3.4 Hardware Setup Procedures

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

1. Check motherboard settings

2. Install memory modules

3. Install the Central Processing Unit (CPU)

4. Install an expansion card

5. Connect ribbon cables, panel wires, and power supply

6. Setup the BIOS software

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 the power supply when adding or removing
system components. Failure to do so may severely damage the
motherboard, peripherals, and/or components. When lit, the onboard
LED indicates that the system is in suspend or soft-off mode, not
powered OFF.

ASUS Terminator Barebone System 41

3.5 Motherboard Settings

This motherboard does not have jumpers nor switches to configure.
However , there are two solder points onboard that allow you to clear
the RTC RAM when necessary.

1. Clear RTC RAM. This jumper allows you to clear the Real Time
Clock (RTC) RAM in CMOS. You can clear the CMOS memory
of date, time, and system setup parameters by erasing the CMOS
RTC RAM data. The RAM data in CMOS, that include system
setup information such as system passwords, is powered by the
onboard button cell battery.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the battery.

3. Short the jumper.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

3.6 System Memory

This motherboard uses only Dual Inline Memory Modules (DIMMs).
Two DIMM sockets are available for 3.3Volt (power level) unbuffered
Synchronous Dynamic Random Access Memory (SDRAM) of 16, 32,
64, 128, 256, or 512MB densities for a system memory configuration
of 32MB up to 1GB. One side (with memory chips) of the DIMM takes
up one row on the motherboard. This motherboard also supports NEC’s
Virtual Channel SDRAMs and Enhanced Memory System’s High-

speed DRAMs.

IMPORTANT

• Make sure to use SDRAMs that are compatible with the
current Intel PC133 SDRAM specifications.

• DO NOT attempt to mix registered SDRAMs with VCM
SDRAMs.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

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

Total System Memory (Max. 1GB) =

3.6.1 General DIMM Notes

• DIMMs that have more than 18 chips are not supported on this

motherboard.

• For the system CPU bus to operate 100MHz/133MHz, use only
PC100-/PC133-compliant DIMMs.

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

• SDRAM chips are generally thinner with higher pin density than
EDO (Extended Data Output) chips.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 32, 64,128, 256MB; double-sided come
in 64, 128, 256, 512MB.

44 Chapter 3: Motherboard Information

3.6.2 Memory Installation

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 3.4 Hardware Setup Procedure for more information).

Insert the module(s) into the DIMM sockets 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 and have a higher pin density than DRAM SIMMs.

Lock

TUSC 168-Pin DIMM Sockets

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the
DIMM type, check the notches on the DIMMs (see the figure below).

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.

ASUS Terminator Barebone System 45

3.7 Central Processing Unit (CPU)

The motherboard comes with a ZIF Socket to support CPUs as listed
on section 3.1.1 Specifications. The following illustration shows the
CPU socket location on the motherboard and the correct CPU
orientation.

Note in the illustration that CPUs 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 a CPU. It is important that you
match the marked corner of the CPU with the corresponding corner
on the socket so as not to damage the CPU pins.

The CPU picture above is for reference only. Usually, when you buy
a CPU, the heatsink and fan are already attached to the CPU. If a
heatsink and fan did not come with the package, make sure you
obtain one before installing the CPU.

WARNING!

Y ou must install the proper heatsink and fan to the CPU. Failure to do
so will cause the CPU to overheat and may damage both the CPU
and the motherboard. Install an auxillary fan, if necessary.

CAUTION!

Be careful not to scrape the motherboard when mounting/unmounting
a clamp-style processor fan to avoid damaging the motherboard.

46 Chapter 3: Motherboard Information

3.8 Expansion Cards

In the future, you may need to install expansion cards. The
motherboard has two PCI expansion slots to support PCI cards. Refer
to 2.8 Install a PCI Expansion Card section when installing
expansion cards.

WARNING!

Unplug the system power cord when adding or removing expansion
cards or other system components. Failure to do so may cause severe
damage to both the motherboard and expansion cards.

3.8.1 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.

IMPORTANT: If using PCI cards on shared slots, make sure that the
drivers support “Share IRQ” or that the cards do not need IRQ
assignments. Conflicts arise between the two PCI groups that makes
the system unstable or cards inoperable.

The following table lists the default IRQ assignments for standard
PC devices. Use this table when configuring your system and for

resolving IRQ conflicts.

Standard Interrupt Assignments

IRQ Priority Standard Function

0 1 System Timer
1 2 Keyboard Controller
2 N/A Programmable Interrupt
3* 11 Communications Port (COM2)
4* 12 Communications Port (COM1)
5* 13 Sound Card (sometimes LPT2)
6 14 Floppy Disk Controller
7* 15 Printer Port (LPT1)
8 3 System CMOS/Real Time Clock
9* 4 ACPI Mode when used
10* 5 IRQ Holder for PCI Steering
11* 6 IRQ Holder for PCI Steering
12* 7 PS/2 Compatible Mouse Port
13 8 Numeric Data Processor
14* 9 Primary IDE Channel
15* 10 Secondary IDE Channel

*These IRQs are usually available for ISA or PCI devices.

