Intel® (CS)ME, CS(TXE), CS(SPS), PMC, PHY & PCHC:
Firmware Repositories


Last Updated: 2020-10-04
This is a collection of every Intel® Engine (CSME, CSTXE, CSSPS, ME, TXE, SPS), PMC, PHY & PCHC firmware we have found. You can use ME Analyzer to check instantly whether a firmware is already at the repository.

Note: To extract the files below you need to use programs which support RAR5 compression!

A. About Intel® Engine, PMC, PHY & PCHC Firmware Repositories


Collecting all available Intel® Engine, PMC, PHY & PCHC firmware is important for research on how the general technology works, for creating universal tools that can help people understand what firmware they use, for developers with no Intel® representative who want to experiment on a given platform, for downgrading purposes etc.

All Intel® Engine, PMC, PHY & PCHC firmware at the repository have some common attributes and are categorized based on them as follows:

  • Every Engine firmware version tag has a Major, Minor, Hotfix & Build number. Example: ME 8.1.40.1416 has Major 8, Minor 1, Hotfix 40 and Build 1416.
  • Every PMC CNP+, PHY & PCHC firmware version tag has only a Build number. Example: PMC 300.2.11.1011 has Build 1011.
  • The SKU of each firmware, when applicable, depends on the platform generation and is usually distinguished based on supported features (Consumer H/LP/N/V/1.5MB, Corporate H/LP/5MB etc).
  • The Revision is the PCH stepping of a given platform generation and is used to further categorize CSE & PMC firmware (C, D, B etc).
  • The Release of each firmware can be Production (PRD), Pre-Production (PRE) or ROM -Bypass (BYP). You could see these as Stable, Debug & Alpha but there's a lot more to it than that. Only Production (PRD) Engine, PMC, PHY & PCHC firmware based on Production PCH Steppings are included in these repositories.
  • The Type of each firmware can be Stock (RGN), Extracted (EXTR), Recovery (REC), Operational (OPR) or Update (UPD). RGN are clean/stock/unconfigured images provided by Intel® to OEMs. EXTR(-Y/N) are dirty/extracted/configured images from various SPI/BIOS . REC & OPR are used at (CS)SPS firmware. UPD are partial RGN/EXTR firmware regions which contain only ME CODE without any DATA, used only by older Intel® FWUpdate tool versions. To learn more, read Section B of Intel Management Engine: Drivers, Firmware & System Tools.

There is a certain mentality which is followed in order to structure the Intel® Engine, PMC, PHY & PCHC firmware repository properly:

  • Every Engine firmware filename follows the structure Major.Minor.Hotfix.Build_SKU_Revision_Release_Type and has a .bin extension. CSME 11 PCH-LP additionally has a PDM entry. Example: 11.0.0.1180_CON_LP_C_NPDM_PRD_RGN.
  • Every PMC CNP+ firmware filename follows the structure PCH-Name_PCH-Series.PCH-SKU.PCH-Revision.Build_SKU_Revision_Release and has a .bin extension. Example: CNP_300.2.11.1011_H_B_PRD.
  • Every PMC APL/BXT/GLK firmware filename follows the structure PCH-Name_Major.Minor.Hotfix.Build_SKU_Date_Release and has a .bin extension. Example: APL_0.1.0.0_B_2020-02-05_PRD.
  • Every PHY firmware filename follows the structure PCH-Name_PHY-SKU_Major.Minor.Hotfix.Build_Release and has a .bin extension. Example: LKF_S_10.227.203.1144_PRD.
  • Every PCHC firmware filename follows the structure PCH-Name_Major.Minor.Hotfix.Build_Release and has a .bin extension. Example: ICP_13.0.0.1004_PRD.
  • When it comes to Engine Region images (RGN/EXTR), RGN are more important that EXTR(-Y/N) and EXTR-Y are more important than EXTR-N. ME Analyzer can detect that as well.
