This chapter gives step-by-step instructions
on how to install components into the
barebone system.
ASUS Terminator 1 A7VT barebone system
Basic Installation
17
2.1 Preparation
Before you proceed, make sure that you have all the components that you
plan to install in the system.
Basic components to install
1. Central processing unit (CPU)
2. DDR Dual Inline Memory Module (DIMM)
3. Expansion card(s)
4. Hard disk drive
5. Second optical drive
Tool
Phillips (cross) screw driver
2.2 Before you proceed
Take note of the following precautions before you install components into
the system.
• Use a grounded wrist strap or touch a safely grounded object or
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
The motherboard comes with an onboard standby power LED. This LED
lights up to indicate that the system is ON, in sleep mode or in soft-off
mode, and not powered OFF. Unplug the power cable from the power
outlet and make sure that the standby power LED is OFF before installing
any system component.

2.5 Installing a CPU
The motherboard comes with a surface mount 462-pin Zero Insertion
Force (ZIF) socket designed for the AMD Athlon™ and AMD Duron™
processors.
Take note of the marked corner
(with gold triangle) on the CPU.
This mark should match a specific
corner on the socket to ensure
correct installation.
Gold triangle
CPU installation
To install the CPU.
1. Locate the 462-pin ZIF socket on the motherboard.
22
Chapter 2: Basic Installation
2. Unlock the socket by pressing
the lever sideways, then lift it up
to a 90°-100° angle.
Socket lever
Make sure that the socket lever is lifted up to a 90°-100° angle;
otherwise, the CPU does not fit in completely.
3. Position the CPU above the
socket such that the CPU corner
with the gold triangle matches
the base of the socket lever.
90°-100°
angle
4. Carefully insert the CPU into the
socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into
the socket to prevent bending the pins and damaging the CPU!
5. When the CPU is in place, push
down the socket lever to secure
the CPU. The lever clicks on the
side tab to indicate that it is
locked.

2.6 Installing the fan and heatsink assembly
The processor requires a heatsink and fan assembly to ensure optimum
thermal condition and system performance.
Make sure that you properly install the CPU heatsink and fan to avoid
thermal problems.
Follow these steps to install the
CPU heatsink and fan.
1. Position the fan and heatsink
assembly on top of the
installed CPU such that the
heatsink fins are perpendicular
to the DDR sockets and PCI
slots.
2. Align one end of the heatsink
bracket to the protruding tabs
on the CPU socket. Hook the
holes of the bracket to the
protruding tabs, making sure
that they fit properly.
3. Using a flat screwdriver,
carefully hook the other end of
the heatsink bracket to the
tabs on the base of the CPU
socket. This secures the fan
and heatsink assembly.

2.7 Installing system memory
The motherboard comes with two Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 2 GB
system memory using unbuffered ECC or non-ECC PC2700/2100 DIMMs.

2.7.1 Memory configurations
You may install any DDR DIMMs with 64 MB, 128 MB, 256 MB, 512 MB,
and 1 GB densities into the DIMM sockets.
Memory frequency/CPU FSB synchronization
CPU FSB DDR DIMM Type Memory Frequency

166 MHz PC2700/PC2100/PC1600 333/266/200 MHz
• When using 100 MHz CPU FSB, any DDR DIMM you installed may
run only at a maximum of 266 MHz due to chipset limitation.
• If you are using CPU FSB other than 100 MHz and installed
400 MHz DDR DIMMs, the memory frequency downgrades to
333 MHz.
26
Chapter 2: Basic Installation
2.7.2 DIMM installation
Follow these steps to install a DDR
DIMM.
1. Locate the two DIMM sockets
on the motherboard.
2. Unlock a socket by pressing
the retaining clips outward.
3. Align a DIMM on the socket
such that the notch on the
DIMM matches the break on
the socket.

4. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the
DIMM is properly seated.
A DDR DIMM is keyed with a notch so that it fits in only one direction.
DO NOT force a DIMM into a socket to avoid damaging the DIMM.

2.8 Installing an expansion card
In the future, you may need to install expansion cards. The motherboard
has one 32-bit PCI slot and one Accelerated Graphic Port (AGP) slot. The
following sub-sections describe the slots and the expansion cards that
they support.
2.8.1 Expansion slots
PCI slot
The PCI slot supports PCI slots such as a LAN card, SCSI card, USB
card, and other cards that comply with PCI specifications
AGP slot
The AGP slot supports AGP 4x cards. When you buy an AGP card, make
sure that you ask for one with 1.5V specification.
Install only +1.5V AGP cards. The motherboard does not support 3.3V
AGP cards.
Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage the motherboard.
28
Chapter 2: Basic Installation
2.8.2 Expansion card installation
Follow these steps to install a PCI
or AGP card.
1. Place the chassis on its side.
2. Remove the metal bracket
opposite the slot that you wish
to use.
3. Align the card golden fingers
to the slot and its metal
bracket to the slot opening on
the chassis.
4. Press the card firmly until it is
properly seated on the slot.
5. Secure the card to the chassis
with a bracket screw.
Metal bracket
PCI slot (PCI1)
AGP slot (AGP1)
2.8.3 Configuring an expansion card
After installing the expansion card, configure it by adjusting the software
settings.
1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 5 for information on BIOS setup.
