2.1.2 Specifications–Optional Components

The following onboard components are optional at the time of purchase:

• Onboard Audio: C-Media Audio Chip CMI8738 supporting the latest PCI 6

channel and HRTF 3D Audio sound circuitry. A software package helps setup
the multi-channel PC sound system.

®

• Promise

chip supports the ATA-100 protocol and Ultra DMA/100 data transfer speeds.
The chip also delivers reliable redundancy and stable performance to RAID
levels 0 or 1. Data “striping,” or RAID 0, improves speed performance as
I/Otasks are spread between two hard disk drives. Data “mirroring,” or RAID 1,
improves system fault tolerance as the protocol optimizes two identical hard
disks to write data to each other.

2.1.3 Performance

• UltraPerformance: Onboard IDE Bus Master controller with two connectors that

support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/
66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced
IDE devices:DVD-ROM, CD-ROM, CD-R/RW, LS-120, and T ape Backup drives.

chip: Available on the TUSL2, the Promise IDE controller

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory and processor.

• SDRAM Optimized Performance: This motherboard supports PC133-com-

pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 1066MB/s max.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for operating systems (OS) supporting OS Direct Power Man­agement (OSPM). W ith these features implemented in the OS, PCs can be ready
around the clock, yet satisfy all the energy saving standards. To gain all the
benefits, an ACPI-supported OS, such as Windows 98/2000/ME is required.

• Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do
not have to wait for a long time for system bootup.

• New Compliancy: Both the BIOS and hardware levels of the motherboard meet

the stringent requirements for PC 99 certification. The new PC 99 requirements
for systems and components are based on high-level goals: support for Plug and
Play compatibility and power management for managing all system compo­nents, and 32-bit device drivers and installation procedures for W indows 95/98/
NT. Color-coded connectors and descriptive icons make identification easy.

2.1.4 Intelligence

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU, power supply, and system fans can be monitored for RPM
and failure. All the fans are set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-

age, this motherboard supports processor thermal sensing and auto-protection.

• 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 ME,

Windows 2000, and OS/2, require much more memory and hard drive space to
present user interfaces and run large applications. The onboard hardware ASUS
ASIC in conjunction with either the bundled ASUS PC Probe or Intel LDCM
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.

• 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 (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

• Remote Ring On (requires modem): This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on-hand, users
can access any information from their computers from anywhere in the world.

• Message LED (requires ACPI OS support): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine if a message has been received from a fax/modem. A simple glimpse
provides useful information to the user. This function requires ACPI OS and
driver support.

Intelligence

2. FEATURES

• Peripheral Power Up: Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

3.3 Hardware Setup Procedure

Before using your computer, you must complete the following steps:

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

WARNING! Computer motherboards and expansion 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.

5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.

WARNING! Make sure that you unplug your power supply when adding or

removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components. The onboard LED when
lit acts as a reminder that the system is in suspend or soft-off mode and not
powered OFF.

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM). One side (with memory chips) of the DIMM takes up one
row on the motherboard.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1

Total System Memory (Max 512MB) =

NOTE: Make sure the total installed memory does not exceeds 512MB. Otherwise,

the system may hang during startup.

3.5.1 General DIMM Notes

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32,

64, 128, 256, 512MB.

NOTE: For PC133 SDRAM to run at 133MHz, the system CPU bus must also
operate at that speed.

cause severe damage to both your motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).

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 shown. DRAM SIMM
modules have the same pin contacts on both sides. SDRAM DIMMs have different
pin contacts on each side and therefore have a higher pin density.

1. Locate the Socket 370 and open it by pulling
the lever gently sideways away from the socket.
Then lift the lever upwards. The socket lever
must be fully opened (90 to 100 degrees).

2. Insert the CPU with the correct orientation. The
gold arrow of the CPU must be oriented
toward the outer corner of the socket base
nearest to the tip of the lever handle.

CAUTION! The CPU fits in one orientation

and should drop easily into place. Do not force
the CPU into the socket to avoid bending the

pins. If the CPU does not fit, check its
alignment and look for bent pins.

3. Once completely inserted, press the CPU firmly and close the socket lever until it
snaps into its locked position.

4. Install an Intel fan heatsink. The heatsink should entirely cover the CPU. Care­fully attach the heatsink locking brace to the plastic clips on the socket base. W ith
the added weight of the CPU fan and heatsink locking brace, no extra force is
required to keep the CPU in place. Connect the CPU fan cable to the fan connec­tor (See 3.1 Motherboard Layout / 3.8 Connectors).

