Utility Library (GLU) Version 1.2.

The pbxgdacogl.dll file is located in the %SystemRoot%\system32 directory, where

%SystemRoot%” is the environment variable defining the path of the system root directory; for example, D:\winnt40. For more information on using the Compaq OpenGL display drivers with the PowerStorm 300 AGP and 300/350 PCI graphics controller, see Section 5.3.
