Preface
Introduction
This guide describes how to configure an au-Series DIGITAL Personal
Workstation running the DIGITAL UNIX or Windows NT operating system to
function as a:
• DIGITAL UNIX only system
• Microsoft Windows NT only system
• Dual-boot system
NOTE: DIGITAL UNIX system users can migrate to Windows NT.
Your au-Series system is 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.

Intended Audience
If you are interested in how to configure a DIGITAL Personal Workstation auSeries system with the DIGITAL UNIX or Microsoft Windows NT operating
system, or both, this information is relevant for you.

au-Series Operating System Installation Guide

Operating System Installation
This guide explains how to install your DIGITAL Personal Workstation au-Series
system with either the DIGITAL UNIX or the Windows NT operating system with
the capability of running either.

Before You Begin
The following guidelines will help ensure a smooth operating-system installation:
• Before you install an operating system, make note of your current system’s
hardware locations, controller types, and boot selections.
• Insure that all options installed are supported by BOTH operating systems, in
particular, Graphics Adapters.
• Ensure that you have all the right bits available for your new operating
system, such as the latest firmware revisions, HAL (hardware abstraction
layer) revisions, and UNIX V4.0C or later.

Console-Specific Considerations
The DIGITAL Personal Workstation au-Series includes two different consoles:
SRM, which is compatible with UNIX and VMS device-naming conventions.
Alpha BIOS 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.
_________________________ Caution ___________________________
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.
It is recommended that, if possible, any disks used by the operating system already
installed, be removed or disconnected while installing the second operating system
software.
____________________________________________________________

au-Series Operating System Installation Guide

NOTE: It is necessary to set the correct date/time prior to completing FIS and
prior to loading the DIGITAL UNIX or Windows NT operating system. Check
the system date/time in each operating system, after switching to new operating
system; correct if necessary

Installing the DIGITAL NT Operating System on a
DIGITAL UNIX System
Your system came with the DIGITAL UNIX operating system preloaded. If you
choose to run the UNIX operating system only, your system is ready to go.
Installing the DIGITAL NT Operating System
Special Considerations
If you choose to run the Windows NT operating system, you must install it from
the CD-ROM that came with your system. 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 received an additional drive with your system. However, you
must ensure
(1) that it contains no data or (2) that any data on the additional 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 corrupt
your UNIX disk.
CAUTION: The Disk Manager utility will prompt you to place a “signature”
on your UNIX disk. Default is Yes, which corrupts the UNIX disk. Take care
to answer No each time you use the Disk Manager utility when the UNIX disk
is in the system.

au-Series Operating System Installation Guide

Windows NT V4.0 Operating System Installation Steps
Follow the step by step instructions below to install Windows NT on a system
already loaded with DIGITAL UNIX.
NOTE: After each command, press either [Return] or [Enter], depending upon
what type of keyboard you have.
I. Switch to SRM Console If SRM is already selected, proceed to Step II.
a) Select CMOS SETUP menu item
b) Press F6 key to enter ADVANCED
c) Tab down to CONSOLE SELECTION
d) Select DIGITAL UNIX Console (SRM)_
e) Press F10 key twice
f) Press [Enter].
g) Power Cycle the system
II. Determine what hard drives are used by UNIX:
a) Type date at the SRM prompt and check the SRM console date (and correct if
necessary) before installing UNIX.
Example:
>>>date
>>>date 199805010935.00
>>>May 01, 1998 9:35 AM
b) At the SRM prompt, boot UNIX by typing in boot dev#

or
if the bootdef_dev variable has been set, just boot.
c) After UNIX has booted, log in.
d) From a DECterm window, type df
e) Note the device id that contains the root, usr and var directories.
Also note any other device that is mounted.
Example:
>df

For the following steps, refer to the UNIX Installation Guide (Order Number
AA-QTLGA-TE).
b) Insert the UNIX Installation CD-ROM
c) Check the SRM console date (and correct if necessary) before installing
UNIX.
Example:
>>>date
>>>date 199805010935.00
>>>09:35:00 MAY 1, 1998
d) At the SRM console prompt, determine the id of your CD-ROM.
Example: >>>show device
e) The UNIX installation menu will appear on the screen after the CD has
booted.
NOTE: When selecting the device to install the root, usr and var directories and
primary /secondary swap space, be sure not to select the device which is the NT
system disk or any hard disk that is to be used with NT. Use the list obtained in
Step I and the attached label to assist in identifying the NT drives on the system.
