Jumper Setting
Jumper pin headers show on right side are
used to configure system clock, CPU
multiplier and CPU voltages.
System Clock - JP11, JP12 and JP13
JP11, JP12 and JP13 are 3-pins header
jumper which is used to adjust System
Clock from 50MHz to 83 MHz.
CPU Multiplier - JP4, JP5 and JP6
JP4, JP5 and JP6 are 2-pins header jumper
hich is used to adjust CPU core multiplier
from 1.5X to 5.5X.
CPU Voltages - JP33
JP33 is used to adjust onboard voltages output from Switching type regulators to CPU by
inserting or removing mini jumper from pin headers.
Those hardware settings are made through the use of jumper caps to connect jumper pins on
the main board. The jumpers will be show graphically such as to connect pins 3&4 and
5&6, and to connect pins 1&2 and 3&4 for six pin jumpers.
Jumpers will be show graphically such as to connect pins 2&4 and to connect
pins 3&4 for four pin jumpers.
Jumpers with two pins will be shown as for Short (On) and for Open (Off).
To connect the pins, simply place a plastic jumper cap over the two pins as diagramed.
