FEATURES
Specifications
The motherboard is designed with the Intel 82443BX CI chipset which is
developed by Intel Corporation to fully support the entium II rocessor
CI/ISA system. The Intel 82440BX CI chipset provides increased
integration and improved performance designs. The chipset provides an
integrated IDE controller with two high performance IDE interfaces for up
to four IDE devices (hard devices, CD-ROM device, etc). The Super I/O
controller provides the standard C I/O function: floppy interface, two
16Byte FIFO serial ports and E /EC capable parallel port. Care must
be taken when inserting memory modules, inserting C U or even plugging
CI /AG card into associated slots to avoid damaging any circuits or
sockets on board. A cooling fan is strongly recommended. The
motherboard supports minimum of 8MB of system memory and a
maximum of 384MB SDRAM. The motherboard provides three 168-pin
DIMM. The board also supports onboard two CI IDE connectors, and
detects the IDE hard disk type by the BIOS utility which is automatic. The
system also supports Award lug & lay BIOS for the ISA and CI cards.

FEATURES
ACP Ready - AC I (Advanced Configuration and ower Interface) is
also implemented on this motherboards. AC I provide more Energy
Saving Features for the future operating systems (OS) supporting OS
Direct ower Management (D M) functionality. With these features
implemented in the OS, Cs can be ready around the clock everyday,
yet satisfy all the energy saving standards. To fully utilize the benefits
of AC I, an AC I-supported OS such as in the next release of
Windows 95/98 must be used.
PC '97 Compliant - Both the BIOS and hardware levels of smart
series of motherboards meet C '97 compliance. The C 97
requirements for systems and components are based on the following
high-level goals: Support for lug and lay compatibility and power
management for configuring and managing all system components,
and 32-bit device drivers and installation procedures for both Windows
95/98 and Windows NT.
Temperature Monitoring and Alert - To prevent system overheat
and system damage, there are heat sensors to monitor the C U and
system temperatures to warn of damaging temperatures.
Voltage Monitoring and Alert - System voltage levels are monitored
to ensure stable current to critical motherboard components. Voltage
specifications are more critical for future processors, so monitoring is
necessary to ensure proper system configuration and management.
Modem Ring On - This allows a computer to be turned on remotely
through an external modem. With this benefit on-hand, any user can
access vital information from their computer from anywhere in the
world. But sometimes, the external MODEM just power ON/OFF,
the pulse will be taken as the Ring in signal, which will make the
machine power up. User needs to pay more attention about this
symptom.
OAP C 82093AA - Use the ntel 82093AA I/O Advanced
rogrammable Interrupt Controller (IOA IC) to provide multi-processor
interrupt management and incorporates both static and dynamic
symmetric interrupt distribution across all processors
Wake ON LAN - This main board implements a LAN-Wake U
connector, to use LAN Wake-up function, user need a network card
that supports this feature. In addition, user also needs to install
network management software, such as LDCM. The connector will
receive a wakeup packet or signal from LAN Card to power up the
system.

WARNING!
Computer motherboards, baseboards and components, such as SCSI
cards, contain very delicate Integrated Circuit (IC) chips. To protect
them against damage from static electricity, you should follow some
precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer
components. If you do not have one, touch both of your hands to
a safely grounded object or to a metal object, such as the power
supply case.
3. Hold components by the edges and try not to touch the IC chips,
leads or connectors, or other components.
4. lace components on a grounded antistatic pad or on the bag
that came with the component whenever the components are
separated from the system.
III-1 Jumpers Setting
1 2 3 1 – 2 Normal
2 – 3 Clear
CMOS Clearing
CMOS Clear, which is a safety hook if you forget the password.
1. After you have turned off your computer, clear the CMOS memory by
momentarily shorting pins 2-3, for a few seconds. Then restore it to the
initial 1-2 jumper setting in order to recover and retain the default settings.
Reset your computer now.
2. If you found that the system Date and Time doesn’t work and the
machine always appear the CMOS data error message, please check this
jumper to correct this problem.

-2 nstall System Memory Modules
This motherboard support 4 slots for 168-pin 3.3V Non-buffered DIMM
modules, providing support for up to 1GB of main memory using DIMM
modules from 8MB to 256MB. For 66MHz host bus C Us, please use 12ns
or faster DIMM modules. For 100MHz host bus C Us, please use 8ns or
faster DIMM modules. The following is the example to install the system
SDRAM memory module combination: if you have two DIMM Modules, you
has better install them into DIMM Slot 1 & Slot 2 with the Max possible
memory size up to 512MB ( 256 + 256 ) if the 256MB DIMM module is
available.
Note: t is highly recommended to use the PC-100 Spec. D MM module

The DIMM types supported SDRAM
(Synchronous DRAM). The following is the
summary:
Single side:
1Mx64 (8MB), 2Mx64 (16MB), 4Mx64
(32MB), 8Mx64 (64MB), 16Mx64 (128MB)
Double side:
1Mx64x2 (16MB), 2Mx64x2 (32MB),
4Mx64x2 (64MB), 8Mx64x2 (128MB).
Total Memory Size:
There is no jumper setting required for the
memory size or type. It is automatically
detected by the system BIOS, and the
total memory size is to add them together.
