Getting Started
Introduction
Your DIGITAL Personal Workstation a/au-Series is a high-performance system that uses
the latest microprocessor and core logic technology. The system, housed in a mini-tower
box, can stand alone or function as a client in an office network environment. This chapter
includes an inventory list of the items shipped with your system and describes how to start,
install, restart, and turn off your system. You can also find information here about
preloaded software as well as guidelines for system security. Figure 1–1 shows a typical
DIGITAL Personal Workstation configuration.

ML013566

Check to make sure you received the following components with your system, and note the
items in Appendix F, Equipment Log, for later reference:
Monitor
Video cable
Documentation

System box
Power cords
Keyboard

Mouse
Microphone
Headphone

Your system may include different components from those listed. Consult the shipping list
that came with your system for an accurate listing of parts. Also, you may refer to the
Quick Setup Guide (ER-B30WW-IM) you received for a pictorial representation of the
system.
If you think something is missing, contact your distributor or DIGITAL representative.

1-2

Getting Started

Pre-Startup Checklist
Before you start your system, perform the following checks:

; Review the information supplied with your system.
; Select a well-ventilated site for your system near a grounded power outlet and

away from sources of excessive heat. The site also should be isolated from
electric noise (for example, spikes, sags, and surges) produced by devices such as
air conditioners, large fans, radios, and televisions.

; Save all shipping containers and packing material for repackaging or moving the
system later.

NOTE: Do not install optional hardware or application software until you have started
your system and verified that the base system is working correctly.
.
WARNING: When unpacking and moving system components, be aware that some
components (such as the monitor) may be too heavy for you to safely lift alone. If you
are doubtful about whether you can lift these items alone, please get assistance.

Creating a Comfortable Work Environment
If you exercise poor posture while you work or if your equipment is poorly set up, certain
recent scientific articles suggest that personal injury may result. Other articles suggest that
there is no cause and effect. Because the safety of our users is a great concern to Digital
Equipment Corporation, we strongly urge that you read and follow the precautions
outlined in Figure 1–2 and Table 1–1. In addition, be sure to adjust your work space so
that you are comfortable, and change your position frequently.

1-3

Getting Started

Additional ergonomic information is provided on the CD-ROM that you received with
your system.

DEC00454

Figure 1–2: Recommendations for Posture and Work Habits
WARNING: If you experience pain or discomfort while using your system, rest and
review the instructions for posture and work habits. If the pain or discomfort
continues after resuming work, discontinue use and report the condition to your job
supervisor or physician.
Table 1–1: Recommendations for Posture and Work Habits
Adjust

To allow the following conditions

Chair

1. Feet are flat on the floor.
2. Legs are vertical and form a right angle to the floor.
3. Your thighs are horizontal, and they are not bearing weight. Keep the
backs of your knees away from the seat so you do not compress the area
behind them, which could restrict the blood flow.
4. Your upper body is erect and your lower back is supported with a
backrest.

1-4

Getting Started

Table 1-1: Recommendations for Posture and Work Habits, continued
Adjust

To allow the following conditions

Keyboard and
Mouse

5. Your wrists are straight and do not flex more than 15 degrees. They
are supported and do not rest on sharp edges. If you use a mouse, rest
your hand on the mouse so your wrist is not on the work surface.
Operate the mouse close to your body's centerline.
6. Upper arms are straight down at your sides, and elbows are close to
your sides and support your arm weight. Forearms are at a 70- to 90degree angle.
7. If you use a mouse, rest your hand on the mouse so that your wrist is
not on the work surface. Operate the mouse close to your body's
centerline.

Head

8. Avoid neck strain. Your head should incline downward, but no more
than 15 to 20 degrees.

Monitor

9. No higher than the level of your eyes and at the correct distance for
your vision.
10.Avoid eye fatigue, which can be caused by glare, image quality,
uncomfortable furniture, eye height, and uncorrected vision. If you
cannot focus to read at different distances, you may need special
glasses. Relax your eyes periodically by focusing on distant objects.

Work breaks

Take periodic work breaks. Morning, lunch, and afternoon breaks during
the 8-hour workday meet most recommendations. Take advantage of
work breaks to move around and do other activities.

Lighting

Avoid direct lighting or sunlight on the screen, which causes glare and
reflections. Place lighting behind or to the side of your work area, and
distribute the lighting evenly on your work area.

Noise

Keep background noise at a minimum. Background noise above 65 dBA
is tiring. Sound-absorbing materials (for example, curtains, carpeting,
and acoustic tile) can help reduce background noise.

