Microprocessor

The VS440FX motherboard is designed to operate with 150 MHz or faster Intel Pentium Pro processors.  The Pentium Pro microprocessor, in addition to its expanded data and addressing capabilities, includes the following features:

•	Next generation Pentium Pro OverDrive® processor ready, including a zero insertion force Socket 8

•	Backward compatibility with Intel microprocessor architecture

•	Onchip numeric coprocessor (compatible with the Pentium processor and compliant with ANSI/IEEE standard 754-1985)

•	Onchip 16 KB L1 cache (8KB for data, 8 KB for code)

•	256 KB or 512 KB L2 cache in the same module as the microprocessor

Chapter 3 tells how to upgrade the microprocessor.


Memory

The motherboard supports base (conventional) and extended memory.  Operating systems such as MSDOS†, OS/2†, UNIX†, and all application programs use base memory.  For better performance, OS/2 and UNIX as well as many MS-DOS applications use extended memory.  For the main memory map, see Chapter 5.

The motherboard supports up to 256 MB of DRAM.  DRAM is implemented through 72-pin single in-line memory modules (SIMMs).  The motherboard contains four SIMM sockets.  Chapter 3 describes how much memory and  which type of SIMM you can install to get the total amount of DRAM you want.


Error Checking and Correction

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 multi-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.


Cache Memory

The Pentium Pro microprocessor includes 16 KB of L1 cache on the chip.  A 256 KB or 512 KB secondary (L2) cache device is contained in the same package as the microprocessor.


IDE Peripheral Interface

The motherboard provides a high speed, 32-bit PCI/IDE interface.  The PCI/IDE interface supports:

•	Up to four PCI/IDE hard drives on the PCI bus

•	PIO Mode 3 and Mode 4 support

•	Logical block addressing (LBA) of hard drives larger than 528 MB

•	Extended Cylinder Head Sector (ECHS) translation modes

•	ATAPI devices (such as CD-ROMs) on both IDE interfaces


I/O Features

The Super I/O controller (PC87308) integrates the functions for the serial ports, parallel port, diskette drive, and keyboard.  This component provides:

•	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 RS-232C 116550A-compatible 9-pin serial ports.

•	Integrated real time clock with an accuracy of ±13 minutes/year.

•	A 242-byte battery-backed CMOS RAM.

•	Integrated 8042 compatible keyboard controller.

•	Flexible IRQ and DMA mapping to support Windows† 95.

•	Support for an IrDA† or Consumer IR compatible infrared interface.  The infrared interface supports data transfer rates of up to 115 K baud with either half- or full-duplex operation.  In full-duplex mode, both the transmitter and receiver are enabled simultaneously for higher throughput.

•	Industry standard diskette drive controller that supports 720 KB, 1.44 MB, and 2.88 MB 3.5-inch drives (at 135 tracks per inch); and 360 KB and 1.2 MB 5.25-inch drives.


BIOS Features

The BIOS, from American Megatrends Incorporated (AMI), provides ISA and PCI compatibility.  The BIOS is contained in a flash memory device.  The BIOS provides the power-on self test (POST), the Setup program, a PCI and IDE auto-configuration utility, and BIOS recovery code.

The BIOS is always shadowed.  Shadowing allows any BIOS routines to be executed from fast 32-bit onboard DRAM instead of from the slower 8-bit flash device.


PCI Auto-configuration

The PCI auto-configuration utility works in conjunction with the Setup program to support using PCI add-in boards in the computer.  When you turn on the power after installing a PCI board, the BIOS automatically configures interrupts, DMA channels, I/O space, and so on.  Since PCI add-in boards use the same interrupt resources as ISA add-in boards, you must specify the interrupts used by ISA boards in the Setup program.  Chapter 2 tells how to use the Setup program.  The PCI auto-configuration program complies with version 2.1 of the PCI BIOS specification.


IDE Auto-configuration

If you install an IDE drive in the computer, the IDE auto-configuration utility automatically detects and configures the drive for operation.  This utility eliminates the need to enter the Setup program after you install an IDE drive.