CAUTION! Take care not to scrape the motherboard surface when mounting a

clamp-style processor fan, or else damage may occur . When mounting a heatsink
onto your CPU, make sure that exposed CPU capacitors do not touch the
heatsink, or else damage may occur! Refer to heatsink/CPU documentation.
NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency

multiple setting is available only on unlocked processors) for your Socket 370
processor or else boot-up may not be possible. Socket 370 processors provide
internal thermal sensing: a socket mounted thermal resistor is not needed.

3.7.2 Assigning IRQs for Expansion Cards

Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu­sively assigned to one use. In a standard design, there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has PCI audio onboard, an additional IRQ will be used. If your moth-

erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

(40-1 pin PRIMARY IDE and SECONDARY IDE)
(40-1 pin PRIMARY ATAIDE and SECONDARY ATAIDE)

These connectors support the IDE hard disk ribbon cables supplied with
the motherboard. Connect the cable’s blue connector to the motherboard’s
primary IDE connector (recommended) or the secondary IDE connector . Then
connect the opposite end of the cable to your UltraDMA/100/66 device (hard
disk drive). A second slave hard disk may be attached to the intermediate
connector on the cable. If a second hard disk drive is connected, you may reset
its jumper to Slave mode. Refer to your hard disk documentation for the jumper
settings. It is recommended that non-UltraDMA/100/66 devices be connected
to the secondary IDE connector. BIOS now supports specific device bootup
(see 4.6 Boot Menu.) If you have more than two UltraDMA100/66 devices, you
will need to purchase another UltraDMA100/66 cable. (Pin 20 is removed to

prevent inserting in the wrong orientation when using ribbon cables.)

The TUSL2 motherboard is supplied with two extra onboard IDE connectors:
one Primary ATAIDE1 and one Secondary ATAIDE2. You can use them to
setup the RAID 0 or 1 arrays and to support extra IDE devices. A total of eight
hard-disks, two on each IDE connector, can be connected to the TUSL2, but
only two can function in a RAID array. See 5.4 Software Setup for more
information about setting up a RAID array.

TIP: For high-performance and RAID 0 or 1 set ups, always setup two hard
disks with two separate ribbon cables, one for the primary IDE connector and
another for the secondary IDE connector. Usually, both disks may be set to the
Master settings. Also, you may install one operating system on an IDE drive
and another on a SCSI drive and select the boot disk through BIOS. (See 4.6
Boot Menu.)

NOTE: UltraDMA/100 is backward compatible with DMA/66 an d DMA/33
and with all with existing DMA devices and systems, so there is no need to
upgrade current EIDE/IDE drives and host systems.

IMPORTANT: UltraDMA66 and UltraDMA100 IDE devices require a 40-pin

80-conductor cable and RAID arrays only operate with such cables.

Connectors (3 pins)

These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan’s plug to the board taking into consid-
eration the polarity of the connector.

NOTE: The “Rotation” signal is to be used only by a specially designed fan with
rotation signal. The Rotations per Minute (RPM) can be read directly from the
ASUS iPanel or monitored using a utility such as ASUS PC Probe (or Intel LDCM.)

4.1 Managing and Updating Your BIOS

4.1.1 Upon First Use of the Computer System

It is recommended that you save a copy of the original motherboard BIOS
along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable
floppy disk in case you need to reinstall the BIOS later . AFLASH.EXE is a
Flash Memory W riter utility that updates the BIOS by uploading a new BIOS
file to the programmable flash ROM on the motherboard. This file works
only in DOS mode. To determine the BIOS version of your motherboard,
check the last four numbers of the code displayed on the upper left-hand
corner of your screen during bootup. Larger numbers represent a newer BIOS
file.

1. Type FORMAT A:/S at the DOS prompt to create a bootable system
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the
disk.

2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-
ROM drive) to copy AFLASH.EXE to the just created boot disk.

NOTE: AFLASH works only in DOS mode. It will not work with DOS
prompt in Windows and will not work with certain memory drivers that
may be loaded when you boot from your hard drive. It is recommended
that you reboot using a floppy.

3. Reboot your computer from the floppy disk. NOTE: BIOS setup must
specify “Floppy” as the first item in the boot sequence.

4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.

4. BIOS SETUP

IMPORTANT! If “unknown” is displayed after Flash Memory:, the memory

chip is either not programmable or is not supported by the ACPI BIOS and
therefore, cannot be programmed by the Flash Memory Writer utility.

4.2 BIOS Setup Program

This motherboard supports a programmable EEPROM that can be updated using
the provided utility as described in 4.1 Managing and Updating Your BIOS.

The utility is used if you are installing a motherboard, reconfiguring your system,
or prompted to “Run Setup”. This section describes how to configure your system
using this utility.

Even if you are not prompted to use the Setup program, at some time in the future
you may want to change the configuration of your computer. For example, you
may want to enable the Security Password Feature or make changes to the power
management settings. It will then be necessary to reconfigure your system using
the BIOS Setup program so that the computer can recognize these changes and
record them in the CMOS RAM of the EEPROM.

