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).
