Intel used to ask many questions dealing with your appanent "need" for double- precision floating-point calculations, but now they aren't asking as much. If you are going to use your Pentium for any mathematical work now or in the near future, you shouldn't have any trouble getting them to approve you for a replacement. By the way, about your hospital and drug company example: Some of the first people Intel approved for a replacement were INDEED those working in medical labs. Others made the crack about how you should fib that you will be using your Pentium for medical work if you want to be guaranteed a replacement... Check out the comp.sys.intel newsgroup. They've got posters there with torches, pitchforks, nooses, and picket signs saying "Down with Intel!" - Allen "Ninja" Kim