The EEPROM on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. This
appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup
utility . If you are a little bit late in pressing the mentioned key, POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by press­ing the Reset button on the system chassis. You can also restart by turning the
system off and then back on again. But do so only if the first two methods fail.

The Setup program has been designed to make it as easy to use as possible. It is a
menu-driven program, which means you can scroll through the various sub-menus
and make your selections among the predetermined choices.

To access the BIOS Setup program, press the <Delete> key after
the computer has run through its POST.

5.4 Using the Promise

The Promise® chip, PDC20265R, onboard the TUSL2, offers a high performance
Redundant Array of Independent Disks (RAID) configuration that supports only
UltraATA-100/66/33, EIDE or FastATA-2 hard disks. After connecting two hard
disks to the motherboard, activating either RAID 0 or 1 function is easily configured
through the FastTrak100™ “Lite” firmware BIOS during boot up. In addition, the
support CD allows you to install system drivers according to the Operating System
(OS) on your computer. Read through this section in its entirety before setting up
your RAID system.

RAID 0 is also known as “data striping.” Striping optimizes two identical hard disk
drives to read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive, and at a sustained data transfer rate double that of a
single disk alone. The main advantage of a RAID 0 array is to improve the Speed
Performance of data access and storage. With FAT32 and NTFS partitioning, the
array will be addressed as one large volume.

Chip for RAID 0 or 1

5. S/W SETUP

RAID

RAID 1 is also known as “data mirroring.” Mirroring optimizes two identical hard
disk drives to copy all data from one hard disk drive to the other and vice versa. As
new data is written, it is duplicated onto both disks using a parallel write process.
The main advantage of RAID 1 is that it greatly increases Fault Tolerance of the
entire system, especially if each hard disk is connected separately to both ATA-100
IDE channels available on the TUSL2. Should one hard disk suffer mechanical
trouble, all system data will be preserved on the other drive.

IMPORTANT! Before setting up your new RAID array, verify the status of your

hard disks. It is possible to use a pre-existing hard disk for RAID 0 only if the data
is backed up before configuring the array as all hard disk data will be lost during the
set up. RAID 0 requires at least two hard disks for optimal results. It is possible to
use a pre-existing hard disk for RAID 1 to duplicate the source data; also, RAID 1

can set up two or more new disks. The Promise
and the FastBuild™ Utility on the TUSL2 permit only two disks to be configured in
RAID 0 or RAID 1 pairs and combinations; a third, “hot” spare hard disk may be
used to support a RAID 1 array; (see the end of this section for more detail). For
optimal performance, install only identical hard disks of the same model and storage
capacity. Use only Ultra ATA-100/66 compatible IDE cables and connectors. The

simultaneously. RAID 1 arrays can use a pre-existing hard disk along with a blank
hard disk, or two new hard disks.

1. Install the first and second hard disk into the hard disk bays of your system.

Connect each hard disk drive with a separate UltraDMA/100 cable, one to the
Primary AT A IDE1 connector, and the other to the Secondary ATA IDE2 connector
onboard the TUSL2.

2. Connect the power cables to the hard disks.

3. Ensure that the AT A/100 / RAID 0/1 jumper 3 is reset from the default to [1-2].

8. If duplicating an original Operating System to another new hard disk, the system
will start up automatically . If creating a brand new RAID 1 array only, it will be
necessary to intstall a new OS. Reboot with a rescue floppy disk to format the
hard disks with the FDISK command and then install the OS from a CD;
alternatively, with a bootable OS CD, install the new OS automatically.

NOTES for Troubleshooting Array Set Ups:

Always use two separate UltraDMA/100 cables for linking each of two hard disks to
the Primary ATA-100 and the Secondary ATA-100 connectors. Usually, a two disk
array will set up properly if both sets of hard disk jumpers are set to Master. However,
it may be necessary to reset the jumpers on each of the hard disks; in such cases, try

Master for the Source disk, and Master/Slave or Slave for the Target disk. Also, if a
Source hard disk lar ger than the T arget disk is selected, the FastBuild™ utility suggests

using a larger or equal size disk for the T arget instead. During reboots after configuring
a RAID array, the IDE scan process determines if the system is working okay.
Normally the FastTrak100™ “Lite” BIOS displays system status as Functional
after rebooting the new RAID array . However, two warnings may appear: Critical
indicates that one or more drives in the array are not functional, or are disconnected.
In this case, enter the FastBuild™ Utitility to diagnose the problem and replace the
faulty drive. The second warning, Offline, indicates that one hard disk in a striped
(RAID 0) array has failed, cannot be detected, or has become disconnected. In this
case, adjust or replace the hard disk if necessary and rebuild data from a back-up
source.

