Unlocking the BIOS

1. Make sure you are currently running the A06 BIOS. If you are using A07/A09, pay special attention to the note regarding the TPM Security SSDT in the "BIOS Configuration" section.

2. You'll also need the following tools:
   AMI Flash Utility
   UEFITool
   HexEdit

3. Use AFUWin64 by navigating to Aptio\afuwin\64\afuwin.zip, and save your current bios to a ROM file.

4. Open the dumped bios in UEFITool, expand the sections one-by-one and scroll down until you find Setup in the Text column.

5. Right click on the Compressed Section just below the DXE Dependency Section, and select Extract Body, save this as setup.bin (~474 kbytes).

6. Next open setup.bin in HexEdit and search for 01 01 00 01 01 01 01 00 00 00.

7. Change the last three 00 to 01 so that you now have 01 01 00 01 01 01 01 01 01 01 and save as setup_patched.bin.

8. Go back to UEFITool and right-click the section you just extracted and select Replace Body, select setup_patched.bin for replacement, and then save the resulting ROM file to bios_patched.bin.

9. Open a command prompt with administrative rights and execute: afuwinx64 bios_patched.bin /GAN. Reboot, and enter the bios setup via F2 and verify you have the new unlocked menus.
