I don't have a HPNA card to test with and don't really want to send HPNA on my filtered DSL line.

I just tried this out.

If I hit the power button really fast like ten or twenty times I can sometimes get it to boot up with the LINK LED solid green. It gets an IP address from my router but it always give me the "LOOKING FOR MUSIC SERVER" message on the display. It never finds the music server and times out with the IP address that it received from the router. If I ping that IP address from a PC connected to the same network I get a response back from the RIO. I think the RIO is going nutty (technical term).
