I would appreciate any help from people that have done this sort of project before...

First i will slipstream my os's with the newest servicepacks/updates. Then Change the PIDs (easier then taking source from each cd).
Next I will Slipstream the driver packs. Setup the Unnattended scripts with the basic info (OWNER for name and * for computer name etc) and will skip the key until first boot if possible.

After this i have to figure out how to script the oemscan.exe found in the forums to auto find and replace oembios files before copy to install os.

Then Setup my multiboot by utilizing the guide found at the following url: http://flyakite.msfn.org/

And after all is good with that then id like to use wpi to help make software install customizeable...

Any thoughts?...
