[ASK] Hidden Menu (Advanced)

[boaksoo]

Hi All,

This is my first time trying to edit the BIOS.
I'm trying to modify an BIOS (Phoenix SecureCore Tiano) to show up a hidden menu (Advanced).
Here is following the steps :

1. Open latest BIOS (JE40124.WPH) using UEFITool


2. Find "PlatformSetupAdvanced" and found in CFEF94C4-4167-466A-8893-8779459DFA86


3. Extract using Universal IFR Extractor


4. After that, in CFEF94C4-4167-466A-8893-8779459DFA86.txt I found "0x2D8B1 Default Store: Standard Default - Advanced 0x0 {5C 06 0D 03 00 00}"


Display in HxD :



Question 
1. Is it correct that the file I will edit? 
2. If correct, do I have to change 0x0 {5C 06 0D 03 00 00} to 0x1 {5C 06 0D 03 00 00} to show the hidden menu?
3. If wrong, is there another way to show up the hidden menu? Please tell me.

Here is my latest BIOS :
