•ACPI Ready: Advanced Configuration and Power Interface (ACPI) is also
implementedon allASUSsmartseriesmotherboards.ACPIprovidesmoreEnergy
Saving Features for 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, yet satisfy all the energy saving standards.
To fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows
2000, must be used.
•NewCompliancy:Both the BIOS and hardware levels of the motherboard meet
the stringent requirements for SDG2.0 certification. The new SDG2.0
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 Windows NT/2000/XP. Color-coded connectors and
descriptive icons make identification easy as required by PC ‘99.

Intelligence
2.1.3 Intelligence
•Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU, power supply, and system fan speeds are monitored. All the
fans are set to normal RPM range and alarm thresholds.
•Temperature Monitoring and Alert: To prevent system overheat and system
damage,this motherboard supports processor thermalsensing and auto-protection.
•Voltage Monitoring andAlert: 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.
•Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by”(a.k.a. Suspend or Sleep) button or as the Soft-Off button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

through aninternal or external modem.With this benefiton-hand, users can access
any information from their computers from anywhere in the world.
•Server Management: The motherboard comes with an ASMC card connector
(supportsthe optionalASMC-LEandASMC-MEcards) that complieswith server
reliability, availability, and serviceability requirements. Remote management
response via remote diagnostics and troubleshooting still works even when the
operating system has frozen.

3.3 Hardware Setup Procedure
Complete the following steps before using your computer:
1. Check motherboard settings
2. Install memory modules
3. Install the Central Processing Unit (CPU)
4. Install a CPU terminator, if you installed only one CPU.
5. Install Expansion Cards
6. Connect ribbon cables, panel wires, and power supply cables
7. Configure the BIOS parameter settings
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any internal
component.
2. Use a grounded wrist strap or touch a safely grounded object, such as the
power supply case, before handling components to avoid damaging them
due to static electricity.
3. Hold components by the edges and do not touch the ICs on them.
4. Wheneveryou uninstall any component, placethe componentsonagrounded
antistatic pad or in the bag that came with the component.
5. Beforeyouinstallorremoveanycomponent,ensurethattheATXpower
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.
3.4 Jumper Settings
There is only one jumper on the motherboard. This jumper allows you to set the
speed for the PCI slots.

3. H/W SETUP
3.5 System Memory
This motherboard uses interleaved PC133 Dual Inline Memory Modules (DIMMs).
Six DIMM sockets are available for 3.3Volt (power level) registered Synchronous
Dynamic Random Access Memory (SDRAM) of 16MB, 32MB, 64MB, 128MB,
256MB, 512MB, or 1GB densities with Serial Presence Detect (SPD) and Error
Check and Correction (ECC).
The motherboard supports system memory of up to 6GB in a two-way interleaved
configuration.This configuration requires that you install identical DIMMs (exactly
the same type and size) in pairs. For example, if you installed a 512MB module into
DIMMA1, you must install the same type of 512MB module into DIMMB1. The
same rule applies to pairs DIMMA2/DIMMB2 and DIMMA3/DIMMB3.
The following table lists the DIMM socket pairs and the memory modules you can
install.

Total System Memory (Max. 6GB) =
IMPORTANT: The system chipset only supports 64Mbit, 128Mbit, and 256Mbit
“registered”SDRAMs with ECC. Make sure to use only the specified DIMM
types for smooth system operation.

18 ASUS TRL-DLS User’s Manual
3. HARDWARE SETUP
Insert a DIMM into the DIMM socket as shown. Because the number of pins are
different on either side of the breaks, the module only fits in one direction. SDRAM
DIMMs have different pin contacts on each side.
The notches on the DIMM shifts between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.
Useonly 3.3Volt “registered”SDRAMDIMMs.To determine the DIMM type, check
the notches on the DIMMs (see the figure below).
WARNING! Make sure that you unplug the power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both the motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).

3.6 Central Processing Unit (CPU)
The motherboard comes with a dual Socket 370 for Intel Pentium III Coppermine
(256KB L2 cache) and Tualatin (512KB L2 cache) CPUs running up to 1.53+GHz
with 133MHz Front Side Bus (FSB). The following illustration shows the location
of the CPU sockets on the motherboard, and the correct CPU and terminator
orientation.
Note in the illustration that the CPU and the terminator have marks (usually a notch
or a gold mark on one corner) to help you identify the proper orientation and enable
you to correctly install them. It is important that you match the marked corner of the
CPU and terminator with the corresponding corner on the socket so as not to damage
the CPU pins.

3.6.1 Installing the CPU and Terminator
Follow these steps to install a CPU.
1. Locate the ZIF socket on the motherboard.
2. Unlock the socket by pressing the lever
sideways then lifting it up to a 90°-100°
angle.
3. Position the CPU above the socket such
that its notched or marked corner matches
the socket corner near the end of the lever,
while making sure that the CPU is parallel
to the socket.
4. Carefully insert the CPU into the socket
until it fits in place.
CAUTION! The CPU fits only in one orientation. Do not force the CPU into the
socket to prevent bending the pins and damaging the CPU. If the CPU does not
fit completely, check its orientation or check for bent pins.
5. When the CPU is in place, press it firmly on the socket while you push down the
socket lever to secure the CPU. The lever clicks on the socket indicating that it
is locked.
6. Install a CPU heatsink. Refer to the documentation that came with the heatsink.
7. Install the CPU terminator the same way
as you would install a CPU. The figure on
the right shows an installed CPU
terminator.
CAUTION! DO NOT install a heatsink on the terminator! It will damage the
motherboard!
