GETTING READY TO SET UP YOUR SYSTEM
------------------------------------

System Configuration Overview

There are several steps that must be performed in the correct 
order to prepare your system for installation of Microsoft Windows 
NT. The following procedure provides an overview of the 
configuration process. You can click on the links in each step to 
get more details about that step. As you will read in each of 
these sections, some of the steps may not apply to you; therefore, 
it is important that you read each section and any procedure in it 
before performing the procedures.

To set up your system: 

1.  Gather the information and materials you will need.
 
2.  Read the System Issues section of this document to learn about 
    any special considerations for your system model. 

3.  Set the operating system type to Windows NT if you are moving 
    to Windows NT from Digital UNIX or OpenVMS. 

4.  Update your system firmware if necessary. 

5.  Set the default system configuration if your system has never 
    been configured, or if you are moving to Windows NT from Digital 
    UNIX or OpenVMS. 

6.  Run the EISA configuration Utility (ECU) if your system has an 
    EISA bus and you have added, removed, or moved any EISA cards in 
    your system. The ECU must be also be run if you are moving to 
    Windows NT from Digital UNIX or OpenVMS. 

7.  Partition and format your hard disk for use with Windows NT if 
    this has not already been done. 

8.  Install a fresh copy of Windows NT, or upgrade from an earlier 
    version. 

9.  Install additional video support if your system has a TGA 
    video adapter.



Preparing to Set Up Your System

  example, video drivers, SCSI drivers, and network adapter drivers.



Obtaining Firmware Updates

Firmware updates can be obtained in several ways:

o From the Internet via the WWW or FTP. These always have the very 
  latest released firmware.

o From Digital Customer Service, by calling 1-800-354-9000 in the 
  United States, and asking for the latest firmware diskette for 
  your system model.

o The latest Digital Alpha System Firmware Console CD-ROM. This has 
  the latest firmware as of the CD-ROM date.

If you are unsure about your particular upgrade requirements, call 
the Digital Equipment Corporation Technical Support line at 1-800-
354-9000 for further assistance in the United States. For 
locations outside the United States, contact your local authorized 
Digital partner for assistance.

Note: Each system line has its own independent firmware numbering 
scheme. Even though two different system lines might have firmware 
with the same revision number, they are not the same. For example, 
firmware revision 4.43 from the AlphaServer 2100A 5/xxx line will 
not work on systems from the AlphaServer 2100A 4/xxx line. When 
you update your systems firmware, make sure to obtain the 
firmware for your specific system line.

To obtain firmware via the Internet using FTP:

This procedure assumes you are using a command-line FTP utility. 

1.  Start an FTP session. 

2.  Type open gatekeeper.dec.com and press Enter. 

3.  At the User prompt, type anonymous and press Enter. 

4.  At the Password prompt, type your Internet e-mail name, for 
    example, joe@company.com. If you do not have an Internet e-mail 
    name, just type your first and last name. 

5.  At the FTP prompt, type cd /private/fwaxp and press Enter. 

6.  Type get readme.txt and press Enter. This file contains a 
    complete list of the firmware and ECU revisions needed to run 
    Microsoft Windows NT on Digital Alpha systems. This document also 
    provides specific instructions on what files to download to obtain 
    the latest firmware and ECU configuration files for your system. 

7.  Once you have determined which files you need, return to the 
    FTP session, type bin, and press Enter. This command makes it 
    possible to receive binary files. 

8.  Using the following format, type the command to receive a 
    file, where filename is the file you want to receive: get 
    filename. Then press Enter. The file is transferred to the 
    directory from which you started the FTP session. Repeat this 
    process for each file you want to receive. 

9.  When you are done receiving the file(s) you need, type bye and 
    press Enter. This will end the FTP session.

To obtain firmware via the Internet using a WWW browser: 

1.  Connect to URL http://www.windowsnt.digital.com. 

2.  Go to the Drivers and Firmware section.

To obtain the Digital Alpha System Firmware Console CD-ROM:
You can obtain Alpha system firmware updates on CD-ROM by calling 
1-800-DIGITAL in the United States or your local authorized 
Digital partner, and ordering one of two part numbers.
To obtain just the latest firmware CD-ROM, order part number QZ-
003AA-E8.

To obtain a 1 year subscription of quarterly CD-ROM updates, 
order part number QY-003AA-A8.



General System Issues

The following system issues detail items to be aware of when 
configuring your system. Depending on the features of your system 
model, some of the items listed might not apply to you. If you 
have an AlphaServer 2100A system, also see the AlphaServer 2100A 
Specific System Issues section.

