Finally got the time to install the beta 1, i strongly recommend having a look at the Supported Configurations document and the release notes (available at Connect) before starting the installation.
For peparation of the site server it is still the guide on Technet that is refereed to in the online documentation “How to Configure Windows Server 2008 for Site Systems” , and it works
Note that In Beta 1, “only English site server is supported for your ConfigMgr v.Next hierarchy and we only support migration from an English ConfigMgr 2007 site.”
A really cool feature is that Nokia Symbian is supported already in Beta 1 of the product, how cool is that!
Check out the Supported Configurations at the following location:
