Motherboard Description
1.5 Microprocessor
The motherboard operates with 2.1 V to 3.5 V Pentium Pro processors. The onboard voltage
regulator is automatically programmed and controlled by the VID pins of the processor to provide
the required voltage. The motherboard supports Pentium Pro processors that run internally from
150 MHz up to 200 MHz.
The motherboard supports Pentium Pro processors with either 256 KB or 512 KB of second-level
cache.
TM
TM
The processor maintains full backward compatibility with the 8086, 80286, Intel386 , Intel486 ,
and Pentium processors. Its numeric coprocessor maintains backward compatibility with math
coprocessors and that comply with ANSI/IEEE standard 754-1985.
1.5.1
Microprocessor Heatsink and Clips
CAUTION
Do not use the older style of bail-wire clips for securing the heat sink assembly. These clips have
been known to damage the motherboard when installed or removed incorrectly.
An approved Pentium Pro processor heat sink is necessary for proper thermal dissipation. The
processor/heat sink assembly must be securely fastened to the ZIF socket by two clips. These clips
fit over the heat sink assembly and attach to tabs on the socket.
1.5.2
Microprocessor Upgrade
The motherboard has a Socket 8 processor socket. Socket 8 is a 387-pin modified staggered pin
grid array (SPGA) ZIF socket with a voltage regulator for the processor core. The socket supports
upgrades to future Pentium Pro OverDrive® processors.
11
VS440FX Motherboard Technical Product Specification
1.6 Main Memory
The motherboard has four SIMM sockets arranged in two banks: Bank 0 and Bank 1. Each bank
has two sockets. SIMMs in the same bank must be the same type, size, and speed; SIMMs in
different banks may differ in type, size, and speed. SIMMs must be installed in both sockets of a
bank, and at least one bank must be filled. The BIOS automatically detects memory type and size
so no jumper settings are required.
The motherboard supports:
•
•
•
•
1.6.1
72-pin SIMMs with tin-plated contacts
60 ns fast page mode SIMMs or 60 ns EDO SIMMs
Non-parity, parity, or ECC SIMMs
Single- or double-sided SIMMs in the following sizes:
SIMM size
Configuration Configuration
(non-parity)
(parity)
4 MB
1 x 32
8 MB
2 x 32
2 x 36
16 MB
4 x 32
4 x 36
32 MB
8 x 32
8 x 36
64 MB
16 x 32
16 x 36
1 x 36
EDO DRAM
EDO DRAM improves memory read performance by holding the memory data valid until the next
CAS# falling edge, unlike fast page mode DRAM, which tri-states the memory data when CAS#
negates to precharge for the next memory cycle. With EDO DRAM, the CAS# precharge overlaps
the data-valid time, which allows CAS# to negate earlier while still satisfying the memory-data
valid window.
1.6.2
Parity/ECC DRAM
Memory error checking and correction is supported by parity memory. With parity memory, the
motherboard can be configured to support ECC memory operation. Parity SIMMs are
automatically detected, but you must enter Setup to configure the memory for either Parity or ECC
operation. Parity memory detects single-bit errors. ECC memory detects double-bit errors and
corrects single-bit errors.
12

Support for full speed (12 Mbs) and low speed (1.5 Mbs) USB connections. Full speed
connections require shielded cabling.
Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications.
Error handling and fault recovery mechanisms built into protocol.
IDE Support
The motherboard has two independent bus mastering PCI IDE interfaces that support PIO Mode 3,
PIO Mode 4, and ATAPI (e.g., CD-ROM) devices. The BIOS supports Logical Block Addressing
(LBA) and Extended Cylinder Head Sector (ECHS) translation modes. IDE device transfer rate
and translation mode are automatically detected by the BIOS.
Normally, programmed I/O operations require a substantial amount of processor bandwidth;
however, in true multi-tasking operating systems such as Windows† 95, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.

