BIOS Upgrading Utility and Motherboard
Shield

BIOS Upgrading Utility—One Click is All it T akes!

We are proud to inform you that your new motherboard comes with a BIOS upgrading and
motherboard protection utility. This BIOS updating program makes BIOS updating easy , and
enhances the security and stability of systems built with your motherboard.

BIOS Upgrading Utility Features:

• Anti-Virus BIOS Protection – This motherboard comes with a new hardware monitoring
function that can prevent any unauthorized BIOS updating caused by viruses. Only
this BIOS upgrading utility can update the BIOS for this motherboard.

• BIOS Updating Confidence – Beyond preventing viruses, the BIOS upgrading utility
allows BIOS updating with confidence. In the past, any failure or incorrect operation
during BIOS updating could crash the whole system. Normally the user wouldn’t
have the capability to retrieve and reestablish the system, they could only return the
computer to the supplier for costly, time-consuming repairs. With the enhanced
security of this BIOS upgrading utility, users of this motherboard can completely
avoid these problems. No matter what happens during BIOS updating, the user’s
system can still boot from the floppy drive, allowing the updating command to be
executed again.

• One-Click, Online BIOS Updating – For users of Windows 9X/Me/2000/XP/NT 4.0,
the BIOS upgrading utility allows you to use an innovative online updating technology .
Just one click can detect the BIOS version of your system, download the latest
version, and execute all the updating commands automatically from the Internet.
Restarting the computer completes the BIOS updating. This feature should be very
handy for users who need to update BIOS repeatedly, especially MIS staff. The
online BIOS updating program is included on the drivers CD-ROM included in the box
with your motherboard. Following the step-by-step instructions, you can easily update
or backup your BIOS. (If you have a different OS, see “Chapter 4 BIOS Upgrade”
for your BIOS updating procedure.)

• Linear Overclocking – the BIOS upgrading utility also provides a linear overclocking
function. Users can fine-tune the Front Side Bus (FSB) by increasing or reducing it
by as little as 1.0MHz to find the optimum FSB setting for the system. Should the
FSB be set too high, the system can be returned to the default setting by pressing the
“INS” key.

1.1 Essential Handling Precautions

IMPORT ANT . Read this page before unpacking your motherboard!

••

• Power Supply

••

Be careful! Always ensure that the computer is disconnected from the power supply
when working on the motherboard and its components. (The red power on LED
lights when there is power reaching the motherboard.)

• Static Electricity

Static electricity may cause damage to the delicate integrated circuit chips on your
motherboard. Before handling the motherboard outside of its protective packaging,
ensure that there is no static electrical charge in your body. A static discharge
sufficiently strong enough to damage computer components is not perceptible by a
human. To avoid this risk, please observe these simple precautions while handling
the motherboard and other computer components:

1. If possible, wear an anti-static wrist strap connected to a natural earth ground.

2. Touch a grounded or anti-static surface, or a metal fixture such as a pipe or the
chassis of your system, before touching the motherboard.

3. When you have removed the motherboard from its anti-static packaging, try to
hold it only by the edges, without touching any components.

4. Avoid contacting the components on add-on cards, motherboards, and modules
with the gold-colored connectors which plug into the expansion slots.

5. It is safest to handle system components only by their mounting brackets.

6. Keep components which are not connected to the system in the anti-static packaging
whenever possible.

These precautions help to reduce the risk of static build-up and ensure any static discharge
is harmless to your equipment.

INTRODUCTION 2

••

• AGP Card Use Warning

••

If you are using this motherboard as a DIY (do-it-yourself) system upgrade, and you
intend to transfer and use an older AGP card with this motherboard, please make
sure your AGP card is 1.5V and supports the AGP2.0 standard. Intel has designed
and manufactured the Intel 845 chipset's north bridge to only support 1.5V AGP
cards. This chipset does not support older, 3.3V AGP cards. Use of a 3.3V AGP
card in the AGP slot will damage the motherboard. If this motherboard is part of a
completely new system, it is your system vendor's responsibility to be sure that the
AGP card provided with the system is compatible with the Intel 845 chipset. If you
are performing a DIY system upgrade and don't know the detailed specifications of
your AGP card, please contact your AGP card vendor.

••

• Battery Replacement

••

The battery which holds the system settings memory (CMOS RAM) on your
motherboard should not require replacement for at least five years, and probably
much longer . The battery is located near the bottom of the motherboard as shown
in the pictures in “2.1 Intel 845 Chipset Family Motherboard”. Incorrect computer
time and/or loss of time may indicate a weak motherboard battery . Please replace
your battery only with the same type, or a similar type recommended by the battery
manufacturer. If the battery is replaced incorrectly, there is a risk of a short circuit
or explosion. Used batteries should be disposed of in accordance with the
manufacturer’s instructions and local environmental regulations.

••

• Electric Screwdrivers

••

To reduce the risk of damage to the motherboard due to excessive torque, avoid
setting electric screwdrivers above 7.5 kg/cm.

2.5 Floppy Disk Drive Connector (34-pin FDC)

This connector supports up to two floppy disk drives (FDDs). A FDD ribbon cable is provided
in your motherboard package. After connecting the single end to the board, connect the plug(s)
at the other end to the FDD(s). Remember , the red stripe on the edge of the ribbon cable must
be the nearest to PIN1 or your connection won’t work.

2.6 Primary/Secondary IDE Connectors (Two 40-pin IDE)

The standard configuration of the 845 Chipset Family Motherboard supports two 40-pin IDE
connectors marked as IDE1 (primary channel) and IDE2 (secondary channel). Each channel
supports two IDE devices for a total of four devices. However, the optional IDE RAID controller
comes with additional two IDE connectors (IDE3/primary and IDE4/secondary). These two
channels support up to four more IDE devices. Connect the main HDD, if you are using more
than one, to the “Master” connector (at the end of the cable) and connect it to IDE1 (or IDE3 if
using RAID function) (see important note below). If your HDD supports Ultra DMA/66/100, the
80-wire cable must be used or the HDD won’t be able to reach the faster speed. If you intend
to operate two IDE devices from the same channel, one device must be set to “Master” mode,
the other to “Slave” mode. A HDD, CD ROM or other IDE device can have either setting
depending on the device’s jumper . Refer to the device’s manual for more information.

NOTE: The connectors must be attached to the IDE channels in the correct

direction. Make sure that the red stripe on one edge of the ribbon cable
(this may be faint and could also be a dotted line) is nearest to PIN1 (on
the left for IDE1 and IDE 2 and at the top for IDE3 and IDE4 as the
motherboard is shown in the following pictures).

2.7 Fan Power Connectors

There are three fan power connectors on the motherboard: CPU-F AN, POWER-FAN, and SYS­F AN. Each connector provides +12V power. The cables can only be attached the correct way .
If you try to put them in the wrong way , they won’t fit. These connectors support cooling fans of
500 mA (6W) or less.
