A coupled system of linear integral equations are derived from the electromagnetic gyrokinetic equations and solved in straight and sheared slab geometries. Simulation results of a finite-[beta] modified ion-temperature-gradient-driven instability in a sheared geometry are presented. It is shown for typical tokamak parameters that the fundamental [ital l]=0 slab mode can be completely stabilized at [beta][approx]1% while the [ital l]=1 slab mode persists.
