1 Motherboard Description
1.1 Overview
The VS440FX design will accept Intel’s Pentium® Pro processors at speeds of 150 MHz,
166 MHz, 180 MHz and 200 MHz. The memory subsystem supports up to 256 MB of DRAM
using standard 72-pin SIMM† sockets that accept Fast Page Mode (FPM) and Extended Data Out
(EDO) memory. A type 8 Zero Insertion Force (ZIF) socket provides an upgrade path to future
Pentium Pro Overdrive® processors.
The VS440FX motherboard utilizes Intel's 82440FX PCIset. The Intel 82371SB PCI/ISA IDE
Xccelerator (PIIX3) provides an integrated Bus Mastering IDE controller with two high
performance IDE interfaces for up to four devices (such as hard drives or CD-ROM). The National
PC87308 Super I/O controller integrates the standard PC I/O functions: floppy interface, two
FIFO serial ports, one EPP/ECP capable parallel port, a Real Time Clock, keyboard controller, and
support for an IrDA and Consumer Infra Red compatible interface.
To provide for the increasing number of multimedia applications, a Crystal CS4232 audio CODEC
is integrated onto the motherboard. The CS4232 provides 16-bit stereo, Sound Blaster† Pro
compatible audio.
Up to four PCI local bus slots provide a high bandwidth data path for data-movement intensive
functions such as video or networking. PCI Bridge support in the BIOS allows for further
expansion of the system with PCI peripherals. Up to four ISA slots complete the I/O mix. A total
of seven expansion slots may be populated with full length add-in cards, since one PCI and ISA
slot share the same chassis I/O panel.

Figure 2. Motherboard Dimensions
1.4 Microprocessor
The VS440FX motherboard operates with 2.1 V to 3.5 V Pentium Pro processors. An on-board
voltage regulator circuit provides the required voltages from the 5 V and 3.3 V taps off the power
supply. The on-board voltage regulator makes use of the VID capabilities to automatically adjust
its voltage output to match that of the installed processor.. Pentium Pro processors running at 150,
166, 180, and 200 MHz are supported.
The Pentium Pro processor integrates second level cache and cache controller that were previously
implemented on the motherboard. The internal non-blocking L2 cache on the 150, 180 and
200 MHz processors is 256 KB, while the 166 and a second version of the 200 MHz processors
integrate a 512 KB cache.
The Pentium Pro processor maintains full backward compatibility with the 8086, 80286,
TM
TM
Intel386 , Intel486 and Pentium processors. It also has a numeric coprocessor that significantly
increases the speed of floating point operations, while maintaining backward compatibility with the
i486DX math coprocessor and complying with ANSI/IEEE standard 754-1985.

VS440FX Motherboard Technical Product Specification
1.4.1
Microprocessor Upgrade
Socket 8 is a 387-pin, modified staggered pin grid array (SPGA) zero insertion force (ZIF) socket,
along with a programmable voltage regulator for the CPU core. It provides users with a
performance upgrade path to Pentium Pro OverDrive technology. The voltage regulator
programming is automatic and controlled by the VID pins of the processor.
1.4.2
Microprocessor Heatsink and Clips
An approved Pentium Pro heatsink is necessary for proper thermal dissipation in an ATX v. 1.1
compliant chassis. The processor/heatsink assembly must be securely fastened to the Socket 8 ZIF
socket by two clips. These clips fit over the heatsink assembly and attach to the outer wide tabs of
the Socket 8 assembly.
CAUTION
Do not use the older style of bail-wire clips for securing the heatsink assembly. These clips have
been found to damage the motherboard when installed or removed incorrectly.
1.5 Memory
1.5.1
Main System Memory
The motherboard provides four 72-pin SIMM sockets that make it possible to install up to 256 MB
of RAM. The sockets support 1M x 32 (4 MB) single-sided modules, 2M x 32 (8 MB), 4M x 32
(16 MB), 8M x 32 (32 MB) and 16M x 32 (64 MB) single- or double-sided modules. Minimum
memory size is 8 MB and maximum memory size, using four 16M x 32 SIMM modules, is
256 MB. Memory timing requires 60 ns fast page devices or, for optimum performance, 60 ns
EDO DRAM. Both parity and non-parity memory are supported as well as ECC.
