Reap3R , you seem to be very knowledgeable about this. You probably have forgotten more on this issue than I'll ever learn. I was just looking to see if it would be right for me. This laptop (a Dell C640) that dual boots Win 2K Pro & XP Pro SP3 is 7 years old. I upped the RAM from 256MB to 1GB, the max for this model. It runs hot enough as it is now. And I'm not going to spend any more money to keep it going, because I have another one (a Dell D610), the same dual boot setup, and runs twice as fast (2GB RAM). I will keep both of these laptops as long as they run, because the OS's on them are reliable and are still being updated every month. Yesterday, even Win 2K Pro got eight updates. They are old, but when I go to the sunroom or outdoors, I still have a computer. Win 2K starts up slow, but I sometimes use it. XP Pro still has plenty of life in it. But the two of them together doesn't stack up to Win 7. It is simple to use and so far, no problems. But I do want to thank you for your advice. I would like to play, but can't afford a new laptop at this time.
