Introducing the Mainboard

IInnttrroodduuccttiioonn

Congratulations on purchasing the K7S5A2 mainboard. The
K7S5A2 mainboard is an ATX mainboard that uses a 4-layer
printed circuit board and measures 244 mm x 304 mm. The
mainboard features a Socket 462 that accommodates AMD
Athlon/Duron processors supporting frontside bus (FSB)
speeds up to 133 MHz.

The K7S5A2 incorporates the SiS735 Northbridge and Sout h­bridge chipsets which combine support for the new high­bandwidth Double Data Rate (DDR) 266 SDRAM, and the AC
97 audio codec.

Note: SDRAM provides 800 MBps or 1 GBps data trans-

fer depending on whether the bus is 100 MHz or
133 MHz. Double Data Rate SDRAM (DDR
SDRAM) doubles the rate to 1.6 GBps or 2.1 GBps
by transferring data on both the rising and falling
edges of the clock. DDR SDRAM uses additional
power and ground lines and requires 184-pin DIMM
modules rather than the 168-pin DIMMs used by
SDRAM.

The K7S5A2 mainboard uses an AMD 462-pin
Socket A that has the following features:

• Supports 100/133 MHz frontside bus (FSB)

• Accommodates AMD Athlon/Duron processors

The SiS735 Northbridge and Southbridge chipsets
are based on an innovative and scalable architec­ture with proven reliability and performance. A few
of the chipset’s advanced features are:

• A low 2.5-volt DDR266 SDRAM power con­sumption which makes it an excellent solution
for notebooks and desktops with a small foot­print

• Support for a 4xAGP interface providing vivid
3D graphics and video performance

• An ATA 100 interface on the chipset, which
helps boost system performance by providing
a high-speed connection to ATA 100 Hard
Disk Drives, delivering maximum sustained
data transfer rates of 100 MB/sec

• Built-in multithreaded I/O link used to enhance
performance, providing enough I/O bandwidth
for throughput up to 1.2 GB/s

Additional key features include support for six
USB ports, an AC 97 link for audio and modem,
hardware monitoring, and ACPI/OnNow power
management.

The mainboard supports both DDR SDRAM and
SDR SDRAM. It accommodates two unbuffered

2.5V 184 pin slots and two unbuffered 3.3V 168

pin slots. Each slot can support up to 512 MB with
a total maximum capacity of 1.0 GB.

The K7S5A2 includes a 4xAGP slot that provides
four times the bandwidth of the original AGP
specification. AGP technology provides a direct
connection between the graphics sub-system and
the processor so that the graphics do not have to
compete for processor time with other devices on
the PCI bus.

Installing the Processor

Caution: When installing a CPU heatsink and cooling fan
make sure that you DO NOT scratch the mainboard or any
of the surface-mount resistors with the clip of the cooling
fan. If the clip of the cooling fan scrapes across the main­board, you may cause serious damage to both the
mainboard and the processor.

On most mainboards, there are small surface-mount resi s­tors near the processor socket, which may be damaged if
the cooling fan is carelessly installed.

Avoid using cooling fans with sharp edges on the fan casing
and the clips. Also, install the cooling fan in a well-lit work
area so that you can clearly see the mainboard and proces­sor socket.

Before installing the Processor

This mainboard automatically determines the CPU clock fre­quency and system bus frequency for processor. You may be
able to change these automatic settings by changing the set­tings in the system Setup Utility. We strongly recommend that
you do not overclock the mainboard to run processors or other
components faster than their rated speed.

Warning: Overclocking components can adversely affect
the reliability of the system and introduce errors into your
system. Overclocking can permanently damage the main­board by generating excess heat in components that are
run beyond the rated limits.

This mainboard has a Socket 462 processor socket. When
choosing a processor, consider the performance requirements
of the system. Performance is based on the processor design,
the clock speed and system bus frequency of the processor,
and the quantity of internal cache memory and external cache
memory.

Follow these instructions to install the CPU:

1. Pull the CPU socket locking lever away from the
socket to unhook it and raise the locking lever to the
upright position.

2. Identify the pin A-1 corner on the CPU socket and the
pin A-1 corner on the processor.

3. Match the pin A-1 corners and insert the processor into
the socket. Do not use force.

4. Swing the locking lever down and hook it under the
latch on the edge of the socket.

K7S5A2 V1.0

Install Memory Modules

This mainboard accommodates 184-pin 2.5V unbuffered
Double Data Rate (DDR) SDRAM memory modules. The
memory chips must be standard or registered SDRAM (Syn­chronous Dynamic Random Access Memory).

This mainboard is capable of auto detecting the type of mem­ory modules (DDR SDRAM or SDRAM) you have installed
and then automatically adj usting the voltage to the appropriate
level.

Note: This mainboard cannot support two different types

of memory modules simultaneously.

The memory bus can run at 100 MHz or 133 MHz. If your
processor operates over a 100 MHz system bus, you can in­stall PC100 or PC133 memory modules that operate over a
100 MHz or 133 MHz memory bus. If your processor operates
over a 133 MHz system bus, you can only install PC133
memory modules that operate over a 133 MHz memory bus.