The four sockets are arranged in two banks of two sockets each. The sockets are designated Bank
0 and Bank 1. Each bank provides a 64/72-bit wide data path. Both SIMMs in a bank must be of
the same memory size and type, although the different types and sizes of memory may differ
between banks. Bank 0 only, Bank 1 only, or both of the banks may be populated. There are no
jumper settings required for the memory size or type, which is automatically detected by the
system BIOS. Use only tin lead SIMMs when adding DRAM.
✏
NOTE
64 MB SIMMs using the 16 Mb technology are not qualified for use on the VS440FX motherboard
due to electrical loading characteristics. 64 MB SIMMs using 64 MB technology have not been
qualified, however, they will be supported by the motherboard when they become available,
depending upon the individual characteristics of the memory module.
10
Motherboard Description
1.5.1.1
EDO DRAM
Extended Data Out (or Hyper Page) DRAM is designed to improve the DRAM read performance.
EDO DRAM holds the memory data valid until the next memory access cycle, unlike standard fast
page mode DRAM that tri-states the memory data when the precharge cycle occurs, prior to the
next memory access cycle. EDO DRAM timings are X-2-2-2 compared to FPM timings of
X-3-3-3.
1.5.1.2
Parity/ECC DRAM
Memory error checking and correction is supported via parity or ECC SIMMs. Parity or ECC
SIMMs are automatically detected. However, the user must enter Setup to configure the SIMMs
for either Parity or ECC operation. Parity memory will detect single bit errors. Ecc memory will
detect double bit errors and correct single bit errors. Errors may be generated by a defective
memory module, different speeds of memory modules, or DMA or memory conflicts.
1.6 Chipset
The Intel 82440FX PCIset consists of the 82441FX PCI Bridge and Memory controller (PMC) and
the 82442FX Data Bus Accelerator (DBX). The Intel 82371SB PCI ISA/IDE Xccelerator (PIIX3)
bridge, provides the connection between the ISA and PCI buses.

− Programmable system management interrupt (SMI)
IDE Support
The motherboard provides two independent high performance bus-mastering PCI IDE interfaces
capable of supporting PIO Mode 3 and Mode 4 devices. The system BIOS supports Logical Block
Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI
(e.g., CD-ROM) devices on both IDE interfaces. Detection of IDE device transfer rate and
translation mode capability is automatically determined by the system BIOS.
Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In true
multi-tasking operating systems like Windows† 95, the CPU bandwidth freed up by using bus
mastering IDE can be used to complete other tasks while disk transfers are occurring. When used
in conjunction with the appropriate driver for the Windows 95 environment, the IDE interface can
operate as a PCI bus master capable of supporting PIO Mode 4 devices with transfer rates of up to
16 MB/sec.
Detailed information on the PCIset is available in the Intel 82440FX PCISet data sheet
1.7 PC87308 Super I/O Controller
Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is
incorporated into a single component, the National Semiconductor PC87308. The PC87308 is a
fully Plug-N-Play device which provides:
•
12
Two NS16C550-compatible UARTs with send/receive 16 byte FIFO
− Support for an IrDA and Consumer IR compliant Infrared interface
Motherboard Description
•
•
•
•
Multi-mode bi-directional parallel port
− Standard mode; IBM† and Centronics† compatible
− Enhanced Parallel Port (EPP) with BIOS/Driver support
− High Speed mode; Extended Capabilities Port (ECP) compatible
Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)
Integrated Real Time Clock with Century calendar functionality
Integrated 8042 compatible keyboard controller
The PC87308 is normally configured automatically by the BIOS, but configuration of these
interfaces also is possible using the CMOS Setup utility that can be invoked during boot. The
serial ports can be enabled as COM1, COM2, COM2 as IrDA, or disabled. The parallel port can
be configured as compatible, bi-directional, EPP/ECP, or disabled. The floppy interface can be
configured for 360 KB or 1.2 MB 5¼ in. media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB
3½ in. media.
1.7.1
Floppy Controller
The PC87308 is software compatible with the DP8473 and 82077 floppy disk controllers. The
floppy interface can be configured for 360 KB or 1.2 MB 5¼" media or for 720 KB, 1.2 MB,
1.44 MB, or 2.88 MB 3½" media in the BIOS setup. By default, the Floppy A interface is
configured for 1.44 MB and Floppy B is disabled. Configuring the floppy interface for 1.2 MB
3½" (3-mode floppy) requires the use of a driver to operate correctly.
