Systems Deployment

I am currently using a HII that I created from the Altiris HII tools. It works like most setups and parses through the hardware ids and copies down the appropriate drivers pre-setup, then edits the OEMPNP setup accordingly.

Problem is I edited the sysprep.inf to add a MassStorage id for Vmware and now it seems that when an image comes down all the drivers are there and the OEMPNP folders are enumerated but the New Hardware Device Wizard still comes up. I just have to click Next through it but it appears the drivers arent taking right on the sysprep.

Any ideas?
