Rescue system for Pogoplug E02 - Best Option? (1 reply)

Greetings, I have a pink Pogoplug E02 which is running Debian from a USB Drive.
It will not boot without the USB installed. Here is the boot log (booting without USB):

Wrong Image Format for bootm command
ERROR: can't get kernel image!

I'd like for the Pogoplug to boot some O/S with the USB removed.
I have no image for the original O/S, so that's probably not an option.
Rescue v2 looks good, but I am not sure it is compatible with E02.
What is the recommended rescue systen for E02?
Thanks for these forums and your wisdom (couldn't have gotten this far without help from this site).
