* Booting GNU Linux 4.9 from USB using SeaBios
* Native GFX init
* All Fn function keys
* Speakers
* PCIe Wifi
* Camera
* WWAN
* Fan (Dynamic Thermal Managment)
* Flashing using internal programmer
* Dual memory DIMMs running at up to DDR3-1866
* AC events
* Touchpad, trackball and keyboard
* USB3 ports running at SuperSpeed
* Ethernet
* Headphone jack
* Speaker mute
* Microphone mute
* Volume keys
* Fingerprint sensor
* Lid switch
* Thinklight
* TPM (disable SeaBios CONFIG_TCGBIOS)
* CMOS options:
