Introduction

Introduction

Thank you for choosing the W6-LI system board. The
W6-LI is the highest performing advanced dual processor
solution for the industry's most demanding workstation
and server applications.

Based on the Intel 440FX PCIset, the W6-LI supports the
most advanced processor architecture, the Pentium Pro
which provides the speed and performance necessary to
address the most intensive computational applications.
Integrated Ultra Wide SCSI (up to 40MBytes/sec trans­fer rate), PCI and ISA slots, up to 512K of Level 2 cache
on each CPU and support of Universal Serial Bus (USB),
make this board powerful and feature rich.

The USB interface has a maximum bandwidth of 12Mbps
and can connect as many as 127 devices to a host system.
USB supports both standard devices that operate at the
full 12Mbps rate and low-end devices that use only a

1.5Mbps subchannel.

,

Designed to fit into the most modern ATX form factor,
the flexible W6-LI also features support for Fast Page
Mode (FPM) and Extended Data Out (EDO) DRAM
advanced memory, and Error Checking and Correction
(ECC). The ATX form factor allows critical components
such as floppy drive connectors, chassis fan, CPU and
memory to be strategically located so that full length
cards can be used in all slots.

Micronics builds all products to exacting standards, using
the highest quality components available. We are proud
to provide this system board and believe you will be

Configuring the W6-LI

Although the W6-LI system board is packaged in protec­tive materials, it is important to use care while unpack­ing and setting up.

Static Electricity

The W6-LI is shipped from the factory in an antistatic
bag. To reduce the possibility of damage, it is important
to neutralize any accumulated static charges on your
body before handling the board. The best way to do this
is to ground yourself using a special wrist or ankle strap.
If you do not have a strap, you should touch both of your
hands to a safely grounded object. After you have
grounded yourself, ground the W6-LI via the solder pads
surrounding one of its mounting holes.

Once the W6-LI is removed from its packaging, place it
on top of the antistatic bag. Carefully inspect the board
for damage which may have occurred during shipment.

Environment Considerations

Make sure the finished computer system is in an area with
good ventilation. The system should not be in direct
sunlight, near heaters, or exposed to moisture, dust or
dirt.

Installing the W6-LI

Introduction

This chapter explains how to install the W6-LI system
board, memory, CPU and peripherals.

WARNING: Before installing or removing any peripherals
or components, make sure you have a clear work space and
that you adhere to all anti-static precautions described in
Chapter 1. Micronics recommends only trained technicians
install and configure the system board.

Damage which occurs to the board while adding or removing
peripherals or components may void the warranty. If prob­lems arise while installing peripherals, contact the computer
dealer where you purchased the peripheral or Micronics’
Technical Support Department.

System Memory Support

The flexibility of the W6-LI is augmented by its support
for Error Checking and Correction (ECC), Extended
Data Out (EDO) and Fast Page Mode (FPM) DRAM
memory. The W6-LI supports Error Checking and Cor­rection (with 72-bit DIMMs only) via the chipset.

EDO memory is designed to keep data available to the
processor for an extended period of time. The EDO
memory support extends the performance of conven­tional DRAM memory. The result is an improvement in
memory-access performance on the W6-LI system board.

W6-LI System Board Manual

Chapter 3: Installing the W6-LI

Installing the W6-LI

Installation of the W6-LI system board depends on the type
of case you use. The W6-LI is designed for the standard
ATX form factor and must be installed in an ATX chassis.

NOTE: If you are unfamiliar with installing a system board,
Micronics highly recommends that you read the computer
user’s manual or contact your dealer’s technical support
department.

Tools Required

Micronics recommends using the following tools to in­stall the W6-LI:

❏ Small Phillips screwdriver
❏ Tweezers or a pair of needle-nose pliers
❏ Tray (to hold loose screws)

Equipment Required

Micronics recommends using the following equipment with
the W6-LI for a typical configuration:

❏ ATX chassis with standard hardware.
❏ A high-quality ATX power supply capable of providing

continuous power within a 3 volt range. A power filter
may be used with a noisy AC power source.

