I searched for that driver driver too a while back, but no luck :/ anyone has an idea? Cuz this one should be useful on classic amiga systems as it's native and will need no emulation to be used = less wasted cpu time. ie I've seen that under OS4 the 8029 driver which is native can reach better network speeds vs pcmcia (and not due to pcmcia being slower) and OWB feels faster as well.
