Abstract
We present non-supersymmetric toroidal compactifications of
type-I string theory with both constant background NSNS two-form flux
and non-trivial magnetic flux on the various D9-branes. The
non-vanishing B-flux admits four-dimensional models with three
generations of chiral fermions in standard model like gauge groups.
Additionally, we consider the orbifold 
4/
2,
again with both kinds of background flux present, leading to
non-supersymmetric as well as supersymmetric models in six dimensions.
All models have T-dual descriptions as intersecting brane worlds.