Temperature

20 – 23 degrees C (68 - 74 degrees F).

Humidity

30% – 70%.

Ventilation

Provide adequate air ventilation to operate the equipment and avoid
fatigue.

Work Space

> 70 cm (28 inches) center to center, preferably between > 152 cm (60
inches).

1-5

Getting Started

Installing Your System
The Quick Setup Guide you received with your system graphically outlines the installation
steps.
CAUTION: To ensure proper cooling, verify that air can flow freely into the system front
and out the rear of the system.
Position your system so that air can flow freely to and from the vents, as Figure 1–3
shows. Do not block any of the vents, especially those on the system rear or bottom front.

Configuring Your System
Introduction
This chapter explains how to:
•

configure your DIGITAL Personal Workstation

•

migrate to Windows NT (au-Series systems only)

•

migrate to a dual-boot environment (au-Series systems only)

See the specific sections that follow for information on configuring an a-Series system
running the Microsoft Windows NT operating system; an au-Series system running the
DIGITAL UNIX operating system; or an au-Series system migrating to Windows NT or to
a dual-boot environment.

Configuring an a-Series System
This section shows you how to configure your a-Series system running the Microsoft
Windows NT Workstation operating system using the AlphaBIOS firmware.
NOTE: The screens shown are examples only. Your system display may vary from the
examples shown.

Using AlphaBIOS Firmware
AlphaBIOS firmware supports the Microsoft Windows NT Workstation operating system.
You can use AlphaBIOS firmware to perform various configuration tasks, such as:
•

Selecting a copy of the Windows NT system to boot.

•

Displaying system configuration information.

•

Setting up the hard disk.

•

Setting the date and time.
3–1

Configuring Your System

•

Enabling and setting the delay for auto start.

•

Setting or changing the AlphaBIOS password.

•

Setting up boot utilities.

Starting AlphaBIOS
When the system is powered on, and the power-on self-tests (POST) successfully
complete, the AlphaBIOS firmware is loaded and started. AlphaBIOS performs several
initialization tasks, including: initialize the keyboard and video devices, test memory, and
detect and initialize disk controllers. After the video device is initialized, subsequent steps
are displayed on the monitor in an initialization window.
When initialization is complete, AlphaBIOS leaves the initialization window and displays
the boot screen.
Booting the System
The system is booted from the boot screen (Figure 3–1). The boot screen lists each of the
different copies of the Windows NT operating system that have been installed on your
system. Choose the operating systems to boot and press [Enter] or enter the AlphaBIOS
Setup program by pressing [F2].

Figure 3–1: AlphaBIOS Boot Screen

3–2

Configuring Your System

AlphaBIOS Setup
Start the AlphaBIOS Setup program by pressing [F2] while the boot screen is displayed.
Figure 3–2 shows the AlphaBIOS Setup screen. Use the setup screen to select the desired
task. Press [Escape] to return to the boot screen.

Figure 3–2: AlphaBIOS Setup Screen

3–3

Configuring Your System

Displaying Your Configuration
AlphaBIOS provides a clear, easy-to-read display of the system configuration. The display
is organized by systemboard, memory, hard disk, PCI, and integrated devices. From the
AlphaBIOS Setup screen, select Display System Configuration and press [Enter]. From
the Display System Configuration screen, use the arrow keys to select the configuration
category you wish to view. Figure 3–3 shows the Systemboard Configuration category.

Figure 3–3: Display System Configuration Screen
Memory Configuration
The memory configuration display shows bank size, the starting address of each bank, and
the capacity of the DIMMs in the bank.
PCI Configuration
The PCI configuration screen displays both the embedded and the slot-mounted PCI
devices. The device names and types, along with their respective revision levels, are
displayed.

3–4

Configuring Your System

SCSI Configuration
If you ordered a base system configuration, you have the option of ordering either an
Adaptec 2950 ultrawide SCSI adapter or a Qlogic 1040B ultrawide adapter
(SN-KZPBA-CA). If you ordered a packaged system, your system came with an
embedded Qlogic adapter.
Integrated Peripherals
The integrated peripherals screen display shows the addresses and IRQs of the serial and
parallel ports.
Setting Up the Hard Disks
AlphaBIOS makes it easy to format and partition hard disks on the system. Typically, you
partition and format drive 0. Using the Windows NT Disk Administrator, you can quickly
partition and format the other drives. Select Hard Disk Setup from the AlphaBIOS Setup
screen. Figure 3–4 shows the Hard Disk Setup screen.