1.7.2
Keyboard and Mouse Interface
PS/2† keyboard/mouse connectors are located on the back panel side of the motherboard. The 5V
lines to these connectors are protected with a PolySwitch† circuit which acts much like a selfhealing fuse, re-establishing the connection after an over-current condition is removed. While this
device eliminates the possibility of having to replace a fuse, care should be taken to turn off the
system power before installing or removing a keyboard or mouse.
The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code
which, besides providing traditional keyboard and mouse control functions, supports PowerOn/Reset (POR) password protection. The POR password can be defined by the user via the Setup
program. The keyboard controller also provides for the following “hot key” sequences:
•
•
•
<CTRL> <ALT> <DEL>: System software reset. This sequence performs a software reset of
the system by jumping to the beginning of the BIOS code and running the POST operation.
<CTRL> <ALT> <defined in setup>: Power down and coffee-break key sequences take
advantage of the SMM features of the Pentium Pro processor to greatly reduce the system’s
power consumption while maintaining the responsiveness necessary to service external
interrupts.
<CTRL> <ALT> <defined in setup>: Keyboard secure hot-keys lock the keyboard until user
specified password is given.
13
VS440FX Motherboard Technical Product Specification
1.7.3
Real Time Clock, CMOS RAM and Battery
The integrated Real Time Clock (RTC) is DS1287 and MC146818 compatible and provides a time
of day clock, a 100-year calendar with alarm features, and a century register. The RTC can be set
via the BIOS SETUP program. The RTC also supports 242-byte battery-backed CMOS RAM in
two banks which is reserved for BIOS use. The CMOS RAM can be set to specific values or
cleared to the system default values using the BIOS SETUP program. Also, the CMOS RAM
values can be cleared to the system defaults by using a configuration jumper on the motherboard.
An external coin-cell style battery provides power to the RTC and CMOS memory. The battery
has an estimated lifetime of seven years and is socketed for easy replacement. When the system is
on, the life of the battery is extended by a trickle current from the power supply.
1.7.4
Infrared Support
A 5-pin interface on the front panel I/O connector is provided to allow connection to a Hewlett
Packard HSDSL-1000 compatible Infra-red (IrDA) transmitter/receiver. Once the module is
connected to the front panel I/O header, Serial port 2 can be re-directed to the IrDA module. When
configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s
and printers using application software such as LapLink. The IrDA specification provides for data
transfers at 115kbps from a distance of 1 meter. Support for Consumer Infra Red (ASK-IR and
DASK-IR options for SHARP-IR) is also included.
1.7.5
Parallel port
A 25-pin D-Sub header is provided on the back panel for a multi-mode bi-directional parallel port.
The parallel port operates in standard mode, Enhanced Parallel Port (EPP) version 1.7 mode, with
BIOS and Driver support, and a high speed Extended Capabilities Port (ECP) compatible mode.
EPP Mode requires a driver provided by the peripheral manufacturer to operate correctly.
1.8 Audio Subsystem
The VS440FX motherboard features a 16-bit stereo audio sub-system as a factory installed option.
The audio subsystem is based upon the Crystal CS4232 multimedia codec and Yamaha OPL3 FM
synthesizer. The CS4232 provides all the digital audio and analog mixing functions required for
playing and recording of audio on personal computers. These functions include stereo analog-todigital and digital-to-analog converters, analog mixing, anti-aliasing and reconstruction filters, line
and microphone level inputs, and digital audio compression via selectable A-law / µlaw, and full
digital control of all mixer and volume control functions. Combined with the Yamaha OPL3 FM
synthesizer, the CS4232 also provides support for four major sound standards including Adlib† and
Sound Blaster Pro 2.0, Windows Sound System and MPU-401 to meet all of the requirements of
today’s multimedia applications. The CS4232 also supports full-duplex operation which ensures
support for future applications such as video conferencing.
14
Motherboard Description
The CS4232 includes a full Plug-N-Play ISA interface and is comprised of seven logical devices
including the Synthesizer, Game Port, Sound Blaster, Sound System, MPU-401, CD-ROM and the
CS4232 device itself. Each logical device is configured into the host environment using the ISA
Plug-N-Play configuration methodologies. The audio sub-system requires up to two DMA
channels and one interrupt. The system can be configured to use either DMA channels 0, 1, or 3.
The interrupt and can be mapped to interrupt 5, 7, 9, 11, 12, or 15.

