Old BIOS request(s) T550 and/or T440

[microwave_highvoltage]

Hi there!

The following request might well shatter the rules, however I ask you to read through to understand.

I am looking for BIOS updates and or dumps from BIOSes that haven't been updated since December 2016 or have been saved before January, 2017,
targeting ThinkPad T550 and/or T440. These are supposed to be TXT and/or Boot Guard enabled which is exactly what I'm looking for.
Since I do not (yet) own a ThinkPad I cannot share a BIOS dump nor do I know a serial number.

Why do I need this?
I am very interested to see a special kind of an Intel Authenticated Code Module (ACM) that is designed to run before the reset vector at 0xfffffff0.
This can be either a BIOS ACM or a Startup / Boot Guard ACM from prior January, 2017. Reason for that is, I don't want to see Converged TXT/Boot Guard technology.
Furthermore the ACM must be designed for anything lower than 6th generation (Skylake) Core i7 since the Intel ME has changed started with Skylake (ME11).
(Note that the Intel ME is an important part to running something before the x86 reset vector.)

I know I can download UEFI Capsule updates from Lenovo, but they're all too recent, and the links
which I've been checking out have either not been saved or are too recent in Wayback machine.

A quick skim of winraid forum didn't show up anything of interest either.

TL;DR: I don't have an issue and I am just looking for T440/T550 BIOSes older than January, 2017, to gain more low level insight.

Kind regards,
Microwave

P.S. The files "gjuj40us.exe" or "g2uj33us.exe" would be just as fine as long as they're older than January, 2017. I can easily extract the Capsule myself.

This bios was extracted on 2016.12.27
I hope it's good for your research...

Thank you very much.
It helped insofar as I just noticed that the Boot Guard ACM didn't change from 2013 to 2020 (date of my extracted capsule of T440).
So seems like I've had already saved that ACM.
It disproves my proposition that I could not just use the newest BIOS updates for extraction.
It suggests that Startup ACMs either don't need security updates or are too unflexible for updates since a lot of info might have been burnt onto the die.

What surprises me most is how execution appears to consistently take place in 32 bit mode, even before the reset vector (normally "unreal mode").

TL;DR:
Yes it helped and no further files are necessary.

Kind regards,
Microwave
