Introduction
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.

Power Supply Connector
The system board is equipped with an ATX power supply connector.
Using an ATX power supply, you can either shut down your com-
puter by pressing the Power button located on the front bezel of
your computer or by executing the Shut Down command under the
Windows95 operating system.Your system will then enter the Soft
Off state.
To power-on your system automatically, enable Resume On Alarm
in the Power Management Setup of the Award BIOS.This will allow
you to set the date and time you would like your system to power-
on.
1.1.2 Technology
AGP (Accelerated Graphics Port)
The system board is equipped with 1 AGP slot. 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. AGP in this PentiumII processor based system
board will deliver faster and better graphics with your PC.
PC SDRAM (Synchronous Dynamic Random Access Memory)
PC SDRAM uses a fast memory interface technology to meet the
memory bandwidth requirements of Intel processors and chipset.
This technology includes using the clock on the chip to synchronize
with the CPU clock so that the timing of the memory chips and the
timing of the CPU are synchronized. Please refer to Intels web site
for more information on PC SDRAM.
Creative SB-LINK
The system board is equipped with a Creative SB-LINK connector.
SB-LINK serves as a bridge between the system board and a
Creative PCI sound card to deliver Sound BlasterAWE64D
performance. Refer to SB-LINK Connector in Chapter 2 for more
information.

Introduction
Ultra DMA/33 Bus Master IDE
Synchronous Ultra DMA mode provides data transfer rate up to a
maximum of 33MB/sec, which is twice the data transfer rate of
Enhanced IDE or ATA-2. This enables the CPU to operate more
efficiently when handling simultaneous events.
ECC (Error Checking and Correction)
ECC is a function that allows the system to recover from memory
failure. It detects single-bit and multiple-bit errors and corrects single-
bit error thus providing uninterrupted processing of data. To use this
function, you must install DIMM that supports parity.
ACPI (Advanced Configuration and Power Interface)
The system board is designed to meet the ACPI 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.
PC 97 Compliant
The system board is PC 97 compliant. This will optimize your PC
system to run Windows95 and Windows NTand future versions
of these operating systems.
1.1.3 Intelligence
Dual Function Power Button
Depending on the setting in the BIOS setup, this switch will allow
your system to enter the Soft-Off or Suspend mode. Soft-Off By
PWR-BTTN in the Power Management Setup (Chapter 3) allows
you to select the method of powering off your system.
External Modem Wake-up/Ring-on
The Modem Wake-Up feature allows the sleeping (Suspend mode)
PC to wake-up to respond to incoming calls. The Modem Ring-on
feature allows the Soft Power Down (Soft-Off) PC to power-on to
respond to incoming calls. Enable this function in the Resume On
Ring field of the Power Management Setup (Chapter 3).

Note:
This feature supports external modem only.
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. Set the date and
time you would like your system to power-on in the Resume On
Alarm field of the Power Management Setup (Chapter 3).
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to wake up a Soft
Power Down (Soft-Off) PC. To use the Wake-On-LAN function,
make sure your LAN card also support this function. Refer to the
Wake-On-LAN Connector section (Chapter 2) and Resume On
LAN field in the Power Management Setup (Chapter 3).
Important:
The 5VSB power source of your power supply must support
≥ 720mA (minimum).
Wake-On-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or mouse to power-on
the system. Refer to Jumper Settings for Wake-On-Keyboard/Wake-
On-Mouse in Chapter 2 and Keyboard/Mouse Power On in the
Integrated Peripherals setup of the Award BIOS in Chapter 3 for
more information.
Important:
The power button will not function once a keyboard password
has been set in the KB Power On Password field of the
Integrated Peripherals setup. You must type the correct
password to power-on the system.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive. If an attempt is made to write to the boot
sector or partition table of the hard disk drive, the BIOS will halt the
system and an error message will appear. Refer to the Virus
Warning field in the BIOS Features Setup (Chapter 3).
