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

❏ 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.

Micron Electronics, Inc. 1-3

Micron NetFRAME LV2000 Server System 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. 1-7

Micron NetFRAME LV2000 Server System 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.

1-8 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 Electronics, Inc. 1-9

Micron NetFRAME LV2000 Server System User’s Guide

Removing the System Cover

Refer to the Figure on page 1-13. Use a #2 Phillips-head screwdriver or a 1/4"
hex driver.

1 . It is not necessary to disconnect the cable connectors on the back

of the computer before opening the cover. However, note where
the cables connect to the back for future reference . (If you have
a video camera, a quick scan of the rear case is helpful).

2 . Remove the screws from the back of the case cover. Keep these

screws together (they are a different size than the other screws
in your system) for they are not to be interchanged.

3 . With flat palms placed on each side of the cover, pull the cover

back until the cover's front top lip clears the chassis channel
(about 3/4"). Grasp the top-rear of the cover and lift up in one
smooth motion until the cover clears the chassis.

To replace the cover, gently lower the top lip of the cover into the chassis
channel at an angle before lowering the rear into place. With the lip inserted
in the channel, push the rear of the cover forward to seat it flush and replace
the screws. Note the metal rail guides located inside the bottom of the cover
which must fit over the bottom metal case frame when the cover is replaced.

2-14 Micron Electronics, Inc.

Chapter 2: Technical Information

DIMM Modules

The memory in this system can be increased up to a maximum of 512MB 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 2-14 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 DIMM Modules

The NetFRAME LV2000 has four, 72-pin DIMM sockets on-board and can
accommodate ECC or non-ECC SDRAM memory from 32MB up to 512MB
using the DIMM combinations on page 2-14.

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

Micron Electronics, Inc. 2-15

Micron NetFRAME LV2000 Server System User’s Guide

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.

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 (ROM) memory 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 the Micron NetFRAME LV2000 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: Configuring the System

Power-on Self Test (POST)

Each time you turn on the system, POST starts running. POST checks the
system board, processor, memory, keyboard, and most installed peripheral
devices. During the memory test, POST displays the amount of memory that
it is able to access and test. The length of time needed to test memory depends
on the amount of memory installed. POST is stored in flash memory.

1 . Turn on your video monitor and system. After a few seconds

POST begins to run.
2 . After the memory test, these screen prompts and messages

appear:

Press <F2> key if you want to run SETUP

Keyboard.....Detected

Mouse........Detected

3. If you do not press <F2> and do NOT have a device with an

operating system loaded, the above message remains for a few

seconds while the boot process continues, and the system beeps

once. Then this message appears:

Insert bootable media in the appropriate drive

If you do not press <F2> and DO have an operating system

loaded, the boot process continues, and this message appears:

Press <Ctrl><A> for SCSISelect(TM) Utility!

4 . Press <Ctrl+A> if there are SCSI devices installed. When the

utility opens, follow the displayed instructions to configure the

onboard Adaptec AIC-7880 Ultra-wide SCSI host adapter settings

and to run the SCSI utilities.

If you choose not to press <Ctrl><A> (SCSISelect Utility), the

boot process continues. After POST completes, the system beeps

once.

What appears on the screen after this depends on whether you have an
operating system loaded and if so, which one.

If the system halts before POST completes running, it emits a beep code
indicating a fatal system error that requires immediate attention. If POST can
display a message on the video display screen, it causes the speaker to beep
twice as the message appears.

Note the screen display and write down the beep code you hear; this
information is useful for your service representative. For a listing of beep
codes and error messages that POST can generate, see the “Solving Problems”
chapter in this manual.

Micron Electronics, Inc. 3-3

Micron NetFRAME LV2000 Server System User’s Guide

Using the System Configuration Utility (SCU)

The System Configuration Utility (SCU) is the main tool to configure the system
or to check or change the configuration. Many system settings can be entered
from either the SCU or Setup, but the SCU provides conflict resolution as well
as access to information about ISA, ISA Plug and Play, and PCI adapters. The
SCU is PCI-aware, and it complies with the ISA Plug and Play specifications.
The SCU works with any compliant configuration (.CFG) or overlay (.OVL)
files supplied by a peripheral device manufacturer.

System must have a diskette drive

The system must have a diskette drive present and enabled to use
the SCU. If a diskette drive is present but is disabled or misconfigured,
use the BIOS Setup utility to enable or configure the drive.

Where the SCU Gets Information

Source Description

Configuration (.CFG) For the system board, we provide a .CFG file

and overlay (.OVL) files

and an .OVL file with the SCU. These files
describe the board’s characteristics and the
system resources required. Some ISA adapters
come with a diskette that contains a .CFG file
(and an optional .OVL file).

