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 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:
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 (Synchronous 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.
1. Pull the tabs which are at the ends of the socket to the side.
2. Position the DIMM 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 DIMM in place.
Display Cache (PW35-E and PW35-D only)
The PW35-E and PW35-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 performance.

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.
