Don't even bother. In order for this to work correctly you first need to integrate Update Rollup 2 and then the October 2006 Update Rollup. In order to integrate UR2 you first need to integrate the .NET Framework 2.0. There is no way to actually integrate .NET 2.0 so the UR2 integration only partially installs. Maybe someone can figure out how to fix this and then we can all be happy with integrated SP3 MCE05 discs but until someone can get UR2 and the Oct. 2006 UR into the installation there is no way to do it.
