Well, what about asking SPSS what it does, at first? What assumptions have you had re. the covariance matrix?
I guess the default will be a linear discriminant analysis, but I do not know SPSS. And *you* should know whether the analysis you did with SPSS made sense or not for your data (hence also which models/methods you applied).
