Ergonomic Notice

Now that you have your Micron computer, you will probably spend many
hours exploring the capabilities of this machine, and personalizing it for your
use. But the computer is only part of the larger picture of ergonomics.
Ergonomics is a science that addresses human performance and well-being in
relation to various types of jobs, tools, equipment and environment.

As you begin to personalize your working environment, it is important to
keep in mind your body’s needs to make your computer time more productive
with less physical and mental stress. And an effective work area will begin
from the ground up. Here are some suggestions:

• Use an adjustable chair, and try different seated postures to find

what is most comfortable and produces the least fatigue. The
backrest should be adjustable to fit the small of your back.

• Use an adjustable keyboard support. You want to keep your

wrists straight, your hands lower than your forearms and your
forearms parallel to the floor. Use a light touch on the keyboard.

• Alternate mouse and keyboard use, and keep the mouse within

easy reach.

• Place the monitor 18-30 inches from your eyes (arm’s length is

also a good distance). The top of the monitor should be level
with your eyes.

• Take breaks from both the keyboard and looking at the monitor.

Performing simple exercises while at your work area will increase
your productivity. Shrug your shoulders...take a deep

breath...change your focus...massage your hands...stretch....let

your arms fall relaxed at your sides.

No two work areas will ever be the same. Find the combinations that work for
you, and keep in mind that proper work area planning will make your
computer time more effective, and less stressful on your body.

Unpacking

Check the Packaging

As soon as the packages containing your new system arrive, carefully inspect
them for any signs of damage. In particular, look for wrinkled or bent corners,
holes, or other signs of bad handling or abuse. If you notice any damage to the
packaging, immediately open the boxes and inspect the contents for damage.
Pay close attention to the components near the area where the packing material
was damaged.

Unpack Your System

Caution: If your system arrives in cold weather, do not unpack the computer
or the monitor until they have been allowed to come to room temperature.
Immediately exposing them to the warm room may cause condensation to
occur, which may damage the units. If condensation does occur, allow the
units to completely dry before operating them.

Follow these steps after you have determined that the packaging is undamaged:

1. Taking care not to damage the packing material, carefully open
the cardboard box containing the computer and remove the
system unit, keyboard and any other accessories that you may
have ordered.

2. Carefully unpack the monitor and all accessories from the
monitor package. Be careful not to damage the packing material.

3. Inspect all items for damage that may have occurred during
shipment.

For your protection, report any damage to the shipper
immediately.

We highly recommend that you save the packaging in the event that you need
to move or ship the system some time in the future.

Check Your Packing List

Now that you have everything out of the packages, take the time to check the
packing list to be sure you received everything. If you discover that an item is
missing, call Micron Electronics, Inc. immediately to receive a replacement.
Refer to Appendix A for contact information.

Chapter 1: Setting Up Your System

Setup

Getting Started

Before your new system left the factory, Micron configured the hardware. The
display adapter was set to work with your monitor and the hard disk was
partitioned and formatted with DOS using the standard default settings for
your machine. Your computer system is ready to go. All you have to do is
plug it in.

What You Need

o A grounded power outlet
o Phillips-head screwdriver
o Power filter/suppressor protector (recommended)

Putting It All Together

To complete your setup, refer to the following steps:

1. Take a moment and review the case figures on the following

pages to acquaint yourself with the front and back of your system.

2. Check the voltage selector on the rear of the unit. Be sure it is

switched for the proper voltage (115V in the United States and
Canada).

3. Place the monitor where you wish, as long as its cable can still

reach the video connector at the rear of the computer.

4. Unpack the power cable for the computer and plug the

appropriate end into the power inlet at the back of the system.
Insert the other end into a grounded power outlet. We highly
recommend that you obtain a protection device such as an
uninterruptable power supply (UPS), power filter or surge
suppressor. In this way you will be providing the utmost
protection for your system and data.

5. Ensure that the system is turned OFF before proceeding.

Attaching peripherals while the power is on may damage the
unit or the peripheral.

6. Locate the monitor’s power cable and plug the appropriate end

into the monitor (if not already attached). Insert the other end
into the grounded outlet or protection device.