15
VS440FX Motherboard Technical Product Specification
1.8.4
Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel of the motherboard. The 5 volt
lines to these connectors are protected with a PolySwitch† circuit that, like a self-healing fuse,
reestablishes the connection after an over-current condition is removed. While this device
eliminates the possibility of having to replace a fuse, power to the computer should be turned off
before connecting or disconnecting a keyboard or mouse.
✏
NOTE
You can plug the mouse and keyboard into either connector.
The keyboard controller contains the AMI Megakey keyboard and mouse controller code, which
provides the traditional keyboard and mouse control functions, and also supports Power On/Reset
password protection. A Power On/Reset password can be specified in the Setup program.
The keyboard controller also supports the following hot-key sequences:
•
•
•
•
1.8.5
<CTRL><ALT><DEL> Software reset. This key sequence resets the computer’s software by
jumping to the beginning of the BIOS code and running the Power On Self Test (POST).
<CTRL><ALT><+> and <CTRL><ALT><-> Turbo mode. Note that Turbo mode could be
affected by the operating system, or whether the processor is in protected mode or virtual
x86 mode.
 <CTRL><ALT><-> For Deturbo mode (emulates a 23 MHz AT)
 <CTRL><ALT><+> For Turbo mode
<CTRL><ALT><defined in Setup> Power management. This key sequence invokes power
managed mode, which reduces the computer’s power consumption while maintaining its ability
to service external interrupts.
<CTRL><ALT><defined in Setup> Keyboard lock. This key sequence is a security feature
that locks the keyboard until the User password is entered. When keyboard lock is invoked,
the keyboard LEDs flash. To enable the keyboard lock feature, a User password must be
specified in the Setup program.
Real-Time Clock, CMOS RAM, and Battery
The real-time clock is compatible with DS1287 and MC146818 components. It provides a timeof-day clock and a 100-year calendar with alarm features and century rollover. The real-time clock
also supports 242-bytes of battery-backed CMOS RAM in two banks, which are reserved for
BIOS use.
The time, date, and CMOS values can be specified in the Setup program. The CMOS values can
be returned to their defaults by using the Setup program or by setting a configuration jumper on the
motherboard.
An external coin-cell battery powers the real-time clock and CMOS memory. If the computer is
not plugged into a wall socket, the battery has an estimated life of three years. When the computer
is plugged in, the 5 volt standby current from the motherboard’s power supply extends the life of
the battery. The RTC is accurate to ±13 minutes/year at 25 ºC and 5 V conditions.

Signal names in brackets are for the secondary IDE connector
Power Supply Connector (J5M1)
An ATX power supply supports remote power on/off through pin 14 of the power supply
connector. This enables the motherboard to turn off system power through software control.
To enable soft-off control in software, APM must be enabled in the Setup program and in the
operating system. When the system BIOS receives the correct APM command from the operating
system, the BIOS turns off power to the computer. For example, in the Windows 95 Start menu,
the user selects Shutdown to turn off the power.
23
VS440FX Motherboard Technical Product Specification
With soft-off enabled, if power to the computer is interrupted by a power outage or a disconnected
power cord, when power resumes the computer returns to the on or off state it was in before power
was interrupted.

Power On Connector
You must connect this header to a power switch that could be placed on the front panel. A
momentary ground must be applied to the SW_ON pin to signal the supply to turn on or off. This
requirement is usually satisfied by using a SPST normally open momentary contact switch.
Because of the motherboard’s internal debounce circuitry, the ground must be applied for at least
50 ms. To prevent double-clicking, at least 2 seconds must pass before the power supply will
recognize another on/off signal.
1.11.9.3
Sleep/Resume
When APM is enabled in the system BIOS and the operating system’s APM driver is loaded, the
system can enter Sleep (Standby) mode in one of three ways:
•
•
•
Optional front panel Sleep/Resume button
Hot key defined in the BIOS Setup program
Prolonged system inactivity; the default timeout is 10 minutes and can be changed in Setup
A Sleep/Resume button is supported by the 2-pin header located on the front panel I/O connector.
The front panel Sleep/Resume switch must be a momentary SPST type that is normally open.
Closing the Sleep/Resume switch generates a System Management Interrupt (SMI) to the
processor, which immediately goes into System Management Mode (SMM). While the system is
in Sleep mode it is fully capable of responding to and servicing external interrupts (such as an
incoming fax) even though the monitor turns on only if a keyboard or mouse interrupt occurs. To
reactivate the system you must press the Sleep/Resume button again, or use the keyboard or
mouse.
26
Motherboard Description
1.11.9.4
Infrared Connector
You can connect an IrDA module to a 6-pin header on the motherboard. After configuring the
IrDA interface, you can transfer files to or from portable devices such as laptops, PDAs, and
printers using application software.
1.11.9.5
Hard Drive (HD) LED
You can connect this header to an LED to provide a visual indicator that data is being read from or
written to an IDE hard drive. For the LED to function properly, the IDE drive must be connected
to the onboard IDE controller on the motherboard.
1.11.9.6
Sleep/Power LED
You can connect this header to an LED that will light when the computer is powered on. This
LED will also blink when the computer is in a power-managed state.
1.11.9.7
Reset
You can connect this header to a momentary SPST type switch that is normally open. When the
switch is closed, the board resets and runs the POST.
1.11.9.8
Speaker
A speaker may be installed on the motherboard as a manufacturing option. The speaker option
includes a jumper on pins 26-27 of the front panel connector. You can disable the onboard speaker
by removing the jumper, and you can connect an offboard speaker in its place. The speaker
(onboard or offboard) provides error beep code information during the POST in the event that the
computer cannot use the video interface. The speaker is not connected to the audio subsystem, and
does not receive output from the audio subsystem.

