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 memor y

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.

connector on the system board allows you to connect the optional

Introduction



3rd and 4th USB ports. These optional USB por ts, which are

mounted on a card-edge bracket, will be provided as an option.

USB allows data exchange between your computer and a wide

range of simultaneously accessible external Plug and Play peripherals.

BIOS

 Award BIOS, Windows® 98/ 000/ME Plug and Play compatible

 Supports SCSI sequential boot-up

 Flash EPROM for easy BIOS upgrades

 Supports DMI .0 function

Desktop Management Interface (DMI)

The system board comes with a DMI .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.

1.1.2 System Healt Monitor Functions

The system board is capable of monitoring the following system

health conditions.

 Monitors CPU/system temperature and overheat alarm

 Monitors 5VSB/VBAT/3.3V/5V/±1 V/CPU voltages and failure

alarm

 Monitors the fan speed of the CPU fan, system fan and second

fan; and failure alarm

 Automatic system fan and second fan on/off control

 Read back capability that displays temperature, voltage and fan

speed

 Opened chassis alarm

Refer to the PC Health Status section in chapter 3 and the

Hardware Doctor section in chapter 4 for more information.
