22 Hmmm, then I guess I didn't do something right the first time I tried
23 cgdisk then. It said it wasn't aligned right but I couldn't figure out
24 how to get it to do it. Then I used Gparted and it seemed to do it
25 without me telling it anything. The only difference I saw was the
26 little 1Mb partition.

28 Well, I plan to dd the thing and start over with LVM and all so I'll see
29 what it does next time. Maybe I just didn't do something right. Since
30 I have nothing windoze on here, do I really need to worry about DOS
31 booting? All I have is Gentoo here.
