Troubleshooting - Diamond Multimedia Viper V770 User Manual

5
If you experience a problem using a Viper V770 board under Windows 98,
there are three possible causes of your problem:
Your application is incompatible with the Viper V770 or is not compatible
with Direct3D or OpenGL.
The Viper card not properly installed (seated incorrectly).
Viper drivers are not correctly installed.
Try the following:
Check your game manufacturer's specifications to verify its compatibility
with Direct3D, OpenGL and Viper V770.
Shut down your computer and double-check the cable connections. Make
sure that the Viper card is properly seated in its AGP slot.
Re-install the Viper drivers using the Viper Installation CD.
Viper V770 Requires An IRQ
The nVIDIA TNT2 chip requires an IRQ to function correctly. If no IRQ has
been assigned to the card by the motherboard BIOS you may experience
symptoms such as Windows not booting, or extremely poor performance.
The symptoms mostly involve error messages such as While initializing
device, VDD. Windows Protection Error. You must restart your
computer, and, While initializing device, NVRM. Windows Protection
Error. You must restart your computer. Some motherboard BIOS's
allow for an option to "Assign IRQ for VGA." Often, the latest BIOS will also
resolve this problem. Check with your motherboard manufacturer for
information on updating your BIOS.
