[PSA] Lenovo ThinkPad L520 BIOS mod for Wifi-card AR9285 remove whitelist


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)


As the installed intel centrino wireless card did not work with OSX I bought a very cheap ( <5€ ) Atheros AR9285 mini pci card.?


The site bios-mods.com has many solutions for problems like this. This is a link to the forum topic:




This link is for the file download:




Worked great for me, never again a whitelist. I can install any wifi or wlan card now.


I put the files into the download section.
