Sorry, I have realized later the loadbios setting applies only to some
ancient intel chipsets given the protect bits..
I see an equivalent in AMD BKDG, fixed MTRR, however, reading the
specific MSR freezes GRUB shell. I can read MSR in ubuntu and it sets
the memory space as write protect too.
What should i do to be able read write the MSR in GRUB, and how to
proceed with writing to the vbios memory space?
