Motherboard Features
Real-Time Clock
The motherboard has a time-of-day clock and 100-year calendar that will rollover to 2000 at the
turn of the century. A battery on the motherboard keeps the clock current when the computer is
turned off.
NOTE
✏
The recommended method of accessing the date in systems with Intel motherboards is indirectly
from the Real-Time Clock (RTC) via the BIOS. The BIOS on Intel motherboards and baseboards
contains a century checking and maintenance feature that checks the least two significant digits of
the year stored in the RTC during each BIOS request (INT 1Ah) to read the date and, if less than
80 (i.e., 1980 is the first year supported by the PC), updates the century byte to 20. This feature
enables operating systems and applications using the BIOS date/time services to reliably
manipulate the year as a four-digit value.
For more information on proper date access in systems with Intel motherboards please see
http://support.intel.com/support/year2000/paper.htm
Universal Serial Bus (USB) Support
The motherboard has two USB ports. You can connect two USB peripheral devices directly to the
computer without an external hub. To attach more than two devices, connect an external hub to
either of the built-in ports. The motherboard supports the standard universal host controller
interface (UHCI) and takes advantage of standard software drivers written to be compatible with
UHCI. The USB features the following:
• Support for hot swapping Plug and Play devices
• Support for self-identifying peripherals
• Support for up to 127 physical devices
• Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a
shielded cable that meets the requirements for a high-speed USB device.
AGP
The AGP is a high-performance interconnect for graphics-intensive applications, such as 3D
graphics. AGP is independent of the PCI bus and is intended for exclusive use with graphical
display devices. AGP provides these features:
• Pipelined memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for near 100 percent bus efficiency
• AC timing for 133 MHz data transfer rates, allowing real data throughput in excess of
500 MB/sec
12
Page 13
SE440BX-2 Motherboard Product Guide
BIOS
The motherboard’s system BIOS is contained in a flash memory device on the motherboard. The
BIOS provides the power-on self test (POST), the BIOS Setup program, and the PCI and IDE autoconfiguration utilities.
The BIOS is always shadowed. Shadowing allows BIOS routines to be executed from fast 64-bit
onboard DRAM instead of from the slower 8-bit flash memory device.
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can upgrade the BIOS by using a
software utility on a diskette or hard disk, or over a network. For information on upgrading the
BIOS, see Chapter 4.
PCI Auto Configuration
If you install a PCI add-in board in your computer, the PCI auto-configuration utility in the BIOS
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that
add-in board. You do not need to run the BIOS Setup program after you install a PCI add-in
board.
However, PCI add-in boards use the same IRQ resources as ISA add-in boards. If you install both
a PCI and an ISA add-in board, you must specify the IRQ used by the ISA card. The PCI auto
configuration program complies with version 2.1 of the PCI BIOS specification.
IDE Auto Configuration
If you install an IDE device (e.g., a hard drive) in your computer, the IDE auto-configuration
utility in the BIOS automatically detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device.
ISA Plug and Play Capability
The motherboard provides auto configuration of Plug and Play ISA cards and resource
management for legacy (non-Plug and Play) ISA cards when used with the ISA Configuration
Utility (ICU) or a Plug and Play compatible operating system like Windows 95 and Windows 98.
To obtain the ICU, contact your computer supplier.
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the computer. A supervisor password and a user password can be set for the
Setup program and for booting the computer, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all the Setup options in
the Setup program. This is supervisor mode.
• The user password gives restricted access to view and change Setup options in the Setup
program. This is user mode.
13
Page 14
Motherboard Features
• If only the supervisor password is set, pressing the <Enter> key at the password prompt of the
Setup program gives the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the supervisor
password or the user password to access Setup.
• Setting a user password restricts who can boot the computer. The password prompt is
displayed before the computer is booted. If only the supervisor password is set, the computer
boots without asking for a password. If both passwords are set, you can enter either password
to boot the computer.
Expansion Slots
The motherboard has six expansion slots for installing add-in boards, like network cards, that
expand the capabilities of your computer. The expansion slots are as follows:
• One ISA slot
• One shared PCI/ISA slot
• Three PCI slots
• One AGP slot
Power Management
The motherboard supports two types of power management — Advanced Power Management
(APM) and Advanced Configuration and Power Interface (ACPI).
Advanced Power Management (APM)
APM’s energy saving standby mode can be initiated in the following ways:
• Specify a time-out period in Setup
• Press the suspend/resume switch connected to the front panel sleep connector
• Use an operating system option, such as the Suspend menu item in Windows 95 and
Windows 98
In standby mode, the motherboard can reduce power consumption by spinning down hard drives,
†
and reducing power to or turning off VESA
mode can be enabled or disabled in Setup (see Chapter 3).
While in standby mode, the system retains the ability to respond to external interrupts and service
requests, such as incoming faxes or network messages. Any keyboard or mouse activity brings the
system out of standby mode and immediately restores power to the monitor.
The BIOS enables APM by default; but the operating system must support an APM driver for the
power-management features to work. For example, Windows 95 and Windows 98 support the
power-management features upon detecting that APM is enabled in the BIOS.
DPMS-compliant monitors. Power-management
14
Page 15
SE440BX-2 Motherboard Product Guide
Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. ACPI requires an ACPI-aware operating system. ACPI features include:
• Plug and Play (including bus and device enumeration) and APM functionality normally
contained in the BIOS
• Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video monitor, and hard disk drives
• Methods for achieving less than 30-watt system operation in the Power On Suspend sleeping
state, and less than 5-watt system operation in the Suspend to Disk sleeping state
• A Soft-off feature that enables the operating system to power off the computer
• Support for multiple wake up events
• Support for a front panel power and sleep mode switch
Battery
A battery on the motherboard keeps the clock and the values in CMOS RAM current when your
computer is turned off. To replace the battery, see Chapter 2.
Wake on Ring
Wake on Ring enables the computer to wake from sleep or soft-off mode when a call is received
on a telephony device, such as a modem, configured for operation on Serial Port A. The first
incoming call powers up the computer. A second call must be made to access the computer. To
access this feature use the Wake on Ring connector. See Chapter 5 for the location and pinouts of
the Wake on Ring connector.
Wake on LAN Technology (Optional)
Wake on LAN technology enables remote wakeup of the computer through a network. Wake on
LAN technology requires a PCI add-in network interface card (NIC) with remote wakeup
capabilities. The remote wakeup connector on the NIC must be connected to the onboard Wake on
LAN technology connector. The NIC monitors network traffic at the MII interface; upon
†
detecting a Magic Packet
access this feature use the Wake on LAN technology connector. See Chapter 5 for the location and
pinouts of the Wake on LAN technology connector.
CAUTION
For Wake on LAN, the 5-V standby line for the power supply must be capable of delivering +5 V
5 % at 720 mA. Failure to provide adequate standby current when implementing Wake on LAN,
±
can damage the power supply.

