Robert I tried read the value of the memory in grub, but didn't work very
well.
How I can get the value of the adress 0x000ffa17  and put its on pointer.
I am sorry but I need help.
How i make this?

I tried this code, but I have some errors, I define the variable but
didn't resolve, the people of the clevo notebook make the especial BIOS to
me,and I need get this value and make the logical comparation!!! Could you
help me? Don't me alone with this problem. I already said before, If
necessary I will pay, It's very important to my company resolve this
situation. My time is over now.