Power Supply Connectors
When used with a power supply that supports remote power on/off, the motherboard can turn off
the system power via software control. The Powerman utility supplied for Windows 3.1x allows
for soft-off as does the shutdown icon in Windows 95 Start menu. The system BIOS will turn the
system power off when it receives the proper APM command from the OS. For example,
Windows 95 will issue this APM command when the user selects “Shutdown the computer”
22
Motherboard Description
option. APM must be enabled in the system BIOS and OS in order for the soft-off feature to work
correctly. The user has the ability to determine the state of the power supply, so if the system was
turned on when power was disconnected, the system will turn back on when power is reapplied or
remain off, depending on the user setup configuration in CMOS.
1.9.13
Front panel Connectors

1.9.13.1
Speaker
The speaker provides error beep code information during the Power-On Self Test, if the system
cannot use the video interface. Jumpering pins 26-27 (the last two pins of J10H1) enables the
onboard speaker. To disable the onboard speaker, remove the jumper from these pins or disable
the on-board speaker via a CMOS setup option.
1.9.13.2
Sleep/Resume
When Advanced Power Management (APM) is activated in the system BIOS and the Operating
System’s APM driver is loaded, Sleep mode (Standby) can be entered in one of three ways: an
optional front panel “Sleep/Resume” button, a user defined keyboard hot key, or prolonged system
inactivity. The Sleep/Resume button is supported by a 2-pin header located on the front panel I/O
connector. Closing the “Sleep” switch will generate an SMI (System Management Interrupt) to the
processor which immediately goes into System Management Mode (SMM).
The front panel “Sleep mode” switch must be a momentary two pin SPST type that is normally
open. The function of the Sleep/Resume button can also be achieved via a keyboard hot-key
sequence, or by a time-out of the system inactivity timer. Both the keyboard hot-key and the
inactivity timer are programmable in the BIOS setup (timer is set to 10 minutes by default). To reactivate the system, or “Resume”, the user must simply press the sleep/resume button again, or use
the keyboard or PS/2 mouse. Mouse activity will only “wake up” the system if a mouse driver is
23
VS440FX Motherboard Technical Product Specification
loaded. While the system is in Standby or “sleep” mode it is fully capable of responding to and
servicing external interrupts (such as in-coming FAX) even though the monitor will only turn on if
a user interrupt (keyboard/mouse) occurs as mentioned above
1.9.13.3
Infra-Red connector
Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once
configured for IrDA, the user can transfer files to or from portable devices such as laptops, PDA’s
and printers using application software such as LapLink. The IrDA specification provides for data
transfers at 115 Kbps from a distance of 1 meter. Consumer IR is also supported by the same
connector.
1.9.13.4
Reset
This 2-pin header can be connected to a momentary SPST type switch that is normally open.
When the switch is closed, the system will hard reset and run POST.
1.9.14
Back Panel Connectors
The back panel provides external access to PS/2 style keyboard and mouse connectors as well as
two serial ports, one parallel port, a MIDI/gameport, and the audio I/O jacks, which are integrated
on the motherboard. Figure 5 shows the general location of the I/O connectors.

Installation Requirements
CAUTION
To avoid an adverse impact on the compliance with safety or regulatory requirements due to
installation of this board assembly, the following guidelines must be followed.
1.14.4.1
Follow Installation Instructions
Be sure to read and adhere to all of these instructions, and the instructions supplied with the host
system and associated modules. If the instructions of the host system appear to be incompatible
with these instructions or the instructions of any associated modules, contact the suppliers’
technical support organization for the products involved to determine the appropriate action for
continued safety and regulatory compliance of the resultant system. Failure to read and follow
instructions provided by host system and module suppliers may result in increased safety risk and
non-compliance with regional laws and regulations.
1.14.4.2
Assure Host System Compatibility
For electromagnetic compatibility, the host system enclosure and power supply should have passed
electromagnetic compatibility testing using a board with a microprocessor from the same family as
the microprocessor on this board, operating at the same or higher microprocessor speed. Also,
only peripherals (computer input/output devices, terminals, printers, etc.) that are CE Marked and
certified by the FCC to comply with Class B limits may be attached to this board. Pay particular
attention to the installation instructions of the host system and other modules, particularly
29
VS440FX Motherboard Technical Product Specification
concerning certifications, external I/O cable shielding and filtering, mounting, grounding and
bonding requirements to assure appropriate shielding effectiveness. Otherwise electromagnetic
compatibility testing must be repeated on a representative sample of the complete system.
