Hi, what is the best method to add a new driver to an existing driver package? For example. Say I create a driver package for a device and then I need to add a new driver to it at a later date. 1. What I really don't want to do is create a new driver package and distribute it again. 2. What I would like to be able to do is add the new driver to my driver sources folder, associate the new driver to the driver package and distribute the delta changes to the driver package on the distribution point. Is this possible and if so do you know of any good tutorials on how to do it. It looks feasible but I need a primer. Thanks
