  We describe a first attempt to calculate scalar 2-loop box-functions with
arbitrary internal masses, applying a novel method proposed in hep-ph/9407234.
Four of the eight integrals are accessible to integration by means of the
residue theorem, leaving a rational function in the remaining variables. The
result of the procedure is a three- or sometimes two-dimensional integral
representation over a finite volume that can be further evaluated using
numerical methods.
