Introduction to ASUS Smart Series motherboards
Performance
•SDRAM Optimized Performance -ASUS smart series of motherboards support 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.
•Concurrent PCI - Concurrent PCI allows multiple PCI transfers from PCI master busses to memory to CPU.
•ACPI Ready - ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series of motherboards. ACPI provide more Energy Saving Features for the future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock everyday, yet satisfy all the energy saving standards. To fully utilize the benefits of ACPI, an ACPIsupported 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.
Intelligence: (with optional Hardware/Thermal Monitor only)
•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.
II. FEATURES (Smart Series)
ASUS P2E-B User’s Manual |

FEATURES .II Series) (TX97
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 -Today’s operating systems such as Windows 95, Windows 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 (requires ATX power supply) -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 ATX power supply and 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 - 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.

III. INSTALLATION
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 connection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our mother-

with three pins. The jumpers will also be shown graphically such as |
|

||||
|
||||||
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 jump- |
||||
|
||||||
|
||||||
ers 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 diagramed.
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 space bar) 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 are not using the proper 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'sInternal 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. Two sockets are available for 3.3Volt (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.
Install memory in any combination as follows:

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.
