[Request] Dell Latitude 7414/5414/7214 Rugged Extreme Bios v1.26 Unlock HiddenMenu


I’m doing the first step to do this, but i’m a little bit annoying to do some step to unlock the hidden menu.

I’ve extracted the Section_PE32_image_Setup_Setup_body IFR from the bios V1.26

The latest bios :


The bios have a Biosguard, i suppose i need to dump with a eeprom programmer and flash the futur modded one with it too.

I join the setup body extraction.

Hope someone can help me

Regards, Ray.

Arf… i look if Lost’N SantaClaus leave me a “present” But nothing for the moment


This is my extracted bios with DeLL PFS Bios Extractor V4.6

Do you need absolutely the Raw Dump ?

Hi :Op

Soldered my ZiF socket. Dump Done.

@DoZe - So you added the socket above? If yes, nice work

Please download V11 ME System tools from this thread in section "C.2"
Intel Management Engine: Drivers, Firmware & System Tools

Then from MEINFO folder run this command and show me image of the bottom of the output >> MEINFOWin.exe -verbose

Hi :O)


Yep, i add the zif socket myself. A little bit difficult on 5414 Mobo, i admit.