Digital TGA Graphics Adapter

If your system has a TGA graphics adapter installed, Windows NT 
Setup automatically installs the 2D graphics driver. The OpenGL 3D 
graphics accelerator libraries, however, are not installed as part 
of Windows NT setup. If you want full support for OpenGL 3D 
graphics, you must install the TGA driver after Microsoft Windows 
NT setup is completed. For more information, see Installing OpenGL 
3D Support.

RAID Controller

If you have the Digital SWXCR RAID controller installed, you must 
use version 3.11 or greater of the RAID Configuration utility with 
Windows NT.

Disks connected to the StorageWorks RAID Array 200 Subsystem 
(the RAID Array Subsystem includes the SWXCR EISA backplane RAID 
controller) must be spun up before they can be accessed. While 
running the ECU, verify that the controller is set to spin up four 
disks every 6 seconds. This is the default setting if the default 
configuration files for the SWXCR controller are being used.

Make sure to reset the computer after changing the RAID 
configuration. This reset is required to make your changes take 
effect.

There is an anomaly in Windows NT that can cause the system to 
crash if the SWXCR utilities and the Windows NT Disk Administrator 
program are both run at the same time. Do not run the SWXCR 
utilities and Disk Administrator utility concurrently.

ARCINST Utility Fails with Hard Disks Greater Than 2 Gigabytes
The version of Arcinst included with Windows NT 3.51 fails with an 
error code if you try to manipulate physical partitions or logical 
RAID units with a size value greater than 2024 megabytes. The 
solution to this problem is to either:

Obtain the latest Arcinst utility from Digitals Windows NT WWW 
site at http://www.windowsnt.digital.com. This version does not 
have the size limitation.

Work with partition and RAID logical unit sizes of less than 2024 
megabytes.

EISA Bus Configuration

When updating the EISA configuration, make sure to use the 
Microsoft Windows NT ECU diskette. Using the ECU diskette for 
OpenVMS or Digital UNIX may result in an inoperable system. If you 
make a backup of the ECU diskette, ensure that the volume label is 
SYSTEMCFG.

The ECU does not automatically configure ISA cards. For example, 
if you add an Adaptec AHA154x to the bus, you will need to choose 
the Add a Board option within the ECU and select !ISA0000.CFG for 
the ISA slot. You can then manually configure the AHA154x, which 
will force the ECU to resolve ISA-EISA resource conflicts.

Alternatively, you can examine the resources used by the EISA 
cards from within the ECU under Step 3: View or edit details, and 
move those that conflict with the ISA cards.

If your computer has more than 24 logical or physical disks, the 
ECU may fail. If this occurs, remove the extra disks and run the 
ECU. Then, reinsert the disks.

If you run the ECU under version 4.38 of the ARC firmware, be sure 
to save your EISA configuration when exiting the ECU, even if you 
have not made any changes to your setup. If you do not save your 
configuration each time, it will become corrupted and the ECU will 
have to be run again. This is an anomaly that applies only to 
version 4.38 of the ARC firmware.

PCI Parity Checking

Your computer is shipped from the factory with PCI parity checking 
disabled. This setting accommodates third-party adapter cards in 
your computer that either do not fully comply with the PCI 
specification or do not generate PCI parity. It is important to 
note, however, that parity checking is used to ensure data 
integrity, and leaving parity checking off increases the risk of 
generating data errors.

To turn on parity checking: 

1.  From the Boot menu, select Supplementary Menu. 

2.  At the Supplementary menu, select Set Up the System. 

3.  At the Setup menu, select Machine Specific Setup. 

4.  Use the arrow keys to highlight PCI Parity Checking Enabled, 
    then press Enter. 

5.  When asked to confirm your choice, select Yes and press Enter. 

6.  Press the Esc key three times to return to the Boot menu.

Note: If you observer PCI parity errors while PCI parity checking 
is on, disable PCI parity checking by following the same 
procedure, but select PCI Parity Checking Disabled instead.

Upgrading Firmware from CD-ROM

If you have version 4.24 or 4.38 of ARC firmware on your system, 
you cannot upgrade your firmware from CD-ROM. In these cases, copy 
the firmware upgrade files for your system to a diskette, and 
upgrade from there. This issue has been corrected in versions 
after 4.38.

