[h1]Wifi card whitelist[/h1]
[p]All thinkpads have a Wifi card whitelist at the BIOS level that prevent installing certain WiFi cards. The restriction can be bypassed with a BIOS modification: either installing Libreboot, Coreboot or editing the official Lenovo/IBM BIOS.[/p]
[p]Tested with LiveCD. Bluetooth works on startup. All multimedia keys work on startup except for microphone mute. This includes screen brightness and keyboard light.[/p]
