I did as you said when I first started loading XP. I loaded the drivers for promise after hitting F6, the whole installation went fine untill my first reboot, But after moving the drive back to IDE #1 ,loading the OS,installing the promise drivers, and then moving the the drive back to IDE #3 Raid every thing is fine. The only problem I have now and had it every time is installing the network printer from my other PC. XP sure has a stange and tedious way of setting up the network. Some time it will work flawless and the next time it is like pulling teeth. The other night I had a friend that installed Norton Anti virus 2002 and after the install he lost his printer and sound(this was on win98) I took a look and the sound card took the same address as LP1.I got everything back in order, but that shows you how strange thease PC's can act. Thanks for the help and take care. Bruce
