You don't need to run windows for that, the nvram (calibration data,
probably the MAC address and related device specific data) is stored
in your mainboard's firmware - and exposed to userspace (under linux)

file and copy it to a place where linux expects to find it

Thanks for the hint, that did it, I'm online!
Apparently my hint was not clear enough. Good to hear it works for you.
Dear Arend,
would be nice, if you could make it clear.
I am in the exact some position (asus x205 with linux 4.0 rc3) but my
/sys/firmware/efi/efivars/ is empty. I am running debian jessie with a
kernel taken from ubuntu. Am I missing something? Even loading efivars via
modprobe doesnt change a thing.
Maybe you need to mount it. This is what I found [1]:
$ sudo mount -t efivarfs none /sys/firmware/efi/efivars
Regards,
Arend
