The CPU speed is controlled by setting the bus speed and the multiplier with
the jumpers described above that are appropriate for your CPU and memory.
You must have a 100MHz processor AND PC/100 memory to run at a bus
speed of 100MHz. Tyan does not recommend and is not responsible for
functionality or damage to components caused by operating a CPU, memory or
important!
any bus at higher than rated speeds (overclocking).

JP11 is used to set CPU I/O voltage. Most newer
CPUs have 3.3V I/O voltage and a lower core
voltage, so this jumper should be off. For certain
older CPUs the Core voltage is the same as the I/
O voltage so this jumper should be closed (on).
Check the specs on your CPU before you set this
jumper.
