Press  to enter the sub-menu and the following screen appears: 
						

							4-24 Chapter 4
Onboard Serial Port A/B
These items specify the base I/O port addresses of the onboard Serial
Port A/B.  Selecting [Auto] allows BIOS to automatically determine the
correct base I/O port address. Settings: [Auto], [3F8/COM1], [2F8/COM2],
[3E8/COM3], [2E8/COM4] and [Disabled].
Serial Port B Mode
This setting allows you to specify the operation mode for Serial Port B.

[Normal]RS-232C Serial Port
[IrDA]IrDA-compliant Serial Infrared Port
[ASKIR]Amplitude Shift Keyed Infrared Port
IR Duplex Mode
This setting controls the operating mode of IR transmission/reception.
Setting options: [Full-Duplex], [Half-Duplex]. Under [Full-Duplex] mode,
synchronous, bi-directional transmission/reception is allowed. Under
[Half-Duplex] mode, only asynchronous, bi-directional transmission/
reception is allowed.
IR Receiver/Xmitter Polarity
This setting controls the data transfer speed of IR transmission/reception.
Setting options: [High], [Low].
Onboard Parallel Port
This field specifies the base I/O port address of the onboard parallel port.
Selecting [Auto] allows BIOS to automatically determine the correct base
I/O port address. Settings: [Auto], [378], [278], [3BC] and [Disabled].
Parallel Port Mode
This item selects the operation mode for the onboard parallel port: [ECP],
[Normal], [Bi-Dir] or [EPP].
EPP Version
The item selects the EPP version used by the parallel port if the port
is set to [EPP] mode. Settings: [1.7] and [1.9]. 
						

							4-25BIOS Setup
Parallel Port IRQ
When Onboard Parallel Port is set to [Auto], the item shows [Auto]
indicating that BIOS determines the IRQ for the parallel port
automatically.
Parallel Port DMA Channel
This feature needs to be configured only when Parallel Port Mode is
set to the [ECP] mode. When Parallel Port is set to [Auto], the field
will show [Auto] indicating that BIOS automatically determines the
DMA channel for the parallel port. 
						

							4-26 Chapter 4
This section shows the status of your CPU, fan, overall system status,
etc.  Monitor function is available only if there is hardware monitoring mecha-
nism onboard.
Chassis Intrusion
The field enables or disables the feature of recording the chassis intrusion
status and issuing a warning message if the chassis is once opened.  To clear
the warning message, set the field to Reset.  The setting of the field will
automatically return to Enabled later.  Settings: Enabled, Reset, Disabled.
Smart Fan Control Function
This field enables or disables smart fan control function.  If you choose “enable”,
CPU fan and system fan speed will depend on CPU temperature.  When CPU
temperature is high, the fan will spin quickly.  This function will reduce the
noise produced by fan.  If you disable it, the CPU fan and system fan will spin in
full speed.  We recommend users to enable this function.
CPU/System Temperature, CPU/System Fan Speed, +2.5V, Vcore, +3.3V,
+5.0V, Chipset vtt, +1.5V
These items display the current status of the monitored hardware devices/
components. 4.9 PC Health Status 
						

							4-27BIOS Setup
Use this menu to specify your settings for frequency/voltage control.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
DRAM  Frequency
Use this field to configure the clock frequency of the installed DRAM. Settings
are:
PSB 400:  [266], [Auto].
PSB 533:  [266], [333], [Auto].
PSB 800:  [266], [333], [400], [Auto].
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference).  The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves.  If you do not have any EMI
problem, leave the setting at [Disabled] for optimal system stability and
performance.  But if you are plagued by EMI, setting to [Enabled] for EMI 4.10 Frequency/Voltage Control

reduction.  Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clockspeed
which may just cause your overclocked processor to lock up.
CPU FSB Clock (MHz)
This item shows the CPU FSB(Front Side Bus) information. It doesn’t allow
you to make any setting.
DDR Clock (MHz)
This item shows the DDR clock speed. It doesn’t allow you to make any setting. 
						

							4-29BIOS Setup
When you select this function, a message as below will appear on the
screen:
Type the password, up to six characters in length, and press .
The password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press . You may also press  to abort the selection and not
enter a password.
To clear a set password, just press  when you are prompted to
enter the password. A message will show up confirming the password will be
disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.
When a password has been set, you will be prompted to enter  it every
time you try to enter Setup. This prevents an unauthorized person from changing
any part of your system configuration.
Additionally, when a password is enabled, you can also have AMIBIOS
to request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the password
prompt is required is the PASSWORD CHECK option of the ADVANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to [Always], the
password is required both at boot and at entry to [Setup]. If set to [Setup],
password prompt only occurs when you try to enter Setup. 4.11 Set Supervisor/User PasswordAbout Supervisor Password & User Password:
Supervisor password:Can enter and change the
settings of the setup menu.
User password:Can only enter but do not have
the right to change the settings of
the setup menu. 
						

							4-30 Chapter 4
The two options on the main menu allow users to restore all of the BIOS
settings to Optimal defaults or Fail Safe defaults.  The Optimal Defaults are the
default values set by the mainboard manufacturer for the best system perform-
ance but probably will cause a stability issue.  The Fail Safe Defaults are the
default values set by the mainboard manufacturer for stable performance of the
mainboard.
When you select Load Optimal Defaults, a message as below appears:
Pressing [Enter] loads the default values that are factory settings for stable
system performance.
When you select Fail Safe Defaults, a message as below appears:
Pressing [Enter] loads the default BIOS values that enable the best system
performance but may lead to a stability issue. 4.12 Set Optimal/Fail Safe Defaults

Using 4- or 6-Channel
Audio Function
The motherboard is equipped with Realtek ALC655 chip,
which provides support for  6-channel audio output, including 2
Front, 2 Rear, 1 Center and 1 Subwoofer channel.  ALC655 allows
the board to attach 4 or 6 speakers for better surround sound
effect.  The section will tell you how to install and use 4-/6-channel
audio function on the board. 
						

							5-2 Chapter 5
You need to install the driver for Realtek ALC655 chip to function properly
before you can get access to 4-/6-channel audio operations.  Follow the proce-
dures described below to install the drivers for different operating systems.
Installation for Windows 98SE/ME/2000/XP
For Windows®
 2000, you must install Windows®
 2000 Service Pack2 or
later before installing the driver.
The following illustrations are based on Windows®
 XP environment and
could look slightly different if you install the drivers in different operating
systems.
1.Insert the companion CD into the CD-ROM drive.  The setup screen will
automatically appear.
