2. CPU Core:Bus frequency multiple (DSW2 Switches 1-4)
This option sets the frequency multiple between the CPU internal and
external frequencies. This must be set in conjunction with the CPU Bus
Frequency.
Make sure that the JEN jumper is set to 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.

3. CPU external frequency selection (DSW1 Switches 1-6)
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 JEN jumper is set to jumper mode.
