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].

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.

3-20MS-7176 ATX MainboardCell Menu 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.
