What's the easiest way to read/write to my laptops bios chip?
#1
Hello, 

I have a Samsung NP270E5E-X02AU laptop. I'd like to unlock the advanced/hidden options in the bios. Is there a way to read/write to the bios chip so I can do this?

The bios chip on the motherboard reads "winbond 25Q64CVSIG1328". I've tried using a CH341A programmer, however, have had no success. I've read on some forums that because it outputs 5V it's not compatible with my motherboards bios chip (runs on 3V), and that there are mods you can do to the CH341A to remedy this. I did one mod, and it still did not work. 

Is there a method to achieve what I want without have to do modding/soldering etc? If it requires purchasing another tool, I'd consider it, depending on the price.

Thanks!
