In addition to that you can fine tune FreeBSD to match your exact CPU but that requires kernel and modules and ports rebuild: https://wiki.freebsd.org/UsingCPUTYPE As simple as that :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info --0000000000009e6d4c062b1bd0d8 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"auto"><div>AMD64 is equal to x86_64 and means 64-bit CPU PC (AM= D or Intel).</div><div dir=3D"auto"><br></div><div dir=3D"auto">x86 is for = 32-bit CPU.</div><div dir=3D"auto"><br></div><div dir=3D"auto">64-bit PC ca= n run 32-bit OS, but not the other way 32-bit PC cannot run 64-bit OS.</div= ><div dir=3D"auto"><br></div><div dir=3D"auto">In addition to that you can = fine tune FreeBSD to match your exact CPU but that requires kernel and modu= les and ports rebuild:</div><div dir=3D"auto"><br></div><div dir=3D"auto"><= a href=3D"https://wiki.freebsd.org/UsingCPUTYPE">https://wiki.freebsd.org/U= singCPUTYPE</a></div><div dir=3D"auto"><br></div><div dir=3D"auto">As simpl= e as that :-)</div><div><br></div><div data-smartmail=3D"gmail_signature">-= -<br>CeDeROM, SQ7MHZ, <a href=3D"http://www.tomek.cedro.info">http://www.to= mek.cedro.info</a></div></div> --0000000000009e6d4c062b1bd0d8--
