[Soekris] Suddenly, no boot device available :(

[E S]

So I just returned from a wekk long work trip, during which I had shut 
everything down at home, including the UPS which powers my Soekris 4521.

Turning everything back on, with ethernet cables disconnected, I get the 
following:

Noticeably, the CF device is not appearing. I have never configured my 
system for PXE boot. Lately I've been using monowall. I swapped in another 
CF card with an OpenBSD image and same result.

Any troubleshooting advice? I don't pay much attention to my 
Soekris--usually, it sits happily in its corner and Just Works. If this is a 
hardware problem, does Soren even take these back for repair? I don't see 
any mention of this sort of thing on the website.
