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.

• 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.

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

❏

A grounded power outlet

❏

Phillips-head screwdriver

❏

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.

RU

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.

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.



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.

SIMM Modules

The memory in this system can be increased to a maximum of 256MB by installing SIMMs (single in-line memory modules). To install SIMMs, first locate the memory banks on the system board (refer to Figure 2-1). Follow figure 2-

11 on page 2-14 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 SIMM Modules

The Millennia X

RU

has four 36-bit (72-pin) SIMM sockets onboard and can accommodate memory from 8MB up to 256MB using the following SIMM sizes:

4MB - organized as 1MB x 32 or 1MB x 36





The system board requires at least two SIMM sockets (one bank) to be filled.

Start with filling bank 0, then fill bank 1. The SIMMs must be rated at 50ns or

Step 1:

Using both hands, carefully set the SIMM into the socket at a 45

degree angle,

tilted towards the CPU socket (refer to Figures 2-8 and 2-9).

Do not force it in or damage may result. Note that the SIMM modules are keyed in such a way that they cannot be inserted incorrectly (refer to Figure

2-10 on page 13). 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 silver locking tabs (on the ends of the socket) are locked properly.

Step 3:

Using both hands and applying equal pressure on each end of the module, lock the module into the socket by pushing forward. Make sure both locking tabs have seated properly. The module should now be standing upright in the socket .

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

Removing SIMM Modules

To remove SIMM modules, simply reverse the above procedure with the following differences. Using the thumbs of both hands, gently pry the locking tabs apart so they no longer hold the module in the socket. While holding the tabs apart, gently pull the module backward to clear the tabs (this should put the module at an angle to the socket). Carefully remove the loose module from the socket.

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.



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:

Figure 3-1. Power-Up Screen

When “Press <F1> to enter SETUP” appears in the middle of the screen, press the <F1> key to begin the Setup procedure. The CMOS Main Screen (Figure 3-

2) should appear. The Setup procedure can only be activated during the boot sequence.

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

❏

The power cable is unplugged or defective.

❏

Voltage switch is improperly set.

❏

No power at outlet.

❏

Bad power supply.

Solution Checklist

❏

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.

❏

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).

❏

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

❏

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.



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

❏

The monitor may not be turned on or plugged in.

❏

A peripheral card may not be seated correctly on the system board.

❏

A peripheral card may be defective.

❏

A floppy drive may be defective.


❏

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.

❏

Carefully open the system unit. Press down firmly on all peripherals in the expansion slots.

❏

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.

❏

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.

❏

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

❏

Hard drive is incorrectly set up in CMOS.

❏

Hard drive cable may not be properly connected.

❏

CMOS may have lost settings.

❏

SCSI controller card may have lost settings.

❏

Files on hard drive may be corrupted.

❏

Hard drive may be defective.


❏

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.

❏

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 to the ADVANCED section of CMOS and press <Enter> on the line that says PERIPHERAL CONFIGURATION. Press <Enter> again and select AUTO. Exit and save your changes.

❏

With the power OFF, carefully open the system unit. Reset the gray ribbon cable that is connected to the hard drive and to the 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.



Problem

The system displays the error message “Non-system Disk or Disk

Error” or “Operating System Not found.”

Possible Cause

❏

The System files are missing from the Boot Sector of the hard drive.

❏

The diskette in Drive A: is not bootable.

❏

CMOS is incorrectly configured.


❏

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.

❏

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.

❏

If you boot to a setup utility, exit out so that your computer is at the A: prompt. From the A:\ prompt type SYS C:\ and press the

<Enter> key. Remove the Boot Diskette and reboot your system by pressing the Reset button on the front of your PC.

PERIPHERAL CONFIGURATION mode is set to Auto. For help in getting to your CMOS settings, see Chapter 3 - The BIOS Setup

Program.

❏

With the power OFF, carefully open the system unit. Reconnect the CD-ROM ribbon cable on the motherboard and at the back of the CD-ROM. 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 drives. Also, check to ensure that the power connector in the CD-ROM is secure.



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

❏

System CMOS has been reset to defaults, and you have a modem installed on COM 2.


❏

Check that the modem settings are set correctly and not conflicting with any other devices.

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.

❏

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.

Possible Causes

❏

Interference

❏

Invalid or corrupt video drivers.


❏

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.

❏

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.

Problem

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

Possible Cause

❏

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.

❏

When installing the new card, a different peripheral card or a cable may have been knocked loose.


❏

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.

❏

Double check all the gray ribbon cables and power connectors to ensure that they are plugged in correctly and securely.

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

Possible Cause

❏

The connections between the drive and the controller may be defective or loose.

❏

The hard drive’s root directory or file allocation table may be corrupted. The controller or hard drive may also be defective.


❏

Check that the hard drive and controller are connected properly.

❏

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.

Problem

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

Possible Cause

❏

The format may be fading.

❏

The hard drive may be developing media errors.

❏

The file allocation table may be corrupted.


❏

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.

Appendix D: Installing Sound Drivers

Installing Sound Device Drivers

This explains how to install the sound drivers necessary to utilize the onboard sound support. Prior to installing any drivers, follow the instructions on how to install a CD-ROM drive and how to connect external sound devices.

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.

WARNING:

This installation procedure should only be used if your hard drive has been re-formatted. These drivers have been installed at the factory and do not need to be reinstalled on a new system.

Installing the Sound Drivers

Once you have connected your external sound devices, you can install the sound drivers. If you are installing a CD-ROM drive, it is recommended you install it before setting up the sound devices.

1.

If you previously installed another sound card, remove it and all associated files from your AUTOEXEC.BAT and CONFIG.SYS

files.

2.

Start your computer system.

3.

Insert the sound driver disk into your floppy drive.

4.

From the DOS prompt (C:\), type: A:\INSTALL

5.

Follow the on-screen instructions and the installation program will automatically copy the drivers to your hard drive.

6.

Once the software is copied, the install program automatically updates your CONFIG.SYS and AUTOEXEC.BAT files.