Windows NT Installation Issues

Systems with Adaptec 2940UW or 3940UW SCSI Controllers

If your system has either the Adaptec 2940UW or 3940UW SCSI 
controller installed, it must not be connected to the boot hard 
disk (although it can be connected to non-boot disks). ARC 
firmware does not recognize these controllers and will not boot 
from drives connected to them.

In addition, you must install Service Pack 4 of Windows NT 3.51 
for Windows NT to recognize these controllers and the disks 
connected to them. If you are installing Windows NT 4.0, this
is not an issue - the Adaptec controllers work correctly

Disk Administrator Corrupts Partitions

When you install Windows NT (Server or Workstation) and start Disk 
Administrator for the first time, Windows NT will write a disk 
signature to the drives before opening the Disk Administrator 
window.

Note: If you want to preserve the formatting of a Digital UNIX or 
OpenVMS formatted disk, answer No when prompted to write a 
signature to these disks.

With Windows NT 3.51, the first time Disk Administrator is opened, 
drives and partitions appear correctly, but if you close and 
reopen it, some of the partitions are lost and incorrect 
information is displayed on the others. Alternatively, Disk 
Administrator can hang during initialization or the error message 
"The parameter is incorrect" appears.

This only happens if there are more than two logical drives in an 
extended partition when Disk Administrator attempts to write a 
fault tolerance signature. This problem will not occur if a 
signature is already present. Note that this issue does not apply 
to Windows NT 4.0.

It is possible for a system to remain functional after the 
partition table is corrupted. The nature of the corruption is such 
that partition table data is written to incorrect locations on the 
disk which may lie in the middle of user or file system data. 
Provided this information is not overwritten, the partition table 
entries may still identify the layout of the drives sufficiently 
well that Windows NT can continue to access the drives. However, 
this is an unstable situation and access to the partitions will be 
lost when the table entries are eventually overwritten. If the 
table entries overwrite existing data, user data or file system 
integrity are compromised immediately.

If you suspect that your partition table is compromised: 

1.  Back up critical data on the affected drive. 

2.  Install Windows NT Service Pack 2, 3, or 4. You can obtain the 
    Service Pack from:

    The Microsoft WWW site at http://www.microsoft.com/kb/softlib/winnt.htm. 
    Microsoft download service at 206-936-6735 (in the U.S.A.). 

3.  Repartition the affected disk and restore the backed up data 
    to the system.

MACH64 ISA Graphics Adapter

If your system has an ISA MAC64 graphics adapter installed, your 
system may crash during Windows NT Setup. To work around this, be 
sure to select standard VGA as your graphics adapter during setup, 
and then change your adapter type using Control Panel after setup 
has been completed.

Network Cards

Windows NT 3.51 includes an updated network adapter driver for 
Digital Equipment Corporation network adapters based on the 
DC21040 chip. Currently, this includes the DE425 and DE435 cards 
as well as built-in adapters. This new driver also supports many 
new Digital network cards, and has been significantly enhanced 
since the previous version.

The existing DC21040 driver is not automatically updated when 
upgrading to Windows NT 3.51 from Windows NT 3.5 or 3.1. If you 
are performing a fresh install of Windows NT 3.51, however, the 
latest driver is automatically installed onto your system. Refer 
to Updating the DEC DC21040 Adapter Driver for step-by-step 
instructions on correctly updating the driver. Note that this 
issue does not apply when installing or upgrading to Windows NT 
4.0.

Foreign Formatted or Unformatted Hard Disks

If you attempt to install Windows NT on a system with one or more 
unformatted or foreign formatted (i.e., UNIX or VMS) hard disks, 
Windows NT Setup might display an error similar to "Setup has 
encountered a condition which prevents the installation of NT" If 
this occurs, you must exit Windows NT Setup, and either:

Format the unformatted or foreign formatted disk(s) using the 
ARCINST utility as appropriate.

Disconnect the disk(s) from the SCSI controller until after 
Windows NT Setup is completed. Then reconnect the disk(s).



AlphaServer 2100A - Specific System Issues

In addition to the general system issues discussed in the General 
System Issues section, these system issues apply to all models of 
the AlphaServer 2100A.

S3-Based Video Adapters

Caution If you have a PCI video adapter with an S3 controller 
chip, the following information can prevent serious system damage.

There is a problem in the S3 controller that causes it to respond 
to PCI bus transactions that it should not respond to. As a 
result, this can cause excessive current along the bus, causing 
physical damage to the PCI-to-EISA bridge chip.

If you have an S3-based PCI video adapter, this problem can be 
avoided by placing the PCI S3 adapter in the bottommost PCI slot.

