Connecting the 9 Axes motion shield and the Wireless SD Shield?

Hello! I am trying to attach both of the aforementioned shields to my arduino uno. Before purchasing I tried to find which pins the shields used for data communication to no avail. After receiving the parts I attempted to use them both at once with no success. After some searching I found this Arduino - Home compatibility table. According to the table, the two shields are compatible only after, "moving the 0R from D4 to D3". How would this be done? Is the move for the pins on the wireless sd board or the 9 axes board.

I'm not clear on what the OR even means?

Looks like the comment was in the 9-axis board entry.. so I would 'assume' that is the board that needs the change?

OR might be the same as a CS pin? (done in the sketch?)
