Cloning to computers with ATA100 drivers

We use symantec Ghost on our network. I have had many troubles ghosting images that have been created from a machine prior to the new Intel ATA 100 drivers. I can successfully ghost ATA100 machines one to another (sysprep 1.1). I have read the Symantec and Microsoft instructions on how to change the Sysprep.ini file to point to the new drivers and I still can’t get it to work…what’s the trick?