ISA Plug-N-Play Capability

This provides auto-configuration of Plug-N-Play ISA cards and resource management for legacy (non Plug-N-Play) ISA cards when used with the ISA Configuration Utility (ICU) or a Plug-N-Play compatible operating system like Windows 95.


BIOS Upgrades

Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS without having to disassemble the computer.  The flash upgrade process can be done by running a utility from a diskette or hard disk, or over a network.

For information about the latest BIOS update, contact your service representative.


Expansion Slots

The board has three dedicated 16-bit ISA/AT†compatible and three dedicated PCIcompatible expansion slots.  One expansion slot is a "combination" slot and can be used by either a PCI or an ISA board, allowing you to install a maximum of seven add-in boards.


Security Features

The BIOS provides a password option that you can enable through the Setup program (see Chapter 2).


Keyboard/Mouse Controller

The I/O controller stores the keyboard and mouse controller code.  The board uses PS/2-style connectors for the keyboard and mouse.


Real-Time Clock and CMOS RAM

The I/O controller provides a real-time clock and CMOS RAM.  Chapter 3 provides information about replacing the battery.

You can set the time for the clock and the CMOS values by using the Setup program, described in Chapter 2.


Fan Connectors

The board contains connectors for a microprocessor fan and an auxiliary fan.  Refer to Chapter 5 for the locations and pinouts of the fan connectors.


Speaker

A speaker is mounted on the board.  The speaker provides audible error code information (beep codes) during the power-on self test (POST) if the BIOS cannot use the video interface.  See Chapter 4 for beep code information.

•	NOTE

The board also has a connector for an offboard speaker.  If you install an offboard speaker, remove the jumper that enables the onboard speaker (Chapter 5).


Using the Setup Program

This chapter tells how to use the Setup program that is built into the BIOS.  The Setup program makes it possible to change configuration information (such as the types of peripherals that are installed) and the boot-up sequence for the computer.  The Setup information is stored in CMOS random access memory (RAM) and is backed up by a battery when power is off.

If the board does not operate as described here, see Chapter 4 for problem descriptions and error messages.

To go into the Setup program, reboot the board and press <F1> as soon as you see the message “Press <F1> Key if you want to run SETUP.”  You have about five seconds to press <F1> to enter Setup before the boot process continues.


Record the Setup Configuration

To make sure you have a reference to the Setup values for your computer, we recommend you write down the current settings and keep this record up-to-date.


Setup Menu Overview

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 an add-in board.  If your computer 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 field, depending on the setting chosen for the COM1, COM2 and parallel ports in the Peripheral Configuration Subscreen.


Security Screen

This section describes the two access modes that can be set using the fields found on the Security screen, and then describes the Security screen fields themselves.

Administrative and User Access Modes

The fields 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 fields, whereas User mode has restricted access to the fields.  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 computer, set the User password.  This is the password that the BIOS asks for before booting.  If only the Administrative password is set, the computer boots up without asking for a password.  If both passwords are set, you can enter either password to boot the computer.

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 fields” means you can change the System Date, System Time, the Power Management Hot Key, the User Password, the Security Hot Key, and Unattended Start.

Table 1.	Administrative and User Password Functions

Password  Set	Administrative mode	User mode	Password required during  boot
Neither	Can change all fields*	Can change all fields*	None
Administrative  only	Can change all fields	Can change a limited number of fields	None
User only	N/A	Can change all fields	User
Both	Can change all fields	Can change a limited number of fields	Administrative or User
* If no password is set, any user can change all Setup fields.


Security Screen Options

User Password is

Reports if there is a User password set.  There are no options.

Administrative Password is

Reports if there is an Administrative password set.  There are no options.

Set User Password

Sets the User password.  The password can be up to seven alphanumeric characters.

Set Administrative Password

Sets the Administrative password.  The password can be up to seven alphanumeric characters.

Unattended Start

Controls when the security password is requested.  The options are Enabled and Disabled.  The default is Disabled.  The User password must be enabled before you can enable this field.  If Enabled is selected, the computer boots, but the keyboard will be locked until the User password is entered.