Configuration registers Information and required resources for PCI

and Plug and Play adapters are derived from
the adapter’s configuration registers.

User selected options The SCU displays the exact system

configuration and the user’s current settings
by reading ISA CMOS and system nonvolatile
storage (NVRAM or flash memory).

Using information from the sources listed above, the SCU stores the system
configuration in ISA CMOS and system nonvolatile storage (NVRAM or flash
memory).

At power-on or rebooting, the BIOS POST routines and the Plug and Play
Auto Configuration Manager check and configure the hardware. If possible,
POST will program the hardware according to the configuration stored by the
SCU; if conflicts exist, an error message will be generated. You must then use
the SCU to correct the conflict before the system boots.

3-4 Micron Electronics, Inc.

Chapter 3: Configuring the System

When to Run the SCU

❏ When you first set up and configure the system
❏ If you get a configuration error message at power-on
❏ Whenever you add, remove, or move an ISA adapter that is not

Plug and Play

❏ Whenever you add or remove memory
❏ In general, whenever you add hardware to or remove hardware

from the system

Running the SCU is also recommended but optional for Plug and Play and
PCI adapters.

Record Your SCU Settings

Record your SCU settings. If the default values ever need to be restored (after
a CMOS-clear, for example), you must run the SCU to reconfigure your system.
Referring to the worksheets could make your task easier.

How to Enter and Start the SCU

Copy SCU to diskette

Before you can run the SCU from a diskette, you must copy the SCU
from the Configuration Software CD to a diskette.

1 . Turn on your video display monitor and system.
2 . You can enter and start the SCU in three different ways. Whether

or not you can use the second and third ways described in the

following table depends on how much main memory is used by

drivers loaded on the system.

Use diskette

Always start with a diskette that contains the SCU you copied from
the Configuration Software CD.

You can start the SCU from these sources:
How to do it:

From diskette at boot time.

Insert your SCU diskette in drive A. Press the reset button or type
<Ctrl+Alt+Del> to reboot the system.

Micron Electronics, Inc. 3-5

Micron NetFRAME LV2000 Server System User’s Guide

From diskette after installing your operating system.

Insert your SCU diskette in drive A. At the DOS prompt, type a: and
press <Enter> to change to drive A. Type AUTOEXEC and press
<Enter> to start the SCU.

From a hard drive after installing your operating system.

Insert your SCU diskette in drive A and copy the contents to a
directory on your hard drive. Change to that directory, and type
AUTOEXEC and press <Enter>.

SCU Utilities

At the bottom of the main SCU menu, there is an option to press <F9> to
display the Utilities menu. The menu lists options that control how a
configuration is produced. For most of these choices, select the option line
and press the spacebar to enable/disable the option.

For descriptions of the options, press <F1> for help while the Utilities menu
displays on the screen. Here is a little more information about some of the
utilities:

Advanced/Dealer Mode—some ISA boards can be shipped with configuration
files that contain options that are not ordinarily configured by end users. If
this mode is turned on, any functions marked as EXP (expert) in the shipped
configuration file will be visible and can be updated.

Force new configuration—this option forces the SCU to ignore any information
stored in the Extended System Configuration Data (ESCD) structure in
NVRAM. This means that any ISA boards will “disappear” and that PCI and
Plug and Play ISA settings will be reset.

Specify name for .cms, .inf, and .set files—this option prompts you for the
base filename for the .CMS, .INF, and .SET files. This allows you to save
configuration information into different filenames. Otherwise, each time a
save operation completes in the SCU, the .CMS, .INF, and .SET files will be
overwritten. In this system, the default base filename is int31e0, so when the
SCU is saved, the files int31e0.cms, int31e0.inf, and int31e0.set are created.

Press <F5> to restore a configuration from a CMS file—a .CMS file is created
each time you do a save operation in the SCU. The file contains a copy of the
ESCD image as it was stored into nonvolatile memory and can be used to
restore this information at a later time. If the configuration information is
accidentally erased or a mistake has been made during the configuration
process, it might be desirable to restore to a previous configuration. The backup
.CMS file provides this mechanism to restore the ESCD image.

Press <F7> to define an ISA board. If you have an ISA board with no .CFG file,
you can use the ISA Board Definition screen to define the board. (You can
access the same menu from SCU Step 2 by pressing <F6>.)

Automatic detection and enabling of IDE hard drives—during POST, if an
IDE controller is detected, the BIOS does the following:

❏ Determines the types of IDE drives attached
❏ Sets the drive parameters for the best performance
❏ Maps each device into memory and I/O space
❏ Assigns IRQs and DMA channels so there are no conflicts

If you choose parameters for your drive that are different from the drive’s
native parameters, your definitions will be programmed into the drive
controller.

