10 Processor Socket
11 Microprocessor Ratio (J101)
Example:
90 MHz processor and bus speed is 60 MHz
set the jumper to bus-to-core ratio to
60/90 = 2/3.
(bus-to-core ratio 1/2 = jumper conn.)
(bus-to-core ratio 2/3 = no jumper)
If the ratio is incorrect.. component
can OVER-HEAT and DAMAGE can occur !