Security Hot Key (CTRL-ALT-)

Sets a hot key that, when pressed, locks the keyboard until the User password is entered.  The Keyboard LED's flash to indicate that the keyboard is locked.  When you enter the User password, you do not have to press the <Enter> key.


Exit Screen

This section describes the different ways to exit and save or not save changes made in the Setup program.

Exit Saving Changes

Saves the changes to CMOS RAM and exits the Setup program.  You can also press the <F10> key anywhere in the Setup program to do this.

Exit Discarding Changes

Exits the Setup program without saving any changes.  This means that any changes made while in the Setup program are discarded and NOT SAVED.  Pressing the <Esc> key in any of the four main screens will do this.

Load Setup Defaults

Resets all of the setup fields to their defaults.  You can also press the <F5> key anywhere in the Setup program to do this.

This selection loads the default Setup values from the ROM table.

Discard Changes

Discards any changes you made during the current Setup session without exiting the program.  You can also press the <F6> key anywhere in the Setup program to do this.

This selection loads the CMOS RAM values that were present when the computer was turned on.


Installing and Configuring Motherboard Options

This chapter describes the following:

•	Jumper block locations and functions

•	Procedures to remove and install optional components

•	Information about replacing the battery


Before You Begin

•	Be sure to do each procedure in the correct order.

•	Set up an equipment log to record the system model and serial numbers, all installed options, and other information about the system.  If you need this information, it will be easier to consult the log than to open up and examine the system.

•	You will need a medium flat-bladed screwdriver and a jumper removal tool, such as a pair of fine needle-nosed pliers.  We recommend that you use an antistatic wrist strap and a conductive foam pad when working on the board.

WARNING

The procedures in this chapter assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment.

WARNING

Disconnect the system from its power source and from any telecommunications links, networks or modems before doing any of the procedures described in this chapter.  Failure to disconnect power, telecommunications links, networks or modems before you open the system or do any procedures can result in personal injury or equipment damage.  Some circuitry on the motherboard may continue to operate even though the front panel power button is off.

CAUTIONS

Electrostatic discharge (ESD) can damage components.  Do the procedures described in this chapter only at an ESD workstation.  If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis.

Add-in boards can be extremely sensitive to ESD and always require careful handling.  After removing the board from its protective wrapper or from the system, place the board flat on a grounded, static-free surface, componentside up.  Use a conductive foam pad if available, but not the board wrapper.  Do not slide the board over any surface.


Jumper Block Overview

The motherboard contains configuration jumpers that make it possible to change the system configuration.  For instance, you can prevent access to the system Setup program by moving a jumper.  If you forget your system password, you can clear the password by moving a jumper.  The system has been properly configured at the factory.  Normally, the only time you will ever change a jumper is if you need to:

•	Change the system operating speed

•	Clear the User or Administrator password

•	Reset the CMOS RAM settings to the default values

•	Disable or enable access to the Setup program

•	Upgrade the BIOS

•	Recover from a corrupted BIOS during a BIOS upgrade

Figure 2 shows the location of the jumper blocks on the motherboard.  Descriptions of how to change the jumpers follow Figure 2.

CAUTION

Do not squeeze the pliers or other tool you use to remove a jumper, or you might bend or break the pins.

•	NOTES

A jumper is a small plastic-encased conductor that slips over jumper pins, as shown in Figure 2.  To change a jumper setting, use a pair of fine needle-nosed pliers to remove the jumper from its current location and slide it onto the new pins to obtain the desired setting.

The Recovery Boot enable jumper is briefly described in Appendix A.  The jumper is intended to be used only if the BIOS has been corrupted during a BIOS upgrade.

Figure 2.	Jumper Block Locations


Microprocessor/Bus Speed/Clock Ratio Jumpers

These jumpers set the microprocessor, PCI, and ISA bus frequencies and the clock ratio.  The jumpers should be changed only when you upgrade the microprocessor.