5.4.6 Alternative Set Ups and Other Details

Hot Spares

A hot spare hard disk may be installed to support a RAID 1 array. This spare hard
disk must share one of the Ultra-DMA/100 cables attached to either of the hard
disks active in a RAID 1 array . In the event of a failure of either active hard disk in
the array , the “Lite” BIOS detects the hot spare and automatically rebuilds the mirrored
data from the functional hard disk. The FastBuild Utility will report a warning
message after such a hard disk failure; it may indicate that the good hard disk and
the hot spare are connected to the same cable, so then it will be necessary to transfer
the hot spare to the other cable and reboot again.

5. S/W SETUP

RAID

Use Both ATA-100 Connectors

Optimal performance for RAID 0 and 1 arrays require that each hard disk be connected
to separate IDE channels; the first hard disk should be connected to the Primary
AT A-100 connector and the second hard disk, to the Secondary ATA-100 connector .

Adding Extra Hard Disks

The TUSL2 is supplied with two additional Primary IDE and Secondary IDE
connectors. Only two hard disks connected to the Primary and Secondary ATA-100
IDE connectors can function in a RAID 0 or RAID 1 array . Extra hard disks may be
connected to the system using the onboard IDE connectors, but such disks cannot be
configured in a RAID array . In principle, up to eight hard disks or other IDE devices
may connect to the TUSL2. Whether an array is set up or not, all hard disks connected
to the TUSL2 will function at the ATA-100 protocol.

Use ATA-100, High-RPM Hard Disks with Identical Storage Capacity

The fastest available hard disks should be used in the RAID 0 array to maximize
performance. Slower hard disks may be used; however, the RAID 0 array can only
double the speed of particular hard disks. Since you can achieve better performance
with a single ATA-100 hard disk than with two ATA-33 disks in a RAID 0 array , it is
more effective to install two AT A-100 or AT A-66 high-RPM hard disks for an array.
Hard disks used for both RAID 0 and 1 arrays should always have the same storage
capacity because the RAID protocol automatically formats both disks to use only up
to the maximum write space available on the smaller of two hard disks with different
memory capacities..

6.1 Winbond Smart Manager

The Winbond Smart Manager is a clever utility that helps secure the PC
with a Read2-IN-01 Smart Card Reader (see page 7) and a smart card
containing a mini-chip insert, like a GSM cell phone SIM card. Once a
smart card reader is configured, set up the Smart Manager software utility
for “boot up” or “always on” system security.

6.1.1 Setting Up Smart Manager

Connect the smart card reader to the TUSL2; (refer to Section 3.8.23 in
Hardware Setup for the connector location.) Boot up the PC and enter

BIOS (press <del>) to change the configuration to accept smart card
hardware: in the Advanced BIOS menu select the I/O Device Configuration
sub-menu, go to UART2 and select Smart Card Read, save and exit.

The auto-installer implements all of
the drivers, base components and
displays the Winbond Smart Manager
program groups. Restart. Windows
should auto-detect the smart card
reader and install its system drivers.

NOTE: Do not install system components or Winbond applications unless you

install a smart card reader, (see page 7). Smart card system software
components support various types of smart card applications; all system com­ponents are compatible with Windows 98, ME and 2000. However, the

Windbond Smart Manager application is readily compatible only with
Windows 98 and ME.

6.1.3 Smart Manager Modes

Return to the Windbond Smart Manager icon on the bottom right hand
corner of the Windows screen. Select the Logon Card Check Mode to
choose the security mode. Three basic modes are available:

1. Disable Check renders the Smart Manager security system inoperative.

2. Boot Check enables the Smart Manager security system for start up.
The user must insert the smart card into the reader during start up in order to
complete the Windows boot up process. In this mode, the user may
remove the smart card and continue to use the PC after the start cycle is
complete. If no smart card, or the wrong one, is inserted during boot up, the
PC displays the Smart Manager Protection Screen:

6. SOFTWARE REFERENCE

Whenever the Smart Manager
Protection Screen is displayed,
the computer is secured and
impenetrable.

3. Always Check configures the Smart Manager to require that the user
insert the smart card during start up; then, if the card is removed at any time
during the operation of the PC, the Smart Manager protection screen will
automatically pop up and the PC is secure until the card is reinserted.

File Protect Check Mode: This is a sub-program used to encrypt and
decode individual files stored in the system using a smart card as a key.

NOTE: Do take care not to lose your smart card or you may not be able

to restart the PC or decode encrypted files. Test each new smart card to
ensure that it is completely compatible with the card reader; the Read2-
In-01 Smart Card Reader is designed only to read cards with the
standard PC/SC mini-chip configuration.
