It said it wasn't aligned right but I couldn't figure out how to get it to do it. Then I used Gparted and it seemed to do it without me telling it anything. The only difference I saw was the little 1Mb partition. Well, I plan to dd the thing and start over with LVM and all so I'll see what it does next time. Maybe I just didn't do something right. Since I have nothing windoze on here, do I really need to worry about DOS booting? All I have is Gentoo here. Dale :-) :-) -- I am only responsible for what I said ...
