As stated I tried *ALL* of the FPU settings and received the same result or 
an "access violation", which I assumed meant my FPU did not support that 
feature set. I even tried to enable emulation, to see what the difference 
would be, but ppc386 said it was an invalid switch even though it lists it 
in the help output.
