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 usu-
ally 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 am-
plifiers and speakers and to digital recording devices like CD re-
corders.

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.
Wake-On-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or PS/2 mouse to
power-on the system.
Important:
The 5VSB power source of your power supply must support
≥ 720mA.
Wake-On-USB Keyboard
The Wake-On-USB Keyboard function allows you to use a USB
keyboard to wake up a system that is in the S3 (STR - Suspend
To RAM) state.
Important:
• If you are using the Wake-On-USB Keyboard 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 function for 3
or more USB ports, the 5VSB power source of your power
supply must support ≥ 2A.
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, internal 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 ≥ 720mA.

Introduction

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, via a PCI LAN card that uses the PCI PME (Power Manage-
ment Event) signal or via a LAN card that uses the Wake-On-
LAN connector. 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.
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 Con-
figuration and Power Interface) specification. ACPI has energy sav-
ing features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management. Currently, only Windows®®
®®
®98SE/2000/ME/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®®
®®
®98SE/2000/ME/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.

2.2 System Memory
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.
The system board is equipped with two 184-pin DDR SDRAM
DIMM (Dual In-line Memory Module) sockets that support 2.5V
DDR SDRAM DIMM. Double Data Rate SDRAM (DDR SDRAM)
is a type of SDRAM that doubles the data rate through reading
and writing at both the rising and falling edge of each clock. This
effectively doubles the speed of operation therefore doubling the
speed of data transfer. Refer to chapter 1 (System Memory section)
for detailed specification of the memory supported by the system
board.
BIOS Setting
Configure the system memory in the Advanced Chipset Features
submenu of the BIOS.
