SuspendWhen you press the power button, the computer enters the
suspend/sleep mode, but if the button is pressed for more than
four seconds, the computer is turned off.
Run VGABIOS if S3 Resume
When ACPI Suspend Mode is set to S3 or S1&S3, users can select the options in this
field.  Selecting [Yes] allows BIOS to call VGABIOS to initialize the VGA card when
system wakes up (resumes) from S3 sleep state.  The system resume time is short-
ened when you disable the function, but system will need an AGP driver to initialize
the VGA card.  Therefore, if the AGP driver of the card does not support the initializa-
tion feature, the display may work abnormally or not function after resuming form S3.
Options: Auto, Yes, No.
After AC Power Lost
This setting specifies whether your system will reboot after a power failure or
interrupt occurs. Available settings are:
Power OffLeaves the computer in the power off state.
Power OnLeaves the computer in the power on state.

MSI Reminds You...
IRQ (Interrupt Request) lines are system resources allocated to I/O
devices. When an I/O device needs to gain attention of the operating
system, it signals this by causing an IRQ to occur. After receiving the
signal, when the operating system is ready, the system will interrupt
itself and perform the service required by the I/O device. 
						

							3-21 BIOS Setup
PNP/PCI Configurations
This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with
its special components.  This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the
default settings.
Clear ESCD
Normally, you leave this field Disabled. Select Enabled to reset Extended System
Configuration Data (ESCD) when you exit Setup if you have installed a new add-on
and the system reconfiguration has caused such a serious conflict that the operating
system can not boot. The settings are: Enabled and Disabled.
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all of the
boot and Plug and Play compatible devices. However, this capability means abso-
lutely nothing unless you are using a Plug and Play operating system such as Win-
dows
® 95/98. If you set this field to “manual” choose specific resources by going into
each of the sub menu that follows this field (a sub menu is preceded by a “Ř”). The
settings are: Auto (ESCD), Manual.
IRQ Resources
The items are adjustable only when Resources Controlled By is set to Manual.
Press  and you will enter the sub-menu of the items. IRQ Resources list IRQ
3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending on the type of
device using the IRQ. Settings are:
PCI DeviceFor Plug & Play compatible devices designed for PCI bus
architecture.
ReservedThe IRQ will be reserved for further request.

PCI/VGA Palette Snoop
When set to Enabled, multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device. Bit 5 of the
command register in the PCI device configuration space is the VGA Palette Snoop bit
(0 is disabled).  For example, if there are two VGA devices in the computer (one PCI
and one ISA) and the:
The setting must be set to Enabled if any ISA bus adapter in the system requires VGA
palette snooping.
Assign IRQ for VGA/USB
The items allow you to assign an IRQ line to the VGA card and USB device separately.
Options: Enabled, Disabled.  VGA Palette Snoop
 Bit SettingAction
DisabledData read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
EnabledData read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s
palette registers, permitting the palette registers of both
VGA devices to be identical. 
						

							3-23 BIOS Setup
PC Health Status
This section shows the status of your CPU, fan, overall system status, etc.  Monitor
function is available only if there is hardware monitoring mechanism onboard.
CPU Warning Temperature
This item is used to specify a thermal limit for CPU. If CPU temperature reaches the
specified limit, the system will issue a warning which allows you to prevent the CPU
overheat problem. Settings: Disabled, 50
oC/122oF, 53oC/127oF, 56oC/133oF, 60oC/
140oF, 63oC/145oF, 66oC/151oF and 70oC/158oF.
System/CPU Temperature, System/CPU Fan Speed, Vcore, +3.3V, +5V, +12V,
-12V, -5V, VBAT(V), 5VSB(V)
These items display the current status of all of the monitored hardware devices/
components such as CPU voltages, temperatures and all fans’ speeds.
Shutdown Temperature
When the processor reaches the preset temperature, the ACPI-aware system will be
shut down. Settings: Disabled, 60
oC/140oF, 65oC/149oF, 70oC/158oF, 75oC/167oF.

Use this menu to specify your settings for frequency/voltage control.
Frequency/Voltage Control
Auto Detect DIMM/PCI Clk
This option allows you to enable/disable the feature of auto detecting the clock
frequency of the installed DIMM/PCI bus. The settings are: Enabled, Disabled.
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,
activate the Spread Spectrum for EMI reduction. Remember to disable Spread Spec-
trum 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.
Options: Disabled, +/-0.25%, +/-0.35%, +/-0.50%, +/-0.75%. 
						

							3-25 BIOS Setup
Load Fail-Safe/Optimized Defaults
The two options on the main menu allow users to restore all of the BIOS settings to
the default Fail-Safe or Optimized values. The Optimized Defaults are the default
values set by the mainboard manufacturer specifically for optimal performance of the
mainboard. The Fail-Safe Defaults are the default values set by the BIOS vendor for
stable system performance.
When you select Load Fail-Safe Defaults, a message as below appears:
Pressing Y loads the BIOS default values for the most stable, minimal system
performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing Y loads the default factory settings for optimal system performance.

When you select this function, a message as below will appear on the screen:
Type the password, up to eight characters in length, and press . The pass-
word 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 BIOS 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
Security Option of the Advanced BIOS Feature menu.  If the Security Option is set to
System, 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.
Set Supervisor/User Password

About 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.
