See "Intel vPro Technology" under "Advanced Technologies" here: AMT is just a SUBSYSTEM of ME and not all chipsets are CAPABLE of it. It can be used to communicate with the AMT SUBSYSTEM to access AMT CAPABILITIES in the firmware. The ME Interface (notice the Interface word) is a software interface that is used to communicate with the ME firmware. The Intel Management Engine Interface is bi-directional, as either the host OS or the Management Engine (ME) can initiate transactions.Įven this text you are quoting is explaining things you are not seeing. In other words, communication between the local host operating system (OS) and the Management Engine (ME) is accomplished by means of the Intel Management Engine Interface driver.
The Intel Management Engine Interface (Also known as HECI) driver is a software interface that is used to communicate with the Intel® AMT subsystem(Management Engine) in the Management Engine (ME) to access Intel® AMT capabilities in the firmware. LMS is actually a proxy service, which transfers TCP requests (open connection, close connection & TCP packets), between host management applications and the Management Engine in the firmware, via the Intel Management Engine Interface host driver.īoth LMS and MEI driver are essential for any local AMT applications and agents that need to access AMT on the local system. In short, LMS enables local management applications to send requests, and receive responses to the local Intel® AMT device. LMS listens for requests directed to the Intel® AMT local host and intercepts SOAP/HTTP messages addressed to the local host and routes them to to the Management Engine via the Intel Management Engine Interface driver. The Local Manageability Service (LMS) is a service that runs locally (in the user space) on the host operating system. The Intel Management Engine Interface is bi-directional, as either the host OS or the Management Engine (ME) can initiate transactions. The Intel Management Engine Interface (Also known as HECI) driver is a software interface that is used to communicate with the Intel® AMT subsystem (Management Engine) in the Management Engine (ME) to access Intel® AMT capabilities in the firmware. The main two components of the openamt project are the MEI driver and LMS.
The OpenAMT project is the place where you can find Intel® AMT open source drivers and tools supporting local OS access to Intel hardware manageability features.