To disable the IDE controller

If you plan to disable the IDE controller to reuse the interrupt for that controller,
you must physically unplug the IDE cable from the board connector (IDE0) if
a cable is present. Simply disabling the drive by configuring the SCU option
does not make the interrupt available for other use.

The options in the Management Subsystem Group are used to

❏ Set up system board voltage and temperature scanning by

determining the appropriate thresholds

❏ Enable or disable a system speaker
❏ Scan the flash memory area for binaries that extend or alter critical

event logging

This section does not list the sensors that will be displayed for configuring,
because the list depends on information provided by the system at run-time.
The information is placed in the system during manufacturing and assembly
and depends on the particular configuration of the system.

However, the user interface should be constant when viewed on a sensor-by­sensor basis. The screen gives prompts for how to select and modify values
and how to move around the screen. For each available sensor control, the
display includes the choices shown below, with blanks for entering values by
using the <+> or <-> keys (“+5 V supply” is shown here as an example):

In most cases, we recommend leaving the controls Enabled.
However, if you have an operating system that does not handle system

management interrupts, then you might want to disable the controls. When a
control is disabled, the sensor itself is still active and able to give valid readings,
but no system management interrupt will be generated. A server management
utility can collect the readings for information or comparison.

* Enable all three options if you are using server management software.
System Management Mode—if enabled, the embedded Server Management

firmware is loaded.
Event Logging—if event logging is enabled, the BIOS can log critical and
informational events to nonvolatile flash memory. Critical events are those
that normally result in the system being shut down to prevent catastrophic
side-effects from propagating to other parts of the system. These are example
events:

❏ Operating system outside of the range of set temperature and

voltage limits

❏ Multibit and parity errors in the memory subsystem
❏ Most errors that normally generate a Nonmaskable Interrupt

(NMI) (including I/O channel check, software generated NMI,

and PCI SERR events)

When such errors are detected, the system management interrupt (SMI)
routines log the error or event (transparently to the OS) and cause an NMI to
be generated for certain fatal events (for example, certain NMIs and
uncorrectable ECC errors).

If the OS device driver is using the watchdog timer to detect software or
hardware failures, and that timer happens to expire, an Asynchronous System
Reset (ASR) is generated. This is equivalent to a hard reset, except that the
limit registers are not reset. POST detects this event as the system reboots and
will log the event to the logging area.

PCI System Error Detection—when enabled, if a PCI bus error (SERR#) is
detected, a critical event is placed in the system event log and an NMI is
generated. Enabling this feature has no effect when SMM Mode or Event
Logging is disabled.

Server Management

The system board includes hardware components that process information
about system status and that monitor power supply voltages and operating
temperature. You can use server management software to send and log
messages about conditions reported if the system is not operating within
specified limits.

Some options are required by server management software

If you are using server management software, make sure you select these
options in the SCU and Setup; some of the options in the two utilities achieve
the same goal, although the menu text differs:

*To view an event log, you must have server management software installed.
**The SCU contains menus for entering sensor control values (thresholds), and the BIOS

will load defaults from the SCU. Note that server management software may include
its own menus for entering threshold values, and these values may overwrite the ones
you enter using the SCU menus. For details, refer to the manual that comes with your
server management software.

Using Setup

This section describes the BIOS Setup options. Use Setup to change the system
configuration defaults. You can run Setup with or without an operating system
being present. Setup stores most of the configuration values in battery-backed
CMOS; the rest of the values are stored in flash memory. The values take
effect when you boot the system. POST uses these values to configure the
hardware; if the values and the actual hardware do not agree, POST generates
an error message. You must then run Setup to specify the correct configuration.

Run Setup: you may run Setup to modify any standard PC AT= system board
feature such as:

❏ Select diskette drive
❏ Select parallel port
❏ Select serial port
❏ Set time/date (to be stored in RTC)
❏ Configure IDE hard drive
❏ Specify boot device sequence
❏ Enable SCSI BIOS

Run SCU, not Setup: you must run the SCU instead of Setup to do the
following:

❏ Add or remove any ISA board that is not Plug and Play-

compatible

❏ Enter or change information about a board
❏ Set system management threshold values
❏ Alter system resources (such as interrupts, memory addresses,

I/O assignments) to user-selected choices instead of choices

selected by the BIOS resource manager

❏ Specify new values whenever you add or remove memory

3-20 Micron Electronics, Inc.