KZPSA SCSI Adapter

The KZPSA SCSI controller is only supported in the lower four PCI 
slots.



Important Notes for Owners of AlphaServer 2000, 2100, and 2100A Systems

There is a version conflict between certain revisions of the Mainboard, 
I/O module, ARC firmware, and Windows NT 4.0 HAL files that can cause 
your system to malfunction. Therefore, if you run Windows NT on any of 
the following systems, you must upgrade your ARC firmware to version 4.50
or later, and update your Windows NT 4.0 HAL files to the version posted 
on Digitals WWW site. The systems affected are:

o AlphaServer 2000 4/xxx and 5/xxx

o AlphaServer 2100 4/xxx and 5/xxx

o AlphaServer 2100A 4/xxx and 5/xxx

The methods you use to update the firmware and HAL are different depending 
on whether:

o Windows NT 4.0 is already installed.

o You are performing a fresh install of Windows NT 4.0.

o You are upgrading from Windows NT 3.51 to 4.0.

o You have just replaced your I/O module or mainboard, 
  and your system will not boot the ARC firmware.

Note: If you are already running ARC firmware 4.50 or later, you can skip
      the steps in the instructions related to upgrading the firmware. The
      ARC firmware version currently installed in your system is displayed 
      on the ARC Boot screen.

Note: If you are running ARC firmware 4.50 or later, do not downgrade to an
      earlier revision.

SYSTEM CONFIGURATION
---------------------

Setting the Operating System Type

If your system has never been set up for Windows NT, or if you are 
moving from another operating system to Windows NT, it is 
necessary to set the operating system type to Windows NT. Doing 
this causes the ARC, rather than the SRM, firmware to load when 
the system is initialized.

To set the operating system type: 

1.  Turn on the power to your computer. After a short wait, a blue 
    screen appears. 

2.  Press Enter. A >>> or P000>>> prompt appears. At this point, 
    you have booted into the SRM Console firmware. 

If the computer booted directly into the ARC Boot menu and you 
did not see the >>> prompt, the operating system type has already 
been properly set for use with Microsoft Windows NT. Skip to the 
next section, on updating the firmware. (If your system is a DECpc 
AXP 150, use the right Browse button to view firmware update 
information specific to your system.)
 
3.  Type the following two commands. Press Enter after each 
    command. 

    >>> set console graphics 
    >>> set os_type nt 

4.  Turn off the power to your computer. Wait at least 5 seconds, 
    then turn the power back on. 

The system performs several diagnostics. You can ignore any 
error messages because the remainder of the configuration 
procedure corrects any errors appearing at this point.



Updating the Firmware (All Systems Except DECpc AXP 150)

To learn about updating your firmware, read this section; however, 
if you have a DECpc AXP 150 system, use the right Browse button to 
view one of the following sections, which has information specific 
to your system.

For Windows NT to operate properly on your Alpha system, the 
minimum required revision level of the ARC firmware must be 
installed. 

If you have the required version, a firmware update is not 
required. However, updating to the latest version of the firmware 
is recommended to incorporate the latest firmware enhancements 
into your system.

Note If you are updating the ARC firmware on the AlphaStation 200, 
and are currently running the SRM firmware, you must issue the 
command set os_type nt at the SRM console before proceeding with 
the update. Not doing so will cause problems with the date and 
cause applications to fail.

Caution The following set of instructions will correctly update 
both the SRM Console firmware if applicable, and the Windows NT 
ARC firmware in your computer. While it is possible to update the 
firmware images independently, this is not advised because the 
firmware images in the firmware update kit are a matched set. When 
performing a firmware update:

o Update both the SRM and ARC firmware at the same time.

o Make sure that the SRM and ARC firmware come from the same update 
  kit.

To update the firmware: 

1.  When the ARC Boot Menu appears, note the version at the top of 
    the screen. Compare this version to the required version listed 
    earlier and determine if an update is required. If no update is 
    required, you can skip to the section Setting Default Environment 
    Variables, or update the firmware anyway to take advantage of new 
    features and bug fixes.
 
2.  If you are updating the firmware, select Supplementary Menu 
    and press Enter.
 
3.  Insert a diskette or CD-ROM containing the updated firmware 
    for your system model into the diskette or CD-ROM drive. 

4.  From the Supplementary menu, select Install New Firmware and 
    press Enter. The update utility begins loading. 

5.  After a few moments, the Firmware Update Utility screen is 
    displayed. Depending on your system model, either a UPD> or Apu-> 
    prompt is displayed. At the prompt, type update and press Enter. 
6.  When asked to confirm the update, type y and press Enter. 
 
