[REQUEST] Acer Aspire V3-772G BIOS Unlock

[Da Vinci Code]

Hello!
I can extract vbios module so you can modify it yourself.
There are no useful options in Advanced tab.
Regards!

Thx for reply, what I need to do?
I think voltage menu is a great option if it has in Adv bios, cuz CPU is very hot for 772g cooling system

my BIOS Backup http://rgho.st/6k24shBFZ
Can I use MaxwellBiosTweaker to edit extracted vbios module and flash it if vbios module is a part of main bios?

I understand a little bit how it works:
1. Use Universal Backup Tool Kit 2.1 to extract bios
2. Use UEFITool to find SetupUtility section in extracted bios .bin file. Sefe that section
3. Open saved .fbd with Universal IFR Extractor.
4. Setup utility module .txt file done.
5. Use this post to change your BIOS settings https://www.bios-mods.com/forum/Thread-R...3#pid56913
6. If something go wrong out battery and motherboard +5V battery to default BIOS settings

But I can't understand how to turn on the entirely Form Set on.
For Advanced tab i need use setup_var 0x159 0x1 ?
And for Power tab i need use setup_var 0x378 0x0 ?

Hidden tabs settings are not presented in your bios setup.
You can change each option manually.If you will brick laptop after some changes so you can easy restore settings by clear CMOS.
For example, i found this fan option in your laptop
Setting: Critical Thermal Trip Point, Variable: 0x198
Option: Disabled, Value: 0xFF (default)
Option: 15 °C, Value: 0xF
Option: 23 °C, Value: 0x17
Option: 31 °C, Value: 0x1F
Option: 39 °C, Value: 0x27
Option: 47 °C, Value: 0x2F
Option: 55 °C, Value: 0x37
Option: 63 °C, Value: 0x3F
Option: 71 °C, Value: 0x47
Option: 79 °C, Value: 0x4F
Option: 87 °C, Value: 0x57
Option: 95 °C, Value: 0x5F
Option: 103 °C, Value: 0x67
Option: 111 °C, Value: 0x6F
Option: 119 °C, Value: 0x77
Option: 127 °C, Value: 0x7F
As you can see, default means current value, it switched to Disabled.But you can change this
setup_var 0x198 0x27 (Example)
I have shown you free way how get access to hidden settings.You can make request to unlock hidden settings in bios setup permanently but your top can be stay without reply (i dont modding confirmed bios requests)
