A kinetic ballooning mode equation retaining full finite ion Larmor radius and ion magnetic drift resonance effects is derived by employing the high n ballooning mode formalism. It is found that the critical ..beta.. is smaller than the ideal magnetohydro-dynamic critical ..beta.., except that when eta/sub i/ = O(eta/sub i/equivalentd ln T/sub i//d ln N), that are identical. The finite Larmor radius effects reduce the growth rate but do not stabilize the mode. The ion magnetic drift resonance effects are destabilizing.