	200 MHz Microprocessor 66 MHz Host Bus Freq. 3x Clock Ratio 33 MHz PCI Bus Freq. 8.3 MHz ISA Bus Freq.
	180 MHz Microprocessor 60 MHz Host Bus Freq.  3x Clock Ratio 30 MHz PCI Bus Freq. 7.5 MHz ISA Bus Freq.
	166 MHz Microprocessor 66 MHz Host Bus Freq.  2.5x Clock Ratio 33 MHz PCI Bus Freq. 8.3 MHz ISA Bus Freq.
	150 MHz Microprocessor 60 MHz Host Bus Freq. 2.5x Clock Ratio 30 MHz PCI Bus Freq. 7.5 MHz ISA Bus Freq.


How to Clear the User Password

This procedure should only be done if you have forgotten the user password.

1.	Turn off power and remove the system cover.

2.	Move the jumper on J6D1 from pins 27-29 to pins 25-27.

3.	Turn on power and allow the system to boot.

4.	Turn off power.

5.	Move the jumper back to pins 27-29.

6.	Replace the system cover and turn the power back on.


How to Clear CMOS RAM

This procedure should be done after the system BIOS is updated (see Appendix A).

CAUTION

Do not use this procedure if your system is running Windows 95.  Clearing CMOS RAM after a BIOS upgrade erases the Plug and Play data in the CMOS RAM.  To clear CMOS RAM on a Windows 95 system, press the <F5> key from anywhere in the Setup program.  This resets all Setup options to their defaults.  See Chapter 2 for information on the Setup program.

1.	Turn off power and remove the system cover.

2.	Move the jumper on J6D1 from pins 20-22 to pins 18-20.

3.	Turn on power and allow the system to boot.

4.	Turn off power.

5.	Move the jumper back to pins 20-22.

6.	Replace the system cover and turn the power back on.


How to Disable Access to the Setup Program

To prevent access to the Setup program, do the following:

1.	Turn off power and remove the system cover.

2.	Move the jumper on J6D1 from pins 28-30 to pins 26-28.

3.	Replace the system cover and turn power back on.


How to Enable Access to the Setup Program

To enable access to the Setup program, do the following:

1.	Turn off power and remove the system cover.

2.	Move the jumper on J6D1 from pins 26-28 to pins 28-30.

3.	Replace the system cover and turn power back on.


Installing an OverDrive® Processor

This section tells how to install an OverDrive processor upgrade.  The OverDrive processor comes with a heat sink and fan mounted on top.


Installing the Upgrade

To install the upgrade, do the following:

1.	Observe the precautions in “Before You Begin.”  We recommend you take the following steps to reduce the risk of electronic discharge damage to the processor and mother board components:

—	Touch the metal chassis before touching the processor or motherboard.  Keep part of your body in contact with the metal chassis to dissipate the static charge while handling the processor.

—	Avoid moving around needlessly.

2.	Turn off all peripheral devices connected to the system, and turn off the system.

WARNING

The microprocessor and heat sink may be hot if the system has been running.  Also, there may be sharp pins and edges on some board and chassis parts.  Contact should be made with care.  Consider wearing protective gloves.

AVERTISSEMENT

Le microprocesseur et le dissipateur de chaleur peuvent être chauds si le système a été sous tension. Faites également attention aux broches aiguës des cartes et aux bords tranchants du capot. Nous vous recommandons l'usage de gants de protection.

WARNUNG

Der Mikroprozessor und der Kühler sind möglicherweise erhitzt, wenn das System in Betrieb ist. Außerdem können einige Platinen und Gehäuseteile scharfe Spitzen und Kanten aufweisen. Arbeiten an Platinen und Gehäuse sollten vorsichtig ausgeführt werden. Sie sollten Schutzhandschuhe tragen.

AVVERTENZA

Se il sistema è stato a lungo in funzione, il microprocessore e il dissipatore di calore potrebbero essere surriscaldati. Fare attenzione alla presenza di piedini appuntiti e parti taglienti sulle schede e sul telaio. È consigliabile l'uso di guanti di protezione.

ADVERTENCIAS

Si el sistema ha estado en funcionamiento, el microprocesador y el disipador de calor pueden estar aún calientes. También conviene tener en cuenta que en el chasis o en el tablero puede haber piezas cortantes o punzantes. Por ello, se recomienda precaución y el uso de guantes protectores.

