Jumper Settings
Jumpers
Several hardware setting are made through the use of jumper caps to
connect jumper pins (Jxx) on the mainboard. See " Map of the
mainboard" for locations of jumpers.
The jumper settings will be described numerically such as [----], [12], [2-3] for no connection, connect pins 1 & 2, and connect pins 2
& 3 respectively. Pin 1 for our mainboard is always on top one or
on the left when holding the mainboard with the keyboard away from
yourself. "P1" is written besides pin 1 on jumper with three pins.
The jumpers will also be shown graphically such as to connect
pin 1&2 and to connect 2&3. Jumpers with two pins will be
shown as for Short (on )and for Open (off).For manufacturing simplicity it may be sharing pins from other groups. Use the
diagrams in this manual instead of following the pin layout on the
board. Settings with two jumper numbers require that both jumpers
be moved together. To connect the pin, simply place a plastic jumper
cap over the two pins as diagrammed.

CPU Installation
The motherboard provides a ZIF socket 370. The CPU that came
with the motherboard should have a fan attached to it to prevent
overheating . If this is not the case then purchase a fan before you
turn on your system.
To install a CPU , first turn off your system and remove its cover.
Locate the ZIF socket and open it by first pulling the lever sideways
away from the socket then upwards to a 90-degree right angle. Insert the CPU with the correct orientation shown . The notched corner should point towards the end of the lever. Because the CPU has
a corner pin for two of the four corners, the CPU will only fit in the
orientation as shown.

Selecting the CPU Frequency
CPU voltage auto-detection and allow user to set CPU frequency
through BIOS setup, no jumper or switch is needed. The correct
CPU information is saved into EPROM, with these technologies,
the disadvantages of Pentium base jumper-less design are eliminated.
There will be no worry of wrong CPU voltage detection and no need
to re-open the housing if CMOS battery loss. The CPU frequency
selection is set by going into:
Choose “CPU SPEED SETTING” from the Main Menu and a screen
with a list of items appears.
CPU Speed
Set to Manual user can use the next two items to decide the
CPU speed.
CPU Ratio
This item lets you select the ratio of Core/Bus frequency. Have
the following selection: 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7.
0x, 7.5x,8
CPU Freqency
This item lets you set external clock (bus clock). The possible
settings are 66,100 and 133 MHZ....
Clearance Requirements
To maintain proper airflow once the processor is installed on the
mainboard, the processor and fan heatsink require certain space
clearances. The clearance above the processor must be at least 0.3
inches. The clearance on at least 3 of 4 sides of the processor and
fan heatsink must be at least 0.2 inches. All cables (for Floppy drive,
Hard drive,CD-ROM,and so on) must be routed clear of the processor and its airspace.
Fan Exhaust
The processor must be kept cool by using a processor with heatsink
and fan attached . The temperature of the air filled with the fan/
heatsink cannot exceed 45 OC(113 OF ) . The ambient or room temperature must be below 37 OC ( 99 OF) .

a. IDE activity LED (HD-LED)
This connector supplies power to the cabinet’s IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors will cause the LED to light up.
b. Power LED Lead (PW_LED)
The system power LED lights when the system’s power is on.
c.SMI Suspend Switch Lead (SMI)
This allows the user to manually place the system into a suspend
mode or “Green” mode where systematic activity will be instantly decreased to save electricity and expand the life of certain components when the system is not in use. This 2-pin connector (see the figure below) connects to the case-mounted suspend switch. If you do not have a switch for the connector, you
may use the “Turbo Switch” since it does not have a function.
SMI is activated when it detects a short to open moment and
therefore leaving it shorted will not cause any problems. It may
require one or two pushes depending on the position of the
switch. Wake-up can be controlled by settings in the BIOS but
the keyboard will always allow wake-up (the SMI lead cannot
wake-up the system). If you want to use this connector,"Suspend
Switch" in the Power Management Setup of the BIOS SOFTWARE section should be on the default setting of Enable
d. Reset Switch Lead (RST)
This 2-pin connector connects to the case-mounted reset switch
for rebooting your computer without having to turn off your
power switch. This is a preferred method of rebooting in order
to prolong the life of the system's power supply.