3 BIOS and Setup Utility
3.1 Introduction
The motherboard uses an Intel BIOS, which is stored in Flash EEPROM and can be
upgraded using a floppy disk-based program. In addition to the BIOS, the Flash EEPROM
contains the Setup utility, POST, APM, the PCI auto-configuration utility, and Windows 95-ready
Plug and Play.
This motherboard supports system BIOS shadowing, allowing the BIOS to execute from 64-bit
onboard 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 is identified as 1.00.01.CS1.
Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS
Technical Reference published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical
Reference published by AMI. Both manuals are available at most technical bookstores.
3.2 BIOS Flash Memory Organization
The Intel PA28FB200BX 2 Mbit Flash component is organized as 256K x 8 (256 KB). The Flash
device is divided into eight areas, as described in Table 13.

VS440FX Motherboard Technical Product Specification
3.3 BIOS Upgrades
Flash memory simplifies distributing BIOS upgrades. You can install a new version of the BIOS
from a diskette. BIOS upgrades are available to be downloaded from the secure section on the
Intel bulletin board or from Intel’s FTP or World Wide Web sites (refer to Section 5.2).
The disk-based Flash upgrade utility, FMUP.EXE, has three options for BIOS upgrades:
•
•
•
Update the Flash BIOS from a file on a disk
Copy the current BIOS code from the Flash EEPROM to a disk file as a backup, in the event
that an upgrade cannot be successfully completed
Compare the BIOS in the Flash device with a file to make sure the system has the correct
version
The upgrade utility ensures that 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
If you select “Autoconfiguration” in Setup, the BIOS automatically sets up the two local bus IDE
connectors with independent I/O channel support. The IDE interface supports PIO Mode 3 and
Mode 4 hard drives and recognizes any ATAPI devices, including CD-ROM drives and tape
drives. The BIOS determines the capabilities of each drive and configures them to optimize
capacity and performance. To take advantage of the high capacities typically available today, hard
drives are automatically configured for LBA and to PIO Mode 3 or 4, depending on the capability
of the drive. You can override the auto-configuration options by specifying manual configuration
in Setup. The ATAPI Specification recommends that ATAPI devices be configured as shown in
Table 14.

