________________________ CAUTION __________________________
Failure to properly set up the SCSI termination may result in loss of data or
damage to the file system.
___________________________________________________________

SCSI Termination
The AlphaStation 500 Series system contains an embedded SCSI bus that is used to
connect both the internal and external drives. Both ends (and only at the ends) of the SCSI
but MUST be terminated correctly.

External SCSI Connector Termination
An external terminator is required when the SCSI port is not being used.

Internal SCSI Termination
The internal SCSI cable used for the AlphaStation 500 Series is a flat ribbon cable with
integrated termination. Therefore, NO storage devices should have termination enabled.

SCSI Bus Length
The total SCSI bus length, including internal cables and etch on the motherboard as well
as the external cables between storage between the storage enclosures and the must not
exceed 3 meters (9.8 feet) for fast SCSI operation or 4 meters (13.1) feet for slow SCSI
(5MB/second). The AlphaStation 500 Series system’s internal SCSI length is 1.2 meters
(3.9 feet), leaving 1.8 meters (5.9 feet) available for fast SCSI use (2.8 meters [9.2 feet] for
external slow SCSI use).

Console Commands
Introduction
The AlphaStation 500 Series system contains two console subsystems:
•

Advanced RISC computing (ARC) firmware that supports the Windows NT operating
system

•

System reference manual (SRM) firmware that supports the Digital UNIX and
OpenVMS operating systems

The console firmware resides in 1MB of flashROM on the system board. FlashROM
memory can be updated in the field.
This appendix gives a basic description of commands for each console.

ARC Console
The ARC console supports the use of the Windows NT operating system. The ARC
console uses a menu interface. When an AlphaStation 500 Series system with Windows
NT is turned on, a menu similar to the following displays after initialization:
ARC Multiboot Alpha AXP Version 4.xx
Copyright (c) 1993 - 1995 Microsoft Corporation
Copyright (c) 1993 - 1995 Digital Equipment Corporation
Boot menu:
Boot Windows NT
Boot an alternate operating system
Run a program
Supplementary menu...

AlphaStation 500 Series User Information A-1

Console Commands
Use the arrow keys to select, then press Enter.
During initialization, the firmware checks the information stored in the nonvolatile
memory. If the information is unreadable or inconsistent, a warning message displays. The
warning message identifies the areas that must be fixed prior to booting Windows NT.

Commands You Need to Know
The sections that follow describe ARC console commands that you need to know.
Display Hardware Configuration
The Display hardware configuration command is located in the
Supplementary menu. Use this command to display information about:
•

Devices detected (and supported) by the ARC console

•

Alpha AXP processor revision, speed, and physical memory size

•

Video option detected

•

PCI slots, including vendor, revision, and device type

Set Default Environment Variables
The Set default environment variables command is located in the Setup
menu. Use this command to specify the location of the default system partition. For
example, when the partition is on a SCSI hard disk, you are prompted for the SCSI bus
number, the SCSI ID of the drive, and the partition number. These values set an
environment variable. Windows NT uses the environment variable to determine the correct
drive and partition to boot from.
You must know your disk configuration before performing these steps. If you are unsure
about your disk configuration, select Display hardware configuration from the
Supplementary menu. (See the previous section.)

When the ARC boot menu appears, select Supplementary menu, and press
[Enter]. Select Set up the system . . . and press [Enter].

Select Set default environment variables and press [Enter].

For the system partition location, select SCSI Hard Disk and press [Enter].

Enter the SCSI bus number (typically, 0) and the SCSI ID of the disk where the
partition resides.

A-2 AlphaStation 500 Series User Information

Console Commands
__________________________ Note _____________________________
If you are unsure about the environment values, accept the default values of 0. If
these values are incorrect for your system, (for example, if your hard disk drives
are on a SCSI bus 1, through a secondary controller), Windows NT setup will
prompt you to run the ARCINST utility. The ARCINST utility provides valid
values that you can use to set this environment variable correctly. (Refer to
Appendix E for information on running the ARCINST utility.)
____________________________________________________________
5.

Enter the partition number on the disk, which should be 2, and press [Enter].

