[Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization

How to put?

@Mickeytang
The ME firmware is missing in the file you dump by the SPI.
Hi,Iā€™ve made it for you with the latest ME firmware and NVME supported,you could flash it by Programmer or other method.

Hexeditor. Append bios region to the end of your other/ first dump. Check results with UEFItoolNE.

PC does not turn on when i flash outimage 4mb piece, but working with my dumped file, only too long start.

@Hai_kkk Without explaining what you did and posting the corresponding files itā€™s impossible to comment.


Np, i glued both files, first 4mb then 8mb, after i opened it with intel FIT and replaced me region with clear one from repo. After building there are 3 output image files, 4 8 and 12mb, so with that 4mb file my pc will not turn on, but it works with old one, only too long start.

Only thing off is the MAC Address but i can fix that.

Thank you!

@Mickeytang

Hello,I first throw the file into the FITc and it will prompt the error"configuration parameter size mismatch".

MOBO:Asrock B75M-ITX
BIOS version:2.00(official version)

And I found the ME is 5MB size different from another B75/H77 chipests of ASROCK(1.5MB).But I think itā€™s not the point of the problem.
Could you tell me how to solve it?Thanks!


Read the WARNING document at Flash Image Tool folder

@plutomaniac
Thanks!I tried to open the bios file with FITc v8.1.10.1286,and it prompted no error.
But when I opened the FITc again after replacing the ME region file,the same error prompted again.

edit:
The ME region file I chose to replace is the latest version:8.1.72.3002_5MB_PRD_RGN.bin
I tried to choose the other version and found that itā€™s OK when I chose the ME version file older than the one (8.1.10.1286_5MB_PRD_RGN.bin).
It prompted the same wrong massage when I choose the ME region file newer than it(8.1.10.1286_5MB_PRD_RGN.bin).
So if Iā€™m going to update the latest ME version,how could I do?

Hello,

I have a problem when I use Image Flash Tool, it doesnā€™t work and turns off for no reason!

I followed all the first steps, I put the ME Analyzer screens with the original backup bios / ME extract from this bios (with UEFITool ā†’ itā€™s longer than it should be ??? ) / an the good ME in files in your tutorial.

I have exactly the same problems with a T460 ā€¦
If you can enlighten me?

Why are you using FIT v14 for CSME 14 firmware on your CSME 11 dump?

yes iā€™ve seen it was my problem for FIT :wink: iā€™ll test tomorrow and for the lengh of ME Extract ?

Itā€™s normal, all leftover SPI image space is appended to the Engine region by default.

Hi, itā€™s good iā€™ve a correct (i think) Outimage.bin configured iā€™m at the end (step15) but now i must insert it in bios.bin to replace the original ? How i do ?

Thanks

You can use UEFITool v0.xx releases

Ok iā€™ve an error with UEFITool : ā€œFunction called with invalid parameterā€ i think i should insert octet because the size is not the same but how i do it with HxD i see your print on the step 15 but i donā€™t understand, sorry

EDIT : I think itā€™s good now for the size i 've injected it with UEFITool but after flash the laptop donā€™t turn onā€¦ omg !

And i canā€™t link my googledrive bios file.bin (i can send it in mp) ā†’ number of message and link
