Connectors
==========
JP1 External Battery connector is used for the external battery.
This is use when internal battery is not conected.
JP27 Turbo switch connector will be connected to the turbo switch
of your computer case. This is used to toggle the system
speed between fast and slow processing speed.
JP26 Reset switch connector will be connected to the reset switch 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 OFF position.
JP28 Turbo LED connector will be connected to the turbo LED of
your computer case. The LED will light up when the systen is
running in high processing speed. (Note the positive and nega-
tive of the LED)
JP29 Keylock and Power LED connector will be connected to your
computer case. Keylock is used to lock the keyboard. Power
LED will light up when you turn on your power supply.
JP30 Speaker connector will be connected to the speaker of your
computer case.
P1,P2 Power Supply connector is connected from the output of the
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.
J1 Keyboard connector. This is used for inputting signal from
the keyboard.
Memory Configuration
====================
The system board Memory can be expanded from IMB to 64MB.Mem-
ory can be installed by using 256K, 1M, 4M and 16M SIMM RAM
Module.

MEMORY SIZE BANK O BANK 1
1M 256K
2M 256K 256K
4M 1M
8M 1M 1M
16M 4M
32M 4M 4M
64M 16M
128M 16M 16M
5M 256K/1M 1M/256K
20M 1M/4M 4M/1M
AMI BIOS SETUP
================
AMI BIOS support 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 AMI 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 "AUTO CONFIGURATION WITH BIOS DEFAULTS"
for setup.
