2. CPU Core:Bus frequency multiple (SWITCH 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.
