Introduction to ASUS Smart Series motherboards
Performance
•SDRAM Optimized Performance: ASUS smart series of motherboards sup-
port the new generation memory, Synchronous Dynamic Random Access
Memory (SDRAM), which increases the data transfer rate from 264MB/s max
using EDO memory to 528MB/s max using SDRAM.
•Double the IDE Transfer Speed: ASUS smart series of motherboards with
Intel chipsets improves IDE transfer rate using Bus Master UltraDMA/33 IDE
which can handle data transfer up to 33MB/s. The best of all is that this new
technology is compatible with existing ATA-2 IDE specs so there is no need to
upgrade current hard drives or cables.
•ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-
mented on all ASUS smart series of motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (OSPM) functionality . W ith these features implemented in the OS,
PCs can be ready around the clock, yet satisfy all the energy saving standards.
To fully utilize the benefits of ACPI, an ACPI-supported OS such as in the next
release of Windows 95 must be used.
•PC ’97 Compliant: Both the BIOS and hardware levels of ASUS smart series
of motherboards meet PC ’97 compliancy. The new PC ‘97 requirements for
systems and components are based on the following high-level goals: Support
for Plug and Play compatibility and power management for configuring and
managing all system components, and 32-bit device drivers and installation procedures for both Windows 95 and Windows NT.
•Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU fan and system fans can be monitored for RPM and failure.
Each fan can be set for its normal RPM range and alarm thresholds.
•Temperature Monitoring and Alert: To prevent system overheat and system
damage, there are heat sensors to monitor the CPU (the Pentium II processor
requires a special heatsink with a thermal sensor) and system temperatures to
warn of damaging temperatures.
ASUS P2E-M User’s Manual9
II. FEATURES
Smart Series
II. FEATURES
•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.
•System Resources Alert: T oday’ s operating systems such as W indows 95, W in-
dows NT , and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource monitor will warn the user before the system resources are used up to prevent possible application crashes. Suggestions will give the user information on managing their limited resources more efficiently.
•Auto Fan Off: The system fans will power off automatically even in sleep
mode. This function reduces both energy consumption and system noise, and
is a important feature to implement silent PC systems.
•Dual Function Power Button: The system can be in one of two states, one is
Sleep mode and the other is the Soft-Off mode. Pushing the power button for
less than 4 seconds places the system into Sleep mode. When the power button
is pressed for more than 4 seconds, it enters the Soft-Off mode.
•Remote Ring On (requires external modem): 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!
•Message LED (requires ACPI OS support): Chassis LEDs now act as information providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful information to the user.
•Keyboard Power Up: Keyboard Power Up can be enabled or disabled to allow
the computer to be powered on by pressing the space bar on the keyboard.

Installation Steps
Before using your computer, you must complete the following steps:
1.Set Jumpers on the Motherboard
2.Install System Memory Modules
3.Install the Central Processing Unit (CPU)
4.Install Expansion Cards
5.Connect Ribbon Cables, Cabinet Wires, and Power Supply
6.Setup the BIOS Software
1. Jumpers
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See motherboard layout for locations of jumpers. The
jumper settings will be described numerically, such as [----], [1-2], [2-3] for no con-
Jumpers
nection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our mother-
PIN 1
boards is always on top
keyboard connector away from yourself. A “1” is written besides pin 1 on jumpers
with three pins. The jumpers will also be shown graphically such as to connect
pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as
for Short (On) and for Open (Off). For manufacturing simplicity, the jumpers may be sharing pins from other groups. Use the diagrams in this manual instead of
following the pin layout on the board. Settings with two jumper numbers require that
both jumpers be moved together. To connect the pins, simply place a plastic jumper
cap over the two pins as diagrammed.
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.Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

2.Keyboard Power Up (KBPWR)
This allows you to disable or enable the keyboard power up function. Set this
jumper to Enable if you wish to use your keyboard (by pressing the spacebar) to
power up your computer. This feature requires an ATX power supply that can
supply at least 300mAmp on the +5VSB lead. The default is set to Disable
because not all computers have the appropriate ATX power supply. Your computer will not power on if you set this to Enable and if you do not have the right
ATX power supply.

3.CPU External (BUS) Frequency Selection (FS0, FS1, FS2)
These jumpers tell the clock generator what frequency to send to the CPU. These
allow the selection of the CPU’ s External frequency (or BUS Clock). The BUS Clock
times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
4.CPU to BUS Frequency Ratio (BF0, BF1, BF2, BF3)
These jumpers set the frequency ratio between the Internal frequency of the CPU
and the External frequency (called the BUS Clock) within the CPU. These must
be set together with the above jumpers CPU External (BUS) Frequency Selection.

2. System Memory (DIMM)
Only Dual Inline Memory Modules (DIMM) can be used with this motherboard.
T wo sockets are available for 3.3V olt (power level) Unbuffered Synchronous DRAMs
(SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB. One side (with memory
chips) of the DIMM module takes up one Row on the motherboard.
Error Checking and Correction (ECC) feature is not supported on this motherboard.
ECC DIMM will work on this motherboard minus the ECC feature.
IMPORTANT: Memory speed setup is required through "Auto Configuration" in
BIOS Chipset Setup of the BIOS SOFTWARE.
WARNING: Memory modules must have 18 chips or less. Memory modules
with more that 18 chips will cause unstable operation.

III. INSTALLATION
Non-ECC SDRAM DIMM (8 chips)
General DIMM Notes: (not true for all memory modules)
• Four possible memory chips are available: EDO or SDRAM with and without ECC.
• SDRAM chips are generally thinner with higher pin density than EDO chips.
• BIOS shows EDO or SDRAM memory on bootup screen.
• 8 chip/side modules do not support ECC, only 9 chip/side modules support ECC.
• Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.

DIMM Memory Installation
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation as shown. DIMM
modules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMM modules have the same pin contact on both sides.
