(G) JP100: FSB Clock Selection
JP100 is designed on the board for some special purpose. You can use the
setting on JP100 to force the FSB clock at 66/100MHz despite of the CPU type.
(When select 1-2 setting, the system board will detect the FSB clock automatically.)
(When select 2-3 setting, the FSB clock will be always 66MHz despite of CPU type.)
(When no jumper on JP100, FSB clock will be always 100MHz despite of CPU type)
