capabilities, includes the following features:

• Ready for next generation OverDrive processor

• Backward compatibility with Intel microprocessor architecture

• Onchip numeric coprocessor (compatible with the Intel486 DX

processor and compliant with ANSI/IEEE standard 754-1985)

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

• Burst-mode bus cycles

Chapter 5 tells how to upgrade the CPU.

System Memory

The system supports base (conventional) and extended memory. Operating
systems such as MS-DOS†, OS/2†, UNIX†, and all application programs use
base memory. For better performance, Windows 95, OS/2 and UNIX as well
as many MS-DOS applications use extended memory. For the system
memory map, see Chapter 7.

The system supports up to 128 MB of DRAM. DRAM is implemented
through four 72-pin single in-line memory modules (SIMMs). Chapter 5 tells
how to install memory modules.

Cache Memory

The Pentium microprocessor includes 16 KB of cache on the chip. The core
chip set includes a cache controller that supports secondary write-back cache
memory. The system can support 256 KB of secondary cache memory.

System Product Guide 1-3

Enhanced PCI/IDE Peripheral Interface

The system provides two high speed, 32-bit PCI/IDE interfaces. Each
PCI/IDE interface supports:

• Up to two IDE hard drives on the PCI bus

• PIO Mode 3 and 4 and AT API devices

• In conjunction with the system BIOS provides an option that supports

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

If you are using third-party controllers or non-IDE hard disk drives, the
system Setup program provides options that allow you to manually
configure the controller functions.

System I/O

A single onboard I/O controller integrates the functions for the serial ports,
parallel port, and diskette drive. This component provides

• Multimode bi-directional parallel port

− Standard mode: Centronics-compatible operation

− Support for Enhanced Parallel Port

− High-speed mode: support for Enhanced Capabilities Port

• Two RS-232C-compatible 9-pin serial ports.

• Industry standard diskette drive controller

• Real-time clock for the system

• Keyboard and mouse controller

1-4 Product Description

System BIOS

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

The system 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.

BIOS Upgrades

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

The DOS-based upgrade utility (Flash Memory Update Program, FMUP) has
three main options:

• Update the flash BIOS from a file on disk.

• Copy the current BIOS code from the flash device to a disk file to

provide a backup if the upgrade cannot be finished.

• Compare the flash BIOS to a disk file to verify that the versions are the

same and make sure that the system has the correct BIOS version.

Appendix A tells how to run the BIOS upgrade utility. For information
about the latest BIOS update, contact your service representative.

Plug and Play

Your system is fully Plug and Play compatible. Plug and Play makes it
easier to add components to your system. This feature provides these
important benefits:

• PCI cards and Plug and Play ISA cards are configured automatically

• IDE hard disks and main memory are configured automatically

• Windows 95 Plug and Play ready

System Product Guide 1-5

Expansion Slots

The system has two dedicated 16-bit ISA/AT-compatible, three dedicated
PCI-compatible expansion slots, and one combination slot that can be used
by either a PCI or an ISA board. See Chapter 4 for more information about
expansion slots and installing add-in boards.

Power Management

Your system supports the Intel/Microsoft Advanced Power Management
(APM) specification. Advanced Power Management consists of one or more
layers of software that support power management in computer with power
manageable hardware. Power Management works with APM-capable
operating systems to reduce power consumption in your system. IDE hard
drives and monitor/graphics card combinations that support the VESA
DPMS standards can be put to sleep along with the processor after a user­defined period of inactivity. The system Setup program provides options for
defining a time and a hotkey to enable the power saving mode.

Integrated 16-bit Audio

There is an optional integrated audio solution from Crystal that provides
built in support for the following standards:

• Sound Blaster† Pro

• Multimedia PC Level 2

• MPU-401

The system includes software for getting the most out of your audio system.
Appendix C tells more about the audio system and software.

1-6 Product Description

Video Graphics Subsystem

The graphics subsystem features the S3 Trio64V+ integrated PCI graphics
controller. The Trio64V+ controller is a high performance graphics engine
that provides the following features:

• Standard 1 MB of graphics memory, expandable to 2 MB

• Multiple screen resolutions/color densities available

• Support for 8-bit bi-directional VESA advanced feature connector

• Support for VESA Display Power Management Signaling (DPMS)

monitor power savings modes

• Support for VESA Display Data Channel (DDC2B) that permits transfer

of monitor identification and resolution support data for ease of use

A VESA-compliant 8514/A feature connector is provided on the system
board in addition to a standard 15-pin analog VGA connector on the back
panel. The VESA pass-through connector is useful when an auxiliary video
subsystem is installed in one of the expansion slots such as an 8514/A
compatible video card or DVI board.

Appendix D tells more about the Trio64V+ graphics controller.