    As the SRM and ARC firmware images are verified, a PASSED! or 
    Programming Completed message is displayed (the exact message 
    depends on your system model). If you do not see the message for 
    both firmware images, call the Digital Technical Support line at 
    1-800-354-9000 in the United States for further assistance. For 
    locations outside the United States, contact your local authorized 
    Digital partner.

Note On the AlphaStation 200 and 400, if you get a message that a 
jumper may not be set correctly, check the following jumper 
settings and correct them as necessary.

AlphaStation 200-J6, located on the right side of the memory SIMMs 
when viewed from the front of the system, should have pins 1-2 
jumpered.

AlphaStation 400-J4, located on the CPU module, should have pins 
1-2 jumpered.

7.  Once the update is complete, type exit at the prompt, then 
    press Enter. Then reset your system. 

When your system restarts, you are prompted to select a default 
language. For information on selecting a default language, see 
Selecting a Default Language.

    then turn the power back on. Any error messages appearing at this 
    point will be corrected by the remainder of the configuration 
    process.



Selecting a Default Language

The first time you power up after updating your workstations 
firmware, you are prompted to select a default language in which 
to display the firmware screens.

To select a default language: 

1.  When asked to select a default language, select either 
    English or Other Language as appropriate and press Enter. 

If you selected English, your workstation continues to the Boot 
menu. You can skip to Setting Default Environment Variables. 

If you selected Other Language, you are prompted for the 
location of the message and font files. Continue on to step 2. 

2.  Insert the diskette or CD-ROM containing the firmware message 
    and font files into the appropriate drive. If the files are 
    located on your hard disk, skip to step 3. 

3.  When asked to select the location of the message and font 
    files, select either Floppy Disk, CD-ROM, or Hard Disk as 
    appropriate, and press Enter. 

    The available languages are displayed on the screen. 

4.   At the Language menu, select the language of your choice and 
     press Enter. 

5.  The screen clears and you are asked if you would like to save 
    the language files to hard disk. Select Yes and press Enter.

Note If your hard disk has not yet been formatted, attempting to 
save the language files to the hard disk results in an error. For 
information on setting up your hard disk, see Hard Disk 
Preparation.

6.  You are asked to choose a hard disk location for the language 
    files. A default location will be selected. If you wish to use 
    this location, press Enter. 

    Otherwise, select Alternate Hard Disk Location and press Enter. 
    You are then asked to edit the partition and the directory 
    location of the language files. 

The language files are copied onto your hard disk, and the ARC 
Boot menu appears in the language you selected.

Note You can change the default language at any time by selecting 
Set Up the System from the Boot menu, then selecting Set Default 
Language and following the prompts.



Setting Default Environment Variables

These steps are necessary only if:

o Your system arrived from the factory without first being 
  configured.

o You are switching from Digital UNIX or OpenVMS to Windows NT.

You must know your disk configuration before performing these 
steps. If you are unsure about your disk configuration, go to step 
1 but select Display Hardware Configuration from the Supplementary 
menu instead of Set Up the System to display a summary of the 
hardware in your computer. Then return to the Supplementary menu 
and choose Set Up the System and follow the remaining steps.

To set default environment variables: 

1.  When the ARC Boot menu appears, select Supplementary Menu and 
    press Enter. At the Supplementary menu, select Set Up the System 
    and press Enter. 

2.  At the Setup menu, select Set Default Environment Variables 
    and press Enter. 

3.  When prompted to enter the system partition location, select 
    SCSI Hard Disk and press Enter. 

4.  When prompted to enter SCSI bus and SCSI ID numbers, enter the 
    SCSI bus and ID for the location of the system partition. These 
    values are used to set an environment variable, which Windows NT 
    uses to determine the correct drive and partition to boot from. 

If you are unsure about these values, accept the default values 
of 0. If these values are incorrect for your particular system (as 
is the case if your hard drives are on a secondary controller on 
SCSI bus 1), Windows NT Setup will prompt you to run the ARC 
Installation (ARCINST.EXE) utility. This utility will then provide 
valid values to choose from to set this environment variable 
correctly. 

5.  When prompted to enter the partition number for the disk, type 
    2 and press Enter. 

6.  Select Set Default Configuration and choose the floppy and 
    keyboard settings corresponding to your system.



Setting the EISA Configuration (Systems with an EISA Bus)

You must run the ECU if your system has an EISA bus and you have 
added, removed, or moved any EISA cards in your system. The ECU 
must be also be run if you are moving to Windows NT from Digital 
UNIX or OpenVMS.

