ACF2 has intercepts that are added during the IPL. Immediately after the IPL, they will all say NO. The first time any intercept is used, the value will change to YES for the life of the IPL. The intercept must be in place so that the GSO option can be changed at anytime without having to do an IPL to turn that on.
