Set PRTC Select Set PRTC in Intel AMT configuration menu. In Set PRTC menu, enter PRTC in GMT (UTC) format (YYYY:MM:DD:HH:MM:SS).

Idle Timeout Select Idle Timeout in the Intel AMT configuration menu, you will be prompted to input a timeout value in "Idle Timeout" menu. The value should be entered in minutes. This setting is used to enable or disable Intel ME Wake on LAN feature and define Intel ME idle timeout when ME WoL power policy is selected. Driver description Read the following drivers description, if you are going to use the Intel AMT technology in Windows environment. MEI The Intel AMT Management Engine Interface (MEI) is the interface between the host and the Intel Management Engine (ME). The Intel AMT MEI is bi-directional, and either the host or the Intel AMT firmware can initiate transactions. In addition, transactions can be completed asynchronously by the Intel AMT ME and then synchronized later. LMS Local Manageability Service (LMS) is a service that runs locally (in the user space) in the host operating system. LMS exposes AMT functionality through standard interfaces (for example: general-info interface, firmware update interface, local agent-presence interface, and so on.) LMS is an abstraction that sits on top of the HECI driver (and the ME) that interacts with the ME using standard interfaces. LMS listens for the request directed to the AMT local host. When an application sends SOAP/HTTP message addressed to the local host, then LMS intercepts the request and routes the request to the Management Engine Interface through the HECI driver. SOL Serial Over LAN (SOL) driver is an Intel AMT ME driver. This driver enables the remote display of managed client user interface through management console and emulates serial communication over a standard network connection. 18 ThinkCentre M58p with Intel AMT White Paper