However, if you dont have an EISA bus, you can skip this 
procedure and proceed with Hard Disk Preparation.

To set your EISA configuration: 

1.  Insert the ECU diskette for Microsoft Windows NT into the disk 
    drive. 

2.  At the Boot menu, select Set Up the System and press Enter. 

3.  At the Setup menu, select Run EISA Configuration Utility from 
    Floppy and press Enter. After a few moments, the EISA 
    Configuration Utility window appears. Press Enter to continue. 

If any of the EISA boards in your computer have not yet been 
identified, a Caution message box appears. You can press Enter and 
ignore this message because your boards will be identified in the 
following steps. 

4.  Press Enter to acknowledge any errors that are displayed. The 
    Steps in Configuring Your Computer dialog box appears. 

5.  Select Step 5: Save and Exit and press Enter. At the 
    confirmation dialog box, select Save the Configuration and press 
    Enter. When a message box appears notifying you that the 
    configuration has been saved, press Enter. The computer is 
    restarted with the updated information.



Hard Disk Preparation 

Microsoft Windows NT cannot read or write to disks formatted for 
the Digital UNIX or OpenVMS operating system. If your hard disks 
are formatted for either Digital UNIX or OpenVMS, you must 
partition and format all of your hard disks to either the FAT file 
system, NT file system (NTFS), or a combination of both file 
systems before installing Windows NT.

If your hard disks are already partitioned and formatted with 
either the FAT or NT file system, you can skip this group of steps 
and begin installing the Microsoft Windows NT software.
Caution If the hard disk you are going to partition currently 
contains any information you need, back that information up to 
another medium before proceeding. 

Skip this group of steps if you want to maintain your current 
partitions.

Note The version of Arcinst included with Windows NT 3.51 fails 
with an error code if you try to manipulate physical partitions or 
logical RAID units with a size value greater than 2024 megabytes. 
Note that this issue does not apply to the version of Arcinst 
included with Windows NT 4.0. 

The solution to this problem is to either:

Obtain the latest Arcinst utility from Digitals Windows NT WWW 
site at http://www.windowsnt.digital.com. This version does not 
have the size limitation.

Work with partition and RAID logical unit sizes of less than 2024 
megabytes.

Disk-Partitioning Information

The goal of the hard disk preparation instructions is to guide you 
through a fail-safe set of steps for creating two partitions of a 
particular size, in a particular order. By following these steps 
you will have the basic, recommended Windows NT partition 
arrangement.

Although you can create as many or as few partitions as you 
prefer, and create them in any order, there is an underlying 
reasoning for the recommended partitioning arrangement.

Note If you attempt to install Windows NT on a system with one or 
more unformatted or foreign formatted (i.e., UNIX or VMS) hard 
disks, Windows NT Setup might display an error similar to "Setup 
has encountered a condition which prevents the installation of 
NT" If this occurs, you must exit Windows NT Setup, and format 
the unformatted or foreign formatted disk(s) using the ARCINST or 
utility. Then restart Windows NT Setup.

Size and Order of Partitions

By following the instructions in the Hard Disk Preparation 
section, you create two partitions. The first (large) partition is 
6 megabytes less than the total size of the drive, and the second 
(small) partition consists of the remaining 6 megabytes. The large 
partition will hold the operating system and application/data 
files. The small partition, which must be formatted with the FAT 
format, holds the operating system loader and the few files 
necessary for your computer to boot. The small partition is called 
the system partition.

This arrangement provides two benefits:

Windows NT and the ARC standard require that a boot partition be 
formatted with the FAT file system. However, the Windows NT file 
system (NTFS) provides advantages over FAT, such as additional 
security and more efficient use of disk space. By keeping the FAT 
boot partition as small as possible, the maximum amount of space 
is left available for use as an NTFS partition.

Most applications attempt to install themselves onto drive C by 
default. Although the program installation drive is usually 
configurable by the user, many people accept the default of C. By 
making the first partition large, drive C becomes the larger 
drive. This arrangement makes program installation easier and 
provides disk space where you are likely to need it.