Figure 3–4: Hard Disk Setup Screen
Press [F7] to perform an express disk setup. The express setup command partitions and
formats the selected disk in the recommended manner (6 MB FAT system partition).
CMOS Setup Tasks
Use the CMOS setup program shown in Figure 3–5 to configure system parameters such as
the date and time, floppy drive types and capacities, keyboard country and style, and auto
start enabling and delay. There also is an advanced CMOS setup mode used to control PCI
parity checking, memory testing, and AlphaBIOS password.
To enter CMOS Setup, select CMOS Setup from the AlphaBIOS Setup screen. Use [Tab]
to move among the fields.

3–5

Configuring Your System

Figure 3–5: CMOS Setup Screen
Date and Time
When setting the time, use the 24-hour format; for example, 10:00 P.M. should be
expressed as 22:00:00.

3–6

Configuring Your System

Floppy Drive
AlphaBIOS supports the following drive types:
•

3.5-inch, 1.44-MB (shipped with system)

•

5.25-inch, 1.2-MB

•

3.5-inch, 2.88-MB

Keyboard
The keyboard setting allows the use of nearly any language keyboard available. To ensure
correct character mappings, make sure that the language of your keyboard, Microsoft
Windows NT Workstation, and the keyboard-language selection in CMOS setup all match.
Auto Start and Auto Start Count
The Auto Start setting determines whether the primary operating system is automatically
started after the system is reset or power-cycled. The Auto Start Count setting is the
amount of time the boot screen is displayed before the default system is automatically
started. This delay gives you the opportunity, after resetting or power-cycling the system,
to select another operating system to start or to enter AlphaBIOS setup.
CMOS Setup Options
• Color. Pressing [F3] repeatedly cycles through the available AlphaBIOS color
schemes.
•

Advanced. Pressing [F6] displays the Advanced CMOS Setup screen.

•

Defaults. Pressing [F7] restores the default standard CMOS setup values without
affecting the advanced CMOS setup values.

•

Discard Changes. Pressing [Escape] restores the settings that were in effect when
you started CMOS setup. This option also discards changes made in advanced CMOS
setup.

•

Save Changes. Pressing [F10] saves changes made in both the standard and advanced
modes of CMOS setup.

3–7

Configuring Your System

Advanced CMOS Setup
Enter the advanced CMOS setup screen shown in Figure 3–6 by pressing [F6] in the
CMOS Setup screen.

Figure 3–6: Advanced CMOS Setup Screen
PCI Parity Checking
This setting controls PCI parity checking at the PCI bridge chip. Parity checking is
performed if enabled and ignored if disabled. The default is disabled. Certain PCI
adapters have been known to generate bad parity on the PCI under certain loading
conditions, which results in system errors. Ensure that your specific PCI configuration
will operate correctly prior to turning on parity checking.
Extended Memory Test
Extended memory test can be enabled or disabled. When enabled, the memory test writes
and then reads several patterns of data to main memory. This testing verifies the integrity
of the memory but causes a slightly longer boot time.

3–8

Configuring Your System

Password Setup
To help maintain system security, AlphaBIOS provides two levels of password protection:
system setup and system startup. When system setup protection is enabled, you need a
password to enter the AlphaBIOS setup program. When system startup protection is
enabled, you must enter a password before system initialization will take place. Startup
password protection provides more comprehensive protection than setup password
protection because the system cannot be used until you enter the correct password.
NOTE: To change the password, simply set up your password again.
Advanced CMOS Setup Options
• Discard changes. Pressing [Escape] restores the settings in effect when you entered
advanced CMOS setup. This does not discard changes made to standard CMOS setup.
•

Save changes. Pressing [F10] saves changes you have made in advanced CMOS
setup. When exiting CMOS setup, you also must save your changes at the CMOS
setup screen for the changes to be stored permanently.

Utilities
Two utilities, operating system selection and run a maintenance program, are available
from the utilities menu.

3–9

Configuring Your System

OS Selection Setup
Each operating system selection is a set of information that describes the disk and partition
containing OSLOADER.EXE, as Figure 3–7 shows.

Figure 3–7: Operating System Selection
Running a Maintenance Program
A maintenance program, such as a RAID configuration utility, is run directly from the
AlphaBIOS utility menu.
To run a maintenance program, follow this procedure:
1.

Start AlphaBIOS setup, select Utilities, select Run Maintenance Program from the
submenu, and press [Enter].

In the Current Partition field, select the hard-disk partition, floppy disk, or CD drive from
which to run the program. Type the program name into the Program Name field.

