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-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.
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.
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. Refer to Wake-On-LAN Connector in
chapter 2 for more information.
Important:
The 5VSB power source of your power supply must support a
minimum of 1.5A.
Wake-On-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or PS/2 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 section 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 submenu. You must type
the correct password to power-on the system. If you forgot
the password, power-off the system and remove the

battery. Wait for a few seconds and install it back before
powering-on the system.
 The 5VSB power source of your power supply must
support a minimum of 1.5A.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs. Refer to PWR Lost Resume State in the Integrated
Peripherals section in chapter 3 for more information.
Year 2000 Compliant
 Supports hardware Y2K function.
 Supports hardware Random Number Generator (RNG) to en-
able a new security and manageability infrastructure for PC.
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. Currently, only Windows®98 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®98 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. Refer to Using the Suspend to RAM
Function in appendix A for more information.
Important:
The 5VSB power source of your power supply must support a
minimum of 1.5A.

2.2 System Memory
The two 184-pin SRIMM sockets on the system board uses RIMMTM
modules for memory expansion. A RIMMTM module may come with
4, 8, 12, 16 or more devices. A device refers to 1 RDRAM chip. In
other words, a module with 8 devices means the module has 8
RDRAM (Rambus Dynamic RAM) chips on it. A device provides
1.6GB/sec bandwidth which is several times the bandwidth available
from a SDRAM. An example of a RIMMTM module with 8 devices is
shown below.
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.
When you purchase a RIMMTM module, the devices on the module
are not visible unlike the one shown above. This is because the
module has already been packaged with a heatsink. Make sure you
know the number of devices and the RDRAM technology used
when you purchase the module because these information are
important when you configure your system memory. Please read the
following sections carefully.

For example, if a module that uses the 64Mbit/72Mbit technology
has 8 devices - then the memory size of a device multiplied by the
number of devices will be the total memory size of the module.

2.2.1 Determining the Memory Size of a RIMMTM Module
The memory size of a RIMMTM module will depend on the memory
size of a device and the number of devices used; and the memory
size of a device will depend on the RDRAM technology used.
2.2.3 Important Installation Instructions
Important:
Certain rules must be followed when installing RIMMTM
modules to obtain optimum system performance.
Rule 1. The RIMMTM module with the most devices must be
installed into the RIMM1 socket.
Mem. Size of a Device x 32 Devices = Max. Memory
8MB x 32 = 256MB
16MB x 32 = 512MB
32MB x 32 = 1GB
RDRAM Technology
64Mbit/72Mbit
128Mbit/144Mbit
256Mbit/288Mbit
2.2.2 Determining the Maximum System Memory Size
The maximum memory size supported by the system will depend
on the memory size of a device (relevant to its RDRAM technology)
multiplied by 32. Why 32? This is because a system has only 1
Rambus Channel and a Rambus Channel supports up to 32 devices
only.

2
16
Hardware Installation
Rule 2. Regardless of the number of RIMMTM modules used,
the total number of devices must not exceed 32
devices.
Rule 3. Due to RDRAMs signal routing, all SRIMM sockets
must be populated with modules.This is to allow the
Direct Rambus Channel to function properly. If a
socket is not populated with RIMMTM module, YOU
MUST install it with CRIMM (continuity module). If, at
any time, you wish to upgrade the system memory,
remove the CRIMM that is next to the existing
RIMMTM module and replace it with another RIMMTM
module - always taking into consideration rule 1.
RIMM1 socket is installed with
a RIMM module.
RIMM2 socket is installed with
a CRIMM module.
RIMM1 and RIMM2 sockets
are installed with RIMM
modules.

The CRIMM module included in the system board package looks
similar to the one shown below..
The figure below shows a clearer illustration of the RDRAM
signal routing principle.
2.2.4 Installing the RIMMTM Module
A RIMM module simply snaps into a RIMM socket on the system
board. Pin 1 of the RIMM module must correspond with Pin 1 of
the socket.

Hardware Installation
1. Pull the tabs which are at the ends of the socket to the side.
2. Position the RIMM above the socket with the notches in the
module aligned with the keys on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated.The tabs will hold the RIMM in place.
2.3 Processor Installation
The system board is equipped with a 242-pin processor slot (Slot
1). The ends of the slot are installed with the Universal Retention
Mechanism (URM). URM is used to hold an Intel®SECC, SECC2 or
SEPP processor onto the slot.
Warning:
The processor must be kept cool by using a fan with heatsink.
Leave certain space clearances to maintain proper airflow once
the processor and heatsink are installed. All cables (for floppy
drive, hard drive, CD-ROM, etc.) must be routed clear of the
processor and its airspace. Otherwise, the processor will
overheat subsequently damaging the processor and the system
board.
2.3.1 Installing the Processor
1. Position the URM located at each end of Slot 1 into its upright
position.

processor down firmly, with even pressure on both sides of the
top, until it is completely seated. Push the latches located on the
top sides of the processor outward until they click into place in
the URM.
SECC2 or SEPP processor:
Position the SECC2 or SEPP processor above Slot 1 with the
