[Help please] Dell Optiplex 7090 - Enabling Intel ME

Special Topics Intel Management Engine

Good evening,

I know this is an old thread, but I believe it holds the key to helping me with some Precision 3450’s.

I have the same issue as the OP. There is no BIOS option for MEBx under “SYSTEM MANAGEMENT”. It appears to have been factory disabled.

I dumped the BIOS from the Precisions and compared them to a relatively similar set of machines, some Optiplex 7090’s. With both firmware dumps, I get the same error in FIT… Error 179: [Fit Actions] Failed to parse CSE region.

I can open and unpack both firmwares in ME Analyzer. The optiplex’s have full working AMT and the MEBx settings visible in BIOS…

MEA shows that EFS 0000 [0x410000] > “DISABLE_MANAGEABILITY_HW (0010)” file has value 1 for the Precsions and a 0 for the working Optiplex’s.

Trying to follow along on this OP’s journey, I see he figured the last part out on his own… Somehow replacing the EFS so that he could open the dumps in FIT…

Where and how can I either make the change to “DISABLE_MANAGEABILITY_HW (0010)” and repack the firmware or how do I get past the FIT error?

Thanks in advance. :slight_smile:

Post a link to or attach a firmware dump of the Precisions

I was able to do a little more reading and found another threat where you helped someone else out in this situation. I followed that advice and was able to replace EFS in my dumped bios image. From there, I ran it through FIT and it worked!

Thank you again!
