To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
How can i solve this problem ?
please help i can't access my g5070's advanced menu
I would love to have my BIOS modded to disable the wireless whitelist.
I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.

(EXP GDC Beast v8.4d mPCI-E + GTX970 + ATX PSU) eGPU project for Lenovo IdeaPad Z710, i7-4700MQ, 16GB RAM, SSD, GeForce GT745MBy damianalex
I want to show you my new project.
I bought my laptop about 5 years ago. It was never speed deamon, but for every day use, it was enough to me.
Nvidia GeForce GT745M
512 SSD Adata SU800
Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
So I make a decision to buy external grahpic card.
I choose GTX970 and now I am looking for occasion to buy it.
I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.
I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
1) unlock bios
2) buy GTX 970
3) enjoy Witcher 3!
BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
1) laptop on table, playing GTA V 1080p
- first minute (GPU core 1045MHz)
-after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)
2) with thermalpad Glacier NC400 SilentiumPC
- 30 minute and longer (GPU core drop to about 900MHz)
3) without down case of laptop (like on picture with thermal paste) on thermalpad.
Here laptop never drops down MHz and max temp are about 72 Celsius degrees.
Bacause of that I bought second down case for my laptop and I will cut there additional holes.
I will describe next step when I get all stuff I need!
