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

Introduction

Expansion Slots

The system board is equipped with 1 AGP slot, 4 dedicated PCI

slots and 1 shared PCI/CNR slot.

The AGP slot only supports 1.5V AGP 4x (1066MB/sec. bandwidth)

add-in cards. AGP is an interface designed to support high

performance 3D graphics cards for 3D graphics applications. It

handles large amounts of graphics data with the following features:

 Pipelined memory read and write operations that hide memory

access latency.

 Demultiplexing of address and data on the bus for nearly 100

percent efficiency.

CNR (Communication and Networking Riser) is an interface that

supports multi-channel audio, V.90 analog modem, phone-line based

networking or 10/100 Ethernet based networking riser board.

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.

Depending on the setting in the Soft-Off By PWR-BTTN field of

the Power Management Setup, this switch will allow the system to

enter the Soft-Off or Suspend mode.

Wake-On-Ring

This feature allows the system that is in the Suspend mode or Soft

Power Off mode to wake-up/power-on to respond to calls coming

through an internal or external modem. Refer to Wake-On-Ring

Connector in chapter 2 and Resume On Ring in the Power

Management Setup section in chapter 3 for more information.

Important:

If you are using a modem add-in card, the 5VSB power source

of your power supply must support

≥

720mA.
