Wrong Kernel? [Solved]

[Rhythm]

I'm trying to install Sabayon 5.3 GNOME on my netbook. This is my first Linux installation of any kind.

I downloaded Sabayon_Linux_5.3_amd64_G.iso from this mirror: http://mirror.umoss.org/sabayonlinux/iso/
and used a universal USB installer to write it to a USB stick. I booted my netbook from it, and I get this message:

"This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU."

I don't get it, isn't this the one I'm supposed to use?
If it makes any difference, the specs of my netbook are:
Intel ATOM CPU N270. 1.6Ghz, 1GB of RAM, 250GB hard drive.
Please help me, I spent 7+ hours downloading and writing it to my USB drive.

No. The Intel Atom N270 is only 32-bit. Only the Intel Atom 230 and 330 support 64-bit operating systems and applications.

Rhythm, you need to download the file Sabayon_Linux_5.3_x86_G.iso (and Sabayon_Linux_5.3_x86_G.iso.md5 so that you can check that the MD5 checksum of the ISO file you downloaded is correct).