❏ PS/2 mouse and compatible keyboard.
❏ Eight ohm speaker.
❏ Standard ribbon cables for internal connections.
❏ Standard power cord (grounded).
❏ Heat sink with cooling fan for each CPU (required).

W6-LI System Board Manual

Chapter 3: Installing the W6-LI

System Memory

System memory is necessary to operate the W6-LI system
board. The W6-LI uses DIMMs, which provide a wider
data path than SIMMs, to carry more data.

The W6-LI has four 168-pin DIMM sockets for a maximum
of 512 Megabytes of RAM. Support is provided for EDO
DRAM memory and FPM DRAM memory. This chapter
will explain the type of DIMMs supported, list the rules for
adding memory to the W6-LI, give some examples of com­mon memory configurations and show how to physically
install the new DIMMs.

DIMMs Supported

For long
term
reliability,
Micronics
recom­mends using
DIMMs with
gold-plated
contacts.
The use of
tin-plated
contacts
may conflict
with the gold
alloy on the
DIMM
socket.

The W6-LI supports the following types of 60 or 70ns
DIMMs:

8MB (1Mx64/72)
16MB (2Mx64/72)
32MB (4Mx64/72)
64MB (8Mx64/72)*
128MB (16Mx64/72)*

*Subject to availability

Adding Memory

The following is a list of rules to follow when upgrading
DIMMs. If you follow these rules, your upgrade should be
trouble-free:

❏ Use 70ns or faster DIMMs.
❏ There are three (3) types of DIMM wiring configura-

tions: Non-parity - 64 bits wide, Parity and Error
Checking and Correction - 72-bits wide.

❏ All three types of DIMM configurations may be used

on the W6-LI, but not simultaneously.

W6-LI System Board Manual

19

Chapter 3: Installing the W6-LI

❏ Upgrade DIMMs one bank at a time. Start with Bank

0, then work your way up (one DIMM per bank),
adding memory from the smallest to the largest size.

❏ Install the two types of memory in separate banks. The

memory will default to the speed of the slowest RAM
installed.

Installing Device Drivers

This chapter explains how to install the software device
drivers and utilities necessary to utilize the optional
sound and SCSI support. Other drivers and utilities are
available through our online services.

About Device Drivers

Device drivers are necessary for the computer system to
communicate with devices such as CD-ROM drives,
sound controllers, graphics adapters or devices that are
not natively supported by the system BIOS. Once started,
device drivers remain active in the background of the
computer system. Usually a device driver is added to the
CONFIG.SYS file, the AUTOEXEC.BAT file or both.

Installing the Sound Drivers

Once you have connected your external sound devices, you
can install the sound drivers. NOTE: If you are installing a
CD-ROM drive, it is recommended you install it before
setting up the sound devices. See Installing a CD-ROM
Drive in Chapter 3.

1. Follow the instructions in Chapter 3 on connecting ex­ternal sound devices.

2. If you previously installed another sound card, remove
it and all associated files from your AUTOEXEC.BAT
and CONFIG.SYS files. If you are using Windows 3.1x,
you must also remove all associated files from the
WIN.INI and SYSTEM.INI files. (For more infor­mation, please contact the sound driver manufacturer.)

3. Start your computer system.

Appendix C: Beep and POST Codes

Appendix

Beep and POST Codes

Beep codes are a series of beeps sent through the
speaker which indicate a problem during the Power On
Self Test (POST). If text appears on the video screen,
the W6-LI has completed POST; any other tone from
the speaker indicates something other than a POST
error. These tones are not described in the tables on the
following pages.

The beep error codes are a series of beeps. The duration
of the beep tones are constant, but the length of the
pauses between the beeps varies. For example: a 1-3­3 beep code will sound like one beep, a pause; three
beeps consecutively, another pause and then three
more beeps.

One beep code is often misunderstood. If a video card
is not installed or is failing, the system board will
generate a long-short-long-short beep code. This is
often interpreted as a 1-2-1 beep code. But POST
errors always vary in the length of the pause and not the
duration of the beep tone.

