Now this is the big quetion, which frankly is yet to be answered.

Does my processor work in 32-bit or 64-bit mode? I looked under System, in DXDIAG and even in the BIOS prefs but the only message I keep getting is "Genuine Intel(R) CPU T2250 @ 1.73GHz (2 CPUs)". The thing is that the laptop is fairly new and I wouldn't mind running a 64-bit Vista on it, however, that'd only make sense if I have a 64-bit CPU. Can anybody help?
