This will take ages (2 minutes)! If you want a
status bar: Attach a serial to the device and look there.
Note: If this fails, you need to use AVM\' recover
utility to get your box back. However this step
should not damage your box....
Also it doesn't terminate.. :/
(Note: Make sure that you connected the router on
the yellow LAN ports and not the blue WAN).
