Dear Beng Heng,

I understand that you got VGA passthrough working with Intel DQ45CB and 
an PCI-E x16 ATI Graphics card.

I have Intel DQ45CB and NVIDIA Geforce 8400 GS PCI-E x16.

Could you share with me in details how you got VGA passthrough to work 
with ATI PCI-E x16 when you set onboard VGA as your primary video adapter?

Thank you.
