===== Notes =====

  * The docks USB ports work right out of the box;
  * The docks Video requires **graphics/drm-kmod**;
    * In case you encounter kernel panic when loading the i915kms.ko module add the following to your **/boot/loader.conf**

<code>
kern.smp.disabled=1
</code>

  * Wireless seems to work with this settings added to **/boot/loader.conf**:

<code>
if_iwm_load="YES"
iwm8265fw_load="YES"    
</code>

  * Suspend/Resume seems to work from X, if you disable TPM in the BIOS/UEFI;

Updating the firmware is possible after converting the ISO image to a bootable .img to use with an USB stick, using **sysutils/geteltorito**:

<code>
# geteltorino -o bootable.img bootable.iso
</code>

Overall impression so far:  Good, would recommend to current-running hackers.

Untested: Camera, Microphone, Fingerprint reader, Smartcard reader, SD-card reader.
