							3-22MS-7210 Micro-ATX MainboardH/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.
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.
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.MSI Reminds You...
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 suit-
able Spread Spectrum value, please consult your local EMI regulation.
3.Remember to disable Spread Spectrum if you are overclocking be-
cause even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up. 
						

							3-23 BIOS SetupChassis 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: [Enabled], [Reset], [Disabled].
CPU/System Temperature, CPU FAN Speed, Vcore, +3.3 V, +5.0 V, +12.0V
These items display the current status of all of the monitored hardware devices/
components such as CPU voltages, temperatures and all fans’ speeds. 
						

							3-24MS-7210 Micro-ATX MainboardLoad Optimized DefaultsThe option on the main menu allow users to restore all of the BIOS settings to
the default Optimized values. The Optimized Defaults are the default values set by the
mainboard manufacturer specifically for optimal performance of the mainboard.
When you select Load Optimized Defaults, a message as below appears:
Pressing [Y] loads the default factory settings for optimal system performance. 
						

							3-25 BIOS SetupBIOS 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.

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 V-Center, which makes it easier
to update the BIOS/drivers online, and to monitor the system hardware sta-
tus (CPU/Fan temperature and speed).
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. 
						

							4-2MS-7210 Micro-ATX MainboardBefore using this utility, it is required to have all the integrated peripherals/cards (LAN
card, Wireless LAN card, MegaStick... etc.) and all the necessary drivers (onboard
LAN driver, audio driver, V-Center, Live Update... etc.) installed correctly.
The icon representing each item will be lit up if it is inserted/installed correctly and
properly. Otherwise, the icon will remain gray and user is not able to view the
functionality/connection of that item.Main

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.