Table 3–9: SRM Environment Variables (continued)
Variable

Description

ewa0_mode

Selects which Ethernet port to use: AUI (ThinWire); twistedpair; Full Duplex, twisted-pair; BNC; Fast (for Fast Ethernet
controllers); or FastFD (for Fast Ethernet controllers that support
Full Duplex). AUI is the default. (Auto-sensing is not
supported.)

ewa0_protocols

Determines the Ethernet protocol, which can be either MOP or
BOOTP. MOP is the default.

kbd_hardware_type

Selects the type of keyboard on your system. Possible values are
LK411 or PCXAL. PCXAL is the default.

language

The language environment variable associates language n to the
system (where n is the number of the language shown below).
You can have the system prompt you for the language using the
following command: >>>set language 0 and then
>>>init. Select the desired language. Type >>>init
again, then power cycle the system.

os_type

Identifies the operating system being used on the system. Values
of UNIX cause the SRM console to load.

pci_parity

This variable controls PCI parity checking at the PCI bridge chip.
Parity checking is performed if on, disabled if off, and dependent
on the SCSI controller revision if sniff. Default is off.
Certain PCI adapters have been known to generate bad parity on
the PCI under certain loading conditions, which results in system
errors.
Ensure that your specific PCI configuration will operate correctly
prior to turning on parity checking.

Adding ISA Bus Devices
ISA Configuration Utility
ISA devices cannot be probed for configuration information by the DIGITAL UNIX
operating system. Therefore, you must enter ISA option information manually using the
ISA configuration utility. Run this utility before installing a new ISA option module on a
DIGITAL Personal Workstation au-Series system running the DIGITAL UNIX operating
system.
Two methods are available to perform ISA configuration tasks: a forms-based interface
(ICONFIG) and a command line interface (ISACFG).

3–19

Configuring Your System

ICONFIG Utility
The ICONFIG utility is a subset of the ISACFG utility. Only one type of each field (or
option) can be set (for example, one IRQ or one I/O address) in ICONFIG. Future
versions will include more functionality.

Migrating to Windows NT or to a Dual-Boot Environment
This section describes how to migrate your au-Series system from the DIGITAL UNIX
operating system to Microsoft Windows NT or to a dual-boot system.
Your au-Series system was preloaded with the DIGITAL UNIX operating system and
includes the latest firmware. Consult the DIGITAL Web site for firmware updates:
http://www.workstation.digital.com/firmware.html.

Before You Begin
Observe the following guidelines to help ensure a smooth transition to Windows NT or to
a dual-boot environment:

3–24

•

Note your current system’s hardware locations, controller types, and boot selections.

•

Record how the console reports controllers and devices. Refer to the section earlier in
this chapter on using SRM firmware for help in using console firmware to obtain this
information.

•

Verify that the controllers and devices installed in your system work properly under
both operating systems. Options that shipped with your au-Series packaged system
should work under both DIGITAL UNIX and Windows NT. However, any options
that you may have added should be verified for compatibility. Consult the System
Options Catalog (SOC) at http://www.digital.com/info/SOC for more information.

Configuring Your System

•

Carefully record any important environment variables used by DIGITAL UNIX for
safekeeping and back up any important data on your system’s hard drives.

•

Verify that you are using the latest firmware before installing another operating
system. Even though your system may work well now, it may require a firmware
upgrade to run in a different operating system or in a dual-boot environment.

•

Make sure that you have all drivers and support diskettes necessary to install Windows
NT as well as any installed options.

Console-Specific Considerations
The DIGITAL Personal Workstation au-Series includes two different consoles: SRM,
which is compatible with UNIX and VMS device-naming conventions. AlphaBIOS
firmware has been tailored for compatibility with the Windows NT operating system
device-naming conventions. These two consoles use different methods for recording user
preferences, boot selections, and time of day.
Because of the different naming conventions that DIGITAL UNIX and Windows NT use,
it is crucial that you record the disk configurations as both consoles view them prior to
changing settings or the hardware itself. See the specific instructions later in this guide.
Using the Windows NT Operating System
Special Considerations
If you choose to run the Windows NT operating system, you must install it from
CD-ROM. Before beginning the installation, please read through the following
considerations.
Hardware Requirements
Windows NT requires a separate hard disk drive. UNIX and NT cannot reside on the same
drive. You must ensure that your target drive (1) contains no data or (2) that any data on
the drive is backed up before you attempt to have two operating systems reside on your
workstation.
Precautionary Measures
CAUTION: Installing and running two operating systems on one machine carries risks.
To minimize these risks, first ensure that you have backups of all your files.
If you do not plan to keep the DIGITAL UNIX operating system on your machine, you
may want to remove UNIX and the data hard drive for safekeeping.
The Windows NT Disk Manager utility does not recognize the format of a UNIX disk.
Therefore, take care when recording the SCSI ID of your UNIX disk and disk numbers so
that you do not inadvertently allow the Disk Manager to destroy data on your UNIX disk.

