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
Page 3
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.

Charge/Discharge CMOS (JP1)
=====================
CMOS Charge/Discharge CMOS is used to Charge and Discharge CMOS. If you
discharge the CMOS all datas in the CMOS will be erase. To discharge 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
discharge, all the datas in the CMOS is erase.Place the jumper cap in pin
2 & 3 for CMOS charge, then run setup.

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.