Micron Electronics, Inc. 1-3

Micron ClientPro 766Xi/Xe User’s Guide

7. Find the video cable and attach the appropriate end into the
monitor (if not already attached) and attach the other end into
the video connector (located in one of the expansion slots at the
rear of the unit). If the connection is loose on either end, tighten
the integrated screws at both ends of the cable for a secure
connection. For more information about the setup, use, and
maintenance of your video monitor, please refer to the manual
that was supplied with it.

8. Insert the ends of the keyboard and mouse cables into the
keyboard and mouse connectors at the rear of the computer
system. Take care, for the connectors are keyed in such a way
that the plugs can only be inserted if oriented correctly. Refer to
the case drawings on the following pages for the location of the
proper connector. If it does not plug in easily, do not force it.

Your system should now be ready to use. You may have other devices or
peripherals to install, but it is best to ensure the basic system is operating
correctly before adding any options.

Chapter 1: Setting Up Your System

Running Your System for the First Time

1. Power up the monitor. If you are unsure about this, please refer

to the monitor’s manual for more information.

2. Remove any floppy disks from the floppy drive.

3. Power up the computer system by firmly pushing and releasing

the On/Off button on the front panel of the system. The power
indicator should light up and the fan and hard drive should begin
to run.

The system diagnostics begins at this time. The keyboard is initialized indicated
by the keyboard LEDs blinking momentarily. The Num Lock LED remains
on. Next, the screen initializes and a message indicating what type of video
adapter is installed. The memory will be counted and tested.

Finally, the system is booted.

If you experience any problems during the power up sequence, please refer to Chapter
4, "Common Problems."

Turning Off Your System

Micron recommends that you power down your system in the following order:

1. Exit all applications you are running and save any changes.

2. Make sure that ALL disk activity has completely stopped. The

floppy and hard drive indicator lights should be off and the
floppy drive motors should stop. Hard disks continue to spin
until the system power is shut off.

3. Turn off the computer system, then the monitor.

Micron Electronics, Inc. 1-11

Micron ClientPro 766Xi/Xe User’s Guide

Maintenance

Operating Environment

Your Micron computer has been manufactured to the highest standards. With
proper care, it should provide years of trouble-free service.

To ensure that your system has the longest life possible, it should be placed in
an area with good ventilation and low humidity, out of direct sunlight and
away from heat sources or lamps. Be sure the rear cooling-fan opening is not
obstructed as it is necessary to keep the system cool. Never expose the system
to any moisture. This could lead to fire or shock hazard. Stay away from areas
with high levels of dust, dirt, or smoke.

Transporting

Always shut the system off before moving it. Any sudden jar or shock may
permanently damage the hard drive. Hard drives are more resistant to shock
if they are shut down.

If you are transporting the system over a distance, it is a good idea to completely
repackage it in its original packing material. If the original packaging is
unavailable, pack all components with as much padding as reasonably possible
to ensure that the units are not exposed to excessive vibration or shock.

Cleaning

If the case becomes dirty through constant use or handling, use only a damp,
dust-free cloth for cleaning. Do not use abrasives or solvents as these may mar
or scratch the case. Window cleaner and a cloth can be used to clean the monitor,
if the monitor has been turned OFF first. Never apply the window cleaner
directly to the monitor screen. Always spray the cloth first, then wipe down
the screen.

Cleaning kits designed to clean floppy drives are available from most computer
stores and should be used periodically.

If you are operating your system in an environment heavy with smoke or
dust, you should occasionally open the unit and with great care, clean the
components with a vacuum (special vacuums are available just for this
purpose). Be careful to not loosen any of the components.

If liquid is spilled into the keyboard, immediately unplug it, allow the fluid to
drain out by tipping the keyboard upside down, and dry the keyboard
overnight before using it again.

1-12 Micron Electronics, Inc.

Chapter 1: Setting Up Your System

Protecting

To prevent normal electrical problems such as spikes or surges, install a power
surge/filter between the power outlet and all of the connected components. If
even one component is not connected, the entire system could be at risk.

