Hello,

Please help me unlock all hidden options in the BIOS. I would like to enable CSM and undevolting abilities along with other hidden settings relating to performance.

I have disabled BIOS Lock and FPRR by using RU. With AMIBCP, I changed the Access/Use option to Supervisor (then to User after the first try) for some settings. Flashed the modded bios with FPT, booted up but nothing has changed in the bios menu.

BIOS dumps with FPT & menu screenshots: https://mega.nz/folder/1WhhHYBL#vQkYHRayuNDQHNc9HbVBKQ

Exact Model: FX506LU-HN138T
BIOS 309: https://www.asus.com/us/supportonly/FX506LU/HelpDesk_BIOS/

Thanks in advance.

Please help!

Try this mod and respond to the result.(it's modified based on notvisible_modded.rom)

Hi @genius239

I tried it and 3 tabs appear next to the original ones: Main, Advance and Chipset.

@Minoun

Yes ,this result was i expected , i only unlock three new tabs ,they contain most features ,so i choose unlock them.

Now i'm go to sleep ,good luck!

@genius239

Thanks for the unlock!

Could you explain how you did it, please. I have been trying to recreate your mod using unlocked.rom as a base.
I have edited the AMITSE PE32 module and change Access Level to User according to this guide by Lost and your mod but the menus are not visible.

Attached my notes for the edit.

Hello guys! I have the Asus FX506LU-HN011 laptop with 309 vanilla BIOS version onboard. I want to unlock some hidden features (especially - undervolting). Is this modded BIOS version is right for my laptop?
Thank you very much! Hope for your responce.

@Lucious

First make a bios dump with this tool then attach ,i'll check it and make a mod for you.

@genius239
Thanks for the instruction. Here the dump: http ://drive.google.com/file/d/1km4gKG4NfnRMkohxhBRf2JKKiSJM-HkT/view?usp=sharing (please insert "s" after "http"). The forum doesn't pass external link cause I'm newbie here :)

Unfortunately I can't reply to the private message (may be because there are some restrictions for new accounts).
So I done all of steps that you sent me. I didn't get any errors. Only "FPT operation successful" in the end. After reboot there are many new options in the BIOS interface and FINALLY undervolting function became available (ThrottleStop and XTU)!!
Thank you very much! This is a kind of magic! :D

@Lucious

You're welcome ~i'm glad i have helped you out.
Now i'm gonna sleep(now is 01:33 A.M) ,good luck!
