[Help please] Dell Optiplex 7090 - Enabling Intel ME

Hello all, I have two Dell Optiplex 7090s. One has Intel AMT Enabled, one has it disabled. I would like to enable Intel AMT on the second PC. Posts on this forum suggest that a good way to start investigating is to get an image of the I2C ROM, use the Flash Image Tool to enable AMT in that image then flash back. (I have a programmer to bypass the locks of updating from software.) I believe the programmer is reading the ROM consistently (checksum is the same until I power on the PC), and MEA re…

[Help please] Dell Optiplex 7090 - Enabling Intel ME

Alright, for some reason, FIT refuses to work with the initialized/dumped SPI images, even though they seem healthy when checked/unpacked via ME Analyzer (MEA). The only way to get them to work with FIT is to manually clean their initialized File Systems (MFS, EFS) by replacing those regions with the same stock ones. I used 15.0.22.1595_COR_H_A_PRD_RGN for “no-AMT-1” and 15.0.35.1951_COR_H_B_PRD_RGN for “with-AMT-1” because they include the same initial/stock MFS and EFS partition hashes. Now,…

You can take EFS and MFS from ME update of latest bios update for DELL 7090, 15.0.41.2158 Corp H isn’t part of the repository yet.

Thanks！
The post said"manually clean their initialized File Systems (MFS, EFS) by replacing those regions with the same stock ones.",Can you tell me the detail?I unpacked the bin file and get efs and mfs,can you tell me then what to do？ I found the 15.0.41.2158 Corp H file like follow.
efs&mfs.zip (309.7 KB)
CSME 15.0 COR H B v15.0.41.2158.rar (5.4 MB)
7090mff_bin_html.zip (1.0 KB)
I unpacked the CSME 15.0 COR H B v15.0.41.2158.bin file, get the efs/mfs, copy and replace them in 7090mff.bin,and then how to package to one file?

For the bios dump use a hex editor, Start address and length of MFS EFS via UEFIToolNE.

[goodmail1]

Thanks for your reply.
I use UEFIToolNE to found the start adrress[00410000] and length[00010000]
FPT partition | Data | 00410000 | 00010000 | ABDD254D | — EFS
But I don’t know what to do after this…
I will looking for the method to replacing EFS region.
Thank you anyway…

Delete the block in firmware
Select all in the stock EFS (Ctrl-A)
Copy (Ctrl-C)
Paste into firmware at 0x410000, cursor should still be in right position

Should be enough with EFS!

Really appreciate of you!According to your method, I succeeded！After do that, Fit will no error messag

I using [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization - Intel Management Engine - Win-Raid Forum method and actived intel AMT(Vpro)!

But I use ME analyzer check outimage.bin,got the following results.The file system state do not show “configured”.

But no influence,I flash it back to mainboard and succeeded!
Is it necessary to run [fpt -greset] command?
Thanks for your selfless help!
It is because of you and other selfless people that this community is so popular!

Dear Sir How You Unpack the Repository Bin File

[goodmail1]

Hello,I use HXD editor(https://mh-nexus.de/en/hxd/).

@tuyen821991

Can you guide me on how to extract the efs&mfs.zip file from CSME 15.0 COR H B v15.0.41.2158.rar without a video, if possible?

Use MEA with -unp86 option (you have to use it on the uinpacked binary of course)
