I have find something wrong in this place:http://www.gentoo.org/doc/en/faq.xml#cpus First you need to find our what CPU you use. Suppose it's a Pentium-M. Then you need to find out what CPU it is, instruction-wise, compatible with. You may need to consult the CPU's vendor website for this, although Google is at least as efficient :-). I think in this sentence "First you need to find our what CPU you use.", the "our" must be "out". Reproducible: Always
Thanks for reporting; fixed.