ASUS Terminator Barebone System 47

3.8.2 Audio Modem Riser (AMR) Slot

The AMR slot support a specially designed audio and/or modem card
called an Audio Modem Riser (AMR). Main processing is done through
software and controlled by the system chipset. There are two types
of AMR, one defined as primary and another defined as secondary.
You can only use primary AMRs with this motherboard. (NOTE: The
motherboard package does not include the AMR card.)

IMPORTANT

The AMR slot shares the same expansion slot with PCI Slot 6.
Because of space limitation, the AMR slot can support only specially
designed AMR cards. The components of a standard AMR card and
its bracket face toward the edge of the motherboard, while those of a
specially designed AMR card face the expansion slots.

Primary (Blue)/Secondary IDE Connectors (40-1pin IDE1/IDE2)

These connectors support the provided UltraDMA/100/66/33 IDE
hard disk ribbon cable. Connect the cable’s blue connector to
the primary (recommended) or secondary IDE connector, then
connect the gray connector to the UltraDMA/100/66/33 slave
device (hard disk drive) and the black connector to the UltraDMA/
100/66/33 master device. It is recommended that non-UltraDMA/
100/66/33 devices be connected to the secondary IDE connector .
If you install two hard disks, you must configure the second drive
as a slave device by setting its jumper accordingly. Refer to the
hard disk documentation for the jumper settings. BIOS supports
specific device bootup (see 5.6 Boot Menu). If you have more
than two UltraDMA/66/33 devices, purchase another UltraDMA/
100/66/33 cable.

NOTES:

1. Pin 20 on each IDE connector is removed to match the
covered hole on the UltraDMA cable connector. This prevents
incorrect orientation when you connect the cables.

2. The hole near the blue connector on the UltraDMA/66 cable
is intentional.

TIP: You may configure two hard disks to be both Masters with two
ribbon cables – one for the primary IDE connector and another for
the secondary IDE connector.

the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. The fan wiring and plug
may vary depending on the fan manufacturer . The red wire should
be positive while the black should be ground. Connect the fan
plug to the board taking into consideration the polarity of the
connector.

NOTE: Use the “Rotation” signal only with a specially designed fan
with a rotation signal. The Rotations Per Minute (RPM) can be
monitored using ASUS PC Probe (see 4.2 Install the Operating
System).

WARNING!

The CPU and/or motherboard will overheat if there is no airflow across
the CPU and onboard heatsinks. Damage may occur to the

BIOS Information

5.1 Managing and Updating Your BIOS

5.1.1 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 Writer 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 disk. DO NOT copy AUTOEXEC.BAT and 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 boot disk you created.

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

3. Reboot the 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.

IMPORTANT!

If the word “unknown” appears 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.

74 Chapter 5: BIOS Information

5. Select 1. Save Current BIOS to File from the Main menu and
press <Enter>. The Save Current BIOS To File screen appears.

6. Type a filename and the path, for example, A:\XXX-XX.XXX and
then press <Enter>.

ASUS Terminator Barebone System 75

5.1.2 Updating BIOS Procedures

WARNING!

Only update your BIOS if you have problems with your motherboard
and you know that the new BIOS revision will solve your problems.
Careless updating can result in your motherboard having more
problems!

1. Download an updated ASUS BIOS file from the Internet (WWW
or FTP) (see ASUS CONTACT INFORMATION on page 3 for
details) and save to the disk you created earlier.

2. Boot from the disk you created earlier.

3. At the “A:\” prompt, type AFLASH and then press <Enter>.

4. At the Main Menu, type 2 and then press <Enter>. The Update
BIOS Including Boot Block and ESCD screen appears.

5. Type the filename of your new BIOS and the path, for example,

A:\XXX-XX.XXX, and then press <Enter>.
NOTE: To cancel this operation, press <Enter>.

6. When prompted to confirm the BIOS update, press Y to start the
update.

76 Chapter 5: BIOS Information

7. The utility starts to program the new BIOS information into the
flash ROM. The boot block will be updated automatically only when
necessary. This will minimize the chance that a failed update
prevents the system from booting up. When the programming is
finished, Flashed Successfully appears.

8. Follow the onscreen instructions to continue.

WARNING!

If you encounter problems while updating the new BIOS, DO NOT
turn off the system since this might prevent your system from booting
up. Just repeat the process, and if the problem still persists, update
the original BIOS file you saved to the disk above. If the Flash Memory
Writer utility was not able to successfully update a complete BIOS
file, the system may not boot. If this happens, the system will need
servicing.

ASUS Terminator Barebone System 77

5.2 BIOS Setup Program

This motherboard supports a programmable EEPROM that can be
updated using the provided utility as described in 5.1 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 Tests
(POST). Press <Delete> to call up the Setup utility. If you are a little
bit late in pressing the mentioned key, POST continues to run the
test routine, thus preventing you from launching the Setup program.
If you intend to enter 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 is 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
Power-On Self Tests (POST).

NOTE: Because the BIOS software is constantly being updated, the

following BIOS setup screens and descriptions are for reference
