Thanks for the response Allan, however, this has nothing to do with embedded. I'm just asking for more information on editing the standard driver's inf file for it to do what I need. There is an entry for display priority in the inf and there's a value assigned. It may be as simple as changing that value but there's no description anywhere on what the other allowed values are.
