Hi AMD, although it's my first post here: you're first steps have been right (referring to your screenshots) - you only missed two things: 1. Add "DriverSigningPolicy=Ignore" to your winnt.sif [unattended] and much more important 2. Add your si3114r.sys to your I386-folder on your xpcd - otherwise your HD won't be recognized. But don't forget to use makecab (you'll find it in your I386-folder). Everything has been posted here - It's raskren's method: http://www.msfn.org/board/index.php?showtopic=13173 Greetings, Gandalf2
