AGP TNT
User's Guide
This release of the display driver is to be used with boards based on the RIVA
TNT chip. This release includes drivers for Win95/98 in either an AGP configuration.
System Requirements to use the AGP TNT Reference Drivers
Win95 System requirements:
- OSR2 for full AGP functionality (which includes Microsoft's OPENGL32.DLL)
- Microsoft's OPENGL32.DLL
- Microsoft's Dx5 or greater
- 2MB disk space
Win98 System requirements
- Microsoft's Dx5 or greater
- 2MB disk space
The following sections will help you install our latest Win95/98
display drivers which include the OpenGL ICD driver.
I. Win95 Installation Information:
If not previously installed, you will need to install these on your system
first:
1. OSR2 or later for AGP systems (usually pre-installed on AGP systems).
(Optionally, the USB supplement is needed for full AGP functionality.
This should have been included with your system or motherboard. See your system
manufacturer's web site for this file.)
2. Install Dx5 or greater (the final version of Dx6 is recommended). This
is contained in your board vendor's drivers, on the Microsoft web site, or on
a recent DirectX application. It is recommended you install the latest
Service Pack from Microsoft. You can obtain this by browsing for "Support Drivers,
Patches and Service Packs" \ "Windows 95 Updates" from:
http://www.microsoft.com/msdownload/default.htm
The final version of Dx6 can be obtained from:
http://www.microsoft.com/directx/default.asp
3. If you have OSR2 or later installed on your system you should already
have Microsoft's OPENGL32.DLL installed on your system. If you do not already
have a version of OPENGL32.DLL in your Windows\System, or you have another
vendor specific OPENGL32.DLL file installed, you need to install
Microsoft's OPENGL32.DLL. You can obtain this file and other required files from:
ftp://ftp.microsoft.com/Softlib/MSLFILES/opengl95.exe
4. Click Start, then Settings, then Control Panel.
5. Start the "Display" applet program.
6. Select the "Settings" tab
7. Push the "Change Display Type" button (or the "Advanced Properties"
button).
8. Push the "Change" button in the "Adapter Type" area.
9. The "Select Device" dialog box will appear, push the "Have Disk" button.
Specify the path to the TNT driver by pressing "Browse..."
10. After selecting the correct path D:\WIN95\RIVATNT (suppose your CD-ROM drive is D:\)
and press "OK".
11. Click "OK" twice to install the new drivers. Close down the open windows.
12. After successfully installing the reference drivers, you will need to
restart the operating system for the new drivers to take effect.
II. Windows 98 Installation Information
Install the driver using the Display Properties dialog box:
1. Click Start, then Settings, then Control Panel.
2. Start the "Display" applet program.
3. Select the "Settings" tab.
4. Push the "Advanced Properties" button.
5. Select the "Adapter" tab.
6. Push the "Change" button.
7. Push the "Next" button.
8. Select the radio button labeled "Display a list of all the drivers in a
specific location..."
9. Push the "Have Disk" button and specify the location where you CD-ROM drive.
The system should find a .inf file in the location you specify (such D:\WIN95\RIVATNT).
10. Press "OK".
11. Click "OK", then "Next", then "Finish"
12. After successfully installing the reference drivers, you will need to
restart the operating system for the new drivers to take effect.
III. WinNT Installation Information:
If not previously installed, you will need to install this on your system
first:
1. Install Microsoft's Service Pack 3 for Windows NT 4.0 on your system.
You can obtain this by browsing for "Support Drivers, Patches and Service
Packs" \"Windows NT Service Packs" from:
http://www.microsoft.com/msdownload/default.htm
2. Choose NT's Start\Settings\Control Panel\Display\Settings\Display
Type\Change\Have Disk\Browse.
3. Locate the folder such as D:\NT40\RIVATNT with the TNT display drivers...
Display should list NVIDIA RIVA TNT
4. After NT successfully installs the display drivers, you will need to
restart the operating system for the new drivers to take effect.
IV. Uninstalling NVIDIA drivers:
If you have a need to do this, first start by uninstalling Control Freak.
1. Click Start, then Settings, then Control Panel.
2. Start the "Add/Remove Programs" applet program.
3. Select Control Freak, and click "Add/Remove".

General information for all users.
About OpenGL:
This OpenGL ICD is now available for both Windows 95 and Windows NT.
It accelerates rendering of OpenGL applications when:
- Display is set to 16-bits per pixel or 32-bits per pixel
- Enough video memory exists to support the OpenGL resolution requested
- Microsoft's OPENGL32.DLL is correctly installed
Several pre-release versions of the OpenGL ICD have previously been made
available through the Internet. This version should be much more stable,
and should perform better in almost all cases.
Microsoft's OpenGL will auto-detect that the RIVA products have hardware-
accelerated OpenGL available, and use that whenever possible. If OpenGL
applications complain about missing required DLL's, or if you are seeing
unusual OpenGL behavior, then it is likely that either you are missing
OPENGL32.DLL, or that an application shipped with a version of
OPENGL32.DLL that is not compatible with the RIVA OpenGL ICD. You should
look in the application's directory for a file called OPENGL32.DLL, and
rename it.
The application will then use the OPENGL32.DLL from the Windows\System or
WinNT\System32 directory. You also can obtain the correct OPENGL32.DLL is
by re-installing it from the WindowsNT CD.
About Control Freak:
Also included in the NVIDIA Reference Drivers is our Control Panel applet,
Control Freak. This applet adds a RIVA tab to the Display Properties Dialog
box. There are several useful controls and setting information here. To learn
what each setting can do, just right click on the setting to get an information
box.
