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.

Greetings from Brazil! Not sure I'm posting in the right place, but I have a question: how do I find out the brand and model of my BIOS chip without having to open my laptop? I can't find this information anywhere. Been searching for days... I have a Lenovo Ideapad 300-15ISK 80RS (motherboard Paris 5A8). Thanks a lot for your time and help! I really appreciate it! Best regards, JC.