4 Upgrading the BIOS
This chapter describes how to upgrade the BIOS and how to recover the BIOS if an upgrade fails.
Preparing for the Upgrade
Before you upgrade the BIOS, prepare by:
• Obtaining the BIOS upgrade file
• Recording the current BIOS settings
• Creating a bootable diskette
• Creating the BIOS upgrade diskette
Obtaining the BIOS Upgrade File
You can upgrade to a new version of the BIOS by using the BIOS upgrade file. The BIOS upgrade
file is a compressed self-extracting archive that contains all the files you need to upgrade the
BIOS. The BIOS upgrade file contains:
• New BIOS files
• BIOS recovery files
• Intel Flash Memory Update Utility
You can obtain the BIOS upgrade file through your computer supplier or from the Intel World
Wide Web site:
http://support.intel.com/support/motherboards/desktop/
NOTE
✏
Please review the instructions distributed with the update utility before attempting a BIOS
upgrade.
The Intel Flash Memory Update Utility allows you to:
• Upgrade the BIOS in flash memory.
• Update the language section of the BIOS.
Recording the Current BIOS Settings
1. Boot the computer and press <F2> when you see the message:
Press <F2> Key if you want to run SETUP
NOTE
Do not skip step 2. You will need these settings to configure your computer at the end of the
upgrade procedure.
2. Write down the current settings in the BIOS Setup program.

Page 48
Upgrading the BIOS
Creating a Bootable Diskette
NOTE
✏
If your drive A is an LS-120 diskette drive, you must use a 1.44-MB diskette as the bootable BIOS
upgrade diskette. The computer is unable to recover a BIOS from an LS-120 diskette.
1. Use a DOS, Windows 95, or Windows 98 system to create the diskette.
2. Insert a diskette in diskette drive A.
3. At the C:\ prompt, for an unformatted diskette, type:
format a:/s
or, for a formatted diskette, type:
sys a:
4. Press
<Enter>
.
Creating the BIOS Upgrade Diskette
Obtain the BIOS upgrade file as described in “Obtaining the BIOS Upgrade File” and then:
1. Then copy the BIOS upgrade file to a temporary directory on your hard disk.
2. From the C:\ prompt, change to the temporary directory.
3. To extract the file, type the name of the BIOS upgrade file, for example:
10006BI1.EXE
4. Press
<Enter>
. The extracted file contains the following files:
LICENSE.TXT
BIOINSTR.TXT
BIOS.EXE
5. Read the
BIOINSTR.TXT

Recovering the BIOS
It is unlikely that anything will interrupt the BIOS upgrade; however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover the BIOS if an upgrade fails.
The following procedure uses recovery mode for the Setup program. See Chapter 3 for more
information on Setup modes.
NOTE
Because of the small amount of code available in the non-erasable boot block area, there is no
video support. You will not see anything on the screen during this procedure. Monitor the
procedure by listening to the speaker and looking at the diskette drive LED.
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external
peripherals.
2. Remove the computer cover and locate the configuration jumper block (J8A1) (see Figure 7).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.
J8A1

5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to
boot. The recovery process will take a few minutes.
6. Listen to the speaker.
• Two beeps and the end of activity in drive A indicate successful BIOS recovery.
• A series of continuous beeps indicates failed BIOS recovery.
7. If recovery fails, return to step 1 and repeat the recovery process.
8. If recovery is successful, turn off the computer and disconnect its power cord.
9. Remove the computer cover and continue with the following steps.
10. On the jumper block (J8A1), move the jumper back to pins 1-2 as shown below to set normal
mode for Setup.

