    Apparently Intel is using a different Security Version Number for Trusted Computing Base (TCB, Key Gen) and FPF Anti-Rollback (ARB, Upgrade/Downgrade) at CSME >= 12 firmware. I thought it was the same before. Next version of ME Analyzer will show both.

    I have written a new utility called Dell PFS BIOS Extractor. Basically a python version of PFSExtractor-RS with a few extra features & blink. You can find it at my Various BIOS Utilities for Modding/Research repository, BSD licensed.

    I updated my Intel Microcode Extra Undocumented Header research to add RSAKeySize field and address the new RSA 3072-bit signed microcodes by updating ModuleSize, UpdateRevision, RSAPublicKey, RSAExponent & RSASignature fields. MC Extractor v1.30.0 is out!

    I have written a new utility called VAIO Packaging Manager Extractor. It parses VAIO Packaging Manager executables and extracts their contents, otherwise unlocks them instead. You can find it at my Various BIOS Utilities for Modding/Research repository.

    ME Analyzer v1.80.0 is a big update with initial future platform support, new/improved CSE extensions, robust CSME/CSSPS chipset detection, proper structure revision switching, better CSE File System parsing & output logging, faster/cleaner CSE unpacking.

    I have now updated MEA to v1.72.0 which fixes the -ver86 bug and greatly improves the CSE File System output during unpacking. You should now be able to see around ~31K lines at the same firmware you used. 😉

    Very cool write-up on ME Analyzer and its CSE unpacking. Thank you a lot . Turns out, the output you got is not verbose as there seems to be a bug currently which ignores -ver86 parameter. I will update MEA in the weekend to fix & further improve it.

    Awesome utility to extract a proper BIOS image out of those pesky Toshiba BIOS "COM" files, courtesy of LongSoft.

    I have written a new utility called AMI BIOS Guard Extractor. It parses AMI BIOS Guard (a.k.a. PFAT) images and extracts a proper SPI/BIOS image. You can find it at my Various BIOS Utilities for Modding/Research repository.

    ME Analyzer v1.70.0 adds full parsing & unpacking of all Intel CSE ME/TXE/SPS File Systems (MFS/AFS) based on the amazing initial research by . MEA can now show the FS state and log all low-level details. General CSE firmware analysis also improved.

    Did some more experiments with Rust and Nom, here's a result - a (nearly) complete UEFI IFR parser that converts IFR binary data into human-readable text. Only string and form packages are parsed right now, but that's enough for most IFR files I've seen.

    When themselves recommend to use UEFITool to check the Intel Flash Descriptor access permissions. Cool, nice to see that. Although they should have recommended UEFITool NE for such a task and newer platform, just saying... :P

    I created a repo with various BIOS utilities I've written for modding/research: Dell HDR Module Extractor, Apple EFI Sucatalog Link Grabber, Apple EFI File Renamer, Apple EFI IM4P Splitter and Award BIOS Module Extractor. More info on the readme.
