Authur,
Thank you for your reply! Could you explain your question? I have used both DISM GUI and WDS/MDT to insert many driver/driverpackages during this process. Regarding the install.wim, I haven't attempted adding drivers to it, unless MDT does that when creating the image. Also, I haven't been able to locate "PE" drivers. I have been using drivers found related to windows 7 and my hardware. Maybe I am looking at this incorrectly. Being that I am faily new to WDS & MDT, I am all for being educated on the matter.
Thanks