Set Default Configuration
The Set default configuration command is located in the Setup menu. Use this
command to select:
•

Monitor resolution

•

Diskette drive capacity

•

Keyboard language

•

SCSI controller (host) ID (typically, 7)

•

EISA bus configuration

For example, when selected, the Set default configuration command prompts
you to make the following choices:

System Board Jumper Locations
Jumper pins allow you to set specific system parameters. Set them by changing the pin
location of jumper blocks. A jumper block is a small plastic-encased conductor (shorting
plug) that slips over the pins. To change a jumper setting, remove the jumper from its
current location with your fingers or small needlenose pliers. Place the jumper over the
two pins designated for the desired setting. Press the jumper evenly onto the pins. Be
careful not to bend the pins.
Figure C-1 shows the locations of the system board jumper pins. Table C-12 lists the
system board jumpers and factory-default settings.
________________________ CAUTION __________________________
Do not touch any electronic component unless you are safely grounded. Wear a
grounded wrist strap or touch an exposed metal part of the system unit chassis.
A static discharge from your fingers can result in permanent damage to
electronic components

________________________ CAUTION __________________________
If you boot from a Digital UNIX or Open VMS disk and also occasionally boot
Microsoft Windows NT Workstation 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 or Open VMS 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 or
Open VMS disks.
___________________________________________________________

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

Partition 1 (typically, the “C” drive) is the size of the disk less 10 MB and formatted
FAT. Normally, you select “convert to NTFS” during the Windows NT installation.

•

Partition 2 (typically the “D” drive) is 10 MB, formatted FAT, and identified as the
system partition.

Refer to Table F-1 for the steps to start installing Windows NT Workstation on a properly
partitioned and formatted disk.
_________________________ NOTE____________________________
The ARC console must be installed and running in order to perform a Windows
NT installation. If the SRM console is running, refer to Appendix E, Updating

Module Jumpers
The sound card uses jumpers located at J9 to select the motherboard sound routing and to
set the card’s bus address.
The TCE (timer-counter enable) jumper determines whether or not sounds generated on
the motherboard go to the speaker. The TCE jumper is factory-set to allow beeps to go to
the speaker (jumper in), as listed in Table G-4 below:

Sound Card Overview

External Connection Jacks
The rear-panel jacks are standard 3.5-mm stereo jacks.
Plugging a headphone into the headphone jack disables the speaker. You can plug a pair
of speakers into the headphone jack. (Amplified speakers are recommended.)
The microphone jack is for an electret microphone (2.2 Kohm to 2.5V).
You may use line-in and line-out jacks to connect receivers, amplifiers, or other audio
equipment.

Software
Before applications can use your sound card, the card must be known to your operating
system. Each operating system has a unique way of learning about the card. The
following section explain how to get this process underway for each operating system.

Microsoft Windows NT Workstation Operating System
To make the sound card available to Windows NT application, you must install and set up
the driver, as the following steps describe:
1.

From the Control Panel, select Drivers.

Click Add, and choose Windows Sound System from the list of drivers. Then
click OK. (If the driver is not present on the system disk, you may be prompted to
load Windows NT distribution media.)

The Windows Sound System Driver menu appears. Select Interrupt 7(IRQ7),
the default DMA channel, and the default I/O address.

Digital UNIX Operating System
The Digital UNIX operating system supports the sound card through Multimedia Services
for Digital UNIX, which is normally preloaded at the manufacturing site. The
manufacturing site also loads the sound card configuration information into the SRM
console configuration database. The information in the database is passed onto the
operating system.

G-4 AlphaStation 500 Series User Information

Sound Card Overview
Use the following command to verify that the sound card is loaded into the configuration
database:
>>>isacfg -all
You will know the sound card is loaded if you see a record with the handle “PCXBJ.”

Refer to the ISACFG section of Appendix A for more information.

Use the following command when you are logged in as “root” to verify that the
multimedia services are installed:
#setld -I |grep MME

installed
Look for the following response and verify that the word installed is present:
MMExxxxxx

installed

xxx xxx Audio Card Driver

Refer to the Multimedia Services for Digital UNIX AXP Installation Guide for
more information.
Digital’s multimedia application programming interface (API), which is included with the
Multimedia Services for Digital UNIX, is based on Microsoft’s Video for Windows
interface. This provides developers with a common API and supports for the same audio
and video file formats as Video for Windows does.

OpenVMS Operating System
The OpenVMS operating system contains a sound driver that supports the sound card.
Configuration information is stored in the SRM console configuration database.
Usually, the manufacturing site loads the sound configuration information into the SRM
console configuration database. The information in the database is passed onto the
operating system.
Use the following command to verify that the sound card is loaded into the configuration
database:
>>>isacfg -all
You will know the sound card is loaded if you see a record with the handle “PCXBJ.”

Refer to the ISACFG section of Appendix A for more information.
