just a quick question. I realize Old Driver pack used to put DriverSigningPolicy = Ignore NonDriverSigningPolicy = Ignore in winnt.sif And now it no longer there. Is that done on purpose or is it missed? Ed: what is difference NonDriverSigningPolicy and DriverSigningPolicy ? Ed: Did a little more searching.. those 2 were suppose to be added if there were no winnt.sif before. But i see there is a .old Winnt generated so that means there "was" one? And my common sense dictiate that i should have them both in winnt no matter what??
