Teo,
I checked their datasheet now, and found a description that
Directed I/O registers are 82Q45 only(oh, my god)
http://www.intel.com/Assets/PDF/datasheet/319970.pdf
p.425
Actually VT-d settings are shown in BIOS setup,
but VT-d may not be implemented in Q43 chipset... ;)
thanks,
Takeshi HASEGAWA
