Follow the 2K keys and that should get you working...

There was an app...can't remember what it was but I saw it on Betanews...that logged all the keys hit during an install. Log the installer and you will be good to go.

And not to shoot your project down or anything...but is there a reason you aren't just doing the install and then building a drive image?