Power Supply

The system has a 200 watt power supply to provide power for onboard
resources, add-in boards, and drives. A switch on the system back panel sets
the power supply to operate at either

• 115 V ac (in the range of 90-135 V ac; 4 A)

• 230 V ac (in the range of 180-265 V ac; 2 A)

For power supply output ratings, see Chapter 7.

System Security

System security is provided by password options enabled through the Setup
program (see Chapter 3).

System Product Guide 1-7

Battery

A battery on the system board provides power backup for the real-time clock
and CMOS RAM. Chapter 5 provides information about replacing the
battery.

You can set the time for the clock and the CMOS values by using the system
BIOS Setup program, described in Chapter 3.

Speaker

A speaker is mounted on the system board. The speaker provides audible
error code information (beep codes) during the power-on self test (POST) if
the system cannot use the video interface. See Chapter 6 for beep code
information.

2-6 Installing Your System

Turning on the System at First Start-up

To power up the system for the first time, follow these steps:

1. All system components such as a video monitor and keyboard should be
connected before turning on the system. All connections should be
made while the system is off.

2. Connect the female end of the AC power cord into the AC power input
socket at the rear of the system, and plug the male end of the power cord
into a grounded electrical outlet.

3. Turn on power to the monitor.

4. Press the power button at the front of the system (the green power LED
on the front panel will go on). The system will power up and
immediately begin the power-on self test (POST).

When you boot the system, the POST checks the settings stored in CMOS
RAM against the actual hardware configuration. During the memory test,
the POST displays the amount of memory that it has tested. The POST takes
approximately 15 seconds to complete. If you want to go into the Setup
program, press the <F1> key after the POST starts the memory test, but
before the system boots up (see Setup, Chapter 3). Your next step after
booting depends on what POST finds. See the following possibilities:

System Product Guide 2-7

What happens What to do

If the settings in CMOS RAM
configuration, and if the POST does not find any
errors, the power-on testing continues.

If the POST finds a fatal error (an error that prevents
the system from continuing the boot process), it
generates a series of beeps. A specific number of
beeps indicates a certain error message.

If the POST finds a non-fatal error (an error that
doesn't stop the boot process from continuing), the
system displays a message in the following format:

Error message line 1
Error message line 2

Resetting the System

To reset the system, press the key sequence:

<Ctrl + Alt + Del>

You can also reset the system by shutting system power off and then
powering back up. To do this:

1. Press the front panel power control button.

2. Wait at least 20 seconds.

3. Press the power button. The system will power up and immediately
begin the power-on self test (POST).

Resetting the system will:

• Clear the system memory

• Restart the power-on self test (POST)

• Reinitialize all peripherals

• Load the operating system

Using Keyboard Shortcuts

The keyboard controller supports using shortcuts to reset the system (soft
boot) and toggle between fast (turbo) and slow CPU speed.

Normally the CPU runs in fast (turbo) mode at its full rated speed. Some
application software requires running the system in slow mode. Changing
to fast mode by using shortcuts may not be supported by some systems or by
some applications, in which case you can specify fast or slow mode by using
the Setup program. For instance the set slow or fast mode keyboard shortcut
will not work if the CPU is being operated in protected mode. (When you
operate Windows in enhanced mode, the CPU is operating in protected
mode.)

The numbers and symbols in the following tables refer to the keys on the
numeric keypad.

2-10 Installing Your System

Using the Setup Program

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

If the system does not operate as described here, see the chapter titled
“Solving Problems” for problem descriptions and error messages.

If you want to go into the Setup program, press the <F1> key after the POST
starts the memory test, but before the system boots up. You have about five
seconds to press <F1> to enter Setup before the boot process continues.

Make a Record of the Setup Configuration

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

This section describes the options found on the Plug and Play configuration
subscreen.

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 and Use ICU (ISA
Configuration Utility). The default is Use Setup Utility.

If Use ICU is selected, the BIOS will depend on run-time software to ensure
that there are no conflicts between ISA boards with Plug and Play
capabilities and those without. Choosing Use ICU enables Boot with PnP OS
and disables all other options.

Boot with PnP OS

Enables the PC to boot with an operating system capable of managing Plug
and Play add-in cards. The options are None, Other, and Windows 95. The
default is Windows 95. If Configuration Mode (above) is set to Use Setup
Utility, this option will not be visible.

ISA Shared Memory Size

Enables you to “unshadow” a block of the upper memory area. The options
are Disabled, 16 KB, 32 KB, 48 KB, 64 KB, 80 KB, and 96 KB. The default is
Disabled. If this is set to Disabled, the ISA Shared Memory Base Address
(described below) will not be visible.

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.

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.

System Product Guide 3-17

IRQ 3, 4, 5, 7, 9, 10, 11, 12

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.

3-18 Using the Setup Program

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.

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.