• Damage to wires that could cause a short circuit
Observe all warnings and cautions that instruct you to refer computer servicing to qualified
technical personnel.
WARNING
Do not open the power supply. Risk of electric shock and burns from high voltage and rapid
overheating. Refer servicing of the power supply to qualified technical personnel.
Installation Instructions
CAUTION
Follow these guidelines to meet safety and regulatory requirements when installing this board
assembly.
Read and adhere to all of these instructions and the instructions supplied with the host computer
and associated modules. If the instructions for the host computer are inconsistent with these
instructions or the instructions for associated modules, contact the supplier’s technical support to
find out how you can ensure that your computer meets safety and regulatory requirements. If you
do not follow these instructions and the instructions provided by host computer and module
suppliers, you increase safety risk and the possibility of noncompliance with regional laws and
regulations.

SE440BX-2 Motherboard Product Guide
Ensure Electromagnetic Compatibility (EMC)
Before computer integration, make sure that the power supply and other modules have passed
EMC testing using a motherboard with a microprocessor from the same family and operating at the
same (or higher) speed as the microprocessor on this motherboard.
In the installation instructions for the host chassis, power supply, and other modules pay close
attention to the following:
• Certifications
• External I/O cable shielding and filtering
• Mounting, grounding, and bonding requirements
• Keying connectors when mismating of connectors could be hazardous
If the power supply and other modules have not passed applicable EMC testing before integration,
EMC testing must be conducted on a representative sample of the newly completed computer.
Ensure Host Computer and Accessory Module Certifications
Make sure that the host computer, any added subassembly, such as a board or drive assembly, and
internal or external wiring, are certified for the region(s) where the end-product will be used.
Marks on the product are proof of certification. Certification marks are as follows:
In Europe
The CE marking signifies compliance with all relevant European requirements. If the host
computer does not bear the CE marking, obtain a supplier’s Declaration of Conformity to the
appropriate standards required by the European EMC Directive and Low Voltage Directive. Other
directives, such as the Machinery and Telecommunications Directives, may also apply depending
on the type of product. No regulatory assessment is necessary for low voltage DC wiring used
internally or wiring used externally when provided with appropriate overcurrent protection.
Appropriate protection is provided by a maximum 8-Amp current limiting circuit or a maximum
5-Amp fuse or positive temperature coefficient (PTC) resistor. All Intel motherboards now have
PTCs on all external ports that provide DC power externally.
In the United States
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or
ETL signifies compliance with safety requirements. External wiring must be UL Listed and
suitable for the intended use. Internal wiring must be UL Listed or Recognized and rated for
applicable voltages and temperatures. The FCC mark (Class A for commercial or industrial only
or Class B for residential) signifies compliance with electromagnetic interference requirements.
In Canada
A nationally recognized certification mark such as CSA or cUL signifies compliance with safety
requirements. No regulatory assessment is necessary for low voltage DC wiring used internally or
wiring used externally when provided with appropriate overcurrent protection. Appropriate
protection is provided by a maximum 8-Amp current limiting circuit or a maximum 5-Amp fuse or
positive temperature coefficient (PTC) resistor. All Intel motherboards now have PTCs on all
external ports that provide DC power externally.

Regulatory and Integration Information
Prevent Power Supply Overload
Unless the power supply has inherent overcurrent protection, do not overload the power supply
output. To avoid overloading the power supply, make sure that the calculated total current load of
all the modules within the computer is less than the output current rating of the power supply. If
you do not do this, the power supply could overheat, catch fire, or damage the insulation that
separates hazardous AC line circuitry from low-voltage user accessible circuitry. If the load drawn
by a module cannot be determined by the markings and instructions supplied with the module,
contact the module supplier’s technical support.
Place Battery Marking on the Computer
There is insufficient space on this motherboard to provide instructions for replacing and disposing
of the battery. The following warning must be placed permanently and legibly on the host
computer as near as possible to the battery.
WARNING
Danger of explosion if battery is incorrectly replaced.
Replace with only the same or equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer’s instructions.
Use Only for Intended Applications
This product was evaluated for use in computers that will be installed in offices, homes, schools,
computer rooms, and similar locations. The suitability of this product for other applications, (such
as medical, industrial, alarm systems, and test equipment) may require further evaluation.
