Consistent embeddings are found of the minimal N = 2 and N = 3 gauged supergravities in four dimensions into its maximally supersymmetric, N = 8, counterpart with a dyonic ISO(7) gauging. These minimal truncations retain the metric along with relevant U(l) and S0(3) R-symmetry gauge fields selected from the ISO (7) ones. The remaining ISO (7) gauge fields are turned off, with subtleties introduced by the dyonic gauging, and the scalars are fixed to their expectation values at the N = 2 and N = 3 vacua of theN = 8 theory. Using the truncation formulae for massive type I IA supergravity on the six-sphere to D = 4 N = 8 ISO (7) supergravity, the minimal D = 4 N = 2 and N = 3 gauged supergravities are then uplifted consistently to ten dimensions.
