Is there any ways using which we can enable AMT in a remotely managed system, without using any host agent or service, since I have a requriement to enable AMT in a bare-metal scenario (i.e. without any OS installed).
You can useBare Metal Configuration, described below:
Bare Metal configuration: The process for bare-metal configuration is the same as for delayed configuration, except that a third-party software agent is not needed, and the configuration server can configure Intel AMT without the one time password. Once Intel AMT is configured, an operating system can be loaded from the network onto the PC, allowing for a completely no-touch configuration of the system with an IT-specified operating system.
