BIOS/UEFI Modding BIOS Modding Guides and Problems

Hello guys,

I was trying to mod the BIOS of my motherboard, was using AMIBCP v5.02.0031 and hierarchically unlocking some options.
Used USER and SUPERVISOR for those options, saved the rom and flashed it via MSi M-Flash but the options do not unlock.

Do I need to do something more? If yes can you guys point me in the right direction on how to?

Thanks in advance.

Have a great day!

Share the mod to take a look, no promises of more progress.

Hey @MeatWar ,

Thanks for answering.

I was only trying to open the following options:

Root > Setup > Settings > Advanced > ACPI Settings (for Modern Standby).
Root > Setup > Settings > Advanced > Integrated Peripherals (for HPET).
Root > Setup > Overclocking (CLDO_VDDP voltage).

I was using the original file from MSi and editing it, maybe it is the problem, I can try to use flashrom tool to do a raw extract and flash the mod and see if it works.



The modded file is below @MeatWar , if something is missing can you please tell me?
