 ** non-SMP systems : disable symmetric multi-processing support
 ** choose the most suitable processor family for your machine. 
 e.g.  Processor family -> Pentium-III / Celeron(Coppermine) / Pentium-III Xeon
 ** if you have a dual cores CPU or SMP system, don't choose a processor family which
has no TSC (time stamp counter). 
Don't choose 586/K5/5x86/6x86/6x86MX if you have a dual cores CPU.
