We show how an extremal Reissner-Nordstrom black hole can be obtained
by wrapping a dyonic D3-brane on a Calabi-Yau manifold. In the orbifol
d limit T-6/Z(3), We explicitly show the correspondence between the so
lution of the supergravity equations of motion and the D-brane boundar
y state description of such a black hole. (C) 1998 Elsevier Science B.
