						■	Electrostatic discharge (ESD) is the sudden and momentary electric current
							that flows between two objects at different electrical potentials. Normally it
							comes out as a spark which will quickly damage your electronic equipment.
							Please wear an electrostatic discharge (ESD) wrist strap when handling
							components such as a motherboard, CPU or memory.
						■	Ensure that the DC power supply is turned off before installing or removing
							CPU, memory, expansion cards or other peripherals. It is recommended to
							unplug the AC power cord from the power supply outlet. Failure to unplug
							the power supply cord may result in serious damage to your system.

							Please carefully read the following procedures to install your computer :
						■	It is suggested to select high-quality, certified fans in order to avoid damage
							to the motherboard and CPU due to high temperature. Never turn on the
							computer if the CPU fan is not properly installed.
						■	We cannot guarantee that your system can operate normally when your
							CPU is overclocked. Normal operation depends on the overclocking capac-
							ity of your device.
						■	If there is any, when connecting USB, audio, RS232 COM, IrDA or S/PDIF
							cables to the internal connectors on the motherboard, make sure their
							pinouts are matching with the connectors on the motherboard. Incorrect con-
							nections might damage the motherboard.
						■	When handling the motherboard, avoid touching any metal leads or connec-
							tors.

Clear CMOS Jumper: CLR_CMOS

The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data, date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to factory default when the BIOS settings were mistakenly modified.

The steps to clear CMOS data are :

1.Turn off the computer, unplug the power cord from the power outlet.

2.Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them. This will clear CMOS data.

3.Return the setting to its original with pins 2-3 closed.

4.Plug in the power cord to your computer and turn it on.

Each item in the main menu is explained below:

►System Information

It displays the basic system configuration, such as BIOS ID, CPU Name, memory size plus system date, time and Floppy drive. They all can be viewed or set up through this menu.

►Advanced BIOS Features

The advanced system features can be set up through this menu. There are boot up settings.

►Fox Central Control Unit

Some special proprietary features (such as overclocking) can be set up through this menu.

►Advanced Chipset Features

The values for the chipset can be changed through this menu, and the system performance can be optimized.

►Integrated Peripherals

All onboard peripherals can be set up through this menu. There are IDE devices, Super I/O devices such as Serial I/O and other USB devices... etc.

	► Power Management Setup
	All the items related with Green function features can be set up through this menu.
	► PC Health Status
	This setup enables you to read/change Fan speeds, and displays temperatures and voltages
	of your CPU/System.
	► BIOS Security Features
	The Supervisor/User password can be set up through this menu to prevent unauthorized use
	of your computer. If you set a password, the system will ask you to key in correct password
	before boot or access to Setup.
3	► Load Optimal Defaults
	The optimal performance settings can be loaded through this menu. However, it may offer bet-
	ter performance in some ways (such as less I/O cards, less memory ...etc.), still, it may cause
	problem if you have more memory or I/O cards installed. It means, if your system loading is
	heavy, set to optimal default may sometimes come out an unstable system. What you need
	now is to adjust BIOS setting one by one, trial and error, to find out the best setting for your

current system.

► Save & Exit Setup

Save setting values to CMOS and exit.

► Exit Without Saving

Do not change anything and exit the setup.

►IDE Detect Time Out

This item is used to select the time out value for detecting ATA/ATAPI devices. If the checking time is over the set value, the system will skip it.

►MPS Revision

This feature is only applicable to multiprocessor motherboards as it specifies the version of the MPS that the motherboard will use. The MPS is a specification by which PC manufacturers design and build CPU architecture systems with two or more processors. MPS 1.1 was the original specification. MPS version 1.4 adds extended configuration tables for improved support of multiple PCI bus configurations and greater expandability in the future. In addition,

MPS 1.4 introduces support for a secondary PCI bus without requiring a PCI bridge. If your operating system comes with support for MPS 1.4, you should keep the setting as the default 1.4. You also need to enable MPS 1.4 support if you need to make use of the secondary PCI bus on a motherboard that doesn't come with a PCI bridge. You should only leave it as 1.1 only if you are running an older operating system that only supports MPS 1.1.

►PCI Latency Timer

This item is used to set the PCI latency timer. The value is in unit of PCI cycle for PCI device latency timer register. Setting values are 32, 64, 96, 128, 160, 192, 224, 248.

This feature controls how long each PCI device can hold the bus before another takes over. The larger the value, the longer the PCI device can retain control of the bus. Low values for the PCI Latency Timer will reduce the effective PCI bandwidth while higher values means every PCI device will have to wait longer before they can get access to the bus, but when they do get access, they can conduct their transactions for a longer time. Normally, a default value of 64 cycles is set. Some PCI devices may not agree with longer latency times so if you start facing problems like stuttering sound or a less responsive system, reduce the latency. Higher values will actually reduce performance as too much time may be allocated to each PCI device to the disadvantage of other devices on the bus.

►Quiet Boot

This item is used to enable/disable the quiet boot.
