Does this board have write-protect jumpers for the Flash? Most of the other
MVME boards do, but I can't get to the hardware documentation for the
MVME5500 right now on the Emerson website so I can't check that for myself.
If it does they should at least be able to prevent the flash from getting
corrupted when things go wrong.
