2 ?'s
1. How can what you want to do not be done with a unattended setup. what cant you do now in a unattended setup that makes you look for another way to do it.
2. How does ghosting not solve this problem. I would imagine dell creates 1 image using sysprep then use's that image as a master to ghost to the actual thousands of pc's they intend on selling. What do you want now that cant be don with ghost??
Im confused, because if you just want to install on 1 machine, then a unattended setup would work. If you want to install on several machines with the same spec's then ghosting a image would work.
I hope your not trying to create a "automatic" installation for computers of different types. That will never work because of different hardware in each machine.
Best way to do this imo, is to install the system WITHOUT PlugNplay active, then ghost that image over. Next time you ghost that image to a new machine on first boot PlugNPlay will start and ask for the required drivers then. If you install a os WITH pnp enabled, then it set's up the hardware during installation. So it would then install your gcard, scard, and all others during setup. So you could ghost that image because if you tried that same image on another machine odds are that other machine does NOT have the same gcard, scard, etc...
What your trying to do i think does not exist. Read the sysprep doc's. It aswell gives you the same suggestion's of what i typed above (although mines in a nutshell).
Sysprep isnt used for anything but installing a windows OS on multiple comuputers of the same hardware specs.
