# Intel® PCH Ignition Firmware
Copyright © 2021, Intel Corporation. All rights reserved.

## Overview
Intel® PCH Ignition Firmware is a variant of Intel® Management Engine (ME) Firmware that is intended to provide lightweight chipset initialization. It does not contain all the features of the Intel® Server Platform Services (SPS) ME Firmware. Intel® PCH Ignition Firmware is consequently much smaller than Intel® SPS Firmware (~0.5 MB vs. ~3 MB). Both Intel® SPS Firmware and Intel® PCH Ignition Firmware are specifically designed for server platforms with Intel® Xeon® Processors and are different than the Intel® Management Engine Firmware found on client platforms. This Intel® PCH Ignition Firmware may only be used with 3rd generation Intel® Xeon® Processors.

Note that Intel® PCH Ignition Firmware is mutually exclusive with Intel® SPS Firmware. After flashing and booting Intel® PCH Ignition Firmware, the PCH will be locked to Intel® PCH Ignition Firmware and will not be able to run Intel® SPS Firmware, even if the SPI is re-flashed. Conversely, a system that has Intel® SPS Firmware and has gone through End of Manufacturing (EOM) will not be able to run Intel® PCH Ignition Firmware.
