If you install this keyboard quite normal for Windows works most immediately. Here then are missing but the multimedia functions and key combinations for functions such as "print", "Down", "Page Up" and most importantly "Del".
In order to achieve the one to get the Windows driver of "Boot Camp" from a MacOS X DVD. After that everything works. However bothers me here is that the F-keys (F1, F2, ... F12) can only be reached via shortcuts: If you press F11, for example, the volume is reduced. Only with Fn + F11 you have the function of the F11 key. This behavior is useless in many Windows programs. Especially in games.
Instead of the Boot Camp driver I use uawks. Here everything works the way I imagine it. However, the current version 2008.09.17 shows a German keyboard the strange behavior that after pressing the right Alt key, which is interpreted as AltGr, each keystroke is modified with Ctrl. So it is then so that each keystroke behaves as holding down the Ctrl key. To fix the problem, there are on the side of uawks already an entry in the bug tracker with solution. The entry date 27.12.2010 also includes a finished version to download.
