As a 'general rule' if you divide the CPU speed (200) by an integer like
2 or 3, and it results in one of your available bus speeds, then that's
prolly the bus speed you will use. So 200/3 = 66.67, or ~66. So you
would use the 66 bus speed with a multiplier of 3.0 for your 200 mhz
cpu. It's a function of 'pairing' the available bus speeds with the
available multipliers on the mother board to achieve the CPU rate.
Usually it's best to start with the highest bus speed available, then
look at the multipliers available. If the cpu has it's own built-in
multiplier, then there is less flexibility. This is all from my limited
experience. Someone that has more of that could doubtless give you a
more refined explanation.  {^;  Good Modeming!  /\oo/\