3.	Figure 1 shows the location of the processor socket.  You must first remove the clamps over the heat sink and microprocessor.  Insert a small flat-bladed screwdriver into the slot on the end of the clamp.  Release the clamp by pushing outward on the blade of the screwdriver as shown in Figure 3.  As you move the clamp away from the socket, ease the clamp up and away from the processor and heat sink.  When you remove the clamp, the heat sink will slide off the processor.

CAUTION

When you remove the heat sink clamp, avoid scraping the clamp against any motherboard components.

Figure 3.	Removing the Spring Clamp, Microprocessor, and Heat Sink

4.	Push the lever on the processor socket down and out (away from the socket) until it pulls up freely.  Lift the lever until it stands straight up.  Remove the processor from the socket.  Do not touch or bend the pins.

5.	Place the processor in a piece of conductive foam and store it in an antistatic package.

6.	Remove the upgrade processor from its antistatic package; do not touch or bend the pins.

7.	Align the upgrade processor as shown in Figure 4 (A is pin 1).

8.	With the upgrade processor in place, lower it gently, being careful not to bend the pins.  Push the lever on the socket down until it snaps into place.

9.	If the upgrade processor has a fan power cord, attach the cord to the microprocessor fan connector (see Chapter 5).

Figure 4.	Installing a Processor Upgrade


Installing SIMMs

The motherboard contains four 72-pin, tin lead SIMM sockets. You can configure the system memory from 8 MB to 256 MB.  The sockets are arranged as banks 0 and 1 (Figure 5).  Two sockets make up one bank.

When adding memory, follow these guidelines:

•	When you install SIMMs, you must completely fill at least one bank; that is, you must install SIMMs in both sockets of the bank.

•	The computer automatically detects the installed memory, so it doesn’t matter which bank is used, as long as both sockets in the bank are filled.

•	Both SIMMs in one bank must be the same size.  For example, don’t install a 4 MB SIMM in one socket of bank 0 and an 8 MB SIMM in the second socket of bank 0.  You may, however, use different size SIMMs in different banks.

•	When adding SIMMs, use only tin lead,
72-pin, 60 ns fast page-mode or EDO DRAM.  Faster devices will not improve system performance.

Figure 5.	Location of SIMM Sockets

•	NOTES

The motherboard supports parity (x 36) or non-parity (x32) SIMMs.  Error checking and correction is supported with parity and ECC SIMMs.  There is no Error checking and correction with non-parity SIMMs.

All SIMMs must be tin lead, 72-pin, with 60 ns or faster EDO or fast page-mode DRAMs.

All SIMM socket sites in a bank must contain the same size SIMMs.

The motherboard only supports 64 MB SIMMs based on 64 Mbit technology.  64 MB SIMMs based on 16 Mbit technology are not supported.

Table 2.	Memory Options for SIMM Sockets

For a total  system  memory  of	Install a SIMM of the  following size in  both sockets of  bank 0	Install a SIMM of the  following size in  both sockets of  bank 1

128 MB	64 MB (128 MB total in socket bank 0)	Empty
256 MB	64 MB (128 MB total in socket bank 0)	64 MB (128 MB total in socket bank 0)

To install SIMMs, do the following procedure:

1.	Holding the SIMM only by the edges, remove it from its antistatic package.

2.	Position the SIMM at about a 45° angle relative to the motherboard.  Make sure the small notch in the middle of the bottom edge of the SIMM aligns with the notch in the SIMM socket.

3.	Insert the bottom edge of the SIMM into the SIMM socket and make sure it is seated firmly.

4.	When the SIMM seats correctly, hold it at each end and gently push the top edge towards the retaining clips of the connector until the SIMM snaps into place (Figure 6).  If the SIMM does not install correctly, gently spread the retaining clips just enough so that you can pull away the top edge of the SIMM and try again.

Figure 6.	Installing a SIMM


Removing SIMMs

To remove a SIMM, do the following:

1.	Observe the precautions in "Before You Begin."

2.	Turn off all peripheral devices connected to the system.

3.	Turn off the system.

4.	To gain access to the SIMM sockets, remove the system cover.

5.	Gently spread the retaining clip at each end of the SIMM, just enough to allow you to rotate the top edge of the SIMM downward to an angle of about 45°.

