Lenovo ThinkPad T540p

Installation
Since the Minimal Installation CD does not come with the necessary firmware to use the wireless networking controller you will be forced to use another live system, if you are planning to establish a wireless lan connection during installation.

Wireless

Installing the firmware
When installing the firmware you can either choose the hardware specific package or the general package.
