hello there,

yes you have to have a working osx for running the installer script, partition it with GUID and then you need to restore the original DVD or image that i suppose you have of SNow Leopard 10.6 onto it. After your USB is ready you proceed to boot with -v or cpus=1 if you need it,

cheers