BIOS and Setup Utility
3.5 PCI Auto-configuration
The PCI auto-configuration utility operates in conjunction with the Setup utility to let you insert
and remove PCI cards without user configuration (Plug and Play). When you turn on the system
after adding a PCI card, the BIOS automatically configures interrupts, I/O space, and other
parameters. PCI interrupts are distributed to available ISA interrupts that have been not been
assigned to an ISA card or to system resources. Any interrupts set to “available” in Setup are
considered free for use by PCI add-in cards. The assignment of PCI interrupts to ISA IRQs is
nondeterministic.
System configuration information is stored in ESCD format. You can clear the ESCD data by
moving the Clear CMOS jumper (refer to Section 1.13.3).
For information about the version of PCI supported by this BIOS, refer to Section 5.1. Peer-topeer hierarchical PCI Bridge is supported, and by using an OEM-supplied option ROM or TSR, a
PCI-to-PCMCIA bridge capability is possible as well.
3.6 ISA Plug and Play
The BIOS incorporates ISA Plug and Play capabilities. When used in conjunction with the ISA
Configuration Utility (ICU) for DOS or Windows 3.x, the system allows auto-configuration of
Plug and Play ISA cards or PCI cards, and manages resource for legacy ISA cards. Because the
BIOS supports configuring devices across PCI bridges, you must use ICU release 1.41 or greater to
properly view and change system settings.
System configuration information is stored in ESCD format. You can clear the ESCD data by
moving the Clear CMOS jumper (refer to Section 1.13.3).
There is a Setup option to support Windows 95 runtime Plug and Play utilities. If you select this
option, the BIOS assigns resources only to devices that are critical to booting. Device Node
information is available for all devices to ensure compatibility with Windows 95.
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 (MIF) database, which contains
information about the computing system and its components. Using DMI, a system administrator
can obtain the system 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 information is located in
a series of data structures which are accessed in various ways by the DMI service layer.
Component instrumentation allows the service layer to gain access to information stored in the
general-purpose area of non-volatile memory. The MIF database defines the data and provides the
method for accessing the information.
45
VS440FX Motherboard Technical Product Specification
The BIOS support for DMI enables the maximum benefit from applications such as LANDesk
Client Manager from Intel. The BIOS stores and can report on the following types of DMI
information:
•
•
•
•
BIOS data, such as the BIOS revision level
Fixed system information, such as data about the motherboard, peripherals, serial numbers and
asset tags, etc.
System information discovered during bootup, such as memory size, cache size, processor
speed, etc.
Dynamic information, such as event detection and error logging
An OEM can use a utility that makes DMI calls to program system and chassis-related information
into the Flash memory, so the BIOS can also report that information. Once this information is
written, it is locked (read-only).
Intel can provide a utility for making DMI calls to the BIOS. Contact your local Intel Sales office
for further information. The latest DMI specification is available from Intel (refer to Section 5.2)
and other sites.
DMI does not work directly under non-Plug and Play operating systems (e.g., Windows NT).
However, the BIOS supports a DMI table interface for such OSs. Using this support, a DMI
service-level application running on a non-Plug and Play OS can access the DMI BIOS
information.
3.8 Advanced Power Management
The BIOS supports APM. You can initiate the energy saving Standby mode in these ways:
•
•
•
Keyboard hot key sequence specified in Setup
Time-out period specified in Setup
Suspend/resume switch connected to the front panel sleep connector
When in Standby mode, the motherboard reduces power consumption by using the processor’s
System Management Mode (SMM) capabilities and by spinning down hard drives and reducing
power to or turning off VESA† DPMS-compliant monitors. In Setup you can select the DPMS
mode to use for the monitor: Standby, Suspend, Sleep, or Disabled (Off).
While in Standby mode, the system retains the ability to respond to external interrupts; it can
service requests such as incoming faxes or network messages while unattended. Any keyboard or
mouse activity brings the system out of Standby mode and immediately restores power to the
monitor and IDE drives.
APM is enabled in the BIOS by default; however, the system must be configured with an APM
driver for the power-saving features to take effect. For example, Windows 95 enables APM
automatically upon detecting the presence of the APM BIOS.
46
BIOS and Setup Utility
3.9 Advanced Power Control
The BIOS supports Advanced Power Control (APC) through the Super I/O controller. Two
features include:
•

3.10 Language Support
The BIOS Setup utility and help messages are supported in 32 languages. Five languages are
available at this time for use: American English, German, Italian, French, and Spanish.
Translations of other languages may become available at a later date.
With a 2 Mb Flash BIOS, only two languages can be resident at a time. The default language is
American English, which is always present unless another language is programmed into the BIOS
using the Flash Memory Update Program (FMUP.EXE). Refer to Section 5.2 for information
about downloading FMUP and other utilities.
3.11 Boot Options
Booting from CD-ROM is supported in adherence to the “El Torito” 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 the floppy drive to be the primary boot device and the hard drive to be the
secondary boot device. (By default the third and fourth devices are disabled.) If you select
CD-ROM as the boot device, it must be the first device.
✏
NOTE
A copy of “El Torito” is available on the Phoenix Web site http://www.ptltd.com/techs/specs.html.
In Setup you can also select the network as a boot device, which allows booting from a network
add-in card with a remote boot ROM installed.
3.12 Flash LOGO Area
The motherboard supports a 4 KB programmable Flash user area located at E8000-E8FFF. You
can use this area to display a custom OEM 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 for further information.

