Motherboard Features  
Microprocessor  
The motherboard supports a single Pentium II processor operating at any of the Pentium II  
processor speeds, voltages, and bus frequencies. Processors are not included with the SE440BX  
motherboard and must be purchased separately.  
The processor is packaged in a Single Edge Contact (S.E.C.) cartridge. The cartridge includes the  
processor core, second-level cache subsystem, thermal plate, and back cover.  
The processor connects to the motherboard through the Slot 1 connector, a 242-pin edge connector.  
When mounted in Slot 1, the processor is secured by a retention mechanism attached to the  
motherboard. A passive heatsink is stabilized by the heatsink support.  
Microprocessor Upgrades  
The motherboard can be upgraded with Pentium II processors that run at higher speeds. To  
upgrade the processor, use the BIOS configuration mode to change the processor speed, see  
Chapter 2.  
Main Memory  
The motherboard has three sockets for installing dual inline memory modules (DIMMs).  
Minimum memory size is 8 MB; maximum memory size is 384 MB. To install memory, see  
Chapter 2.  
Second Level Cache Memory  
The second-level cache is located in the S.E.C. cartridge. The cache includes synchronous  
pipelined burst static RAM (PBSRAM) and tag RAM. There are four PBSRAM components  
totaling 512 KB in size. All supported onboard memory is cacheable.  
PCI Enhanced IDE Interface  
The PCI enhanced IDE interface handles the exchange of information between the processor and  
peripheral devices like hard disks and add-in boards inside the computer. The interface supports:  
•
•
•
•
•
Up to four IDE devices such as hard drives  
ATAPI devices  
PIO mode 3 and PIO mode 4 devices  
Up to four PCI cards or up to two ISA cards and three PCI cards  
Logical block addressing (LBA) of hard drives larger than 528 MB and extended cylinder head  
sector (ECHS) translation modes  
•
Support for laser servo (LS-120) drives  
10  
SE440BX Motherboard Product Guide  
Input/Output (I/O) Controller  
The I/O controller handles the exchange of information between the processor and external devices  
like the mouse and keyboard or a printer that are connected to the computer. The controller  
features the following:  
•
•
•
Integrated keyboard and mouse controller  
Industry standard diskette drive controller  
One multimode bi-directional parallel port  
Standard mode: Centronics-compatible operation  
High speed mode: support for enhanced capabilities port (ECP) and enhanced parallel port  
(EPP)  
•
•
Two serial ports  
Flexible IRQ and DMA mapping for Windows† 95  
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  
11  
Motherboard Features  
•
•
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.  
A.G.P.  
The A.G.P. is a high-performance interconnect for graphics-intensive applications, such as 3D  
graphics. A.G.P. is independent of the PCI bus and is intended for exclusive use with graphical  
display devices. A.G.P. 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  
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 auto-  
configuration 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.  
12  
SE440BX Motherboard Product Guide  
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. 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.  
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 five 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  
Three PCI slots  
One shared PCI/ISA slot  
13  
Motherboard Features  
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  
In standby mode, the motherboard can reduce power consumption by spinning down hard drives,  
and reducing power to or turning off VESA† DPMS-compliant monitors. Power-management  
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 supports the power-management  
features upon detecting that APM is enabled in the BIOS.  
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.  
14  
SE440BX Motherboard Product Guide  
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 COM1. 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†, the NIC asserts a wakeup signal that powers up the computer. To  
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.  
Hardware Monitor (Optional)  
The optional hardware monitor subsystem provides low-cost instrumentation capabilities. The  
features of the hardware monitor subsystem include:  
•
•
•
Support for an optional chassis intrusion connector  
An integrated ambient temperature sensor  
Fan speed sensors that monitor the fan 1 and fan 2 connectors (see Figure 15 for the location of  
these connectors on the motherboard)  
•
Power supply voltage monitoring to detect levels above or below acceptable values  
When suggested ratings for temperature, fan speed, or voltage are exceeded, an interrupt is  
activated. The hardware monitor component connects to the system management (SM) bus.

