Introduction
Expansion Slots
The system board is equipped with 1 dedicated AGP slot and 5
dedicated PCI slots. All PCI slots are bus masters. 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; delivering up to 533MB/
sec. bandwidth for 3D graphics applications.
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.
ATX Double Deck Ports
2 USB ports
2 DB-9 serial ports
1 DB-25 parallel port
1 min-DIN-6 PS/2 mouse port
1 min-DIN-6 PS/2 keyboard port
Connectors
1 connector for IrDA interface
1 connector for 2 additional external USB ports
2 IDE connectors
1 floppy connector
1 20-pin ATX power supply connector
1 Wake-On-Ring connector
1 Wake-On-LAN connector
1 chassis fan connector, 2 CPU fan connectors for CPU Fan1
and CPU Fan2

Introduction
1.1.3 Intelligence
Automatic CPU/Chassis Fan Off
The CPU and chassis fans will automatically turn off once the
system enters the Suspend mode.
Dual Function Power Button
Depending on the setting in the BIOS 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 for more information.
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC. Your LAN card must
support the remote wakeup function.
Important:
The 5VSB power source of your power supply must support
≥
720mA (minimum).
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
ACPI
The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management.
