I have a WILD AND CRAZY IDEA! Why don't you try it for yourself and report back here. This will do two things.
1. Make you think independantly and try things for yourself
2. Make the others here smarter because if anyone wants to know the same thing they will be able to find your post
Seriously, you have the information from AMD the people that make the software and they say XP SP2, you have me someone who was simply guessing that there is not much really difference between SP1 and SP2 and no software I know of will work on SP2, but NOT SP1. So there is a 50-50 chance of it working, if you had already tried you would be done and know the answer, but you chose to wait for someone else to tell you if it will work...