Note: SDRAM provides 800 MBps or 1 GBps data trans-

fer depending on whether the bus is 100MHz or
133MHz. Double Data Rate SDRAM (DDR
SDRAM) doubles the rate to 1.6 GBps and 2.1
GBps. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules
rather than the 168-pin DIMMs used by SDRAM.

20

K7S5A2 V1.0

Installation Procedure

The mainboard accommodates two memory modules. You
must install at least one module in any of the two slots. Each
module can be installed with 32 MB to 512 MB of memory; to­tal memory capacity is 1 GB.

1. Align the memory module with the slot. The DIMM
slots are keyed with notches and the DIMMs are keyed
with cutouts so that they can only be installed correctly.
Check that the cutouts on the DIMM module edge
connector match the notches in the DIMM slot:

2. Push the latches on each side of the DIMM slot down.

3. Install the DIMM module into the slot and press it firmly
down so that it seats correctly. The slot latches are
levered upwards and latch on to the edges of the
DIMM when it is installed correctly.

Installing a Hard Disk Drive/CD-ROM

This section describes how to install IDE devices such as a
hard disk drive and a CD-ROM drive.

About IDE Devices

Your mainboard has a primary and secondary IDE channel i n­terface (IDE1 and IDE2). An IDE ribbon cable supporting two
IDE devices is bundled with the mainboard. IDE devices have
jumpers or switches that are used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user’s manual.

If you want to install more than two IDE devices, get a second
IDE cable and you can add two more devices to the secon­dary IDE channel.

When installing two IDE devices on one cable, ensure that
one device is set to MASTER and the other device is set to
SLAVE. The documentation of your IDE device explains how
to do this.

About UDMA

This mainboard supports UltraDMA 66/100. UDMA is a tec h­nology that accelerates the performance of devices in the IDE

The computer uses the latest Award BIOS with support for
Windows Plug and Play. The CMOS chip on the mainboard
contains the ROM setup instructions for configuring the mai n­board BIOS.

The BIOS (Basic Input and Output System) Setup Utility dis­plays the system's configuration status and provides you with
options to set system parameters. The parameters are stored
in battery-backed-up CMOS RAM that saves this information
even when the power is turned off. When the system is turned
back on, the system is configured with the values found in
CMOS.

The BIOS Setup Utility enables you to configure:

• Hard drives, diskette drives, and peripherals

• Video display type and display options

• Password protection from unauthorized use

• Power management features

CChhaapptteerr 33

Using BIOS

The settings made in the Setup Utility affect how the computer
performs. Before using the Setup Utility, ensure that you un­derstand the Setup Utility options. Only change settings
appropriate for the way you use the computer.

This chapter provides explanations for Setup Utility options.

K7S5A2 V1.0

The Standard Configuration

A standard configuration has already been set in the Setup
Utility. However, we recommend that you read this chapter in
case you need to make any changes in the future.

This Setup Utility should be used:

• when changing the system configuration

• when a configuration error is detected and you are

prompted to make changes to the Setup Utility

• when trying to resolve IRQ conflicts

• when making changes to the Power Management con-

figuration

• when changing the password or making other changes
to the Security Setup

34

K7S5A2 V1.0

Entering the Setup Utility

When you power on the system, BIOS enters the Power-On
Self Test (POST) routines. POST is a series of built-in diag­nostics performed by the BIOS. After the POST routines are
completed, the following message appears:

Press DEL to enter SETUP

Updating the BIOS

You can download and install updated BIOS for this main­board from the manufacturer's web site. New BIOS provides
support for new peripherals, improvements in performance, or
fixes for known bugs. Install new BIOS as follows:

1. If your mainboard has a BIOS protection jumper,
change the setting to allow BIOS flashing. Refer to
Appendix A for jumper settings.

2. If your mainboard has an item called Firmware Write
Protect in Advanced BIOS features, disable it. Firm­ware Write Protect prevents BIOS from being
overwritten.

3. Create a bootable system disk. Refer to Windows
online help for information on creating a bootable sys­tem disk.

4. Download the Flash Utility and new BIOS file from the
manufacturer's Web site. Copy these files to the sys­tem diskette you created in Step 3.

5. Turn off your computer and insert the system diskette in
your computer's diskette drive. You might need to run the
Setup Utility and change the boot priority items on the
Advanced BIOS Features Setup page, to force your
computer to boot from the floppy diskette drive first.

6. At the A:\ prompt, type the Flash Utility program name
and press <Enter>. You see a screen similar to the fol­lowing:

down the hard disk, turning off the video, suspending to RAM,
and a software power down that allows the system to be
automatically resumed by certain events.

Power Management Timeouts

The power -saving modes can be controlled by timeouts. If the
system is inactive for a time, the timeouts begin counting. If
the inactivity continues so that the timeout period elapses, the
system enters a power-saving mode. If any item in the list of
Reload Global Timer Events is Enabled, then any activity on
that item will reset the timeout counters to zero.
