I have Core 2 duo E660, and i dont know which install download. I have tried amd64 but at begining i had problems (maybe not connected) with error at booting and selecting root or shell (it speaks to me everything).
Im newb, at gento and its first system on this computer

I hope you will have any patience for me, and i want to apologize if i made anyone angry. Im just some kind of virgin-queen in opression.
SOLVED
What happens is that no PATA drives are found, including your cd-rom. You can force the system to detect your cd-rom by typing this at the prompt:
gentoo all-generic-ide
Thanks ewerybody :]
