Eagle 450 Upgrade Instructions, Rev. A00
Chapter 1 - Introduction
The Eagle 450 is a powerful upgrade for certain Alpha Microsystems computers. Employing Motorola’s
new ColdFire technology, the AM-138 CPU board used in the Eagle 450 gives performance never before
available in an Alpha Micro mid-range computer.
The AM-138 board includes a Motorola ColdFire CPU, one or two memory SIMMs for up to 256MB of
memory, 10BaseT and AUI Ethernet interfaces, and either a narrow or Wide SCSI bus. It also offers
eight on-board serial I/O ports, a parallel port, and three I/O expansion slots for a total of up to 32 serial
ports.
The following computers can be upgraded with the AM-138:
•Eagle 100, 300, or 500
•AM-1600 in deskside chassis
The AM-138 board is supported only in the AM-1600/Eagle deskside chassis, either old or new
(introduced in the spring/summer of 1998) style.
Please contact your dealer or Alpha Microsystems for information on the different upgrade kits used for
each of these system types.
ABOUT THIS DOCUMENT
This document contains installation instructions for upgrading your computer with an AM-138 board.
Besides this introduction, its chapters include:
•Chapter 2 talks about what hardware and software works with the Eagle 450 upgrade, and what
doesn’t.
•Chapter 3 describes how to install RAM SIMMs and the AM-701 cache board on the AM-138.
•Chapter 4 covers AM-138 jumper settings and connectors, SSD installation, and more.
•Chapter 5 leads you through getting ready for the upgrade, updating your software, and
beginning the hardware installation.
•Chapters 6, 7 and 8 contain specific instructions for each type of upgrade: Eagle 100, Eagle 300
or 500, and AM-1600.
•Chapter 9 tells you how to test the new configuration and close the chassis.
•Appendices discuss important SCSI bus termination issues and using the read-ahead and write-
caching options.
In addition to this manual, you should have received a copy of the Eagle 450 Installation and
Technical Manual, DSO-00216-00. Keep that book handy during the upgrade procedure; these
instructions refer to it several times. It also includes details on the features and performance of
the AM-138 board and Eagle 450, and environmental and electrical requirements.

Eagle 450 Upgrade Instructions, Rev. A00
Chapter 2 - Compatibility
Before you proceed with your upgrade, it’s important to make sure you have all the hardware and
software you’ll need. This chapter discusses the hardware and software compatibility issues that may
arise during your Eagle 450 installation.
SOFTWARE COMPATIBILITY
To be compatible with the AM-138 CPU board, the operating system must be AMOS 2.3A, PR 10/98 or
later. You cannot use AMOS 1.x with the AM-138.
HARDWARE COMPATIBILITY
With one exception, the I/O and other peripheral circuit boards supported in other Eagle series computers
are compatible with the AM-138 board in your new Eagle 450. The one exception is:
•The AM-219 floppy controller board is not supported. A SCSI floppy drive is used instead (see
below).
For serial I/O, while we recommend the AM-318-10 as the best combination of features and port density,
the AM-314, AM-318-00, and AM-318-02 are also supported.
SCSI TAPE AND HARD DISK DRIVE REQUIREMENTS
The SCSI controller on the AM-138 provides two bus interfaces. One is a 50-pin SCSI bus interface, the
same as on the Roadrunner 030 and 040, Eagles, and the AM-4000. The second is a 68-pin Wide SCSI
bus interface, the same as on the AM-6000 and AM-6060. All devices must connect to one of the two
busses; the other connector cannot be used. You cannot attach peripherals to both busses in the same
computer!
Either SCSI bus will support the SCSI disk and tape devices in your current AM-1600 or Eagle. In
addition, you can attach Wide SCSI-2 drives to either bus, using the appropriate adapter to attach them to
the narrow bus.
The Eagle 450 upgrade kit comes in both narrow and Wide SCSI-2 versions. The narrow version uses
your existing SCSI cable and connectors; the Wide SCSI-2 version includes a new SCSI cable and
external connector.
For complete information on bus configuration, devices supported, and important termination rules,
please refer to Chapter 3 of the Eagle 450 Installation and Technical Manual. The following sections
briefly discuss some bus/device issues.
Never attach a device to or remove one from the SCSI bus while system power is on. The Eagle
450 SCSI bus uses tolerant active negation, which increases the probability that “hot plugging” a
SCSI device will damage the device, the SCSI controller, or both.

Page 4 Chapter Two
Eagle 450 Upgrade Instructions, Rev. A00
The SCSI Floppy Drive
Previous Alpha Micro computers, including the AM-1600 or Eagle you’re upgrading from, used a
separate floppy disk controller to interface to a diskette drive. The Eagle 450 does not support any of the
floppy controllers used in previous Alpha Micro systems (the AM-210, 212, 214, or 219). Instead, it can
use a SCSI floppy drive, the AM-212-20.
The AM-212-20 attaches to the SCSI cable like any other SCSI device. Though it is a 3.5” diskette drive,
it uses a 5.25” mounting bay.
SCSI Tape Drives
Any SCSI tape drive which works in your current AM-1600 or Eagle will also work in your upgraded
Eagle 450. No firmware revisions are necessary.
In order to warm boot from a Tandberg streaming tape drive, make sure you enter it as the alternate boot
unit ID in the CMOS Configuration Menu.
SCSI Hard Disk Drives
For optimum performance, use Wide SCSI-2 drives attached to the Wide (68-pin) SCSI connector.
Mixing SCSI-1, SCSI-2, and Wide SCSI-2 disks on the same bus tends to degrade performance and is
not recommended.
SCSI-2 Dispatcher
You must define a SCSI dispatcher in the system initialization command file. AMOS uses the dispatcher
to communicate with the SCSI controller chip. The dispatcher handles all communications with the SCSI
controller chip.
There are two versions of the SCSI dispatcher for the AM-138 board:
•SCZ138.SYS is a high-performance version of the SCSI dispatcher, which supports command
queuing, synchronous transfers, multi-threaded operations, and scatter-gather operations.
•SIM138.SYS is a simplified version of the SCSI dispatcher and does not support the high
performance features supported in SCZ138.SYS. You would use SIM138.SYS when making
warm boot tapes and for temporary situations with computers which have not had the AMOS
PIC code installed.
While both of these dispatchers support both narrow and Wide SCSI-2 devices, using the SCZ138.SYS
dispatcher increases system performance greatly, and allows you to use DCACHE and write cache
efficiently. SCZ138.SYS also supports several option switches to let you modify its performance, as
described in Chapter 5.
Please refer to Chapter 5 for instructions on enabling the Eagle 450’s SCSI dispatcher.

