Hello Marcel,

I am going to respond here as it is easier for me to upload files and keep track of ongoing BIOS mods on the forum.

Here is a list of menus that do or can be made to show up (extracted IFR text given by Donovan6000's Universal IFR Extractor):

Form: Setup, Form ID: 0x2710 {01 86 10 27 07 00}
0x3D893 Ref: Main, Variable: 0xFFFF {0F 0F 09 00 02 00 01 00 00 00 FF FF 00 11 27}
0x3D8A2 Ref: Advanced, Variable: 0xFFFF {0F 0F 1F 00 02 00 02 00 00 00 FF FF 00 12 27}
0x3D8B1 Ref: Chipset, Variable: 0xFFFF {0F 0F 21 00 02 00 03 00 00 00 FF FF 00 13 27}
0x3D8C0 Ref: Security, Variable: 0xFFFF {0F 0F 3C 00 02 00 04 00 00 00 FF FF 00 14 27}
0x3D8CF Ref: Boot, Variable: 0xFFFF {0F 0F 22 00 02 00 05 00 00 00 FF FF 00 15 27}
0x3D8DE Ref: Exit, Variable: 0xFFFF {0F 0F 50 00 02 00 06 00 00 00 FF FF 00 16 27}
0x3D8ED Ref: Main, Variable: 0xFFFF {0F 0F 09 00 0A 00 07 00 00 00 FF FF 00 17 27}
0x3D8FC Ref: Advanced, Variable: 0xFFFF {0F 0F 1F 00 20 00 08 00 00 00 FF FF 00 18 27}
0x3D90B Ref: Power, Variable: 0xFFFF {0F 0F FE 19 FF 19 09 00 00 00 FF FF 00 19 27}
0x3D91A Ref: Authentication, Variable: 0xFFFF {0F 0F 45 1A 46 1A 0A 00 00 00 FF FF 00 1A 27}
0x3D929 Ref: Security, Variable: 0xFFFF {0F 0F 3C 00 3D 00 0B 00 00 00 FF FF 00 1B 27}
0x3D938 Ref: Boot Options, Variable: 0xFFFF {0F 0F 74 1A 75 1A 0C 00 00 00 FF FF 00 1C 27}
0x3D947 Ref: Exit, Variable: 0xFFFF {0F 0F 50 00 51 00 0D 00 00 00 FF FF 00 1D

As you can see, there are copies of several menu names. Some manufacturers create a watered down version of a menu for consumers and leave the more feature-filled version of the menu hidden. For this mod, I will be ensuring that the Main1, Advanced1, Chipset, Power, Authentication, and Boot Options parent menus show up. Which parent menus can you currently see?

EDIT: Moving this thread to the AMI BIOS Unlocking Requests forum.

Alright, thanks for the info.

I am having some troubles repacking the modified BIOS image with UEFITool. I'll keep working on this. Hoping that I'll have a BIOS mod ready tomorrow for you to test out!

Hello Marcel,

I have a BIOS mod ready for you to test out. PhoenixTool 2.73 did the trick for successful re-integration.

I did manual edits in the AMITSESetupData module to change the required access level for the hidden menus. No "magic string" or FormID Block List edits were made in the Setup or AMITSE modules as those hiding techniques did not appear to be implemented. We will see if this is enough to unhide the menus.

There are several ways that we can go about flashing the modified BIOS image.

We will try them in this order:
1.) AFUEFI: This is the simplest safe method.
2.) AFUDOS: This will require using RU.EFI to change a hidden setting called "Boot Filter" to "Legacy BIOS" to allow booting into a DOS environment.
3.) AFUWIN: This is the easiest method, but Windows-based flashers have a higher brick rate (still incredibly small though). Your machine can be recovered from a brick using a CH341A SPI Programmer because we have a full (all regions) backup, but we still want to minimize the chance of a brick.

For the AFUEFI method, please follow the following:
1.) Format a USB Flashdrive as FAT32. This will erase all files on your flashdrive. Follow these instructions: https://www.easeus.com/partition-master/format-usb-flash-drive-in-windows-10.html#part2 BUT DO NOT TICK "QUICK FORMAT" in Step 3. We do not want to do a quick format.

2.) https://github.com/chipsec/chipsec/raw/master/chipsec/modules/tools/secureboot/Shell.efi Download this file. It is a UEFI shell. Create the directory /efi/boot on the flashdrive and then place the Shell.efi file there. Rename it to "bootx64.efi".

2.) https://www.ami.com/download/aptio-v-ami-firmware-update-utility/ Download the ZIP file. It contains AMI Aptio V flashing tools. Within that archive, navigate to afu>afuefi>64>AfuEfi64.zip>AfuEfi64> and extract AfuEfix64.efi to /efi/ on the flashdrive.

3.) Place the modified BIOS image in the /efi/ directory on the flashdrive.

You should now have the following three files on the flashdrive:
/efi/boot/bootx64.efi
/efi/AfuEfix64.efi
/efi/mod.rom*

*Substitute "mod.rom" with the name of the modified BIOS image.

4.) With the flashdrive inserted into a USB port, reboot your computer and enter the BIOS Setup Utility. Set the computer to boot from the USB flashdrive.

5.) Once you boot into the EFI Shell Environment, run the following commands:
fs0:
cd efi
AfuEfix64.efi mod.rom

Let me know if this works. If you encounter an error, write down *exactly* what it says or take a picture of it and upload it here.