If a severe storm enters your area, completely unplug the entire system from
all electrical sources, including phone lines. Lightning can travel in on any
line and destroy all connected components.

If possible, do not turn the system on and off frequently. This stresses the
power supply and may shorten the life of some components. To restart the
system, press the reset button located in the front of the case. If applications
are open and the system is reset or if the hard drive is active, data loss will
most certainly occur. If you do not use the reset button to restart the system, be
sure the hard drive has come to a complete stop before turning the computer
on again.

Backing Up

Even with today’s technology, data loss can occur at any time. We highly
recommend that you back-up often. There are a large number of backup systems
available from retail and mail-order outlets, including floppy drive backup
systems, tape backup systems, and optical backup systems. Any of these
alternatives are highly recommended. Complete, frequent backups can save
years of data from total and irretrievable destruction. If you require additional
information about backup systems or options, please contact Micron
Electronics, Inc.

Micron ClientPro 766Xi/Xe User’s Guide

Installing Add-On Peripherals

The ClientPro 766Xi/Xe accommodates ISA and PCI Local Bus cards. Extra
SDRAM can also be added to the system board. The following describes how
to install the PCI card and SDRAM memory.

PCI Local Bus Card

PCI Local Bus slots accommodate most PCI-approved Local Bus cards. To install
a PCI Local Bus card:

1. Power OFF the computer system.

2. Locate an unused PCI slot on the system board.

3. Insert the card with the bottom edge level. Never insert the card
at an angle.

4. Holding the card at the center of the top edge, gently push straight
in. Do not force the card into place. If it does not fit, take it out
and try again.

5. Make sure the card is fully inserted.

6. Secure the card with a bracket screw.

Accelerated Graphics Port

The ClientPro 766Xi/Xe also comes with an Accelerated Graphics Port (AGP).
This is a high-performance interconnect for graphic-intensive applications,
such as working with 3D graphics. AGP is independent of the PCI bus and is
intended for exclusive use with graphical-display devices. AGP provides these
performance features:

• Pipelined-memory read and write operations that hide memory
access latency.

• Demultiplexing of address and data on the bus for near-100%
efficiency.

• AC timing for 133MHz data transfer rates, allowing data
throughput of 500 MB per second.

AGP complies with the 66MHz PCI specification.

Chapter 2: Technical Information

Figure 2-6. Installing a PCI Local Bus Card

NOTE: The ISA slot (J4B2) and the PCI slot (J4B1) are “shared slots.” When a
PCI card is installed into the (J4B1) PCI slot, the (J4B2) ISA slot is disabled.
Conversely, when a peripheral card is installed into the (J4B2) ISA slot, the
(J4B1) PCI slot is disabled.

DIMM Modules

The memory in this system can be increased up to a maximum of 384MB by
installing DIMMs (dual in-line memory modules). To install DIMMs, first locate
the memory banks on the system board (refer to Figure 2-1). Follow the table
on page 2-3 for the possible installation combinations.

CAUTION: Modules are Electrostatic Sensitive.

Even a small electrostatic discharge could damage the module. A damaged
module might not fail immediately, but over time it will become worse,
possibly causing an "intermittent" problem. Be very careful to handle the
boards ONLY by the edges. DO NOT touch the gold/silver edge-connectors
or any of the components on the board. Leave the module in the antistatic
bag until ready for installation.

1. Switch the computer off. Leave the computer plugged in to the
outlet to provide an electrical ground to discharge static
electricity.

2. Touch the metal case of the power supply or the metal lining
inside the computer case. This will drain the static charge from
your body and will keep the modules from being electrically
damaged.

3. Keep body movement to a minimum as you remove and handle
the modules. Antistatic wrist straps with clip-on ends are
commercially available.

Installing DIMM Modules

The ClientPro 766Xi/Xe has three, 168-pin DIMM sockets on-board and can
accommodate ECC or non-ECC SDRAM memory from 8MB up to 348MB using
the DIMM combinations on page 2-3.

There are no jumper settings required for the memory size or type, which is
automatically detected by the system BIOS. Gold leaded DlMMs are required
to be used when adding system memory.

2-10 Micron Electronics, Inc.

