Hi all- i have a memorex DVD/RW. I recently installed x64 on a Sun ultra 20 AMD Opteron server. When I installed the DVD it was recognized by Windows. All firmware and drivers were installed, but the drive does nt recognize any media what so ever. Is it possible that Memorex is not compatible with x64? How can i find out? I have searched the web and cannot find anything relating to my problem or fixing it. While I am at I also have a Nvidia graphics card installed. it works, but on boot my computer takes quite a long time. it flashes the "video cannot be displayed message" for about 1 minute and then finally loads windows. How can i stop this message from being displayed? I disabled the on board VGA adapter, so I am not sure why this is happening.
