But the initial boot screen and os selection screen cannot be displayed without flashing the video card. OSX must be loaded completely to get the user selection screen displayed.
To get the boot screens displayed, the video card must be flashed, http://www.macvidcards.com/ has flashing servive for many cards, ask them.
And you should install the nvidia web driver http://www.nvidia.com/download/driverResults.aspx/105589/en-us for better performance. OSX has a build in driver that captures many cards, but performance is sloooooow.
