Installing Autocad 2000 on a Windows XP machine.

I know that I am a little out of date with my preference of Autocad 2000, but it simply happens to be my version of choice. I was able to install it on a 1 GB machine a couple of years ago, but I am unable to install it on my 1.8 AMD machine now. I get an error message, "Wrong OS, Autocad supports NT 4.0, 5.0, Win 95 and Win 98." Does anyone here know of a way around this? I have shown that it is possible, it would seem that someone of higher computer skills than I may have run across this and knows some sort of end-run. I am using Windows XP Professional. Thanking you all, in advance, G. De Angelis
