6. CPU External (BUS) Frequency Selection (FS0, 1, 2) (Baseboard)
These jumpers tells the clock generator what frequency to send to the CPU.
These allow the selection of the CPU’ s External frequency (or BUS Clock). The
BUS Clock multiplied by the BUS Ratio equals the CPU’s Internal frequency
(the advertised CPU speed).
