I have been reading the pinned post and been reading related post from searching, but I think I have ended up with information overload, and I seem to be missing something simple.
I have a Dell OptiPlex 7070 with ME disabled. I managed to add a jumper to the service mode pins, and things seems writable now.
I dumped the entire image with fptw64 -d full.bin, and I opened it using Flash Image Tool, and was greeted with basically all of the AMT parameters set to “no”, which was expected.
I switched them to “yes”, and set “Manageability Application initial power-up state” to enabled, and then i tried to build a new image, but was greated with the following:
FW image for FW Update was not created. See deatils in: C:\Users\...\Downloads\Intel CSME System Tools v12 r22 [FPT_LINUX_SUPPORTED]\Flash Image Tool\WIN32\cse_image_FWU_Base_WARNING.txt
FW image for FW Update was not created. See deatils in: C:\Users\...\Downloads\Intel CSME System Tools v12 r22 [FPT_LINUX_SUPPORTED]\Flash Image Tool\WIN32\cse_image_FWU_Full_WARNING.txt
Both the full and the base text file contained the same information:
** WARNING ***
FW image for FW Update was NOT created!
Reason: CSE FW from a decomposed IFWI image was used.
Action to fix the situation:
To have the FW Update image created, use the original Intel CSE image included in the ME FW Kit as released by Intel.
It did create an outimage.bin file with a different md5 hash than the full.bin I used as input. But when opening theoutimage.bin file the changed AMT settings are not present, which was kind of expected given the error.
So, this is where my information overload comes in, reading all those pinned comments. I have no idea exactly what to do, as reading those posts seemed to indicate that I should be able to open my own image file and modify it and flash it without cleaning it and messing with generic images?