To partition your hard disk: 

1.  At the Boot menu, select Set Up the System and press Enter. 

2.  From the Setup menu, choose Manage Boot Selections and delete 
    all existing boot selections. 

3.  Insert the Microsoft Windows NT CD-ROM into your computers 
    CD-ROM drive. 

4.  At the Boot menu, select Run a Program and press Enter. You 
    are asked for the program to run. 

5.  Type cd:\alpha\arcinst and press Enter. The ARC Installation 
    Program screen appears. 

6.  Select Configure Partitions and press Enter. The available 
    disk-partitioning options appear. 

7.  Select Delete Partition and press Enter. The list of available 
    disks appears. 

If your computer has only one hard disk, press Enter. If your 
computer has more than one hard disk, select the disk to be 
prepared and press Enter. 

Depending on the previous disk configuration, you might be 
notified that no partitions exist, or you may see a list of one or 
more partitions. Follow the on-screen prompts to delete all 
partitions on the disk. 

8.  Select Create System Partition and press Enter. 
    When the list of available disks appears, select the disk to be 
    prepared and press Enter. You are prompted for the size of the 
    partition. 

9.  Type a number that is 6 megabytes less than the maximum size 
    displayed, then press Enter. For example, if the largest possible 
    value is 500, type 494. A partition of that many megabytes is 
    created. 
    When asked if you want to make this the system partition, type n 
    and press Enter. The partition is formatted. 
    Once the formatting is completed, press Enter. 

10.  Select Create Non-System Partition or Create partition (if 
     either of these choices are available) and press Enter. If the 
     only choice is Create System Partition, select it and press Enter. 
     When the list of available disks appears, select the same disk 
     and press Enter. You are prompted for the size of the partition. 

11.  Type the larger of the two values displayed (it will be close 
     to 6), then press Enter. The second partition is created. 

12.  After the partition is created, press Enter when prompted. 
     The partition is formatted. 
     Once the formatting is completed, press Enter. 

If you see a System Partition has already been defined 
message, it means that Windows NT has been previously installed. 
Type y to delete the existing system partition definition. 

13.  When the partitioning menu appears, select Exit and press 
     Enter. When the main Arcinst menu appears, select Exit again and 
     press Enter. The ARC firmware Boot menu appears.

Note If in step 10 above, the version of Arcinst you are using 
allowed the creation of a non-system partition, then skip to step 
19. If you could only create a system partition, you must follow 
steps 14 through 18 in order to arrive at the Digital-recommended 
partition arrangement. 

Steps 14 through 18 address an anomaly in the version of the 
Arcinst utility supplied by Microsoft with some versions of 
Windows NT. This version can only create system partitions. 
Because you can only have one system partition defined, it is 
necessary to remove the system flag from the large partition you 
just created.

14.  Select Supplementary Menu and press Enter. 

15.  Select Set Up the System and press Enter. 

16.  From the Setup menu, select Edit Environment Variables and 
     press Enter. 

17.  Next to Name:, type systempartition and press Enter. The 
     current system partition definition is displayed on the Value: 
     line. 

18.  Press the Home key to move the cursor to the beginning of the 
     system partition definition, and press the Delete key to delete 
     the text up to and including the semicolon (;). Once the text is 
     deleted, press Enter.

Caution Do not delete the text after the semicolon. If you 
accidentally delete any of this text, press the Esc key twice, 
then return to step 15.

19.  Press the Esc key to return to the Setup menu. Then select 
     Supplementary menu, save changes, and press Enter. 
     Your computer is now prepared for installation of Windows NT.



----------------------
INSTALLING WINDOWS NT
----------------------

Follow the steps in the procedure below to install Windows NT for 
the first time or to upgrade from an earlier version.

If you are upgrading Windows NT from Windows NT 3.1 or 3.5 to 3.51 
and you have a network adapter based on the DEC DC21040 chip, you 
must manually upgrade the adapter driver. After upgrading Windows 
NT, see Updating the DEC DC21040 Adapter Driver for more 
information. Note that this additional procedure is unnecessary if 
you are installing Windows NT for the first time or if you are 
upgrading to Windows NT 4.0.

If your system has a TGA graphics adapter installed, Windows NT 
Setup automatically installs the 2D graphics driver. The OpenGL 3D 
graphics accelerator libraries, however, are not installed as part 
of Windows NT setup. If you want full support for OpenGL 3D 
graphics, you must install the TGA driver after Microsoft Windows 
NT setup is completed. For more information, see Installing OpenGL 
3D Support.

If your system has an ISA MAC64 graphics adapter installed, your 
system may crash during setup. To work around this, be sure to 
select standard VGA as your graphics adapter during Setup, and 
then change your adapter type using Control Panel after Setup has 
been completed.

