BIOS/UEFI Modding BIOS Modding Requests

hi, i would like to change the bios to my gigabyte aorus 17g xc.
I would like to have the possibility to undervolt the processor and to eliminate the integrated and remove nvidia optimus that castrate my pc.
If the bios is changed, will the guarantee be lost?
Can you make a backup of the previous one?
Since it is the first time that I have done such a thing, I would be grateful if you would give me all the guides and information possible step by step.
thank you very much

ps current bios is: BIOSAmerican Megatrends Inc. FB03, 22/12/2020 and Intel ME Version:14.0, Build 1339, Hot Fix 39

Remember any bios mod is made for any single laptop, if you wiill use one for a different user then you will loose your system data like
UUID, serial,MAC, etc. so to avoid to make wrong ask before to complete the flash, further there are the Patched for CodeRush UEFIPatch Tool
to make by yourself your bios mod, based on own bios backup.
If you need help , ask and i will make all for you !

Let me know and i will help you to makie it togheter …

Here there are examples :

[Request] Gigabyte AORUS 15G BIOS unlocked

Eeprom Write Unlock Bios FB03 (your version) :

0x3E612 Setting: Flash Protection Range Registers (FPRR), Variable: 0x6DD {05 91 8B 12 8C 12 5F 07 17 00 DD 06 10 10 00 01 00}
0x3E623 Option: Disabled, Value: 0x0 {09 07 04 00 30 00 00}
0x3E62A Option: Enabled, Value: 0x1 {09 07 03 00 00 00 01}
0x3E631 Default: 8 Bit, Value: 0x0 {5B 06 00 00 00 00}
0x3E637 End of Options {29 02}

0x4AB93 Setting: BIOS Lock, Variable: 0x17 {05 91 CD 0B CE 0B 6A 0C 17 00 17 00 10 10 00 01 00}
0x4ABA4 Default: 8 Bit, Value: 0x1 {5B 06 00 00 00 01}
0x4ABAA Option: Disabled, Value: 0x0 (default MFG) {09 07 04 00 20 00 00}
0x4ABB1 Option: Enabled, Value: 0x1 {09 07 03 00 00 00 01}
0x4ABB8 End of Options {29 02}

The variables to patch , set value from 0x01 to 0x00, into this GUID 4570B7F1-ADE8-4943-8DC3-406472842384 - PchSetup :

Flash Protection Range Registers (FPRR), Variable: 0x6DD
BIOS Lock, Variable: 0x17

Once you are into RU Shell, then looking for the GUID , choice this one and get the right offset i.e. 0x17 is gave
from horizontal 0x0010 upper 0x0007 = 0x0017
the 0x06DD >> horizontal 0x06D0 - upper 0x000D = 0x06DD …

This is the FPT Tool 14, to make the bios backup and flash the bios mod :

the first is my modified BIOS link? how should I flash it?

12

The command is the same fpt used for the dump , change only the opt d = dump then f = flash, rename bios mod file as bios.bin and execute …

fptw64.exe -f bios.bin -bios

Or x32

fptw.exe -f bios.bin -bios

Let me know
Regards

fptw64.exe -f bios.bin -bios

hi and thanks for the reply, i just wish i could enable undervolt and that’s it. Before, there were so many options. And if possible disable the igpu even if unfortunately it detects me as muxless. Nvidia Optimus broke me
