3-16 Primary Graphic’s Adapter
This setting specifies which graphic card is your primary graphics adapter. 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. PCI Slot 1/2 IRQ
This setting specifies IRQ for PCI devices.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. 
						

							BIOS Setup
3-17Important
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 sig-
nals 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. IRQ Resource Setup
Press  to enter the sub-menu and the following screen appears. 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 avail-
able 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.

3-18 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. CPU Smart FAN Target
The mainboard provides the Smart Fan function which can control the CPU fan speed
automatically depending on the current temperature to keep it with in a specific range.
You can select a fan target value here. If the current CPU fan temperature reaches to
the target value, the smart fan function will be activated. It provides several sections
to speed up for cooling down automaticlly. PC Health Status CPU/ System Temperature, CPU FAN/ SYS FAN1/ SYS FAN2 Speed, CPU
Vcore, 3.3V, 5V, 12V, 5V SB
These items display the current status of all of the monitored hardware devices/
components such as CPU voltage, temperatures and all fans’ speeds.H/W Monitor 
						

							BIOS Setup
3-19 Current CPU Clock/ DRAM Frequency
These items show the current clocks of CPU and Memory frequency. Read-only. D.O.T. Control
This item allows users to select either/both of CPU and PCIE to be controlled under D.
O.T. The D.O.T. (Dynamic Overclocking Technology) is an automatic overclocking
function, included in the MSITM
’s newly developed Dual CoreCellTM 
Technology. It is
designed to detect the load balance of CPU and PCIE while running programs, and to
adjust the best frequency automatically. When the motherboard detects system is
running programs, it will speed up automatically to make the program run smoothly
and faster. When the system is temporarily suspending or staying in the low load
balance, it will restore the default settings instead. Usually the Dynamic Overclocking
Technology will be powered only when users PC need to run huge amount of data
like 3D games or the video process, and the CPU and PCIE frequency need to be
boosted up to enhance the overall performance.Cell MenuImportant
Change these settings only if you are familiar with the chipset.

3-20 AMD Cool’n’Quiet
The Cool’n’ Quiet technology can effectively and dynamically lower CPU speed and
power consumption. HT Ratio
This item allows you to set the Hyper Transport ratio. Adjust CPU FSB Frequency
This item allows you to set the CPU FSB frequency (in MHz). Adjust CPU Ratio
This item allows you to set the CPU ratio. Adjusted CPU Frequency
It shows the adjusted CPU frequency (FSB x Ratio). Read-only. Advance DRAM Configuration
Press  to enter the sub-menu and the following screen appears. DRAM Timing Mode
Setting to [Auto] enables DRAM CAS# Latency automatically to be determined by
BIOS based on the configurations on the SPD (Serial Presence Detect) EEPROM
on the DRAM module.Important
To ensure that Cool’n’Quiet function is ac-
tivated and will be working properly, it is
required to double confirm that:
1.Run BIOS Setup, and select Cell Menu.
Under Cell Menu, find AMD
Cool’n’Quiet, and set this item to
“Enable.”
2.Enter Windows, and select [Start]->
[Settings]->[Control Pannel]->[Power
Options]. Enter Power Options Prop-
erties tag, and select Minimal Power
Management under Power schemes.

3-21 FSB/Memory Ratio
This item will allow you to adjust the FSB/Ratio of the memory. Adjusted DDR Memory Frequency
It shows the adjusted DDR Memory frequency. Read-only. Adjust PCIE Frequency
This item allows you to set the PCI Express frequency (in MHz). Auto Disable DIMM/PCI Frequency
When set to [Enabled], the system will remove (turn off) clocks from empty DIMM and
PCI slots to minimize the electromagnetic interference (EMI). CPU Voltage / Momory Voltage / NB Voltage / Hypertransport Voltage
These items dispaly the power status of CPU, Memory, FSB and chipset. Read-only. Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses create 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,
set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are
overclocking because even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.1.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,
select the value of Spread Spectrum for EMI reduction.
2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.
3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.Important

3-22 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:
Selecting Ok and 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:
Selecting Ok and pressing Y loads the default factory settings for optimal system
performance.Load Fail-Safe/ Optimized Defaults

3-23BIOS Setting Password
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.
