For any nonsimply laced Lie group G and elliptic curve , we show that the moduli space
of flat G bundles over can be identified with the moduli space of rational surfaces
with G-configurations which contain as an anticanonical curve. We also construct
Lie(G)-bundles over these surfaces. The corresponding results for simply laced groups
were obtained by the authors in another paper. Thus, we have established a natural
identification for these two kinds of moduli spaces for any Lie group G.