Chapter 2: Technical Information

Step 1: Using both hands, carefully set the DIMM into the center of
the left and right latching levers. Center the module over the socket
so that the notches are aligned with the socket keys. Do not force it in
or damage may result. Note that the DIMM modules are keyed in
such a way that they cannot be inserted incorrectly (refer to the
figure below). If you are having difficulty placing them into the
socket, check to see that you are not attempting to insert them
backwards.

Do not lock the module into position at this time.

Step 2: Check to make sure the module is centered in the socket, and

that the connector pins of the module line up with the socket connector
pins.

A) Be sure the module is centered and connector pins are

aligned.

B) When the module is locked in place, be sure both latching

levers are fully seated into latching notches in the sides of
the DIMMs.

Step 3: Using both hands and applying equal pressure on each end
of the module, lock the module into the socket by pushing downward
with the thumbs and squeezing inward with the forefingers. Make
sure both latching levers have seated fully into the modules latching
notch. The module should now be standing upright in the socket.
Refer to the fully seated drawing on the following page.

WARNING: Failure to observe proper insertion guidelines may result in damage
to the DIMM and/or the socket.

Figure 2-7. Proper DIMM Insertion

Micron Electronics, Inc. 2-11

Micron ClientPro 766Xi/Xe User’s Guide

Figure 2-8. DIMM Fully Seated

Removing DIMM Modules

To remove DIMM modules, simply reverse the installation procedure with
the following differences. Using the thumbs of both hands, gently pry the
latching levers open so they no longer hold the module in the socket. Gently
lift the module upward to clear the latching levers.

SETUP

BIOS Setup

Every AT-compatible computer has a battery supported CMOS memory
location that stores information about the system and peripheral configuration.
Because of the attached battery, the CMOS is constantly provided with power,
even when the computer has been turned off.

During the boot sequence, a special software application called the BIOS (Basic
Input Output System), located in read-only memory (ROM) on the system
board, reads the information contained in the CMOS and configures the CPU
and other peripheral devices. If the CMOS information is incorrect, the system
may not operate correctly until accurate information is stored in the CMOS.
The Setup program has been built into the system to provide the means for
changing the CMOS.

When Setup Should Be Run

Although your system arrives fully configured, the system may need to be
adjusted to fit your needs.

Whenever peripherals are added or removed from the system (for example, if
you add a hard disk or more memory), you must run Setup to inform the
system about the new configuration.

If the information in CMOS is lost, the system will not operate properly unless
Setup is used to restore the system configuration.

3-2 Micron Electronics, Inc.

Chapter 3: The BIOS Setup Program

How to Run the Setup Program

The Setup program is used to configure the computer’s BIOS (Basic Input/
Output System). The computer’s BIOS is responsible for configuring the
motherboard 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.

After the system is turned on and goes through a memory test, the Power-Up
Screen (Figure 3-1) appears on your monitor:

When “Press <F2> to enter SETUP” appears in the bottom of the screen, press
the <F2> key to begin the Setup procedure. The CMOS Main Screen (Figure 3-

Introduction

Occasionally while setting up and configuring a computer system, an error
may occur or an important element may be forgotten. This section provides
information regarding the most frequently encountered problems, as well as
many quick and simple solutions. If you continue to experience problems and
this section fails to provide solutions, please feel free to contact Micron technical
support (see Appendix A: Contacting Technical Support).

Problems During Boot

Problem

When the power switch is turned on, the system does not power up
(i.e., the exhaust fan does not run, the power indicator light is not
illuminated, the hard disk does not begin to spin, etc.), and no audible
"beep" is heard.

Possible Cause

o The power cable is unplugged or defective.
o Voltage switch is improperly set.
o No power at outlet.
o Bad power supply.

Solution Checklist

o Check to ensure the power cable is plugged in correctly and

firmly. Try a second power cable, if available, or test the cable
for continuity. Replace original cable if it is found to be defective.

o Check the red voltage switch (located at the rear of the unit near

the fan) and ensure that it is set for the proper voltage (115V in
the U.S. and Canada).

o Check the outlet with another appliance (e.g., a lamp).

o If a surge suppressor or Uninterruptable Power Supply (UPS) is

being used, temporarily bypass the surge suppressor and plug
the unit directly into the wall outlet. The surge suppressor or
UPS may be faulty.