Chapter 3: Configuring the System

If You Cannot Access Setup

If the diskette drive is misconfigured so that you cannot access it to run a
utility from a diskette, you may need to clear CMOS memory. You will need
to open the system, change a jumper setting, use Setup to check and set diskette
drive options, and change the jumper back. For a step-by-step procedure, see
Chapter 5, under the heading, “CMOS Jumper.”

How to Enter and Start Setup

You can enter and start Setup under several conditions:

❏ When you turn on the system, after POST completes the memory

test.

❏ When you reboot the system by pressing <Ctrl+Alt+Del> while

at the DOS operating system prompt.

❏ When you have moved the CMOS jumper on the system board

to the “Clear CMOS” position (enabled); for the procedure, see
Chapter 5, under the heading “CMOS Jumper.”

In the three conditions listed above, after rebooting, you will see this prompt:

Press <F2> to enter SETUP

If the <F2> prompt does not appear

If the <F2> prompt does not appear, the display of the prompt has been disabled
in the SCU. You can enter Setup anyway by pressing <F2> right after the
system memory size is shown.

For the procedure to enable the prompt, see Chapter 7 under the heading,
“Press <F2> Key to Enter Setup: Prompt Does Not Display.”

In a fourth condition, when CMOS/NVRAM has been corrupted, you will see
other prompts but not the <F2> prompt:

❏ Warning: cmos checksum invalid

❏ Warning: cmos time and date not set

In this condition, the BIOS will load default values for CMOS and attempt to
boot.

Host Adapter SCSI ID—Each device on the SCSI bus, including the adapter,
must have a unique ID. The ID defines the device, and the priority of the ID
determines which device controls the bus when two or more devices try to use
it at the same time. Each adapter on the bus, whether 8- or 16-bit, has a default
ID of 7, so the adapter always has the highest priority. This is the priority
model:

Device priority model Highest priority ID Lowest priority ID

8-bit devices (narrow SCSI) 7 0
16-bit devices (wide SCSI) 7 through 0 15 through 8
(In this case, ID 7 has the

highest priority and
ID 8 the lowest)

SCSI Parity Checking—when enabled, the host adapter uses SCSI parity
checking to verify the accuracy of data transfer on the SCSI bus. If a device on
the bus does not support SCSI parity, the option must be disabled.

Host Adapter SCSI Termination—the setting for this option is determined
by (1) the location of the host adapter on the bus and (2) whether the SCSI
devices connected to the bus are narrow, wide, or a combination. The bus
must have a set of resistors, called terminators, either installed in or enabled on
the first and last SCSI devices on the bus, or else data transfer may not be
accurate. The host adapter itself is the SCSI device at one end of the bus, and
termination on the adapter cannot be disabled. On a 16-bit adapter, termination
is enabled for both the low byte (bits 0-7) and the high byte (bits 8-15). If there
is no 8-bit adapter at the end of the bus, you must disable termination by using
the option in the SCSISelect Configuration menu. This is the termination model:

Host adapter location SCSI devices Host Adapter SCSI

Installed at end of bus only 8-bit, or

Installed at end of bus both 8-bit and 16-bit

Not at end of bus* only 16-bit

Not at end of bus* both 8-bit and 16-bit

*In this system, the host adapter on the system board is always at one end of the bus.

Micron NetFRAME LV2000 Server System User’s Guide

Initiate Sync Negotiation—when enabled (set to Yes), the host adapter initiates
synchronous negotiation with the SCSI device; when No, the adapter does not
initiate synchronous negotiation. Normally you should leave this set to Yes,
because the SCSI adapter and its attached devices can transfer data faster in
synchronous mode than in asynchronous. If a device does not support
synchronous negotiation, the adapter will automatically transfer data
asynchronously. If the device initiates synchronous negotiation, the host
adapter always responds accordingly.

Maximum Sync Transfer Rate—the setting determines the maximum
synchronous data transfer rate that the adapter will negotiate with the device.
If you have disabled (set to No) the Initiate Sync Negotiation option, the
maximum sync rate you select is the rate at which the adapter accepts data
from the device; there is no negotiation.

Enable Disconnection—when set to Yes, the adapter allows a SCSI device to
temporarily disconnect from the bus, and the adapter can continue to do other
bus operations. When no, the adapter does not allow a SCSI device to
disconnect.

• Leave this set to Yes if there are two or more SCSI devices on the
bus

• Change to No if there is only one SCSI device connected to the
bus (besides the adapter).

Initiate Wide Negotiation—when set to Yes, the adapter initiates wide
negotiation with each 16-bit SCSI device. You can leave this set to Yes even if
there are 8-bit devices connected; the adapter will not attempt wide negotiation
with 8-bit devices.

