I don't have a specific site for you. I can tell you from my experience with the above senario, you will want to manually enter the MassStorageDevices option into the sysprep.inf file if that is the way you are deploying your systems.
Not adding that option will most likely result in a blue screen when you try to start up an imaged system. It will also allow you to deploy your image to a wider range of systems beyond the current model of Dell your are currently deploying.
Hope that information is helpful. Feek free to contact me if you need further information.
