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

Hi.

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.

Hi.

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

Do you need absolutely the Raw Dump ?

@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

@Lost_N_BIOS

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