Smart Start 8.0 X32 with Windows 2008 Server

[Dürig]

Hello..I want to use as usual before setting up a new Server (in our CAse it's a DL380 G4), with the Smart Start CD. With Windows 2003 no problem, but when i want to install Windows 2008, after choosing the correct Server Edition (in my Case its a Windows 2008 Enterprise German), and then after copying all files, it ask's for the Windows CD, this is also normal and done xx before, and then i enter the Windows CD, klick continue, and then there is a line and smart start ask's for "Flat Files" so i can brows arround but have no idear what to choose so i can run Windows..Does anybody have a idear? Thanks Roy