Taking Your System Apart

This chapter tells how to take apart and reassemble the major parts of the
system. Chapter 5 describes how to remove and install system board
components.

Before You Begin

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

• The procedures (and warnings) for removing and reinstalling the side

covers are assumed to precede all other procedures described in this
chapter.

• 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 Phillips screwdriver (#2 bit). We recommend that you

use an antistatic wrist strap and a conductive foam pad when working
on the system.

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 internal modems before you open the system
or do any procedures can result in personal injury or
equipment damage.

Do not operate the system with the cover removed.
Always replace the cover before turning on the system.

The total power draw on the system must not exceed the
specifications for the power supply. See Chapter 7 for the
power supply specifications.

Electrostatic discharge (ESD) can damage disk drives, add-in
boards, and other components. Conduct 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, component-side up. Use
a conductive foam pad if available, but not the board
wrapper. Do not slide the board over any surface.

Add-in Board Considerations

The next few procedures tell how to remove and install slot covers and add­in boards. As an aid to installing boards in your system, this section
describes the arrangement and numbering conventions for the slot
connectors on the system board.

ISA-compatible add-in boards can be installed in any of the system board
ISA slots. PCI-compatible add-in boards can be installed in any of the PCI
slots.

CAUTIONS

!

▲

▲

Do not overload the system board by installing add-in
boards that draw excessive current. The system is designed
to provide 2 A (average) of +5 V power for each board in the
system. The total +5 V current draw in a fully-loaded
system (all add-in board slots filled) must not exceed 14 A.

Add-in boards can be extremely sensitive to ESD and always
require careful handling. Hold the board by the edges only;
do not touch the electronic components or gold connectors.
After removing a board from its protective wrapper or from
the system, place it flat on a grounded, static-free surface,
component-side up. Do not slide the board over any
surface.

Jumper Block Overview

The system board in your computer contains six jumper blocks with
moveable jumpers. The jumpers make it possible to change certain aspects
of the system configuration. For instance, you can prevent access to the
system Setup program by moving one of the jumpers. If you forget your
system password, you can clear the password by moving one of the jumpers.
The system has been properly configured at the factory. Normally, the only
time you will ever change the jumper is if you want to:

• Disable or enable access to the Setup program

• Reset the CMOS RAM settings to the default values

• Clear the system password

• Change the ISA bus speed

• Recover from a corrupted BIOS during a BIOS upgrade

Table 5-1 describes the function of the jumper blocks. Figure 5-2 shows the
location of the jumper blocks on the system board. Descriptions of how to
change the jumpers follow Figure 5-2.

CAUTIONS

!

▲

▲

If you change a jumper, you will need to remove the system cover
and possibly add-in boards or other system components. Be sure to
follow the precautions and procedures provided in Chapter 4 when
you remove the cover or other system parts.

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

Notes

A jumper is a small plastic-encased conductor that slips over jumper
pins. 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.

How to Set the ISA Bus Clock Speed Jumper

Depending on the speed of the CPU in your system, the default setting for the
ISA bus clock jumper ranges from 7.5 MHz to 8.33 MHz. You may be able to
improve the performance of some ISA add-in boards by speeding up the ISA
bus clock speed. However, keep in mind that some ISA add-in boards may
have problems operating above the ISA bus clock standard of 8 MHz. If you
change the jumper on J10C4 to pins 1-2 and experience operating problems
with ISA boards, you may want to move the jumper back to the slower
position. Table 5-2 below shows how the two settings for jumper J10C4
affect the ISA bus clock speed for different CPUs.

5-12 Installing and Configuring System Board Options

Installing Single In-line Memory Modules (SIMMs)

The system board contains four 72-pin, tin lead SIMM sockets. The sockets
are defined as Bank 0 and Bank 1. Two SIMM sockets make up one SIMM
bank. The types of SIMMs that can be installed in the system are as follows:
4 MB, 8 MB, 16 MB, and 32 MB. The computer can support up to 128 MB of
DRAM.

When you install SIMMs, you must completely fill at least one 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. You can
mix SIMM sizes and types between banks, but not within a bank. For
example, you should not install a 4 MB SIMM in one socket of Bank 0 and
install an 8 MB SIMM in the second socket of the same bank. Likewise, you
should not mix EDO and Fast Page Mode (FPM) SIMMs in the same bank.
You can, however, install 4 MB SIMMs in Bank 0 and 8 MB SIMMs in Bank 1.
You can also install EDO SIMMs in one bank and FPM SIMMs in the second
bank. When adding SIMMs, use only tin lead, 72-pin, EDO or FPM DRAM.
Table 5-4 shows which speed DRAMs should be used with which CPU.
Faster devices can be used but will not improve system performance.

