Argh.

Well, I'm no expert for Sheeva plugs, but most ARM processors have some
kind of Ur-Loader implemented in internal ROM, which can be used to load
something from e.g. a serial connection, an SD card, or even a USB
connection.  So you may well be lucky as not to need any more hardware
to revive your brick ;)

So I'd suggest to get the CPU documentation and find the relevant parts.

Cheers