For safety, if mismating of connectors could result in a hazard, assure that all connectors are
sufficiently keyed to prevent mismating.
1.14.4.3
Use Only In Intended Applications
This product was evaluated for use in systems installed in offices, homes, schools, computer rooms
or similar applications. Other applications, such as medical, industrial, alarm systems and test
equipment may necessitate a re-evaluation of the product suitability.
1.14.4.4
Assure Host System & Accessory Certifications
Assure that the host system, any other subassemblies such as board & drive assemblies being
added in, and internal or external wiring, are properly certified for the region(s) the end-product
will be used in. Proof of certification can be determined by the marks on the product. For
example:
Europe
The CE Marking signifies compliance with all relevant EU requirements. If the host system 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 achieved by max. 8 Amp current limiting circuit or a max. 5 Amp fuse or Positive
Temperature Coefficient Resistor (PTC). All Intel motherboards presently have PTC’s on all
external ports which provide DC power externally.

Installation Precautions
During installation and initial test, use caution to avoid personal injury and damage to wiring due
to sharp pins on connectors and printed circuit assemblies, rough chassis edges and corners, and
hot components. Adhere to warnings and limitations regarding accessibility into areas designated
only for authorized technical personnel.
1.14.4.6
Battery Marking
There is insufficient space on this board product to provide the required replacement and disposal
instructions for the battery. The following marking must be placed permanently and legibly on the
host system as near as possible to the battery:
CAUTION
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.
1.14.4.7
Overload Protection
Unless the power supply is provided with inherent overcurrent protection, use caution to avoid
overloading the power supply output. This can be accomplished by assuring that the calculated
total current load of all the modules within the system is less than the output current rating of the
power supply. Failure to accomplish this could result in overheating in the power supply, which
could result in a fire or could cause damage to insulation separating hazardous AC line circuitry
from low-voltage user accessible circuitry. If the load drawn by a particular module cannot be
determined by the markings and instructions supplied with the module, contact the module
supplier’s technical support organization.

3 Motherboard BIOS and Setup Utility
3.1 Introduction
The motherboard uses an Intel BIOS, which is stored in Flash EEPROM and easily upgraded using
a floppy disk-based program. In addition to the Intel BIOS, the Flash EEPROM also contains the
Setup utility, Power-On Self Tests (POST), APM 1.1, the PCI auto-configuration utility, and
Windows 95 ready Plug-N-Play 1.0a. This motherboard also supports system BIOS shadowing,
allowing the BIOS to execute from 64-bit on-board write-protected DRAM.
The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit
revision code. The initial production BIOS in the motherboard will be identified as 1.00.01.CS1.
3.2 BIOS Flash Memory Organization
The Intel PA28FB002BX 2 Mb Flash component is organized as 256K x 8 (256 KB). The Flash
device is divided into seven areas, as described in Table 10.

3.3 BIOS Upgrades
Flash memory makes distributing BIOS upgrades easy. A new version of the BIOS can be
installed from a diskette. BIOS upgrades are available to be down loaded from the secure section
on the Intel bulletin board, or Intel’s FTP site.
The disk-based Flash upgrade utility, FMUP.EXE, has three options for BIOS upgrades:
•
•
•
The Flash BIOS can be updated from a file on a disk;
The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the
event that an upgrade cannot be successfully completed; or
The BIOS in the Flash device can be compared with a file to ensure the system has the correct
version.
37
VS440FX Motherboard Technical Product Specification
The upgrade utility ensures the upgrade BIOS extension matches the target system to prevent
accidentally installing a BIOS for a different type of system.
3.4 PCI IDE Support
The two local bus IDE connectors with independent I/O channel support are setup up automatically
by the BIOS if the user selects “Autoconfiguration” in setup. The IDE interface supports PIO
Mode 3, and Mode 4 hard drives and recognition of ATAPI CD-ROMs, tape drives, and any other
ATAPI devices. The BIOS will determine the capabilities of each drive and configure them to
optimize capacity and performance. For the high capacity hard drives typically available today, the
drive will be automatically configured for Logical Block Addressing (LBA) for maximum capacity
and to PIO Mode 3 or 4 depending on the capability of the drive. The user is able to override the
auto-configuration options by using the manual mode setting. The ATAPI Specification Revision
2.5 recommends that an ATAPI device be configured as shown in the table below.

