i gave this code: $ if cat /proc/cpuinfo | grep " lm " &> /dev/null; then echo "Got 64bit" ; fi and i get this reply back: "Got 64bit" so i my pc is capable of 64 bit. now is it ok if i download this torrent?: ubuntu-10.04-desktop-amd64.iso.torrent my doubt is, my pc is intel while the link talks about amd.... any suggestion would be greatly appreciable. thanks a lot.
