Intel Active Management Technology (AMT) is hardware-based technology built into PCs with Intel vPro technology.AMT is designed to help sys-admins remotely manage and secure PCs out-of-band when PC power is off, the operating system (OS) is unavailable (hung, crashed, corrupted, missing), software management agents are missing, or hardware (such as a hard disk drive or memory) has failed.
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot firmware, runtime firmware and device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
A part of the Intel AMT web management interface, accessible even when the computer is sleeping. Intel Active Management Technology (AMT) is hardware and firmware for remote out-of-band management of select business computers, [1] [2] running on the Intel Management Engine, a microprocessor subsystem not exposed to the user, intended for monitoring, maintenance, updating, and repairing systems ...
The BIOS versions in earlier PCs (XT-class) were not software configurable; instead, users set the options via DIP switches on the motherboard. Later computers, including most IBM-compatibles with 80286 CPUs, had a battery-backed nonvolatile BIOS memory (CMOS RAM chip) that held BIOS settings. [ 48 ]
The processor must be in protection ring zero ("Ring 0") in order to initiate a microcode update. [21]: 1 Each CPU in a symmetric multiprocessing arrangement needs to be updated individually. [21]: 1 An update is initiated by placing its address in eax register, setting ecx = 0x79, and executing a wrmsr (Write model-specific register).
Fully integrated BMC as a single chip on a server motherboard. The baseboard management controller (BMC) provides the intelligence in the IPMI architecture. It is a specialized microcontroller embedded on the motherboard of a computer – generally a server. The BMC manages the interface between system-management software and platform hardware.
Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
The software is highly dependent on the CPU and specific chips chosen. Most embedded software engineers have at least a passing knowledge of reading schematics, and reading data sheets for components to determine usage of registers and communication system. Conversion between decimal, hexadecimal and binary is useful as well as using bit ...