3.5 PCI Auto-configuration
The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow
the insertion and removal of PCI cards to the system without user intervention (Plug-N-Play).
When the system is turned on after adding a PCI add-in card, the BIOS automatically configures
interrupts, I/O space, and other parameters. PCI interrupts are distributed to available ISA
interrupts that have not been assigned to an ISA card, or system resources. Those interrupts left set
to “available” in the CMOS setup will be considered free for PCI add-in card use.
The PCI Auto-Configuration function complies with version 2.10 of the PCI BIOS specification.
System configuration information is stored in ESCD format. The ESCD data may be cleared by
setting the CMOS clear jumper to the ON position.
PCI specification 2.1 for add-in card auto-configuration is also a part of the Plug-N-Play BIOS.
Peer-to-peer hierarchical PCI Bridge 1.0 is supported, and by using an OEM supplied option ROM
or TSR, a PCI-to-PCMCIA bridge capability is possible as well.
38
Motherboard BIOS and Setup Utility
3.6 ISA Plug-N-Play
The BIOS incorporates ISA Plug-N-Play capabilities as delivered by Plug-N-Play Release 1.0A
(Plug-N-Play BIOS V.. 1.0A, ESCD V.. 1.03). When used in conjunction with the ISA
Configuration Utility (ICU) for DOS or Windows 3.x, the system allows auto-configuration of
Plug-N-Play ISA cards, PCI cards, and resource management for legacy ISA cards. Because the
BIOS supports configuring devices across PCI bridges, release 1.41 or greater of the ICU must be
used with the motherboard to properly view and change system settings. System configuration
information is stored in ESCD format. The ESCD data may be cleared by setting the CMOS clear
jumper to the ON position.
The BIOS also has a setup option to support the Windows 95 run time Plug-N-Play utilities. When
this option is selected, only devices critical to booting are assigned resources by the BIOS. Device
Node information is available for all devices to ensure compatibility with Windows 95.
Copies of the IAL Plug-N-Play specification may be obtained via the Intel BBS , or via
CompuServe by typing Go PlugPlay.
3.7 Desktop Management Interface
Desktop Management Interface (DMI) is a method of managing computers in an enterprise. The
main component of DMI is the Management Information Format Database (MIF), which contains
information about the computing system and its components. Using DMI, a system administrator
can obtain the types, capabilities, operational status, installation date and other information about
the system components. The DMI specification requires that certain information about the
system’s motherboard be made available to an applications program. This user-defined
information will be located in a series of data structures which are accessed in various ways by
means of the DMI service layer. Component instrumentation allows the service layer to gain
access to the information stored in the GPNV. The included MIF database defines the data a
provides the method for accessing the information.
The VS440FX BIOS provides the first stage of DMI v. 2.0 support, including static system
configuration information, including motherboard and peripheral data. Future VS440FX product
releases will provide event detection and error logging, achieving the maximum benefit of DMI
with applications such as LANDesk® Client Manager.
3.8 Advanced Power Management
The BIOS has support for Advanced Power Management (APM version 1.1). The energy saving
Stand By mode can be initiated by a keyboard hot key sequence set by the user, a time-out period
set by the user, or by a suspend/resume button tied to the front panel sleep connector.
When in Standby mode, the motherboard reduces power consumption by utilizing the Pentium Pro
processor’s System Management Mode (SMM) capabilities and also spinning down hard drives
and turning off VESA DPMS compliant monitors. The user may select which DPMS mode
(Standby, Suspend, or Off) send to the monitor in setup. The ability to respond to external
interrupts is fully maintained while in Standby mode allowing the system to service requests such
39
VS440FX Motherboard Technical Product Specification
as an in-coming fax or network message while unattended. Any keyboard or mouse activity brings
the system out of the energy saving Standby mode. When this occurs the monitor and IDE drives
are turned back on immediately.
APM is enabled in BIOS by default, however, the system must be configured with an APM driver
in order for the system power saving features to take effect. Windows 95 will enable APM
automatically upon detecting the presence of the APM BIOS.
3.9 Advanced Power Control
The BIOS supports Advanced Power Control (APC) through the National 308 Super I/O controller.
Two features that have been implemented are Auto Start On AC Loss and Power-On COM1 Ring.
Auto Start On AC Loss sets the control for returning to the last known state of the system, or
powering down upon AC power loss to the motherboard. Power-On COM1 Ring sets the control
for allowing the system to be powered on upon an incoming POTS call to a telephony device
configured for operation on COM1.
