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  
mostadvancedprocessorarchitecture,thePentiumPro ,  
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 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  
pleased with your purchase.

Chapter  
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.  
2
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.  
EnvironmentConsiderations  
Makesurethefinishedcomputersystemisinanareawith  
good ventilation. The system should not be in direct  
sunlight, near heaters, or exposed to moisture, dust or  
dirt.

Installing the W6-LI  
Introduction  
3
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-accessperformanceontheW6-LIsystemboard.

Chapter 3: Installing the W6-LI  
SystemMemory  
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.  
TheW6-LIhasfour168-pinDIMMsocketsforamaximum  
of 512 Megabytes of RAM. Support is provided for EDO  
DRAM memory and FPM DRAM memory. This chapter

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  
ontheW6-LI, butnotsimultaneously.

sor.  
When installing a second processor, a VRM module  
must be installed into header J1. In addition, the  
second processor must have the same speed rating  
and cache amount as the main processor.  
WARNING: Pentium Pro processors require a heat-sink  
with a cooling fan. Failure to provide adequate cooling of the  
processor may seriously affect system performance or cause  
permanent damage to the processor.  
NOTE: If your operating system supports dual processors,  
you may need to reconfigure or reinstall your operating

ROM’s documentation, making sure the red stripe  
on the cable is aligned with pin 1 of the connectors.  
2. Connect the audio cable to the CD-ROM drive's  
audio connector.  
3. Connect the other end of the audio cable to the  
MPC-2 compatible CD-ROM audio connector on  
the W6-LI system board (see Figures 2.1 and 2.2).  
4. Connect the power supply cable to the CD-ROM  
drive's power connector.  
5. InstalltheCD-ROMdevicedrivers. CD-ROMdrives  
require device drivers to access the drive and are  
generally provided by the manufacturer of the CD-  
ROM drive. Usually one device driver is added to the  
CONFIG.SYS file and one to the AUTOEXEC.BAT  
file.  
6. If you are using the CD-ROM drive in an MS-DOS  
environment, the utility MSCDEX.EXE must also be

After the W6-LI system board and all hardware is in-  
stalled, the system is ready for configuration. Before  
turning on the computer, make sure all cables are cor-  
rectly connected and all jumpers are correctly set.  
It is recommended you keep the computer cover off the  
first time you boot the system. This will make it easier to  
correct any difficulties that might arise.  
Initial Boot Up  
Power up the W6-LI. If the system does not properly  
boot, check all your cables and peripherals for bad  
connections. You may also get beep codes or error  
messages. If this occurs, consult Appendices B and/or C  
for a guide to possible solutions.  
After the system properly boots, it is ready to be config-  
ured. The following information explains the proper  
procedures for BIOS configuration.  
Setup  
The Setup program is used to configure the computer’s  
BIOS (Basic Input/Output System). The computer’s  
BIOS is responsible for configuring the system board and  
providing hardware information to the operating system.  
In order for the computer to run properly, run the Setup  
procedure after first installing the system board and  
whenever you make a hardware change to the system.

Chapter  
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.  
5
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 ex-  
ternal 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 infor-  
mation, please contact the sound driver manufacturer.)  
3. Start your computer system.  
51  
W6-LI System Board Manual  
 
Chapter 5: Installing Device Drivers  
4. Insert the sound driver disk into your floppy drive.  
5. If you are using Windows 3.1x, go to the Program Man-  
ager File menu, click on Run and type A:\SETUP.  
6. If you are using Windows 95, refer to the Windows 95  
user’s manual for instructions on how to install sound  
drivers.  
7. If you are using OS/2, refer to the README file on  
the OS/2 disk for instructions on how to install sound  
drivers.  
8. Once the software is copied, the install program  
automatically updates the system files.  
Installing the SCSI Drivers  
Refer to the "Adaptec 7800 Family Manager Set User's  
Guide" for information on installing and configuring  
drivers for your operating 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 tonesare not described in the tables on the  
following pages.  
C
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 1-3-  
3 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  
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:  
E
1) AfterdownloadingtheappropriateBIOSfilefromour  
BBSorWebsite,extractittoabootableMS-DOS6.X  
diskette.  
2) Reboot your system with the MS-DOS 6.X diskette  
in the A: drive. To make sure a clean DOS environ-  
ment is loaded, press the F5 key while “Starting MS-  
DOS” 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:  
If you  
encounter  
any  
PHLASH W6LI_01.ROM [ENTER]  
problems  
duringthis  
process, or  
if you have  
questions  
aboutthe  
procedure,  
pleasecall  
Technical  
Support.  
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 proce-  
dure, please call Technical Support.  
NOTE:IftheBIOSissomehowerasedordoesnotseemto
