[Request] Dell Optiplex 3090 MFF with Enabled ME /vPro

I have a Dell Optiplex 3090 MFF i5-10500T (chipset Q470) with AMT state 3 disabled.
I want to turn AMT on but I cannot dump my bios because there is no service jumper like in many other older dell PC’s.

Motherboard in service manual with jumpers


My motherboard is different. It is Foxconn IPCML-RN/ZB without any jumpers:


In older models service manual has a notice that:

Nowadays there is no RTC reset jumper, no password reset jumper and no service mode jumper.

Is there any way to turn the service mode on? Maybe I should short 2 unsoldered pins near CPU FAN socket, but I do not have motherboard scheme.

Thank you in advance for any suggestions.

Since your problem cannot be solved without a modification of your mainboard’s SPI BIOS chip, I have moved this thread into the “BIOS Modding Requests” Sub-Forum.
Good luck!

Hello, do you have any news about this topic, becouse i have the same issue.


You have to use programmer and do some modifications in BIOS dump.
I bought SOP16 test clip and use CH341A programmer
Here is the clip pinout in relation to SOP8
