Caution

To avoid damage to the system:
 Use the correct AC input voltage range.

To reduce the risk of electric shock:
 Unplug the power cord before removing the system chassis

cover for installation or servicing. After installation or servicing,
cover the system chassis before plugging the power cord.

Battery:
 Danger of explosion if battery incorrectly replaced.
 Replace only with the same or equivalent type recommend by

the manufacturer.

 Dispose of used batteries according to the battery

manufacturers instructions.

Joystick or MIDI port:
 Do not use any joystick or MIDI device that requires more than

10A current at 5V DC. There is a risk of fire for devices that
exceed this limit.

FCC and DOC Statement on Class B

This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:

 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and the receiver.
 Connect the equipment into an outlet on a circuit different from

that to which the receiver is connected.

 Consult the dealer or an experienced radio TV technician for

help.

Notice:

1. The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority
to operate the equipment.

2. Shielded interface cables must be used in order to comply with
the emission limits.

1.5.9 Frequency/Voltage Control

The frequency ratio of some processors may have been locked by the
manufacturer. If you are using this kind of processor, setting an extended
ratio for the processor will have no effect. The system will instead use its
factory default ratio.

Overclocking may result in the processors or systems instability and is not
guaranteed to provide better system performance.

Expansion Slots

The system board is equipped with 1 AGP slot and 6 PCI slots.

AGP is an interface designed to support high performance 3D
graphics cards. It utilizes a dedicated pipeline to access system
memory for texturing, z-buffering and alpha blending. The universal
AGP slot supports AGP 8x with up to 2132MB/sec. bandwidth and
AGP 4x with up to 1066MB/sec. bandwidth for 3D graphics
applications. AGP in this system board will deliver faster and better
graphics to your PC.

Onboard Audio Features

 AC'97 2.2 extension compliant codec
 Supports Microsoft® DirectSound/DirectSound 3D
 AC97 supported with full duplex, independent sample rate

converter for audio recording and playback
 S/PDIF-in/out interface (S/PDIF-in is optional)
 6-channel audio output

S/PDIF

The system board is equipped with the S/PDIF (Sony/Philips Digital
Interface) digital audio interface. S/PDIF is a standard audio file
transfer format that transfers digital audio signals to a device without
having to be converted first to an analog format. This prevents the
quality of the audio signal from degrading whenever it is converted
to analog.

Onboard LAN Features (NS80-EA and NS80-EL only)

 Uses Phy fast ethernet controller
 Integrated IEEE 802.3, 10BASE-T and 100BASE-TX compatible

PHY
 32-bit PCI master interface
 Integrated power management functions
 Full duplex support at both 10 and 100 Mbps
 Supports IEEE 802.3u auto-negotiation
 Supports wire for management

IEEE 1394A Interface (NS80-EA only)

 Uses Realtek RTL8801 chip
 Supports three 100/200/400 Mb/sec ports

The Realtek RTL8801 Phy 1394A controller works with the SiS 963
chip to support IEEE 1394A. It is fully compliant with the 1394A
OHCI (Open Host Controller Interface) 1.1 specification. 1394A is a
fast external bus standard that supports data transfer rates of up to
400Mbps. In addition to its high speed, it also supports isochronous
data transfer which is ideal for video devices that need to transfer
high levels of data in real-time. 1394A supports both Plug-and-Play
and hot plugging allowing devices to be attached or removed from
the system, even with the power on.

PCI Bus Master IDE Controller

 Two PCI IDE interfaces support up to four IDE devices
 Supports ATA/33, ATA/66, ATA/100 and ATA/133 hard drives
 UDMA Modes 3, 4, 5 and 6 Enhanced IDE (data transfer rate

up to 133MB/sec.)
 Bus mastering reduces CPU utilization during disk transfer
 Supports ATAPI CD-ROM, LS-120 and ZIP

IrDA Interface

The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices.

USB Ports

The system board supports 6 USB 2.0/1.1 ports. USB 1.1 supports
12Mb/second bandwidth while USB 2.0 supports 480Mb/second
bandwidth providing a marked improvement in device transfer
speeds between your computer and a wide range of simultaneously
accessible external Plug and Play peripherals.

BIOS

 Award BIOS, Windows® 98/2000/ME/XP Plug and Play

compatible
 Supports SCSI sequential boot-up
 Flash EPROM for easy BIOS upgrades
 Supports DMI 2.0 function
 2Mbit flash memory

Desktop Management Interface (DMI)

The system board comes with a DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier. Refer to chapter 4 for instructions on using
the DMI utility.

The chassis fan will automatically turn off once the system enters the
Suspend mode.

Dual Function Power Button

Depending on the setting in the Soft-Off By PWRBTN field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.

Wake-On-PS/2 Keyboard/Mouse

This function allows you to use the PS/2 keyboard or PS/2 mouse
to wake up a system from the S3/S4/S5 state.

Important:

 If you forgot the password, you must power-off the system,

unplug the power cord and clear the CMOS data. Follow
the settings in the Clear CMOS Data section in chapter 1.
