I have a Rev C BeagleBoard xM and I would put a boot image itself.
From what I've found online it seems that in earlier versions if that
was possible but not in this (http://groups.google.com/group/
beagleboard/browse_thread/thread/30d5fe37ade44b8/f1e73fe5023ee3d1?
lnk=gst&q=splash#f1e73fe5023ee3d1). Anyone has managed to customize
the splash screen?
