  We report on our ongoing project of determining the chiral condensate of
two-flavor QCD from the Banks-Casher relation. We compute the mode number of
the O(a)-improved Wilson-Dirac operator for several values of \Lambda, and we
discuss different fitting strategies to extract the chiral condensate from its
mass and \Lambda dependence. Our preliminary results haven been obtained at two
different lattice spacings by using CLS-configurations.
