1.10 Switches and jumpers
The motherboard frequency is adjusted through the DIP switches. The white block
represents the switch position. The illustration below shows the ON and OFF
positions of the switches.

Make sure that the J6 jumper is set to pins 2-3 ( jumper mode) before setting
the above switches.
The option to set the CPU core:bus frequency multiple is available only on
unlocked CPUs. If you are using a locked CPU, setting the switches does not
produce any effect.
1. CPU external frequency selection (SW1 Switches 1-5)
This option tells the clock generator what frequency to send the CPU. This
allows the selection of the CPU’s external frequency (or Bus Clock). The BUS
Clock multiplied by the Frequency Multiple equals the CPU’s internal frequency
(the advertised CPU speed).
To select the CPU external frequency using the DIP switches, ensure that the
J6 jumper is set to jumper mode.
Set the CPU frequency only to the recommended settings. Frequencies other
than the recommended CPU bus frequencies are not guaranteed to be stable.
