3-20 used, the onboard MC’97 (Modem Codec’97) controller will be enabled; if not,
it is disabled. Disable the controller if you want to use other controller cards to
connect to a modem. Settings: Auto, Disabled.
Floppy  Controller
This is used to enable or disable the onboard Floppy controller.
Serial Port A/B
These items specify the base I/O port addresses of the onboard Serial Port 1
(COM A)/Serial Port 2 (COM B).  Selecting Auto allows AMIBIOS to automati-
cally determine the correct base I/O port address. Settings: Auto, 3F8/COM1,
2F8/COM2, 3E8/COM3, 2E8/COM4 and Disabled.
Serial PortB Mode
This item sets the operation mode for Serial Port B. Settings: Normal,
1.6uS, 3/16 Baud and ASKIR (the last three operation modes are setting
options for IR function).
IR  Duplex Mode
This field specifies a duplex value for the IR device connected to COM B.
Full-Duplex mode permits simultaneous two-direction transmission. Half-
Duplex mode permits transmission in one direction only at a time. Settings:
Half Duplex and Full Duplex.
IR Pin Select
Set to IRRX/IRTX when using an internal IR module connected to the IR
connector. Set to SINB/SOUTB. when connecting an IR adapter to COM
B.
Parallel Port
This field specifies the base I/O port address of the onboard parallel port.
Selecting Auto allows AMIBIOS to automatically determine the correct base I/ OptionDescription
AutoBIOS will automatically determine whether to enable the
onboard Floppy controller or not.
EnabledEnables the onboard Floppy controller.
DisabledDisables the onboard Floppy controller.

3-21 O port address. Settings: Auto, 378, 278, 3BC and Disabled.
Parallel  Port Mode
This item selects the operation mode for the onboard parallel port: ECP,
Normal, Bi-Dir or EPP.
EPP Version
The item selects the EPP version used by the parallel port if the port is set
to EPP mode. Settings: 1.7 and 1.9.
IRQ
When Parallel Port is set to Auto, the item shows Auto indicating that
BIOS determines the IRQ for the parallel port automatically.
DMA Channel
This feature needs to be configured only when Parallel Port Mode is set
to the ECP mode. When Parallel Port is set to Auto, the field will show
Auto indicating that BIOS automatically determines the DMA channel for
the parallel port.
OnBoard  Midi Port
The field specifies the base I/O port address for the onboard Midi Port.
Midi IRQ Select
The item is used to select the IRQ line for onboard Midi port.
OnBoard Game Port
This item is used to specify the address for the onboard game port.

3-22Hardware Monitor Setup
This section describes how to set the CPU FSB frequency, monitor the current
hardware status including CPU/system temperatures, CPU/System Fan speeds,
Vcore etc. Monitor function is available only if there is hardware monitoring
mechanism onboard.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.
CPU FSB Clock (Mhz)
This setting allows you to select the CPU Front Side Bus clock frequency.
Setting options: 100MHz~200MHz at 1MHz increment.
Spread  Spectrum
When the motherboard 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, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be-
cause even a slight jitter can introduce a temporary boost in clockspeed which

CPU Vcore Adjust
This setting is used to adjust the CPU core voltage (Vcore), making overclocking
possible.
DDR/AGP  Power  Voltage
The item is to adjust the DDR/AGP voltage to increase the DDR/AGP rate.
Modifying the setting may lead to unstable system, so changing the DDR/
AGP Vcore for long-term use is not recommended.

These items display the current status of all of the monitored hardware de-
vices/components such as system voltages, temperatures and fan speeds.

3-24 Load High Performance/BIOS Setup DefaultsThe two options on the main menu allow users to restore all of the BIOS
settings to High Performance defaults or BIOS Setup defaults.  The High Per-
formance Defaults are the default values set by the mainboard manufacturer
for the best system performance but probably will cause a stability issue.  The
BIOS Setup Defaults are the default values also set by the mainboard manufac-
turer for stable performance of the mainboard.
When you select Load High Performance Defaults, a message as below appears:
Pressing ‘Y’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.
The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the sys-
tem performance. Therefore, a high-end system configuration is a
must, which means you need high-quality VGA adapter, RAM and
so on. We don’t recommend that users should apply the high
performance defaults in their regular systems. Otherwise, the sys-
tem may become unstable or even crash. If the system crashes or
hangs after enabling the feature, please CLEAR CMOS DATA to
resolve the problem. For more information, refer to “Clear CMOS
Jumper:JBAT1” in Chapter 2.WARNING!When you select Load BIOS Setup Defaults, a message as below appears:
Pressing ‘Y’ loads the default values that are factory settings for stable system
performance.

3-25 Supervisor/User PasswordWhen you select Supervisor Password, 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.
Additionally, when a password is enabled, you can also have AMIBIOS to
request a password each time the system is booted. This would prevent unau-When you select User Password, a message as below will appear on the screen:

MSI Smart KeyA
If security is important to you, the MSI Smart Key is the best solution to
prevent your data in the computer from being accessed by unauthorized people.
In the public workspace, the passwords (BIOS password, system
password, etc.) are not enough to keep your privacy.  Do you believe that a
hacker can easily enter your computer and monitor your confidential data?  It
happens everyday, everywhere; you just do not know...  A password only
stops them at the first gate.  If this protection is broken, what else can you rely
on?
The MSI Smart Key is a hardware device that provides you the com-
plete and perfect protection on your system.  Once the key is installed and
setup, any unauthorized user absolutely can not access and use your computer
without the key.  The computer needs the key to boot up, and the operating
system needs the key to work normally.  Furthermore, if you have to leave
your desktop for a while, you can simply unplug the key to keep your system
in a safest status.TOPICS