3–25

Configuring Your System

CAUTION: The Windows NT Disk Manager utility will prompt you to place a
“signature” on your UNIX disk. Default is Yes, which does not preserve the UNIX disk.
Take care to answer No each time you use the Disk Manager utility when the UNIX disk is
in the system.
Early versions of the console firmware did not preserve certain environment variables
when switching between operating systems. If you choose to configure your DIGITAL
Personal Workstation au-Series system as a dual-boot system, you should verify that the
DIGITAL UNIX SRM console firmware is version 6.4-278 or later. Using an earlier
version will cause the loss of boot paths when you switch between operating systems.
Use the following command from SRM to determine which version of the firmware is on
your system:
>>>show version
You can download current versions of the firmware from the DIGITAL external Web site
at http://www.workstation.digital.com/firmware.html.

Your DIGITAL Personal Workstation a/au-Series system has five expansion slots,
including:
•

One half-size PCI slot (slot 1)

•

One half-size PCI/ISA combination slot (slot 2)

•

Two full-size PCI/ISA combination slots (slots 3 and 4)

One full-size PCI slot (slot 5)

•

Refer to your option module documentation for instructions on configuring a PCI
or an ISA option module.

Adding Mass Storage Devices
Overview
This section covers configuration guidelines, general drive-installation information, and
cable layouts. The a/au-Series DIGITAL Personal Workstation supports a maximum of
six mass storage devices internally:
•

The top device bay contains a factory-installed 3.5-inch floppy diskette drive.

•

The second device bay contains a factory-installed CD-ROM drive and room for two
additional 5.25-inch half-height removable devices; 3.5-inch devices are supported
with adapters.

•

The internal device bay is not accessible from the front of the workstation and
contains a factory-installed, low-profile (1-inch high), 3.5-inch hard disk drive. This
device bay also has room to install a second low-profile (1-inch high), 3.5-inch hard
disk drive.

Removing Front Bezel
To install a device into the front bays, you must first remove the workstation's front bezel.
Refer to Figure 4–4, and follow the steps outlined:
1.

Turn off your workstation and monitor.

Disconnect all external devices, AC power, and monitor power.

Remove the outside cover, according to the steps outlined earlier in the section,
Removing the System Cover.

From the top of the workstation, looking down toward the bottom of the front of the
chassis, view the two tabs from the front bezel that hold the bezel in place and secure
it to the chassis. Find both tabs (one on the left and one on the right).

4–7

Installing System Options

Push both tabs toward the center of the workstation to release the top of the bezel.

Gently pull the top of the bezel approximately 1 inch away from the top of the chassis.

Gently, but firmly, pull up on the bezel to unhook the bottom bezel mounts.

At this time, you may remove the bezel door.

Installing System Options

Configuration Guidelines for SCSI
System configurations ordered with a SCSI host adapter ship with a Qlogic 1040UW Ultra
Wide SCSI PCI host adapter. DIGITAL Personal Workstations support up to four drives
attached to the adapter’s wide internal bus. Narrow devices can be attached to that bus
when a 68- to 50-pin adapter is used.
NOTE: At this time, no external devices are supported on the same adapter used for
internal devices.
Add a SCSI adapter if you need to attach external SCSI devices.
SCSI can connect computers to peripheral devices, such as CD-ROM drives, tape drives,
or hard drives. Ultra Wide SCSI allows up to 15 SCSI devices to be connected to a single
port using a daisy chain. (A daisy chain is a series of connections in which the first device
is connected to the computer, the second device is connected to the first, and so forth.)
Each SCSI device must have a unique SCSI ID.
Bus Length
For Ultra SCSI, the total length of all the cables cannot exceed 1.5 meters (5 feet). The
first SCSI card handles only the internal drives. Use another card for external devices.

