About the Soft Touch Power Button
In an ATX based system, the new soft touch power button
replaces the main power switch that turns your system on and
off. From an OFF state, you can switch the system ON by
simply pressing the power button. From an ON state, the system
can be turned OFF by pressing and holding the power button
for four (4) seconds OR shut down instantly. The functions of
the power button can also be altered in the Power Management
section in the BIOS setup.
C Universal Serial Bus (USB) / Lan (Optional)
Connector
The Mainboard provides Two 4-pin Universal Serial Bus
(USB) connectors. USB is a new interface standard for adding
external Plug-and-Play (PnP) devices to the computer system.
Peripherals that support USB PnP capabilities can operate at up
to a 12Mb/sec data transfer rate. Eventually, all external devices
connected to your computer will be standardized to USB.
Mainboard User's ManualPage 44
Your mainboard may come with an optional onboard LAN func-
tion. It utilizes the Intel 82562ET Physical Layer Interface,
which is IEEE 10BASE-T and 100BASE-TX compliant. If your
mainboard does come with an onboard LAN function, make sure
it is enabled in the BIOS setting under “Integrated Peripherals” in
order to use it. If you rather install and use the LAN function on
the CNR card, make sure you disable the onboard LAN function
and select “EXT. CNR” in the BIOS setting. The reason being
that they both share the same LAN controller on the ICH2 chip.
Only one physical layer interface can uses the LAN controller at
a time, otherwise conflict will occur.
c Universal Serial Bus (USB) Header
Connect this header to the optional USB extension cable for
a USB port.
D Serial (COM1 & 2) Headers
The Mainboard provides two 9-pins serail port headers.
E Infrared (IR) Header
The Mainboard provides a 5-pin header interface, IR
for connection to a Hewlett Packard HSDSL-1000 compatible
infrared (IrDA) transmitter/receiver. Connect IR to the front panel
I/O IrDA connector provided with your system. Once the module
is connected to the front panel I/O IrDA connector, Serial port
2 can be re-directed to the IrDA module. When configured for
IrDA, the user can transfer files to or from portable devices such
as laptops, PDA’s, mobile phone and printers using application
software such as LapLink. The IrDA specification provides for
data transfers at 115 kbps from a distance of 1-meter. Support
for Consumer infrared (ASK-IR) is also included. Please refer to
your IR equipment for more detailed information.

F Memory Module Sockets
The Mainboard provides 168 pin standard DIMM sockets for
installation of 3.3V unbuffered Single or Double Bank SDRAM
modules.
G Parallel Port Connector
The ATX Mainboard provides a parallel port connector. Based
on the ATX standard, a 25-pin parallel port is now built on
the mainboard back panel. This design makes the mainboard
installation easier. The parallel port can be BIOS configured
into standard (SPP) mode, Enhanced Parallel Port (EPP) mode,
and a high speed Extended Capabilities Port (ECP) mode. EPP
Mode requires a driver provided by the peripheral manufacturer
in order to operate properly.
H Accelerated Graphics Port [AGP] Connector
The Mainboard provides an AGP slot compatible with the
Accelerated Graphics Port specification. AGP compliant video
cards offer a much higher throughput than equivalent PCI bus
video cards. PCI currently only supports a 33MHz bandwidth,
and can transport at peak rates up to 133MB/s over its 32 bit
data bus. AGP operates at a 66MHz bandwidth which enables
a peak rate of 266MB/s in what is known as 'X1' mode. 'X2'
mode has a peak rate of 532MB/S. 'X4' mode has a peak rate
as high as 1.06GB/S. However, the 845 chipset only support
the 1.5V AGP under 4X mode.

I LITHIUM BATTERY
A 3V, CR2032, Lithium battery is installed on the on-board
battery socket. This battery is used to supply the CMOS
RAM backup power during system powered-off. Danger of
explosion if battery is incorrectly replaced. Therefore, if you
have any difficulties, please consult the technical personnel.
J PCI Add-In Board Connector
The Mainboard provides 6 PCI Connector for the PCI cards.
M Front Panel Function Connector
The Mainboard integrates all system front panel functions into
a single on-board connector. These include connections for the
following features:
Function Connector Pin-Out Label
System Reset RESET
Power LED / Keylock PW-LED
Hard Drive Activity LED HD_ LED
Soft-Touch Button Power On/Off PW-BN
External Power Saving Control (optional) EXTSMI
Suspend LED Sus-Led

Glossary
N Flash BIOS
The Mainboard Flash BIOS provides users with more flexibility
in upgrading their mainboards. The flash BIOS can be easily
reprogrammed via software.
O Floppy Drive Header
The Mainboard provides a 34-pin header that supports the
included floppy drive ribbon cable. After connecting the single
end to the on-board “FLOPPY” header, connect the remaining
plugs on the other end of the cable to the corresponding
floppy drives.
P IDE Device Headers
The Mainboard provides two independent bus-mastering PCI
IDE interfaces capable of supporting up to Mode 4 and Ultra
DMA-33/66/100 devices. The system BIOS supports automatic
detection of the IDE device data transfer rate and translation
between different kinds of device modes such as Logical Block
Addressing (LBA), Extended Cylinder Sector Head (ECSH)
translation modes and ATAPI (e.g., CD-ROM) devices on both
IDE interfaces.
The two on-board IDE headers support the provided 80-pin IDE
hard disk ribbon cables. If you install two hard disks and/or
CD-Rom drives onto the same cable, you must configure the
two drives by setting their IDE master/slave jumpers according
to the documentation for those devices.
You may also connect the two hard disk drives so that both
become Masters, using one ribbon cable on the primary IDE
header and one on the secondary IDE header.

Q WAKEUP-LINK Header
The Mainboard provides on WAKEUP-LINK header (WOL1)
used to connect an add-in Network Interface Card which has
Wakeup capability.
r "CNR" Add-in Board Connector
Communication & Networking Riser (CNR) is a new interface
standard for Networking or modem add-in card.
S CPU Socket
The Mainboard provides a 478-pin CPU Socket for Intel
Pentium 4 processor. The CPU should have a heatsink along
with a fan attached to it to prevent overheat. If a fan is not
present, a fan should be installed prior to turning the system
on.
Mainboard User's ManualPage 48
Glossary
T CPU & System Fan Headers
The recommended heatsink for the processor are those
with 12 Volt three-conductor fan that can be connected to the
fan connector on the mainboard. It provides +12 Volts DC for
the CPU cooling fan as follows:

CAUTION! Be sure that sufficient air circulation is available across the
processor’s heatsink by regularly checking that your CPU fan is
working. Without sufficient circulation, the processor could overheat
and damage both the processor and the mainboard. You may install
an auxiliary fan if necessary.
The SYSTEM FAN header is provided for optional cooling fans.

Introduce INSTANT ON function:
INSTANT ON is a Windows 98 ACPI sleep mode function. When
recovering from sleep mode, the system is able, in just a few
seconds, to retrieve the last “state” of the system before it went to
sleep and recover to that state. The “state” is stored in memory
(RAM) before the system goes to sleep. During sleep mode,
your system uses only enough energy to maintain critical
information and system functions, primarily the system state and
the ability to recognize various “wake up” triggers or signals,
respectively.
INSTANT ON function Installation
Please follow the steps to complete the INSTANT ON function
installation.
