About This File

My Lenovo L520 had a whitelist which stopped boot with the error:

"1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card (1199/0218)" (or something similar)

The first file removes the whitelist check in the Lenovo L520 BIOS

Backup the old BIOS first, then just flash the BIOS in Windows.

Shut down Windows.

Install the new mini pci wifi/wwan card (I chose the Atheros AR9285)

Check if the BIOS still stops with the whitelist error.

Boot into Mac Osx (I got 10.8) run the ar9285 package.

Reboot

Now you should have a running wifi card.
