I am seriously considering buying a mac pro .... If at all possible, I would like to be able to dual boot, with Leopard or Tiger. Is it possible to boot a Mac Pro with Tiger, from an internal HD or external FW HD? If there is no way possible to boot a Mac Pro from Tiger, is there an emulator that will allow me to run most (or all?) of my old apps that Ive been running on my iBook G4 1Ghz (running Tiger)? Thanks.
