There is an NVIDIA Solaris Driver web forum. You can access it by going to http://www.nvnews.net and following the "Forum" and "Solaris Discussion Area" links. This is the preferable tool for seeking help; users can post questions, answer other users' questions, and search the archives of previous postings.

If all else fails, you can contact Sun Microsystems for support at http://sunsolve.sun.com, or your local service provider.