How to Replace the Battery  
When your computer is turned off, a lithium battery maintains the current time-of-day clock and  
the values in CMOS RAM current. Figure 14 shows the location of the battery.  
The battery should last about seven years. When the battery begins to die, it loses voltage; when  
the voltage drops below a certain level, the Setup program settings stored in CMOS RAM (for  
example, the date and time) might not be accurate. Replace the battery with an equivalent one.  
WARNING  
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or  
equivalent type recommended by the equipment manufacturer. Discard used batteries according  
to manufacturer’s instructions.  
ATTENTION  
Il y a danger d’explosion s’il y a remplacement incorrect de la batterie. Remplacer uniquement  
avec une batterie du méme type ou d’un type recommandé par le constructeur. Mettre au rébut  
les batteries usagées conformément aux instructions du fabricant.  
ADVARSEL!  
Lithiumbatteri - Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri  
af samme fabrikat og type. Levér det brugte batteri tilbage til leverandøren.  
ADVARSEL  
Lithiumbatteri - Eksplosjonsfare. Ved utskifting benyttes kun batteri som anbefalt av  
apparatfabrikanten. Brukt batteri returneres apparatleverandøren.  
VARNING  
Explosionsfara vid felaktigt batteribyte. Använd samma batterityp eller en ekvivalent typ som  
rekommenderas av apparattillverkaren. Kassera använt batteri enligt fabrikantens instruktion.  
VAROITUS  
Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan

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://developer.intel.com/  
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.  
45  
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 or Windows 95 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 LICENSE.TXTfile, which contains the software license agreement, and the  
BIOINSTR.TXTfile, which contains the instructions for the BIOS upgrade.  
6. Insert the bootable diskette into drive A.  
7. To extract the BIOS.EXEfile to the diskette, change to the temporary directory that holds the  
BIOS.EXEfile and type:  
BIOS A:  
8. Press <Enter>.  
9. The diskette now holds the new BIOS files, the Intel Flash Update Utility, and the recovery  
files.  
Upgrading the BIOS  
1. Boot the computer with the BIOS upgrade diskette in drive A. The flash memory update  
utility screen appears.  
2. Select Update Flash Memory From a File.  
3. Select Update System BIOS. Press <Enter>.  
4. Use the arrow keys to select the correct .biofile. Press <Enter>.  
46  
SE440BX Motherboard Product Guide  
5. When the utility asks for confirmation that you want to flash the new BIOS into memory,  
select Continue with Programming. Press <Enter>.  
6. When the utility displays the message upgrade is complete, remove the diskette. Press  
<Enter>.  
7. As the computer boots, check the BIOS identifier (version number) to make sure the upgrade  
was successful.  
8. To enter the BIOS Setup program, press <F2>when you see the message:  
Press <F2> Key if you want to run SETUP  
9. For proper operation, load the BIOS Setup program defaults. To load the defaults, press <F9>.  
10. To accept the defaults, press <Enter>.  
11. In Setup, set the options to the settings you wrote down before beginning the BIOS upgrade.  
12. To save the settings, press <F10>.  
13. To accept the settings, press <Enter>.  
14. Turn off the computer and reboot.  
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

OM07073  
4. Insert the bootable BIOS upgrade diskette into diskette drive A.  
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.  
47  
Upgrading the BIOS  
10. On the jumper block (J8A1), move the jumper back to pins 1-2 as shown below to set normal  
mode for Setup.  
J8A1

OM07072  
11. Leave the upgrade diskette in drive A, replace the computer cover, and connect the computer’s  
power cord.  
12. Turn on the computer and continue with the BIOS upgrade (see page 46).  
Changing the BIOS Language  
You can use the BIOS upgrade utility to change the language the BIOS uses for messages and the  
Setup program. Use a bootable diskette containing the Intel Flash Memory Update Utility and  
language files (see “Upgrading the BIOS” on page 46).  
1. Boot the computer with the bootable diskette in drive A. The BIOS upgrade utility screen  
appears.  
2. Select Update Flash Memory From a File.  
3. Select Update Language Set. Press <Enter>.  
4. Select drive A and use the arrow keys to select the correct .lngfile. Press <Enter>.  
5. When the utility asks for confirmation that you want to flash the new language into memory,  
select Continue with Programming. Press <Enter>.  
6. When the utility displays the message upgrade is complete, remove the diskette. Press  
<Enter>.  
7. The computer will reboot and the changes will take effect.

SE440BX 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.  
61  
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.
