You can use SCS for provisioning your system in the Enterprise mode if you are fine with IIS, .Net and SQL components. And you need to do it only once - you don't have to do it each time you power on the system unless you reset the CMOS settings.
You can download the latest version of SCS here
There are 3 modes or stages that the AMT system has to go through before it is operationa- factory mode, setup mode and operational mode. AMT system comes from factory in factory mode whereAMT is unconfigured. When the user configures the AMT settings through Bios, it enters into setup mode. This is the stage where it waits for configuration settings from SCS. Please read more about this processes in the Developers' guide for SCS
