how do i bring a archos 101 back to out of the box state

Try this:
Power your Archos 101 off by holding the Power Button for 10 seconds (this fully shuts it down).
While holding the Volume + button power it back up (tap power button to start up, hold volume until the tablet enters recovery mode, you'll see a series of choices instead of the demo mode).
Choose the Format System option.
When this process is complete make sure not to select Demo Mode as Android boots and the Archos 101 gets up and running.

Archos support is correct, if it doesn't use a simple interface like a hard drive or mouse/keyboard, then it won't work on the Archos 101.
Manufacturers aren't releasing Android drivers yet for the most part, so I wouldn't expect an ethernet to USB cable to work any time soon, sorry!

Hold the (-) volume button for a few seconds and then power button at the same time
