I just purchased the new MBP 15" i7 and am going to install XP Pro on Bootcamp so I can run my AutoCAD 2004. I just bought the full version of XP Pro, but not with Service Pack 2. As I read the directions to Bootcamp, its says that it needs to be Service Pack 2. Is this really true? Will I not be able to download the updates necessary to bring it up to SP 2 and then SP 3? Any and all help very much appreciated.