4–9

Installing System Options

Termination
A SCSI bus must be a continuous, linear electrical connection, with termination at each
end. SCSI stubs off the main line must not exceed 10 cm. The adapter provides
autosensing software-controlled active termination.
There are three connectors on the SCSI adapter:
•

68-pin, high-density external SCSI-2 connector

•

68-pin, high density internal SCSI-2 connector

•

50-pin internal ribbon connector

You can use one or two of the connectors on the card, although it is difficult to meet SCSI
bus length restrictions when using more than one connector. Using three violates the SCSI
stub length rules.
The first SCSI adapter card can be used only for internal devices because of bus length
restrictions. Only the internal 68-pin connector is used. Termination is provided at one
end of the bus by an active terminator built onto the internal cable, and the other end of the
bus by termination on the adapter card itself.
Additional SCSI adapter cards can be added to connect external devices. Only the external
68-pin connector is used. The adapter card terminates one end of the bus, and you must
supply active termination at the end of the external bus. You must not exceed the SCSI
bus length restriction of 1.5 meters for UltraSCSI transfer rates.

)

Refer to the SCSI controller documentation for more information.

Installing Storage Devices
This section describes how to install drives in the front-accessible bays and the internal
bays.
NOTE: Be sure to read the instructions that come with your new equipment as well as the
appropriate instructions in this section.

Front-Accessible Bays
Normally, the system arrives with a floppy diskette drive in the top, front-accessible bay
and a CD-ROM drive in the bottom bay. There are two half-height 5.25-inch bays
available for additional drives. Perform the following steps to add a drive in a frontaccessible bay:

4–10

Remove the system cover. (Refer to the section, Removing the System Cover, earlier
in this chapter.)

Remove the front bezel assembly. (Refer to the section, Removing the Front Bezel,
earlier in this chapter.)

Installing System Options

Remove the appropriate filler panel from the front bezel (for drives requiring front
access).

Refer to the drive's documentation and set the drive jumpers (drive 0 for ATAPI
CD-ROM, SCSI ID for SCSI drives).

If you are installing a 3.5-inch drive, attach the expansion brackets to the sides of the
drive, as Figure 4–5 shows.

Installing Main Logic Board Options
Introduction
This chapter covers the following topics related to installing main logic board (MLB)
options on your DIGITAL Personal Workstation a/au-Series system:
•

Installing additional system memory

•

Replacing the battery

Adding Memory
The procedure for adding DIMMs to the DIGITAL Personal Workstation a/au-Series
system is outlined below.
There are three memory banks (J1/J2, J3/J4, and J5/J6) in the system; each bank consists
of two DIMMs. Two DIMMs are required because the memory bus width is 144-bits (128
bits of data and 16 bits of ECC). Each DIMM in a bank supplies 72 bits of the 144-bit bus
width. Both DIMMs in a bank must be identical, and both must be populated.
To add memory modules (DIMMs), refer to Figure 5–1 as you perform the following
steps:

Install the DIMM straight into the socket. Position the DIMM so that both the
retaining clips at the socket ends engage. Pay close attention to the keying on the
DIMM and the socket.

Repeat step 1 for the remaining modules.

Replacing Battery
The battery supplies power to the realtime clock while the system is off. If necessary,
replace the lithium battery with a DIGITAL (P/N 12-41474-05), Toshiba (P/N CR2032), or
equivalent 3-Volt DC lithium battery. After replacing the battery, you must verify the
system configuration and setup data.
WARNING: If the battery is incorrectly replaced, there is danger of explosion.
Replace the battery only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to manufacturer's instructions. Be
certain to follow any state or local statutes for proper battery disposal.
CAUTION: Take care not to bend the spring that holds down the battery. A bent spring
could result in poor battery contact and intermittent system problems.
To replace the battery, refer to Figure 5–2 and perform the following steps:
1.

Gently press down on the battery and push it out sideways, as Figure 5–2 shows.

Insert the new battery, positive side (+) up, into the holder.

Troubleshooting
Introduction
This chapter describes initial and system troubleshooting for your DIGITAL Personal
Workstation a/au-Series system.

)

Refer to the documentation supplied with additional options if you are
experiencing problems with specific options that you have installed.

Tips
Use these troubleshooting tips should your computer ever fail to operate correctly.
•

Keep it simple; only troubleshoot one problem at a time. Also, only make one change
at a time. For example, if your SCSI hard disk drive fails to boot, do not try all the
suggested actions at once. Instead, start with one suggestion such as checking the
cables. After securing the cables, try booting your computer. If it does not work, try
another suggestion.

•

Look for abnormal computer, keyboard, and monitor LED indications. For example,
make sure the power on LED lights when you turn on your computer and the drive
access indicators light when using either the diskette drive or hard disk drive.

•

If you installed external devices, make sure all cables are correctly and securely
connected to the appropriate devices and that the devices are installed correctly.

•

If you installed devices inside the computer, make sure nothing was bumped or jarred
loose, and that all cable connections are securely in place.

