W6-LI System Board Manual 5
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 trans-
fer rate), PCI and ISA slots, up to 512K of Level 2 cach
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
pleased with your purchase.

Chapter Quick Installation
We know that many experienced people prefer to read as
little of the documentation as possible. If this sounds like
you, here’s the short form to get up and running quickly.
Installing the W6-LI
1. Make backup copies of your installation and configu-
ration diskettes.
2. Ground yourself to prevent damaging static dis-
charge, then remove the W6-LI from its packaging.
3. Configure and verify the system board’s jumper set-
tings (refer to Jumper Settings in Chapter 2).
4. Install the CPU and the system memory (refer to
Chapter 3).
5. Install the system board into the chassis and make all
necessary case connections.
6. Install any ISA and PCI add-on peripherals (refer to
Chapter 3).
7. Now you can connect any optional devices (refer to
Chapter 3).
8. Turn the computer on and press the <F2> key
when you see the screen in Figure 1.1.

9. Set the time and date. Adjust the BIOS settings to
match yourconfiguration. If installing an IDE drive,
select the IDE device you wishto configure. Press
ENTER with Autotype Fixed Disk selected and the
BIOS will automatically configure the drive for you
(refer to Chapter 4).
10. After you have configured the Main Setup menu,
make any desired setting configurations in the Ad-
vanced and Security menu. Whenfinished, go to the
exit screen, select “Save Changes and Exit” and you
are finished with the BIOS configuration (see Chap-
ter 4).
11. Install your IDE CD-ROM drive and its device
drivers (optional). Refer to Chapter 3.
12. Install the sound controller device drivers (optional).
Refer to Chapter 5.
13. Install the SCSI device drivers (optional). Refer to
Chapter 5.

Configuring the W6-LI
Although the W6-LI system board is packaged in protec-
tive materials, it is important to use care while unpack-
ing 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 you
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.
Office Environment
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.

board.
Table 2-1: Jumper settings to select the CPU frequency. These setting
apply to both CPUs.NOTE: Before making your selection, verify that
jumper W12 is closed.
Table 2-2: Jumper settings for the CPU Voltage Identification (VID).
The power regulators on the system board (one for each CPU) are
capable of generating different voltages. VID is a hardware mechanism
used by each CPU to tell its power regulator what voltage to set.
NOTE: If the CPU supports VID, all jumpers on W1 and/or W2 must
removed ordamage may occur. W1 is for the Primary CPU and W2 is for
the secondary CPU.

Chapter 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 prob-
lems 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 Cor-
rection (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 conven-
tional 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 in-
stall 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 provid-
ing 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).
