3DSMAX (export to) ->> XNA 3.1

How do i put bones and skin on an atom so that i can export the animation into xna 3.1.

The problem being everyone uses skinning sample but that's for bipeds and skin and bones fuck up my atom animation.

Are bones and skin the only way to go for exporting my animation?

What xna library do you use that doesn't require bones?
