		Hello BDMASTER,
I know this is quite old thread, but I have also the same problem. I have Lenovo E540 and desperately need to change Wifi Card to a AC/dualband one. My bios is older - J9ET88WW (2.08) . Link to files need to "read" the bios are non active, so I can not provide data right now for your investigation. Is there any way to help please?
