I have a Z61t 9443-AA1, and I like it. For a new project of mine, I need to install Solaris 11. It only runs on 64-bit machines, though.
My machine has a Core Duo T2400 in it, a 32-bit Core processor. I understand that if I upgrade it to a Core 2 Duo, I would have a 64-bit processor.
I have another machine, a P4, in which the processor has the necessary instruction set (EM64T) to run a 64-bit OS, but the machine won't. Evidently because the motherboard doesn't have the necessary tracings cut into it to actually utilize 64-bit instructions - or at least that's how it was explained to me. My understanding may be false or fallacious.
If I install a T7400 or T7600 in this thing, can I install a 64-bit OS, or will I have to swap the board too?