3.10 Language Support
The BIOS setup screen and help messages are supported in 32 languages. There are 5 languages
available at this time: American English, German, Italian, French, and Spanish. Translation to
other languages may become available at a later date.
3.11 Boot Options
Booting from CD-ROM is supported in adherence to the “El Torito” v. 1.0 bootable CD-ROM
format specification developed by Phoenix Technologies and IBM. Under the Boot Options field
in setup, CD-ROM is one of four possible boot devices which are defined in priority order. The
default setting is for floppy to be the primary boot device and hard drive to be the secondary boot
device. If CD-ROM is selected, it must be the first device. The third and fourth devices are set to
disabled in the default configuration. The user can add also select network as a boot device. The
network option allows booting from a network add-in card with a remote boot ROM installed.
✏
NOTE
A copy of “El Torito” v. 1.0 is available on the Phoenix Web page
(http://www.ptltd.com/techs/specs.html).
3.12 Flash LOGO Area
The motherboard supports a 4 KB programmable flash user area located at E8000-E8FFF. An
OEM may use this area to display a custom logo. The BIOS accesses the user area just after
completing POST. A utility is available from Intel to assist with installing a logo into flash for
display during POST. Contact your local Intel Sales office or authorized distributor for further
information.
40
Motherboard BIOS and Setup Utility
3.13 Setup Enable Jumper
A motherboard configuration jumper controls access to the BIOS Setup utility. By setting the
jumper to the disable position, the user is prevented from accessing the Setup utility during the
Power-On Self Test or at any other time. The message prompting the user to press <F1> to enter
setup is also disabled.
3.14 Overview of the Setup Menu Screens
The Setup program initially displays the Main menu screen. In each screen there are options for
modifying the system configuration. Select a menu screen by pressing the left <←> or right <→>
arrow keys. Use the up <↑> or down <↓> arrow keys to select items in a screen. Use the <Enter>
key to select an item for modification. For certain items, pressing <Enter> will bring up a

Shadowing is a technique that copies a block of memory from an add-in card’s ROM to the same
address in system memory. This provides faster access and achieves higher performance. By
default, all upper memory is shadowed.
50
Motherboard BIOS and Setup Utility
3.14.9.4
ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are C8000h, CC000h, D0000h,
D4000h, D8000h, and DC000h. The default is C8000h. This setting could affect the ISA Shared
Memory Size item. The value entered in the ISA Shared Memory Size item cannot extend to the
E0000h address. For example, if a size of 64K was selected, options D4000h, D8000h, and
DC000h will not be available.
3.14.9.5
IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15
Sets the status of the IRQ. The options are Available and Used By ISA Card. The default is
Available. The PCI auto-configuration code looks here to see if these interrupts are available for
use by a PCI add-in board. If an interrupt is available, the PCI auto-configuration code can assign
the interrupt to be used by the system. If your system contains an ISA agent that uses one of these
interrupts, select Used By ISA Card for that interrupt.
✏
NOTE
IRQ 3, 4, 5, and 7 may not be available in this option, depending on the setting chosen for the
COM1, COM2 and parallel ports in the Peripheral Configuration Subscreen. IRQ 14 and 15 may
not be available if the Primary and Secondary IDE ports are enabled.
3.14.10
Security Screen
This section describes the two access modes that can be set using the options found on the Security
screen, and then describes the Security screen options themselves.
3.14.10.1
Administrative and User Access Modes
The options on the Security screen menu make it possible to restrict access to the Setup program
by enabling you to set passwords for two different access modes: Administrative mode and User
mode.
In general, Administrative mode has full access to the Setup options, whereas User mode has
restricted access to the options. Thus, by setting separate Administrative and User passwords, a
system administrator can limit who can change critical Setup values. The actual limitations depend
on whether either the Administrative or User passwords or both are set. (See the table below for a
description of how the passwords actually work together.)
To limit access to who can boot the system, set the User password. This is the password that the
system asks for before booting. If only the Administrative password is set, the system boots up
without asking for a password. If both passwords are set, you can enter either password to boot the
system.
The following table shows the effects of setting the Administrative and User passwords. (The table
is for reference only, and is not shown on the Security screen.) In the table, the statement “Can
change a limited number of options” means you can change the system date and time, the power
management hot key, the User password, the security hot key, and unattended start.