3.13 BIOS Setup Access Jumper
You can move the Setup Access jumper on the motherboard to enable or disable access to the
Setup utility. The default is for access to be enabled. Refer to Section 1.13.4 for the specific pins
on which to place the jumper.
3.14 Recovering BIOS Data
Some types of failure can destroy the BIOS data. For example, the data could be lost if a power
outage occurs while your are updating the BIOS in Flash memory. You can recover the BIOS data
from a diskette by changing the setting of the BIOS Recover jumper (refer to Section 1.13.5). To
recover the BIOS:
1. Turn off the computer and move the jumper to the BIOS recovery setting.
2. In drive A, insert the supplied boot disk containing the BIOS files and Recovery file.
3. Boot the computer. The system should beep once and drive activity should start. When
recovery is successful, the system beeps twice and drive activity stops.
After recovery, turn off the computer and return the jumper to the original pins to restore normal
operation.
3.15 BIOS Setup Utility
The Setup utility lets you modify the configuration for most basic changes without opening the
system. Setup is accessible only during the POST. To enter Setup, press the <F1> key after the
POST memory test has begun and before boot begins. By default, there is a prompt to press the
<F1> key to access Setup, but this prompt may be disabled. Refer to Section 1.13.4 for
information on placing the jumper that prevents user access to Setup for security purposes.
3.15.1
Overview of the Setup Menu Screens

61
VS440FX Motherboard Technical Product Specification
By default, upper memory is allocated as follows: Memory from C0000-C7FFF is automatically
shadowed (this memory range is typically reserved for video BIOS). Memory from C8000-DFFFF
is initially unshadowed. The BIOS scans this range for any ISA add-in cards that may be present
and notes their location and size. The BIOS then auto-configures the PCI devices and Plug and
Play devices, shadowing their ROM requirements (other than video) into the area above E0000. If
that area becomes full, the BIOS continues shadowing to the area between C8000 and DFFFF. If
an ISA legacy card has non-ROM memory requirements, the auto-configure routine might write
into an area that is needed by the ISA card. Use the ISA Shared Memory Size and ISA Shared
Memory Base Address fields to reserve a block of memory that will not be used for shadowing.
3.15.10.4
ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are:
•
•
•
•
•
•
C8000h (default)

D4000h
D8000h
DC000h
The options that appear depend on the ISA Shared Memory Size field. The total amount of ISA
Shared Memory cannot extend to the E0000h address. For example, if you specify a size of
64 KB, options D4000h, D8000h, and DC000h will not be available.
3.15.10.5
IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15
Sets the status of the IRQ. The options are:
•
•
Available (default)
Used By ISA Card
The PCI auto-configuration code uses these settings to determine whether these interrupts are
available for use by PCI add-in cards. If an interrupt is marked available, the auto-configuration
code can assign the interrupt to be used by the system. If your computer has an ISA add-in card
that requires an interrupt, select Used By ISA Card for that interrupt.
✏
NOTE
IRQs 5, 9, 10, 11, and 12 are the default user-available IRQs. Depending on the configuration of
your system, other IRQs may be listed (for example, if you disable the parallel port and/or serial
ports).

Security Screen
This section describes the passwords you can set to restrict access to the Setup program and to
restrict who can boot the computer.
3.15.12.1
Administrative and User Access Modes
The options on the Security screen let you set a User password and/or an Administrative password.
The access restrictions for the User and Administrative modes are:
•
•
Setup options: The Administrative password gives you full access to Setup options; the User
password can be limited to only certain 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 one or both passwords are set. Table 16 shows how the
passwords work together.
Booting the system: 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.
Table 16 shows the effects of setting the Administrative and User passwords. The table is for
reference only, and is not shown on the Security screen.
