1.2 Special Features of the System Board
PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses
the ability to scale speeds by forming multiple lanes. The system
board currently supports the physical layer of x1 and x16 lane
widths.
The x1 PCI Express lane supports transfer rate of 2.5 Gigabytes
(250MBbps) per second. The PCI Express architecture also provides
a high performance graphics infrastructure by doubling the capability
of the existing AGP 8x designs over a x16 PCI Express lane that
provides 4 Gigabytes per second transfer rate.
Hyper-Threading Technology Functionality Requirements
The system board supports Intel processors with Hyper-Threading
Technology. Enabling the functionality of Hyper-Threading Technology
for your computer system requires ALL of the following platforms.
Components:
• CPU - an Intel®Pentium®4 Processor with HT Technology
• Chipset - an Intel®chipset that supports HT Technology
• BIOS - a BIOS that supports HT Technology and has it enabled
• OS - an operating system that includes optimizations for HT
Technology
Please refer to Appendix A for information about enabling the
functionality of the Hyper-Threading Technology. For more information
on Hyper-Threading Technology, go to: www.intel.com/info/
hyperthreading.
Performance Acceleration Technology (PAT)
PAT performs data transactions directly from the CPU to the system
memory, bypassing the normal path of operation. This reduces the
MCH timing therefore providing improved system performance.

1
Introduction
11
CPU Overheat Protection
CPU Overheat Protection has the capability of monitoring the CPU’s
temperature during system boot up. Once the CPU’s temperature
exceeded the temperature limit pre-defined by the CPU, the system
will automatically shutdown.This preventive measure has been added
to protect the CPU from damage and insure a safe computing
environment.
DDR2
DDR2 is a higher performance DDR technology whose data transfer
rate delivers bandwidth of 4.3 GB per second and beyond. That is
twice the speed of the conventional DDR without increasing its
power consumption. DDR2 SDRAM modules work at 1.8V supply
compared to 2.6V memory voltage for DDR modules. DDR2 also
incorporates new innovations such as the On-Die Termination (ODT)
as well as larger 4-bit pre-fetch against DDR which fetches 2 bits
per clock cycle.
CMOS Reloaded
CMOS Reloaded is a technology that allows storing multiple user-
defined BIOS settings by using the BIOS utility to save, load and
name the settings. This is especially useful to overclockers who
require saving a variety of overclocked settings and being able to
conveniently switch between these settings simultaneously.
Karajan Audio Card
The Karajan audio add-in card at the rear I/O panel supports 8-
channel audio output via the audio jacks on the card.
S/PDIF
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. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device.The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.

Introduction

12
Serial ATA Interface with RAID
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s. The system board allows configuring RAID
on SATA drives. It supports RAID 0, RAID 1 and JBOD.
IEEE 1394 Interface
IEEE 1394 is fully compliant with the 1394 OHCI (Open Host
Controller Interface) 1.1 specification. It supports up to 63 devices
that can run simultaneously on a system. 1394 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. 1394 supports both Plug-and-Play and hot
plugging.
IrDA Interface
The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 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.
Dual Function Power Button
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.

1
Introduction
13
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
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥ 720mA.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is supported via the onboard LAN port or
via a PCI LAN card that uses the PCI PME (Power Management
Event) signal. However, if your system is in the Suspend mode, you
can power-on the system only through an IRQ or DMA interrupt.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-PS/2 Keyboard/Mouse
This function allows you to use the PS/2 keyboard or PS/2 mouse
to power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.

Introduction
1
14
Wake-On-USB Keyboard/Mouse
This function allows you to use a USB keyboard or USB mouse to
wake up a system from the S3 (STR - Suspend To RAM) state.
Important:
• If you are using the Wake-On-USB Keyboard/Mouse
function for 2 USB ports, the 5VSB power source of your
power supply must support ≥ 1.5A.
• If you are using the Wake-On-USB Keyboard/Mouse
function for 3 or more USB ports, the 5VSB power source
of your power supply must support ≥ 2A.
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 STR
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. Currently, only Windows®®
®®
®2000/XP supports
the ACPI function. ACPI when enabled in the Power Management
Setup will allow you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting “Standby”
when you shut down Windows®®
®®
®2000/XP without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of
storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The
operating session will resume exactly where you left off the next time
you power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 1A.
