							3-21 BIOS SetupSpread 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,
select the desired range for EMI reduction. Remember to disable Spread Spectrum
function if you are overclocking, because even a slight jitter can introduce a tempo-
rary boost in clock speed which may just cause your overclocked processor to lock
up.
Adjust CPU FSB Frequency
This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and
overclock the processor by adjusting the FSB clock to a higher frequency. Setting
options:For CPU FSB200: [200]~[500]
Adjust PCI Express Frequency
This item allows you to select the PCI Express frequency (in MHz). Select the number
between [100]~[133] for needed frequency.
CPU Dynamic OverClocking
Dynamic Overclocking Technology is the automatic overclocking function, included in
the MSITM
’s newly developed CoreCellTM 
Technology. It is designed to detect the load
balance of CPU while running programs, and to adjust the best CPU frequency
automatically. When the motherboard detects CPU is running programs, it will speed
up CPU automatically to make the program run smoothly and faster. When the CPU 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 frequency need to be boosted up to enhance the overall performance.
Setting options:
[Disabled]Disable Dynamic Overclocking function.
[Private]1st level of overclocking, increasing the CPU frequency by 2%.
[Sergeant]2nd level of overclocking, increasing the CPU frequency by 3%.
[Captain]3rd level of overclocking, increasing the CPU frequency by 4%.
[Colonel]4th level of overclocking, increasing the CPU frequency by 5%.
[General]5th level of overclocking, increasing the CPU frequency by 6%.
[Commander]6th level of overclocking, increasing the CPU frequency by 7%.

1.Even though the Dynamic Overclocking Technology is more stable
than manual overclocking, basically, it is still risky. We suggest
user to make sure that your CPU can afford to overclock regularly
first. If you find the PC appears to be unstable or reboot
incidentally, its better to disable the Dynamic Overclocking or to
lower the level of overclocking options. By the way, if you need to
conduct overclocking manually, you also need to disable the Dy-
namic OverClocking first.
2.Meanwhile, there are two functions to protect users system from
crashing.
-There is a safe key Ins in BIOS. In case the overclocking
fails, you can press Ins key while system rebooting to
restore to the BIOS defaults.
-If the system incidentally reboot for four times, the BIOS will
also be restored to the defaults.Adjust CPU Ratio
This item allows you to adjust the CPU ratio. Setting range is from [8X]  to [50X].
Auto Detect PCI Clock
This item is used to auto detect the PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty PCI slots to minimize the electromagnetic interfer-
ence (EMI). Settings: [Enabled], [Disabled].
Adjust PCI Frequency
This item allows you to select the PCI frequency (in MHz). In default this value will
change automatically in accordance with the setting of Adjust CPU FSB Frequency.
However, you may adjust the desired fixed PCI frequency you like by using the  &
 key. Setting option: [33.3]. 
						

							3-23 BIOS SetupLoad 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 [OK] loads the BIOS default values for the most stable, minimal system
performance.
When you select Load Optimized Defaults, a message as below appears:
Pressing [OK] loads the default factory settings for optimal system performance. 
						

							3-24MS-7176 ATX Mainboard
When you select this functions, 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.BIOS Setting Password

short-cut icon in the system trayshort-cut path in the start-up menu
(path: Start-->Programs-->MSI-->DigiCell) DigiCell, the most useful and powerful utility that MSI has spent much
research and efforts to develop, helps users to monitor and configure all the
integrated peripherals of the system, such as audio program, power
management, MP3 files management and communication / 802.11g WLAN
settings. Moreover, with this unique utility, you will be able to activate the
MSI well-known features, Live Update and Core Center, which makes it
easier to update the BIOS/drivers online, and to monitor the system hard-
ware status (CPU/Fan temperature and speed) or to overclock the CPU/
memory.
Once you have your DigiCell installed (locate the setup source file in
the setup CD accompanying with your mainboard, path: Utility --> MSI Util-
ity --> MSI DigiCell), it will have an icon         in the system tray, a short cut
icon on the desktop, and a short cut path in your “Start-up” menu. You may
double-click on each icon to enable DigiCell.

Terminology
Here are the introduction of WLAN / AP communication terminology.
WEP KeyIn the wireless network environment, the administrator can set up password
(Network Key) to protect the network from being attacked or unauthorized
access. When building the network, you can set up 4 sets of WEP keys,
which can be 5 characters (10 hex-adecimal digital) or 13 characters (26
hex-adecimal digital) and specify one of them to use.
Ad-hoc ModeAn Ad-hoc network is a local area network or other small network, especially
one with wireless or temporary plug-in connections, in which some of the
network devices are part of the network only for the duration of a communi-
cations session. Users in the network can share files, print to a shared
printer, and access the Internet with a shared modem. In this kind of network,
new devices can be quickly added; however, users can only communicate
with other wireless LAN computers that are in this wireless LAN workgroup,
and are within range.
Infrastructure ModeThe difference between Infrastructure network and Ad-hoc network is that
the former one includes an Access Point. In an Infrastructure network, the
Access Point can manage the bandwidth to maximize bandwidth utilization.
Additionally, the Access Point enables users on a wireless LAN to access an
existing wired network, allowing wireless users to take advantage of the
wired networks resources, such as Internet, email, file transfer, and printer
sharing. The scale and range of the Infrastructure networking are larger and
wider than that of the Ad-hoc networking.