Table 5-4. Required SIMM Speeds

CPU Bus
Speed

50 MHz 70 ns 70 ns
60 MHz 70 ns 70 ns
66 MHz 60 ns 70 ns

Use EDO DRAM of at
Least This Speed

Use Fast Page Mode DRAM
of at Least This Speed

By using various combinations of SIMMs, you can configure the system
memory from 8 MB to 128 MB. Table 5-5 shows the possible combinations of
SIMM types and the resulting amount of system memory. Remember that
each SIMM bank contains two SIMM sockets. Therefore, the amount of
memory in one bank includes the memory installed in both sockets in that
bank.

5-14 Installing and Configuring System Board Options

To install SIMMs, do the following procedure:

1. Observe the precautions in “Before You Begin.”

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

3. Turn off the system.

4. Remove any full-length add-in boards or other components as needed to
gain access to the sockets (see Chapter for assembly procedures and
precautions).

5. Holding the SIMM only by the edges, remove it from its antistatic
package. A SIMM has a small notch in the middle of the bottom edge
that mates with a raised bump in the SIMM socket. There is also a notch
at one side of the module.

6. Firmly insert the bottom edge of the SIMM into the socket (Figure 5-5).
Press evenly against the module’s upper corners to rotate it to a vertical
position secured by the retaining clips of the connector. When properly
installed, the SIMM is oriented at a 90° angle relative to the system
board. 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.

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

Installing Video DRAM

! WARNINGS

▲

The optional video graphics controller comes with 1 MB of video DRAM
installed on the system board. You can also install an additional 1 MB of
video DRAM. The additional memory plugs into the empty sockets shown
in Figure 5-6. Each socket holds a 256 KB x 16, 60 ns (or faster), SOJ DRAM
component. Both sockets must be empty or both must be populated. You do
not have to set any system jumpers if you install the additional video
memory.

Contact your service representative for a recommendation on specific part
numbers for installing the additional video DRAM.

Before you can install or remove video DRAM, you must remove the system
cover and any add-in boards that are blocking access to the video memory
sockets. After you are finished, replace any system parts you removed.

Replacing the Battery

A lithium battery on the system board provides power to the real-time clock
and CMOS RAM when the system is powered down. The battery has an
estimated life expectancy of three years. When the battery starts to weaken,
it looses voltage; when the voltage drops below a certain level, the system
setting stored in CMOS RAM (for example, the date and time) may be
wrong. If the battery fails, you will need to replace it with an equivalent
battery. Figure 5-1 shows the location of the 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.

Problems at Initial System Start-up

Problems that occur at initial start-up are usually caused by incorrect
installation or configuration. Hardware failure is a less frequent cause.

___ Are all cables correctly connected and secured?
___ Are the configuration settings correct in Setup? See Chapter 3.
___ Are all drivers properly installed?
___ Are jumpers on the system board correct if changed from the default

settings? See Chapter 5 for defaults.
___ Are all jumper and switch settings on add-in boards and peripheral

devices set correctly? For the valid settings, see the documentation

shipped with these devices. Ensure that there are no conflicts, for

example, two add-in boards sharing the same interrupt.
___ Is the power supply set to the proper input voltage? See Chapter 2.
___ Are add-in boards and disk drives installed correctly?

See Chapter 4.
___ Is there a keyboard attached?
___ Is a bootable diskette installed in drive A?
___ If the system has a hard disk, is it properly formatted or defined?
___ Are all SIMMs installed correctly? Try reseating the SIMMs. See

Chapter 5.
___ Is the operating system properly loaded? See the operating system

documentation.

6-4 Solving Problems

Problems After the System Has Been Running
Correctly

After the system hardware and software have been running correctly,
problems often indicate equipment failure. Go through the checklist below
to see if the situation is one that may be easily corrected.

If the problem recurs after you have checked and corrected all of these items,
refer to the troubleshooting procedures (see "Troubleshooting Procedure" in
this chapter).

___ If you are running the software from a diskette, try using a new copy.
___ If you are running the software from a hard disk, try running it from a

diskette. If the software runs correctly, there may be a problem with the
copy on the hard disk. Reinstall the software on the hard disk and try
again. Make sure all the necessary files are installed.

___ Try clearing CMOS RAM (Chapter 5) and running Setup (Chapter 3).
___ If the problems are intermittent, there may be a loose cable, dirt in the

keyboard (if keyboard input is incorrect), a marginal power supply, or
other random component failures.

___ A transient voltage spike, power outage, or brownout may have

occurred. Symptoms of voltage spikes include a flickering video
display, unexpected system reboots, and the system not responding to
user commands. Reload the software and try again.

___ Voltage spikes can occasionally cause the heads of the disk drive to

contact the disk. This can corrupt or destroy data files. If you are
experiencing voltage spikes on the power line, install a surge suppresser
between the power outlet and the system power cord.

___ Try reseating the SIMMs.