•

Make sure all device drivers are installed correctly.

6–1

Troubleshooting

•

Press the Reset button. Try rebooting your system.

•

Pay close attention to any error message that appears on your screen.
If the error message is computer related, refer the section on Error Messages later in
this chapter for recommended actions.
If the error message is Windows related, refer to any online help and the appropriate
Windows documentation supplied with your computer.

•

Listen carefully for computer errors in the form of beeps. Record the number of beeps
and their patterns then check the Beep Code descriptions later in the chapter for
recommended actions.

•

README files might be factory installed, on the CD-ROM disk, or as printed
material. This README information can help you setup, configure, and operate your
computer.

NOTE: If DIGITAL support tells you to return a failed component, pack it in its original
container and then return it to DIGITAL or your DIGITAL Authorized Distributor as
instructed.
•

Check that the power indicator is on and that the fan is running.

•

Check the power indicator on the monitor. Also, check the monitor, keyboard, and
mouse cables to ensure that they are connected and seated properly.

•

Make sure that all cables and connections are secure.

•

Contact DIGITAL Services or your service provider for software- or hardware-related
problems.

Equipment Log
For your convenience, Appendix F, Equipment Log, includes a form on which you can
record all model numbers and serial numbers of your hardware components (system unit,
monitor, keyboard, and mouse) and system hardware configuration information (CPU,

Troubleshooting

Error Beep Codes
Table 6–5 shows error beep codes you may encounter while using the DIGITAL Personal
Workstation a/au-Series system. For example, if the POST (power-on self-test) code
could not find any good memory, you would hear a 1-3-3 beep code (one beep, a pause, a
burst of three beeps, a pause, and another burst of three beeps).
Table 6–5: Error Beep Codes
Beep
Code

Meaning

1-1-4

(1) The POST code could not read the POST or flashROM
headers, or (2) there was a checksum failure.¹

1-2-1

(1) The POST code detected a TOY (time-of-year clock) failure,
or (2) the TOY interrupt did not occur.

1-2-4

The POST code detected a hard failure.

1-3-3

The POST code could not find at least 2 MB of good memory.

3-2-1

The POST code was unable to read the header of the flashROM,
or the flashROM checksum failed. Therefore, the POST code
attempted to boot from the floppy diskette. The attempt failed
because there was no boot block on the floppy diskette.¹

3-2-3

The POST code was directed to load the floppy diskette, but there
was no boot block on the floppy diskette.

3-2-4

The POST code detected a failure with the keyboard or mouse
controller.

3-3-1

The POST code detected a hard failure. The LEDs may provide
more diagnostic information.

¹ These failures may be recoverable if you have prepared an ERD (emergency repair disk).

LEDs
Your a/au-Series system contains eight diagnostic LEDs (visible at the top of the MLB
with the system cover removed) as well as one power-on LED. During execution of the
POST (power-on self-test), before a console display device is available, some errors are
reported by the LEDs. The LEDs are written with CDh once the system is fully functional.
Depending upon your operating system, LEDs may remain lighted even though the system
is functioning properly. If, however, your system is experiencing problems and any of the
LEDs on your system stay lighted, contact your DIGITAL service representative.

Cleaning the System Unit
Clean the outside of the system periodically with a soft cloth lightly moistened with a mild
detergent solution. Do not use solvents or abrasive cleaners.

Cleaning the Monitor
If the monitor screen gets dirty, clean it with a sponge or chamois cloth lightly dampened
with a mild detergent solution. Do not use solvents or abrasive cleaners.
WARNING: If you use a prepackaged screen cleaner, ensure that it is nonflammable.
To prevent cleaner from seeping into the system case, never spray the cleaner directly
on the screen. Instead, apply the cleaner to a clean cloth, and then wipe the screen.

A–1

System Care

Cleaning the System Mouse
If the mouse does not move smoothly or if the pointer jumps across the screen when you
are using the mouse, the ball inside the mouse may need cleaning. To clean the ball,
perform the following steps as Figure A–1 shows:
1.

Turn the mouse over and remove the plate on the bottom.

Remove the locking ring and rubber ball

Clean the ball and rollers with a cotton swab that has been lightly dampened with a
mild detergent. Rinse the ball and rollers with a dampened cotton swab.

Replace the ball and plate

NOTE: Consistent use of a high-quality mouse pad will decrease debris build-up in the
mouse ball.

A–2

System Care

Cleaning the System Keyboard
From time to time, the keyboard keys might get dirty with use. Wipe the keys with a clean
cloth that has been lightly dampened with a mild detergent solution.

