Figure 3. Back Panel I/O Shield (with Audio option) Dimensions

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.

The processor maintains full backward compatibility with the 8086, 80286, Intel386 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.

, Intel486TM,

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.

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:

• 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:

Configuration

SIMM size

4 MB 1 x 32 1 x 36 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

(non-parity)

Configuration (parity)

1.6.1 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.

Motherboard Description

1.7 Chipset

The Intel 82440FX PCIset consists of the 82441FX PCI Bridge and Memory Controller (PMC), the 82442FX Data Bus Accelerator (DBX), and one 82371SB PCI/ISA IDE Xcelerator (PIIX3) bridge chip.

1.7.1 82441FX PCI Bridge and Memory Controller (PMC)

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:

• <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.

1.11.6 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.

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.

1.11.9.2 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.

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.

1.11.10 Back Panel Connectors

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.

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.

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 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.

DPMS-compliant monitors. In Setup you can select the DPMS

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:

• Auto Start On AC Loss, which sets the control for returning to the last known state of the

system or powering down the system if the motherboard detects that the power supply has lost AC power.

• Power-On COM1 Ring, which sets the control that allows the system to be powered on when

an incoming POTS call is received on a telephony device configured for operation on COM1.

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.

VS440FX Motherboard Technical Product Specification

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

Table 15 lists the screens displayed by the Setup utility. Setup 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> brings up a subscreen. After you have selected an item, use the arrow keys to modify the setting.

3.15.10 Plug and Play Configuration Subscreen

This section describes the options in the Plug and Play configuration subscreen.

3.15.10.1 Configuration Mode

Sets how the BIOS gets information about ISA cards that do not have Plug and Play capabilities. The options are:

• Use Setup Utility (default)

• Use ICU (The BIOS will depend on run-time software to prevent conflicts between add-in

cards with Plug and Play capabilities and those without. Boot with PnP OS will be the only field that appears on this subscreen.)

3.15.10.2 Boot with PnP OS

Lets the computer boot with an operating system capable of managing Plug and Play add-in cards. The options are:

• None

• Other

• Windows 95 (default)

3.15.10.3 ISA Shared Memory Size

Lets you specify a range of memory addresses that will be usable by ISA add-in cards for shared memory, and that will not be used for shadowing ROM memory from other devices. The options are:

• Disabled (the ISA Shared Memory Base Address field does not appear) (default)

• 16 KB

• 32 KB

• 48 KB

• 64 KB

• 80 KB

• 96 KB

Enable this field only if you are using a legacy ISA add-in card without Plug and Play capabilities, and the card requires non-ROM memory space. For example, this could include LAN cards that have onboard memory buffers or video capture cards that have video buffer memory.

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)

• CC000h

• D0000h

• 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).

3.15.11 Event Logging Configuration Subscreen

This section describes the options available in the Event Logging Configuration subscreen.

3.15.11.1 Event Log Status

This information field tells whether the log is full or not. There are no options.

• Yes

3.15.11.6 Mark Existing Events Read

Marks or does not mark all events already in the log as having been read. The options are:

• No (default)

• Yes

3.15.12 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.