Send Start Unit Command—this option reduces the load on the system power
supply by allowing the host adapter to power-up SCSI devices one at a time at
boot time.

• Yes is required for SCSI hard drives; the adapter sends the Start
Unit Command to each SCSI device individually to power-up.

• When set to No, all SCSI devices power up at the same time. If a
device has been jumpered to wait for a start command, it will
not start.

If you enable the command for more than one device, the adapter sends the
command first to the boot device specified in the Boot Device Options menu.
After the first device responds, the adapter sends the command to the remaining
SCSI devices, beginning with the lowest SCSI ID.

Do not enable the Send Start Unit option before checking...

Make sure the AIC-7880 BIOS option is enabled (see Advanced

Host Adapter BIOS—The AIC-7880 BIOS must be enabled to allow these
actions:

• Boot from a SCSI hard drive on the bus.

• Enable any of the other options listed on the same menu
(Advanced Configuration Options).

• Boot from a SCSI CD-ROM drive. If any IDE devices are selected
in the boot order, they will be chosen first over the SCSI device.

If the devices on the SCSI bus are controlled by device drivers and thus do not
need a BIOS, you can disable the option. This frees about 16 KB of memory
and shortens the boot time by up to 60 seconds. However, 2 KB of memory
space is still reserved per PCI and Plug and Play specifications.

Support Removable Disks Under BIOS as Fixed Disks (i.e., hard disks)—the
setting controls how removable-media devices are supported by the
AIC-7880 BIOS. The choices are:

to include it. To boot from a hard drive or other device, either disable this
option or make sure there is no bootable CD in the drive.

BIOS Support for Int 13 Extensions—when enabled, the adapter BIOS
supports Int 13h extensions, required for bootable CD-ROMs. The option
displays only if the adapter BIOS is configured to include bootable CD-ROM
support. You can disable the option if the boot device is not a CD-ROM, but it

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.

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

❏ 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.

Solution Checklist

❏ 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.

Solution Checklist

❏ 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.

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

❏ 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.

Solution Checklist

❏ 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.

Possible Cause

❏ Typically, Micron computers are provided with a 1.44MB 3.5"

floppy drive. An attempt may have been made to format a low­density disk in one of the Micron high-density floppy drives.

Solution Checklist

❏ Please refer to the DOS manual for more information about how

to format low-density diskettes in high-density floppy drives.

Problem

The IDE CD-ROM is not being recognized by the system.

Possible Cause

❏ CMOS is configured incorrectly.
❏ The connection to the CD-ROM is improper or loose.

Solution Checklist

❏ Check in the system’s CMOS Setup to ensure that the

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.

4-6 Micron Electronics, Inc.

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.

Solution Checklist

❏ Check that the modem settings are set correctly and not

conflicting with any other devices.

❏ 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.

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.

Solution Checklist

❏ 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.

Micron Electronics, Inc. 4-7

Micron NetFRAME LV2000 Server System User’s Guide

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.

Solution Checklist

❏ 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.

Hard Disk Problems

Problem

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.

Solution Checklist

❏ 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

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

Possible Cause

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

Solution Checklist

❏ 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 NetFRAME LV2000 Server System User’s Guide

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.

Solution Checklist

❏ 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.

close enough so that you can simultaneously talk with the technical
support representative while you work on the system.

3 . Have a medium- to small-sized Phillips-head screwdriver available.

It’s possible you may need to open your system to correct the
problem.

4 .Write down all error information you can remember, including

error messages, software used (with version numbers), and other
relevant information.

We hope Micron Technical Support will be able to solve your problem over
the telephone. However, in extreme cases, your system may need to be returned
to Micron Electronics, Inc. for repair. The next section describes what to do if
this is the case.

Returning Equipment to Micron Electronics

If it is determined that your system needs to be returned to Micron for repair
or replacement, please observe the rules listed below. Failure to follow any of
these rules may result in long delays in repair or the simple return of the
system without repair.

1 . Contact Micron Technical Support at 1-800-877-8856 to obtain

an RMA (Return Material Authorization) number and to obtain
shipping instructions before returning any portion of your
system.

2 . Make sure all printed-circuit boards or static-sensitive peripherals

are completely enclosed in anti-static bags or foam.

3 . Print the RMA number in large, legible numbers in black ink on

the outside of the shipping boxes.

4 . Enclose a note describing the problem as well as the name of the

technical support representative who authorized the return.

Micron also highly recommends that you follow these additional steps for
your protection:

1 . Make a complete backup of your hard drive(s) before returning

the system.

2 . Use the original packing material that came with your system.