Moving the System
Perform the following steps before shipping or moving the system:
1.

Back up all files stored on the hard disk drive.

Turn off the external peripherals, the system, and the monitor.

Disconnect the power cord from the wall outlet and from the back of the system unit.

Disconnect the monitor, keyboard, mouse, and any other cables from the back of the
system unit.

Package the system as the next section, Packing Your System, describes.

Packing the System
If you are moving the system a short distance (for example, from one room to another in
the same building), you may not wish to pack it. If you are shipping the system or moving
it by vehicle, though, pack it to avoid damage.
Pack the system in the original packing material and containers. If you did not save the
boxes and packing material, use a sturdy carton and cushion the computer well to avoid
damage.

Installing the System at a New Location
After moving the system to a new location, follow the installation instructions on the
installation information to unpack and install it.

Updating System Firmware
Introduction
This appendix explains how to use the firmware update utility to install firmware
upgrades.
NOTE: The user is responsible for performing system firmware upgrades. Consult your
upgrade documentation for more information.
Consult the appropriate section for system information, depending upon whether you have
an a-Series system running the Windows NT operating system or an au-Series system
running the DIGITAL UNIX operating system.

a-Series System Firmware
The DIGITAL Personal Workstation a-Series system contains 1 MB of flashROM for the
console firmware. The flashROM contains the AlphaBIOS firmware.

Update Utility
Use the update utility to update your AlphaBIOS. The update utility contains two images:
the update utility itself and the AlphaBIOS image.

Using the Flash Update Utility from AlphaBIOS
You may update the firmware by either using the supplied CD or by copying the firmware
from the Internet onto a floppy diskette.

Updating Firmware from AlphaBIOS
To update the firmware from AlphaBIOS using the firmware CD or floppy diskette, follow
these steps:
1.

Shut down the Windows NT operating system and restart the system.
D–1

Updating System Firmware

Insert the Firmware Update CD-ROM or a floppy diskette (prepared as the next
section describes) into the appropriate drive.

From the AlphaBIOS boot screen, press [F2] to enter AlphaBIOS setup.

From the AlphaBIOS setup screen, select Upgrade AlphaBIOS.

HINT: AlphaBIOS verifies the system image and displays the old and new firmware
versions.
5.

Follow the screen prompts to complete the update.

Preparing a Firmware Floppy Diskette
Copy the firmware over the Internet from the ftp.digital.com/pub/Digital/Alpha/firmware
area and follow these steps:
1.

Format a blank floppy diskette (FAT).

Copy the appropriate file to Drive a:.

au-Series System Firmware
The DIGITAL Personal Workstation au-Series system contains 1 MB of flashROM for the
console firmware. The flashROM contains the SRM console firmware (for the DIGITAL
UNIX operating system).

Update Utility
Use the update utility to update your SRM firmware. The update utility contains two
images: the update utility itself and the SRM image.

D–2

Updating System Firmware

Using the Flash Update Utility from the SRM Console
To update the firmware from the SRM console, do the following:

Installing an Operating System
Introduction
This information provides what you need to begin an operating system installation. Once
you have started an installation, follow the on-screen instructions and refer to the
appropriate operating system documentation.
Refer to Table E–1 for instructions on installing the Microsoft Windows NT operating
system on a properly partitioned and formatted disk; see Table E–2 for instructions on
setting up partitions for an NT installation. Refer to Table E–3 for instructions on
installing the DIGITAL UNIX operating system.
CAUTION: If you boot from a DIGITAL UNIX disk and also occasionally boot Microsoft
Windows NT from another disk, use caution when you run the Windows NT Disk
Administrator. When the Disk Administrator detects additional disks, it updates the
system configuration. The Disk Administrator prompts you for permission to write a
signature to the additional disks. Writing the signature to a DIGITAL UNIX disk destroys
the boot block on that disk and makes the operating system on that disk no longer
bootable. Select NO when you are asked if you want to write a signature to your
DIGITAL UNIX disk.

E–1

Installing an Operating System

Starting a Windows NT Installation
Digital partitions and formats disk 0 on the first SCSI controller in non-RAID Windows
NT systems. The partitions are set up as follows:
•

Partition 1 (typically, the "C" drive) is the size of the disk less 6 MB and formatted
FAT. Normally, you select "convert to NTFS" during the Windows NT installation.

•

Partition 2 (typically, the "D" drive) is 6 MB, formatted FAT, and identified as the
system partition.

Refer to Table E–1 for the steps to start installing the Microsoft Windows NT operating
system on a properly partitioned and formatted disk.
