The Intel(R) 11 Series Chipset Family Management Engine Interface A1BB Windows driver is part of the software package required for the Intel Management Engine Interface (MEI). It enables communication between your computer's operating system and the Intel chipset, specifically the Intel 11 Series Chipset Family, which is often used in systems with Intel Core processors. The Intel Management Engine is a small, low-power processor embedded in Intel chipsets, responsible for various low-level tasks, such as system security, power management, and remote management, even when the computer is powered off or in sleep mode.