4-2 Micron Electronics, Inc.

Problem

When the power switch is turned on, the system has power (i.e., the
exhaust fan runs, the power indicator light is illuminated, the hard
disk begins to spin, etc.), but the system appears dead. Generally the
keyboard LEDs will stay on.

Possible Cause

o The monitor may not be turned on or plugged in.
o A peripheral card may not be seated correctly on the system

board.

o A peripheral card may be defective.
o A floppy drive may be defective.

Solution Checklist

o Check to make sure the monitor power cable is plugged into the

wall outlet and the back of the monitor. Also verify the monitor
video cable is plugged into the video card in the back of the
computer. Check the monitor to ensure that the power is on. If
you suspect a problem with the monitor, please refer to the
manual that was provided with it.

o Carefully open the system unit. Press down firmly on all

peripherals in the expansion slots.

o With the system power shut off, remove one peripheral card,

power up the system, and wait a few moments to see if the
keyboard lights turn off. If they don’t turn off, repeat the above
steps with the next peripheral card until all have been removed.
After this has been completed, contact Micron technical support
for further assistance.

Chapter 4: Common Problems

o With the system power shut off, completely disconnect one of

the floppy drives and power up the system. If the keyboard lights
do not turn off after a few moments, repeat the above procedure
until all drives are disconnected. After this has been completed,
contact Micron technical support for further assistance.

o Contact Micron technical support if none of the above procedures

is effective.

Problem

System powers on, the display works, but the system does not
complete the boot process or you see one of the following error
messages:

“Hard Disk Controller Failure.”
“Fixed Disk Configuration Error.”
“Operating System Not Found.”

Possible Cause

o Hard drive is incorrectly set up in CMOS.
o Hard drive cable may not be properly connected.
o CMOS may have lost settings.
o SCSI controller card may have lost settings.
o Files on hard drive may be corrupted.
o Hard drive may be defective.

Solution Checklist

o If you have a SCSI hard drive, make sure that the CMOS says

Not Installed for all hard disk drives. For help in getting to your
CMOS settings, see Chapter 3 - The BIOS Setup Program.

o For an IDE drive - check the parameters of the hard drive. Have

the system re-Autodetect the settings of the drive. To do this,
highlight the first hard disk from the MAIN screen of your CMOS
Setup (labeled Primary IDE Master) and press the <Enter> key.
On the next screen press <Enter> again and select AUTO
CONFIGURED. Press <Enter> and the system should reassign
the proper values to the hard drive. You will also want to make
sure that the primary IDE controller is enabled. To verify, move

motherboard or SCSI Controller Card. To assist you, the colored
stripe going down the side of the gray controller cable signifies
pin one and should be connected to pin one of the controller and
drive. Also, check to ensure that the power connector in the Hard
Drive is secure. Power the system back up and perform an
AUTODETECT of the hard drive again.

4-4 Micron Electronics, Inc.

Problem

The system displays the error message “Non-system Disk or Disk
Error” or “Operating System Not found.”

Possible Cause

o The System files are missing from the Boot Sector of the hard

drive.

o The diskette in Drive A: is not bootable.
o CMOS is incorrectly configured.

Solution Checklist

o Your system is designed to first check the floppy drive for a

bootable diskette. If there is a diskette in the floppy drive when
you reset your system the above error message will appear unless
the diskette is a bootable system diskette. Remove the diskette
from drive A: and reboot your computer. If the computer still
does not boot up, you may have to restore system files to the
hard drive.

o To restore system files:

Make sure your hard drive information is correct in CMOS (see
above for help in correctly setting up your CMOS). Insert the
DOS or Windows 95 Boot Diskette provided with your Micron
system and either reset or power on your system with the disk
in the floppy drive.

Problem

The system displays the error message COM Port 2F8 conflict during
boot, or the system beeps, and displays the message “Press F1 to
Continue, F2 for Setup.”

