ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
„
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
„
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
„
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

2.4.19 PCI-Express Mini Card Socket: CNS1 (Optional)
CNS1 is a PCI Express Mini Card socket, support both a x1 PCI
Express link and a USB 2.0 link. A PCI Express Mini Card can use
either PCI Express or USB 2.0 (or both). USB 2.0 support will help
during the transition to PCI Express, because peripheral vendors will
need time to design PCI Express into their chip sets. During the
transition, PCI Express Mini Cards can be quickly implemented using
USB 2.0.
This connector is optional. It is not mounted by default design.

Award BIOS Utility
The Phoenix-Award BIOS provides users with a built-in Setup program
to modify basic system configuration. All configured parameters are
stored in a battery-backed-up RAM (CMOS RAM) to save the Setup
information whenever the power is turned off.
4.1
Entering Setup
There are two ways to enter the Setup program. You may either turn
ON the computer and press <Del> immediately, or press the <Del>
and/or <Ctrl>, <Alt>, and <Esc> keys simultaneously when the
following message appears at the bottom of the screen during POST
(Power on Self Test).
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still want to
enter Setup, please restart the system to try it again. Turning the
system power OFF and ON, pressing the “RESET” button on the
system case or simultaneously pressing <Ctrl>, <Alt>, and <Del> keys
can restart the system. If you do not press keys at the right time and
the system doesn’t boot, an error message will pop out to prompt you
the following information:
PRESS <F1> TO CONTINUE, <CTRL-ALT-ESC> OR <DEL> TO ENTER SETUP

ACPI Suspend Type
This item specifies the power saving modes for ACPI function. If
your operating system supports ACPI, such as Windows 98SE,

[S1(POS)] The S1 sleep mode is a low power state. In this state,
no system context is lost (CPU or chipset) and hardware maintains
all system context.
[S3(STR)] The S3 sleep mode is a lower power state where
the information of system configuration and open
applications/files is saved to main memory that remains
powered while most other hardware components turn off to save
energy. The information stored in memory will be used to restore
the system when a “wake up” event occurs.

also allows the user to define which type of soft power OFF
sequence the system will follow. The default value is “Instant-Off”.

This option follows the conventional manner systems
perform when power is turned OFF. Instant-Off is a soft
power OFF sequence requiring only the switching of the
power supply button to OFF
Upon turning OFF system from the power switch, this
option will delay the complete system power OFF
sequence by approximately 4 seconds. Within this delay
period, system will temporarily enter into Suspend Mode
enabling you to restart the system at once.
Wake-Up by PCI card
If enable this item, the system can automatically resume when the
PCI Modem or PCI LAN card receives an incoming call.
Power On by Ring
This option allows the system to resume or wake up upon detecting
any ring signals coming from an installed modem. The default value
is “Enabled”.
Resume by Alarm
If enable this item, the system can automatically resume after a
fixed time in accordance with the system’s RTC (realtime clock).

Resources Controlled By
The Award Plug and Play BIOS can automatically configure all
boot and Plug and Play-compatible devices. If you select Auto, all
interrupt request (IRQ), DMA assignment, and Used DMA fields
disappear, as the BIOS automatically assigns them. The default
value is “Manual”.
IRQ Resources
When resources are controlled manually, assign each system
interrupt to one of the following types in accordance with the type
of devices using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus

When you select this function, the following message will appear at the
center of the screen to assist you in creating a password.
ENTER PASSWORD
Type a maximum eight-character password, and press <Enter>. This
typed password will clear previously entered password from the CMOS
memory. You will be asked to confirm this password. Type this
password again and press <Enter>. You may also press <Esc> to
abort this selection and not enter a password.
To disable the password, just press <Enter> when you are prompted to
enter a password. A message will confirm the password is getting
disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.
PASSWORD DISABLED
When a password is enabled, you have to type it every time you enter
the Setup. It prevents any unauthorized persons from changing your
system configuration.
Additionally, when a password is enabled, you can also require the
BIOS to request a password every time the system reboots. This would
prevent unauthorized use of your computer.
You decide when the password is required for the BIOS Features
Setup Menu and its Security option. If the Security option is set to
“System”, the password is required during booting up and entry into the
Setup; if it is set as “Setup”, a prompt will only appear before entering