Another way of identifying a POST error is to use a
device called a POST card. This peripheral card is
inserted into one of the ISA slots and has an LED (or
LCD) read out showing the contents of port 80h.

The following tables list all beep codes and POST
routines.

Appendix E: Updating the System BIOS

Appendix

E

If you
encounter
any
problems
during this
process, or
if you have
questions
about the
procedure,
please call
Technical
Support.

Updating the System BIOS

The Micronics system boards are designed so that the
BIOS can be reprogrammed using a BIOS file. You can
easily FLASH a BIOS by following the steps below:

1) After downloading the appropriate BIOS file from our
BBS or Website, extract it to a bootable MS-DOS 6.X
diskette.

2) Reboot your system with the MS-DOS 6.X diskette
in the A: drive. To make sure a clean DOS environ­ment is loaded, press the F5 key while “Starting MS­DOS” is displayed. After the system has rebooted,
the cursor will appear at the A:> prompt.

3) Now you can run the FLASH utility. The filename
should be “PHLASH.EXE.” Type this filename at
the A:> prompt (but don’t include its extension),
followed by a space and the BIOS ROM image’s
filename. This file will be included in the download
and has a file length of about 131K or 262K. For
example, to update the W6-LI to BIOS version 01,
you would type:

PHLASH W6LI_01.ROM [ENTER]

4) After the update process has completed and the
system reboots, verify that the new BIOS version
appears on-screen. If you have problems during this
process, or if you have questions about the proce­dure, please call Technical Support.

NOTE: If the BIOS is somehow erased or does not seem to
accept the upgrade, you can purchase a new BIOS from
MicroNiche Information Systems (800-733-9188). There
is a $30.00 fee plus shipping charges for this service. (Price
and availability subject to change.)

If you prefer to send your system board in for the upgrade,
the RMA department offers this service free of charge if
your system board is under warranty.

in which the data is sent one bit at a
time over a single wire. See Parallel.

Serial Port - A communications port
used to connect peripherals such as
modems and mice.

Setup - A program that allows you to
make changes to the system configu­ration.

Shadow RAM - A technique used to
load a duplicate copy of BIOS from
slower ROM into faster RAM. This
enhances system performance be­cause it provides higher access speed
to the BIOS.

Small Computer System Interface ­See SCSI.

SRAM - An acronym for Static Ran­dom Access Memory. A type of
memory that can retain data without
requiring a regular clock signal.

Glossary

Although they are faster than DRAM,
they hold less data and are more ex­pensive.

Synchronous - Protocols that require
the clocks of communicating ma­chines or devices to be coordinated.

Synchronous Cache - A type of cache
that uses a clock signal to latch the
inputs and the data output. This struc­ture spreads the cache access across
two or three cycles while maintaining
a bandwidth of one access per cycle.
Improves performance by 5-10%.

Terabyte ­storage capacity. One Terabyte is equiva­lent one-thousand gigabytes, one-million
megabytes, or 1,099,511,627,766 bytes.

VESA - An acronym for Video Elec­tronics and Standards Association.

VESA Local Bus (VL-Bus) - A high
performance bus designed by VESA.
A 32-bit version of the ISA bus which
operates at the speed of the
computer’s CPU. See PCI, EISA and

ISA.

A measurement for very large

Wide SCSI - A SCSI-2 enhancement
that allows data to be transferred 16
or 32 bits at a time on the SCSI bus
instead of 8 bits at a time.

Write-Back Cache - Upon a cache
hit, the cache is updated and the main
memory is not affected. Upon a cache
miss, only the main memory is up­dated.

Write-Through Cache - Upon a
cache hit, the cache and the main
memory are updated. Upon a cache
miss, only the main memory is up­dated.

VID - Voltage Identification. A hard­ware mechanism used by the CPU to
tell its power regulator what voltage
to set.

VRM - Voltage Regulator Module.
Supplies CPU specific voltages for the
Secondary CPU.

Warm Boot - Restarting the system
by simultaneously pressing the
<Ctrl>, <Alt> and <Delete> keys.
