"x86" is an ambiguous term, because it encompasses also 8086, 80186, 80286; these are CPUs which cannot run a modern operating system. You should instead use i386 i486 i586 i686 i786 for processors with 32-bit instruction set (a.k.a. IA-32), x86_64 for processors with 64-bit instruction set (a.k.a. AMD64 or EM64T) ia64 for processors with VLIW 64-bit instruction set (a.k.a. IA-64). Bruno
