Hi All: Let me first apologize for the very novice questions. I have an install disk for XP Pro SP2 which seems to work fine if I don't load any drivers (F6). XP validates and I can download updates when NOT using my RAID set (which I need, RAID 1). I don't have a floppy port on my motherboard, so using a floppy is not possible during install. I tried to do a simple slipstream with nLite using the SP2 disk and just the RAID driver, no other options are used. Everything works fine until I try to validate, it fails. So, is there something that I can do, or is the problem direct result of the original XP SP2 media? I am not sure if the product key is OEM. Please help. I have been working on this for a couple of days and need to get this resolved, if possible. Thanks, John
