When I installed Windows 7 Beta on my P6T equipped machine, there were no drivers specifically for it. The drivers for Vista only worked partially. Now that Windows 7 RC is out, Asus has finally released the drivers. For those who are interested about the drivers for Windows 7. Please visit this page.
Select Motherboard, LGA 1366 and P6T to search for drivers.
You will see a prompt to select OS. Select Windows 7 or Windows 7 64bit to get to the download page.
