Arrange all 8 chess pieces of one set (no pawns) on a 5x6 board so no piece attacks another. Never mind that they're all the same color--it's "friendly fire". Be sure that the two bishops are on opposite-colored squares. There are 6 ways, not counting reflections and rotations.

Here's the two I figured out.  I didn't have time to work any more on it. K=King, Q=Queen, B=Bishop, R=Rook, N=Knight

Solution #1

Solution #2
