I'm not sure, but doesn't HT require that the chipset (i.e.: northbridge) supports it (would them be only i865 and i875 ???) ??? Which mobo are you running?? And yes, enabling HT in the system's BIOS is required... is that option is not showing up, it must be the case that you mobo doesn't support HT... or does it??? -- Thiago dos Santos Guzella Electrical Enginnering Student - UFMG (www.ufmg.br), Brazil Linux User #354160 UIN: 13465286.
