I think you type pretty fast if you did that in five minutes.

arround 80-90 WPM

That's about the speed I type, anyways, x86 gentoo is still using lilo? I only use gentoo on my Sun workstation, so it uses silo, but I figured they'd have hopped on the grub bandwagon for x86 by now.

Well its more of a personal prefrence thing mainly, both grub and lilo are recomended so its really up to the user.
