JUMPER SWITCHES
===============
These switches consist of two or three pins set in a plastic base. Two of
the pins are covered by a cap which connect or short each other. It is
possible to change the switch setting by moving the cap between the first or
last two pins.
JUMPERS OPEN & SHORT
====================
If you wish to change any of the jumper setting, make sure the board is
disconnected from the power source. This is to protect the mother board from
getting damage.
MODEL1 JP1 (MODEL2 JP2) Reset / Charge CMOS
===========================================

CMOS Reset/Charge is used to reset and charge CMOS.If you reset
the CMOS all datas in the CMOS will be erase.To reset CMOS,
place a jumper cap in pin 1 & 2 then turn on the power supply for
1 to 2 seconds then turn off the power supply. In this procedure the
CMOS is reset, all the datas in the CMOS is erase. Place the jumpe
cap in pin 2 & 3 for CMOS charge,then run setup.
JP1 (JP2) 1-2 Reset CMOS
JP1 (JP2) 2-3 Charge CMOS
MODELI JP2 (MODEL2 JP1) Mono / Color Monitor selector
=====================================================
Mono / Color Monitor selector is used to select the type of video
display you are using. The choice is between CGA and MONO. CGA
is only for CGA display. MONO is for all other display including
EGA, VGA and MONO. The default is MONO.
JP2 (JP1) OPEN MONO

MODEL1 JP8, JP9 (MODEL2 JP7,JP8) Clock Generator Frequency Selector
===================================================================
Clock Generator Frequency selector is used to select diferent frequen-
cy of the clock generator. The frequency is depend of the MHz of
the CPU you are using.
FREQUENCY JP8 (JP7) JP9 (JP8)
50 MHz CLOSE OPEN
66 MHz OPEN CLOSE
80 MHz OPEN OPEN
JP10 Enable/Disable PQFP CPU (MODEL1 only)
==========================================
If you mount a 80386 PQFP CPU in your main board, this function is
used to disable the 80386 PQFP CPU with out pulling out from the
main board. If you are not using the 80386 PQFP CPU leave this
jumper JP10 OPEN.

JP10 OPEN ENABLE 80386 PQFP CPU
JP10 CLOSE DISABLE 80386 PQFP CPU
Connectors
==========
The mother board have eight connectors.Six of them resemble jumper
switch without caps. The seventh is a large double connector for the
power supply and the last is for the keyboard connector.

J1 External Battery connector is used for the external battery.
(J1) This is used when internal battery is not connected.
JP12 Turbo switch connector will be connected to the turbo switch
(JP4) of YOU' Compoter case. This is used to toggle the system
speed between fast and slow processing speed.
S1 Reset switch connector will be connected to tile reset switch
(S1) of your computer case. Resetting the system, it will restart
the computer from self-test without turning off the power
supply.This connection is always in OFl; position.
JP13 Turbo LED connector will be connected to the turbo LED of
(JP3) your computer case. The LED will light up when the system
is running in high processing speed. (Note the positive and
negative of the LED )
J19 Keylock and Power LED connector will be connected to your
(J16) computer case. Keylock is used to lock the keyboard. Power
LED will light up when you turn on your power supply.
JP11 Speaker connector will be connected to the speaker of your
(JP6) computer case.
J3-J4 Power Supply connector is connected from the output of the
(J9,J10) power supply.Most of the power supply has two connectors
which will be connected to the main board. Each connector

has six wires, two of the wires are black. To connect to the
main board, make sure that the black wires is in the middle.
Wrong connection will cause damage of the main board.
J2 Keyboard connector. This is used for inputting signal from
(J2) the keyboard.
Memory Configuration
====================
The system board Memory can be expanded from 1MB to 32MB.
Memory can be installed by using 256K, 1M and 4M SIMM RAM
Module.
MEMORY SIZE BANK O BANK 1
1M 256K
2M 256K 256K
4M 1M
8M 1M 1M
16M 4M
32M 4M 4M
Installing Memory Modules
=========================
Ther are four sockets of 72 pins on the system board that can accommodate
up to a maximum of 128 megabytes of memory.There are 2 bank of SIMM modules
socket for use with 256K, 512K, 1M, 2M, 4M and 8M size RAM Modules with the
access time of 70ns or faster. Extreme use of caution should be exercise
when installing or removing the SIMM memory module in order to avoid
damaging the SIMM socket.
Steps for installing SIMM RAM Modules in the system board.
(1). (2). (3).
Insert the SIMM Press it forward The installed
at an angle into into the retaining SIMM should be
the socket's edge clips at 90 degree to
connector slot the board
1 Carefully hold the SIMM. Insert the SIMM module's "GOLD EDGE" connector
into the socket at a 70 degree angle and guide the component side of the
module. (Note that the modules can only be fit into the socket one way.)
2 Gently press the SIMM module into the socket in downward position, then
snap it into place in the vertical position. The module should clip into
the locking tabs at each end of the socket. The SIMM is probably not
inserted fully into the socket if the pegs do not fit into the hole.
3 To remove the module, gently push the edge of the sockets. Disengage one

side of the modules first, then the other side, to avoid breaking the
socket.
AWARD BIOS SETUP
================
Award BIOS support plug and play function and has a built-in setup program
that allows the users to modify the basic system configuration. This type of
information is stored in CMOS so that it retains the setup information when
the power is turned off.
1. Turn on or reboot the system. when the below message appears at the
bottom of the screen during the POST ( Power On Self Test ) press
DEL
key to enter setup.
2. Press the DEL key to enter the Award BIOS program and the main menu
will appear on the screen. The main menu allows you to select from
ten
setup functions and two exit choices.
3. For the safe, please select "LOAD SETUP DEFAULTS" for BIOS setup.
