HP 840 G6 BIOS - switch ON the MPM mode

[Kazik]

Hi,

Can you turn on the MPM (Manufacture Programming Mode) in this BIOS, please? Yes I need this BIOS in MPM mode.

Eventually is there any tool to find MPM settings in BIOS (tool that can work with BIN files)?

I know where that HEX is in 8MB BIOS but have no idea where to look for it in 32MB BIOS.

Thank you.

HP 840 G6 MPM (Manufacturing Programming Mode) turn on

Can Someone indicate tthe procedure to Turn ON the Manufacturing Programing Mode) so as to am,end the DMI

I have tried with the BCU urility by changing the star "**" from "Lock" position to "Unlock" position without any positive result.

I understand that changes in the BIOS (by using the BCU) are only possible if the MPM is in Unlock condition

If someone has different knowledge please post the experience gained.

How did you edit the BIN file to enable MPM? I am trying to do it myself.

Hi, did you find out how to edit the MPM to UNLOCK?

[alfanikos]

NO I have not done anything. I gave up . I have searched and stopped. The BIOS MPM remained as it was originally without any changes. If you find something just drop me a message (just form my information)