6.	Holding the SIMM only by the edges, lift it away from the socket, and store it in an antistatic package.

7.	Reinstall and reconnect any parts you removed or disconnected to gain access to the SIMM sockets.


Replacing the Battery

A lithium battery, installed in a socket on the motherboard, provides power for the real-time clock and CMOS RAM.  Figure 1 shows the location of the battery.

The battery has an estimated life expectancy of three years.  When the battery starts to weaken, it loses voltage.  When the voltage drops below a certain level, the system settings stored in CMOS RAM (for example, the date and time) may be wrong.  If the battery fails, replace it with an equivalent battery.

As long as local ordinance permits, you may dispose of individual batteries as normal trash.  Do not expose batteries to excessive heat or fire.  Keep all batteries away from children.

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’li 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!

BIOS Update

The BIOS resides on a flash component.  You can upgrade a flash BIOS through software, without taking the computer apart or replacing the flash component.  This appendix tells how to upgrade your BIOS from a diskette.  The appendix also tells how to recover from an interrupted upgrade.  Your service representative can provide you with the latest BIOS upgrade for your computer.


Using the Upgrade Utility

1.	Write down your current Setup selections (Chapter 2).

2.	Insert the upgrade diskette in your diskette drive.

3.	Reboot the system.

4.	When the flash upgrade menu appears, choose “Update Flash Memory Area from a file.”

5.	When the menu asks you to enter a path/filename, use the arrow keys to select the .bio file, and press <Enter>.

6.	The utility asks for a confirmation that you want to load the new flash into memory.  Select “Continue with Programming.”

7.	After the upgrade completes, remove the upgrade disk.

8.	Reboot the system and start the Setup program.  Press <F5> to reset the BIOS defaults.  Then, use the copy of the Setup selections you made at the beginning of this procedure to set the options.


BIOS Recovery

It is unlikely that anything will interrupt the flash upgrade process.  However, if an interruption occurs, it is possible the BIOS could be left in an unusable state.  The steps below tell how to recover from this kind of problem.

NOTE

Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure.  You must monitor the flash recovery by listening to the speaker.

1.	Turn off power and remove the system cover.

2.	Move the Recovery Boot Enable jumper from pins 4-6 to pins 2-4.

3.	Insert the bootable flash upgrade diskette into diskette drive A.

4.	Turn on the computer.

5.	Listen to the speaker.  You should hear beeps in the following sequence:

a.	After you turn on the computer, the speaker beeps once.  This beep marks the beginning of the power on self test.

b.	After a short delay (less than 10 seconds), the speaker beeps again at a higher frequency.  This marks the beginning of the recovery process.  At this point, the recovery code is being copied into the flash device.

c.	After about 30 seconds, the speaker beeps twice at the higher frequency, marking the end of the recovery process.

6.	Turn the system off.

7.	Move the Recovery Boot Enable jumper back to pins 4-6.

8.	Replace the system cover, leave the flash upgrade diskette in drive A, and turn the system on.

9.	Continue with the original upgrade.

Installation Instructions

CAUTION

Follow these guidelines to meet safety and regulatory requirements when installing this board assembly.

Read and adhere to all of these instructions and the instructions supplied with the host computer and associated modules.  If the instructions for the host computer are inconsistent with these instructions or the instructions for associated modules, contact the supplier’s technical support to find out how you can ensure that your computer meets safety and regulatory requirements.  If you do not follow these instructions and the instructions provided by host computer and module suppliers, you increase safety risk and the possibility of non-compliance with regional laws and regulations.


Ensure Electromagnetic Compatibility (EMC)

Before computer integration, make sure that the host chassis, power supply, and other modules have passed EMC testing using a motherboard with a microprocessor from the same family (or higher) 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:

•	Certifications (see page 82)

•	External I/O cable shielding and filtering

•	Mounting, grounding, and bonding requirements

•	Keying connectors when mismating of connectors could be hazardous

If the host chassis, 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.


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
