[coreboot] Postcode at Lenovo x230

[Rafael Machado]

Hi Eli

Thanks for the answer.

In fact I already tried this, but didn't work.
What I am afraid is the possibility of having bricked the system by using
the postcode at the wireless card slot.
Any idea if this could have happened?

Thanks
Rafael
