							3-14MS-7176 ATX MainboardPower Management FeaturesMSI Reminds You...
S3-related functions described in this section are available only
when your BIOS supports S3 sleep mode.
ACPI Aware O/S
This item is to activate the ACPI (Advanced Configuration and Power Management
Interface) Function. If your operating system is ACPI-aware, such as Windows 98SE/
2000/ME/XP, select [Enabled]. Settings: [Enabled] and [Disabled].
Suspend mode
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 98SE, Windows ME and Windows 2000,
you can choose to enter the Standby mode in S1 (POS) or S3 (STR) fashion through
the setting of this field. Options are:
[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 sys-
tem 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. 
						

							3-15 BIOS SetupSuspend Time Out (Minute)
If system activity is not detected for the length of time specified in this field, all
devices except CPU will be shut off. Settings: [Disabled], [1min], [2min], [4min], [8min],
[10min], [20min], [30min], [40min], [50min], [60min].
Power Button Mode
This feature allows users to configure the Power Button function. Settings are:
[On/ Off]The power button functions as a normal power-on/-off
button.
[Suspend]When 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.
Restore on AC Power Loss
This setting specifies whether your system will reboot after a power failure or
interrupt occurs. Available settings are:
[Power Off]Leaves the computer in the power off state.
[Power On]Leaves the computer in the power on state.
[Last State]Restores the system to the previous status before power
failure or interrupt occurred.
Wakeup Event Setup
Press  to enter sub-menu and the following screen appears.
USB Device Wake-Up from S3
This setting allows USB device wake up the system from S3 state. Settings are:
[Enable], [Disabled].
Keyboard Wakeup
The item specifies how the system will be awakened from power saving mode
when input signal of the keyboard is detected. Setting options: [Disabled], [Specific
Key], [Any Key].
Specific Key for PowerOn
This controls how and whether the keyboard is able to power on the system.
Press Enter, and then you must press a key for power on the system.
Mouse WakeUp
This setting determines whether the system will be awakened from what power
saving modes when input signal of the mouse is detected. Setting options: [Disabled],
[Enabled]. 
						

							3-16MS-7176 ATX Mainboard
Resume On PCI PME#
When setting to [Enabled], this setting allows your system to be awakened from
the power saving modes through any event on PME (Power Management Event).
Setting options: [Disabled], [Enabled].
Resume On RTC Alarm
This is used to enable or disable the feature of booting up the system on a
scheduled time/date from the S3, S4, and S5 state. Setting options: [Disabled],
[Enabled]. 
						

							3-17 BIOS SetupPCI/PNP Resource Management
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 NVRAM
The NVRAM (Non-volatile Random Access Memory) is where the BIOS stores re-
source information for both PNP and non-PNP devices in a bit string format. When the
item is set to [Yes], the system will reset NVRAM right after the system is booted up
and then set the setting of the item back to [No] automatically.
Plug & Play O/S
When set to Yes, BIOS will only initialize the PnP cards used for booting (VGA, IDE,
SCSI). The rest of the cards will be initialized by the PnP operating system like
Windows 98, 2000, ME or XP. When set to No, BIOS will initialize all the PnP cards.
Select Yes if the operating system is Plug & Play.
PCI Latency Timer
This item controls how long each PCI device can hold the bus before another takes
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values. Setting options: [32], [64], [96], [128], [160],
[192], [224], [248].
PCI Slot1~4 IRQ Preference
These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9],
[10], [11], [12], [14], [15], [Auto]. Selecting [Auto] allows BIOS to automatically deter-
mine the IRQ line for each PCI slot. 
						

							3-18MS-7176 ATX Mainboard
IRQ 3/4/5/7/9/10/11/14/15
These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool of available
IRQs passed to devices that are configurable by the system BIOS. The available IRQ
pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from
the IRQ pool, the end user can use these settings to reserve the IRQ by assigning an
[Reserved] setting to it. Onboard I/O is configured by AMIBIOS. All IRQs used by
onboard I/O are configured as [Available]. If all IRQs are set to [Reserved], and IRQ
14/15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI and PnP
devices. Available settings: [Reserved] and [Available].
DMA Channel  0/1/3/5/6/7
These items specify the bus that the system DMA (Direct Memory Access) channel is
using.
The settings determine if BIOS should remove a DMA from the available DMAs passed
to devices that are configurable by the system BIOS. The available DMA pool is
determined by reading the NVRAM. If more DMAs must be removed from the pool, the
end user can reserve the DMA. 
						

							3-19 BIOS SetupH/W Monitor
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.
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. Setting options:  [Disabled], [Enabled], [Reset].
Smart Fan Target
The mainboard provides the Smart Fan system which can control the fan speed
automatically depending on the current temperature to keep it with in a specific range.
Smart Fan Tolerance
You can select a fan tolerance value here for the specific range for the “Smart  Fan
Target Temp. (o
C)” item. If the current temperature of the fan reaches to the maximum
threshold (the temperatures set in the “Smart  Fan Target Temp. (o
C)” plus the toler-
ance values you set here), the fan will speed up for cooling down. On the contrary,
if the current  temperature reaches to the minimum threshold (the set temperatures
minus the tolerance value), the fan will slow down to keep the temperature stable.
System/CPU Temperature, CPU FAN Speed, Vcore, +12V, VCC5, +3VSB,
VBAT
These items display the current status of all of the monitored hardware devices/
components such as CPU voltages, temperatures and all fans’ speeds.

Adjust DDR Voltage (V)
Adjusting the DDR voltage can increase the DDR speed.  Any changes made to this
setting may cause a stability issue, so changing the DDR voltage for long-term
purpose is NOT recommended.
Adjust NB Voltage (V)
NorthBridge voltage is adjustable in the field, allowing you to increase the perfor-
mance of your NorthBridge when overclocking, but stability may be affected.
CPU Over Voltage (mV)
The settings are used to adjust the CPU clock multiplier (ratio) and CPU core voltage
(Vcore). These settings offer users a tool to overclock the system. The items here includes some important settings of CPU and PCI functions.MSI Reminds You...
Change these settings only if you are familiar with the chipset.MSI Reminds You...
The settings shown in different color in CPU Voltage, DDR Voltage and
NB Voltage help to verify if your setting is proper for your system.
Gray:Default setting.
White:Safe setting.
Yellow:High performance setting.
Red:Not recommended setting and the system may be
unstable.
Changing CPU Voltage, DDR Voltage and NB Voltage may result in the
instability of the system; therefore, it is NOT recommended to change
the default setting for long-term usage.
