  2. As root extract the image onto your SD card (replace sdX with the device name of your SD card).
    WARNING: all previous data on the SD card will be lost. Check first if the device you have selected is really your SD card!
     xzcat [image].raw.xz | dd bs=4M of=/dev/sdX iflag=fullblock oflag=direct; sync
  3. Insert the SD card with the openSUSE image into your board.
  4. Connect the board to your PC via serial port (optional, but helpful for debugging; USB-TTL serial cable needed).
  5. Connect the board to your monitor (via DVI/HDMI, optional).
  6. Power on the board.
  7. Walk through the first boot steps.
  8. Ethernet is configured to request an IP via DHCP, check your DHCP server for the board IP if used.
  9. Have a lot of fun...
Default login is root:linux, works on serial console, via ssh, GUI.
