My experience with Dual Pentium boards so far has been that dual-MMX will
always be a problem...
MMX processors use a lot of power, and most of the dual boards can't take
that.. you should also see to it that you have a power supply in your
computer which is capable of supplying enough power to all the components
you use (which was one of the problems which I stumbled upon)