During Microsoft Windows NT installation, you are prompted for the 
location to install the Windows NT files. If you prepared your 
hard disk by following the instructions in Hard Disk Preparation 
section, install into the larger of the two partitions you just 
created and, when prompted, format that partition with the NT file 
system. If you are installing Windows NT onto a disk that was 
previously set up, install Windows NT into the same directory as 
the previous installation.

Because Windows NT searches the network for domain and other 
network information during installation, verify that your network 
controller is properly terminated and that the network cable is 
attached to the network controller before beginning to install 
Windows NT.

To install Windows NT: 

1.  Insert the Microsoft Windows NT CD-ROM into your CD-ROM drive. 

2.  From the ARC Boot menu, select Supplementary Menu and press 
    Enter. When the Supplementary menu appears, select Install Windows 
    NT from CD-ROM and press Enter. Windows NT Setup begins. 

3.  If a Hardware Support Disk (sometimes called an OEM 
    Installation Disk) was included with your system, make sure to 
    choose Custom Setup when prompted. Refer to the chart in the 
    Materials Needed section for information on which systems need a 
    Hardware Support Disk. 

    When the screen listing the recognized Alpha systems is 
    displayed, choose Other and follow the prompts to select your 
    system model. 

4.  Follow the prompts to complete setup of Windows NT.



Updating the DEC DC21040 Adapter Driver

If you have a network adapter based on the DEC DC21040 chip, the 
existing DC21040 driver is not automatically updated when 
upgrading to Windows NT 3.51. The updated driver must be installed 
manually after upgrading to Windows NT 3.51. Follow these steps to 
update Windows NT to version 3.51 and update the network driver. 

Note: These steps are unnecessary if you are upgrading to 
Windows NT 4.0, as the driver is correctly updated when upgrading 
to Windows NT 4.0.

Note: If you have previously installed Remote Access Services 
(RAS), note that the order of network protocol bindings might be 
changed by the following procedure, depending on the protocols you 
have installed. If you have RAS installed, it is recommended that 
you do either of the following:

Delete RAS services before following this procedure and then 
reinstall RAS afterwards

Note the order of your network bindings now and verify/correct 
them as necessary after following this procedure

To update the DEC DC21040 network adapter driver: 

1.  Start Windows NT and double-click the Network icon in the 
    Control Panel. The Network Settings dialog box is displayed. 

2.  If you are running TCP/IP protocol, double-click TCP/IP 
    Protocol in the Installed Network Software box. Write down all of 
    your TCP/IP configuration information displayed. This information 
    must be entered after the driver update. Choose Cancel when 
    finished. 

3.  In the Installed Adapter Cards box, select the card(s) for 
    which the driver is to be updated, then choose Remove. Choose Yes 
    in the confirmation message box. However, do not choose OK to exit 
    the Network Settings dialog box at this point. 

4.  Open a Command Prompt window and type the following commands: 
    cd /d %windir%\system32 
    dir oemnad?.inf 
    ren oemnad?.inf oemnad?.inx

Installing OpenGL 3D Support (Systems with TGA Graphics)

This information is relevant if your system uses TGA graphics.
After Windows NT is completely installed, you can install the 
OpenGL libraries. You must install the OpenGL libraries if you are 
using any software that takes advantage of the OpenGL 3D 
application programming interface (API) functions and you have a 
ZLXp-Ex video adapter. 

To install the OpenGL libraries for the ZLXp-Ex video adapter: 

1.  Insert the ZLXp-E (TGA) installation disk into the diskette 
    drive. 

2.  Within the Main program group of Windows NT, double-click the 
    Control Panel icon. 

3.  Double-click the Display icon.  

4.  Choose the Change Display Type button. 

5.  In the Display Type dialog box, choose the Change button. 

6.  In the Select Device dialog box, choose the Other button. 

7.  When prompted for the location of the driver files, verify 
    that drive A is selected and choose OK. Digital ZLXp-E will appear 
    in the list of devices. 

8.  Choose the Install button to install the driver. 

9.  When prompted, choose Yes to continue the installation. 

10.  When prompted whether to replace the existing driver, choose 
     New to use the version of the driver located on the diskette. 

11.  Choose Continue, then choose OK twice. 

12.  When prompted, choose the Restart Now button. 

13.  After Windows NT restarts, the display resolution will be 
     reset to 640 x 480. Use the Display applet within the Control 
     Panel to change the resolution if you prefer.
