the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.
External Modem Ring-on
The Modem Ring-on feature allows the system that is in the
Suspend mode or Soft Power Off mode to wake-up/power-on to
respond to incoming calls.

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.
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:
If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply must
support a minimum of ≥ 1A. A ≥ 720mA 5VSB power source is
sufficient if you are using only one or two of these functions.
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.
 If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply
must support a minimum of ≥ 1A. A ≥ 720mA 5VSB power
source is sufficient if you are using only one or two of these
functions.

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 Power
Management Setup 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:
If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply must
support a minimum of ≥ 1A. A ≥ 720mA 5VSB power source is
sufficient if you are using only one or two of these functions.

Hardware Installation
2.2 System Memory
The system board is
equipped with two 168-
pin DIMM (Dual In-line
Memory Module) sockets
that support unbuffered
PC-100 SDRAM DIMM.
PC SDRAM (Synchro-
nous Dynamic Random
Access Memory) is a
fast memory interface
technology that uses 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. This saves time
during transmission of data, subsequently increasing system
performance.
The onboard VGA shares 1MB of the system memory. This is fixed
regardless of the size of the system memory.
Aside from the 1MB shared memory, it also uses the Dynamic
Display Memory (DDM) technology. DDM freely changes in size
because graphics memory is allocated from the system memory
according to current needs.
Refer to chapter 1 for the type of memory supported by the
system board.
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.

2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of the
socket.
Display Cache (CW35-E and CW35-D only)
The CW35-E and
CW35-D system
boards are each
mounted with 2
SDRAMs that serve as
4MB display cache.The
presence of the display
cache will provide
better system perform-
ance.

2.3 Jumper Settings for Clearing CMOS Data
Jumper JP2
Clear CMOS Data
If you encounter the
following,
a) CMOS data becomes
corrupted.
b) You forgot the super visor
or user password.
c) You are unable to boot-
up the computer system
because the processors
clock/ratio was incorrectly
set in the BIOS.
you can reconfigure the system with the default values stored in the
ROM BIOS.
To load the default values stored in the ROM BIOS, please follow
the steps below.
1. Power-off the system.
2. Set JP2 pins 2 and 3 to On. Wait for a few seconds and set JP2
back to its default setting, pins 1 and 2 On.
3. Now power-on the system.
If your reason for clearing the CMOS data is due to incorrect
setting of the processors clock/ratio in the BIOS, please proceed
to step 4.
4. After powering-on the system, press <Del> to enter the BIOS
setup utility.
5. Select the CPU Frequency Control submenu and press <Enter>.
6. Set the CPU Clock/Spread Spectrum or CPU Ratio field to
its default setting or an appropriate bus clock or frequency ratio.

erals submenu of the BIOS
must be set accordingly. Refer
to chapter 3 for details.
Warning:
1. If JP5 was enabled with a password set in the KB Power
On Password field, and now you wish to disable the
keyboard password function, make sure to set the
Keyboard/Mouse Power On field to Disabled prior to
setting JP5 to disabled. You will not be able to boot up the
system if you fail to do so.
2. The power button will not function once a keyboard
