.

Electrostatic discharge (ESD) can damage your system board, proces­sor, disk drives, add-in boards, and other components. Perform the
upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD protection
by wearing an antistatic wrist strap and attaching it to a metal part
of the system chassis. If a wrist strap is unavailable, establish and
maintain contact with the system chassis throughout any procedures
requiring ESD protection.

2.2 System Memory

DDR 1
DDR 2

20

System fan

The system board supports DDR SDRAM DIMM. Double Data
Rate SDRAM (DDR SDRAM) is a type of SDRAM that doubles
the data rate through reading and writing at both the rising and
falling edge of each clock. This effectively doubles the speed of
operation therefore doubling the speed of data transfer.

Refer to chapter 1 (System Memory section) for detailed specifi­cation of the memor y supported by the system board.

BIOS Setting

Configure the system memory in the Advanced Chipset Features
submenu (“DRAM Clock/Drive Control” section) of the BIOS.

Hardware Installation

2.2.1 Installing the DIM Module

A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of
the socket.

Hardware Installation

2.3 CPU

2.3.1 Overview

The system board is equipped with a surface mount Socket A
CPU socket. This socket is exclusively designed for installing an
AMD CPU.

2.3.2 Installing the CPU

1. Make sure the PC and all other peripheral devices connected
to it has been powered down.

2. Disconnect all power cords and cables.

22

3. Locate Socket A on the system board.

4. Unlock the socket by pushing the lever sideways, away from the
socket, then lifting it up to a 90o angle. Make sure the socket is
lifted to at least this angle otherwise the CPU will not fit in
properly.

Lever

Hardware Installation

5. Position the CPU above the socket then align the gold mark
on the corner of the CPU (designated as pin 1) with pin 1 of
the socket.

Important:

Handle the CPU by its edges and avoid touching the pins.

Gold mark

Pin 1

6. Insert the CPU into the socket until it is seated in place. The
CPU will fit in only one orientation and can easily be inserted
without exerting any force.

Important:

Do not force the CPU into the socket. Forcing the CPU into
the socket may bend the pins and damage the CPU.

2.3.3 Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink.
Without sufficient air circulation across the CPU and heat sink,
the CPU will overheat damaging both the CPU and system board.

1. Before you install the fan / heat sink, you must apply a ther­mal paste onto the top of the CPU. The thermal paste, which
is usually supplied together with the CPU, looks somewhat
similar to the one shown below. Do not spread the paste all
over the surface. When you later place the heat sink on top
of the CPU, the compound will disper se evenly.

24

Hardware Installation

Do not apply the paste if the fan / heat sink already has a
patch of thermal paste on its underside. Peel the strip that
covers the paste then place the fan / heat sink on top of the
CPU.

Strip

2. After placing the fan / heat sink on top of the CPU, latch the
retaining clip on one side of the fan heat sink onto the pro­truding tab on the side of the socket.

Retaining clip
Tab

3. Push down the other retaining clip until it latches and lock
onto the protruding tab on that side of the socket. Make sure
there is sufficient air circulation across the CPU fan and heat
sink.

4.1 Desktop Management Interface (DMI)

The system board comes with a DMI built into the BIOS. DMI, along
with the appropriately networked software, is designed to make inven­tory, maintenance and troubleshooting of computer systems easier.
With DMI, a network administrator or MIS engineer can remotely ac­cess some information about a par ticular computer system without
physically going to it. Quite often a service call may be unnecessar y as
the problem can be solved remotely.

The DMI utility in the BIOS automatically records various information
about your system configuration. Information about the type and speed
of CPU, type and amount of memor y for each memory slot, BIOS
revision level, types of add-in PCI boards and components, cer tain re­vision numbers of hardware installed, etc. are automatically detected
and stored in the DMI pool, which is a par t of the mainboard's Plug
and Play BIOS. Additional information, such as ISA based peripherals,
which may not be automatically detected, can be manually recorded
in the DMI pool by using the Add DMI menu. The DMI pool data is
then verified or updated whenever the system hardware or setup is
altered.

4.1.1 Running the DMI Utility

To r un the DMI utility, type: DMICFG.EXE. You can download this utility
from ftp.dfiusa.com - /utilities/DMI directory.

The DMI utility must run in real mode with at least 180K of base
memor y. Memory manager s like HIMEM.SYS (required by Windows)
must not be installed. You may do this by using one of the 3 meth­ods listed below.

1. Boot up from a system diskette without the AUTOEXEC.BAT and
CONFIG.SYS files,

2. “REM” HIMEM.SYS in the CONFIG.SYS, or

3. Press <F5> during bootup to bypass your AUTOEXEC .BAT and
CONFIG.SYS files.

VIA® Service Pack Installation Notes

The “AGP VxD Driver” and “VIA INF Driver” drivers in the “VIA
Service Pack” are supported in Windows® 98, Windows® 98 SE,
Windows® ME and Windows® 2000.

You must first install VIA® Ser vice Pack prior to installing any other
drivers. However, this may not be the case for some AGP cards.
Please read carefully the following information.

Important:

The VGA driver that came with some AGP cards is already
bundled with the AGP VxD driver. Since the version of the
bundled VxD driver may be older than the one provided in the
CD, installing the bundled VxD driver may cause problems. If
you are using this type of card, we recommend that you install
first the AGP card’s VGA driver before installing the VIA Service
Pack.