Possible Cause

o System CMOS has been reset to defaults, and you have a modem

installed on COM 2.

Solution Checklist

o Check that the modem settings are set correctly and not

conflicting with any other devices.

o If you are using Windows 95™ and the CMOS is set correctly,

remove the checkmark from Use Original Configuration
(Current) under the properties section for your Communications
Port (Com 4) in device manager. Then, remove your modem from
device manager and have the Windows 95™ operating system
re-detect your modem.

Problem

The monitor is flickering noticeably or the video is distorted.

Chapter 4: Common Problems

On Windows 95™ systems Serial/Com Port B should be set
to COM 4. For DOS and Windows for Workgroups™, Serial/
Com Port B should be set to Disabled or None. For help on
CMOS settings, refer to Chapter 3- The BIOS Setup Program.

Possible Causes

o Interference
o Invalid or corrupt video drivers.

Solution Checklist

o Check for high power-draining devices, or high noise devices in

the area. Examples include heaters, air conditioners, other
monitors, other computers, fluorescent lights, printers,
microwaves, or televisions. Any of these devices could cause a
flickering in your display because of the interference they can
put into the power lines or the environment. Also, temporarily
unplug any other devices that are in the same outlet or surge
protector that the monitor and computer are using. This could
be amplified speakers, or one of the devices listed above.

o Temporarily switch your video display to use default standard

VGA drivers. Your display will not have the clarity or color
definition that it usually does, however, check to see if everything
appears normal. If it does, try reinstalling the video drivers
specific to your video card that shipped with your system, or
check the Micron Electronics Internet Site for updated video
drivers.

Micron Electronics, Inc. 4-7

Problem

After installing a new peripheral card, an unrelated part of the system
suddenly stops working.

Possible Cause

o The new card may be attempting to use some of the same system

resources, such as address space, I/O ports, interrupt lines, etc.,
and may be conflicting with the failing part of the system.

o When installing the new card, a different peripheral card or a

cable may have been knocked loose.

Solution Checklist

o Remove the new card and retry system.

If it works, you will need to change the I/O ports, interrupt lines
or address regions the new card uses. Most cards have jumpers
or switches that can be changed to reconfigure the settings. Refer
to the documentation that came with the card to determine how
to change the settings. If you have any questions, contact the
card’s manufacturer.

o Double check all the gray ribbon cables and power connectors to

ensure that they are plugged in correctly and securely.

Hard Disk Problems

Problem

System has to be booted from a floppy disk. Hard drive is either
unrecognized or unreadable.

Possible Cause

o The connections between the drive and the controller may be

defective or loose.

o The hard drive’s root directory or file allocation table may be

corrupted. The controller or hard drive may also be defective.

Solution Checklist

o Check that the hard drive and controller are connected properly.

o If hard drive recovery software is available, use it to repair the

damage. The only other solution is to attempt a high-level (DOS)
format on the drive.

Do not attempt to low-level format the drive!

If the drive cannot be formatted, either the drive or the controller
may be defective. Contact Micron technical support.

Chapter 4: Common Problems

Problem

System has to be booted from a floppy disk. Hard disk is completely
functional, but cannot be used for boot-up.

Possible Cause

o The hard drive’s boot sector may be corrupted.

Solution Checklist

o If hard drive recovery software is available, attempt to use it to

repair the damaged boot sector. The only other solution is to
attempt a high-level (DOS) format on the drive and transfer the
DOS system to the boot sector.

Do not attempt to low-level format the drive!

Backup your data before formatting your drive.

Micron Electronics, Inc. 4-9

Micron ClientPro 766Xi/Xe User’s Guide

Problem

Read/write, sector, data, or seek errors occur when attempting to
access files on the hard drive.

Possible Cause

o The format may be fading.
o The hard drive may be developing media errors.
o The file allocation table may be corrupted.

Solution Checklist

o Using a file-by-file backup method, backup as much data as you

can, then reformat the drive. If the format is successful, use a
disk diagnostic software application to test the media of the drive
(make sure the application locks out any errors it finds to make
them inaccessible from DOS). Finally, restore your files from the
backup tape or diskettes.
