Chapter 1: Product introduction

Gigabit LAN solution

The Intel® 82547GI Gigabit Ethernet controller allows full-duplex Gigabit
performance on LAN on Motherboard (LOM) applications through the
Communication Streaming Architecture (CSA). Instead of connecting to
the PCI bus, the controller connects to the dedicated CSA bus on the
Memory Controller Hub (MCH) thus reducing the PCI bottlenecks by
freeing the PCI bus for other I/O operations.

The Intel

®

82541GI Gigabit Ethernet controller is also onboard to support

32-bit LAN through the PCI bus.

2.1 Before you proceed

Take note of the following precautions before you install motherboard
components or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any
component.

2. Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.

3. Hold components by the edges to avoid touching the ICs on them.

4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.

5. Before you install or remove any component, ensure that the

ATX power supply is switched off or the power cord is
detached from the power supply. Failure to do so may cause

severe damage to the motherboard, peripherals, and/or
components.

When lit, the green LED (SB_PWR1) indicates that the system is ON,
in sleep mode, or in soft-off mode, a reminder that you should shut
down the system and unplug the power cable before removing or
plugging in any motherboard component.

This warning LED (LED1) lights up if you installed two CPUs of
different type/voltage. You must install identical CPUs on this
motherboard.

2.4 System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets.

The following figure illustrates the location of the DDR DIMM sockets.

2.4.2 Memory configurations

You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into
the DIMM sockets using the memory configurations in this section.

Important notes

1. Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations in Table 1.

2. In dual-channel configurations, install only identical (the same
type and size) DDR DIMM pairs for each channel.

3. Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.

4. Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to Table 2.

5. DIMMs installed into any three sockets will function in single-
channel mode.

6. When all four sockets are populated with 1GB DIMMs (total 4GB),
the system may detect only about 3.6GB (less than 4GB) due to
Southbridge resource allocation.

in a chassis).

3. Remove the bracket opposite the slot that you intend to use. Keep the
screw for later use.

4. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

2.5.2 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.

3.1 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the system
chassis.

4. Connect the power cord to a power outlet that is equipped with a surge
protector.

5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power

6. After applying power, the power LED on the system front panel case lights
up. For SSI-type power supplies, the system LED lights up when you
press the power switch. If your monitor complies with “green” standards or
if it has a “power standby” feature, the monitor LED may light up or switch
between orange and green after the system LED turns on. The system
then runs the power-on tests. While the tests are running, the BIOS beeps
(see BIOS beep codes table below) or additional messages appear on
the screen. If you do not see anything within 30 seconds from the time you
turned on the power , the system may have failed a power-on test. Check
the jumper settings and connections or call your retailer for assistance.

4.2 BIOS Setup program

This motherboard includes a Flash ROM that you can update using the
provided utility described in section “4.1 Managing and updating your
BIOS.”

Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password feature or make changes to the
power management settings. This requires you 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 Flash ROM.

The Flash ROM on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to run
this program. Press <Delete> during the Power-On Self Test (POST) to
enter the Setup utility, otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, 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.
Do this last option only if the first two failed.

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.

Because the BIOS software is constantly being updated, the following
BIOS setup screens and descriptions are for reference purposes only,
and may not exactly match what you see on your screen.
