A busmastering device has 2 notches in the edge connector. To take full
advantage of the mastering abilities, it needs to be in a busmaster
slot, which has of course 2 keys (a non-busmaster card won't fit into
it), but my experience has always been that without a busmaster slot
available, things always seem to work better if the busmaster card is in
slot 0.