Eagle 450 Upgrade Instructions, Rev. A00
Chapter 3 - Upgrading Eagle 450
On-Board Memory
The AM-138 has two on-board SIMM (single inline memory module) expansion slots, which support
60ns DRAMs. Because the memory is located on-board, it can be accessed much faster than memory
accessed over the VME bus—i.e., AM-730 and AM-740 memory boards used with earlier CPU boards.
The AM-138 also supports one 64KB cache SIMM (the AM-701). This SIMM is installed in the same
way as the memory SIMMs.
The following procedures describe how to install and remove the memory and cache SIMMs, and set the
memory size jumpers. They are referred to in the appropriate place in the upgrade instructions in
Chapters 6, 7, and 8. Do not attempt install any SIMM until you reach the appropriate place in the
installation procedure for your configuration.
ELECTRONIC EQUIPMENT HANDLING PRECAUTIONS
While your computer's hardware is exposed and the AC power cord is unplugged, the
components are vulnerable to damage caused by static discharge. Your body and clothing are
capable of storing an electrical charge that can damage or destroy unprotected electronic
components. Before you handle any computer hardware, make certain your work area is properly
protected against static discharge. There are a number of commercially available static protection
devices, like the wrist strap shown below, designed specifically to protect your equipment from
harmful static discharge.
Figure 3-1: ESD Wrist Strap

Eagle 450 Upgrade Instructions, Rev. A00
INSTALLING THE EXTERNAL CACHE SIMM MODULE
The external cache SIMM must only be installed in the J12 slot, labeled CACHE SIMM. Never
install memory expansion SIMMs in J12, or the cache SIMM at any other location. See Figure 4-
1 for the location of J12.
To install the 64KB external cache SIMM (PDB-00701-00) on the AM-138 board:
3. Align pin-1 on the external cache SIMM module with pin-1 on connector at J12. Pin-1 on the
SIMM module is on the notched end of the module (see Figure 3-2 below).
4. Insert the cache SIMM module into the J12 connector at a slight angle.
5. Rotate into the upright position.

The cache SIMM will engage the metal retainer clips and click into position, locking in place. When
properly installed, the components on the cache SIMM module will be facing away from the other
memory SIMMs.
To enable the cache, make sure the jumper at location JP12 is installed. This is the factory default.

Upgrading Eagle 450 On-board Memory Page 7
Eagle 450 Upgrade Instructions, Rev. A00
INSTALLING MEMORY
The Eagle 450 supports from 4MB to 256MB of main memory: either one or two memory SIMMs of
4MB, 8MB, 16MB, 32MB, 64MB, or 128MB. Use 60ns SIMMs only; 70ns SIMMs will not work.
Unlike the AM-6000, SIMMs do not have to be installed in pairs: you can use either one or two SIMMs;
if you use two, they do not have to be of equal size. For example, you can install one 32MB SIMM and
one 16MB SIMM for a total of 48MB of memory.
The memory SIMMs install in connectors J10 and J11. See Figure 4-1 for the location of these
connectors. If you’re installing only one SIMM, it goes in J10. If you’re installing two SIMMs of
unequal capacity, the larger one goes in J10.
To install memory expansion SIMMs on the AM-138 board, use this procedure:
Remember, don’t follow this procedure until you’re at the proper place in the installation process
for your upgrade.
1. Insert one SIMM (the larger if the SIMMs aren’t of equal capacity) in connector J10. Align pin-1
at the notched end of the SIMM module with pin-1 on the connector, as in Figure 3-2.
2. Insert the SIMM module into the connector at a slight angle.
Rotate into the upright position.
The SIMM will engage the metal retainer clips and click into position, locking the SIMM in
place.
3. If you are using two SIMMs, repeat steps 1 and 2 for the second one, at connector J11.
Setting Memory Jumpers
After installing the SIMMs, set the jumpers at location JP7 on the AM-138 board according to the table
below. As you turn on the computer, AMOS will automatically make the memory available. See the
diagram of the AM-138 in the next chapter for the location of the JP7 jumpers.

AM-138 BOARD ILLUSTRATION
Your AM-138 board has been factory tested and shipped with its configuration jumpers set in their
standard default positions. There are only two areas on the board which may require you to change
jumper settings:
•Memory size select (JP7)
•Enabling or disabling the supply of SCSI bus termination voltage (JP3)—default set at enabled.
All other jumpers should be left in their factory-installed positions. You may want to check your board
before installation to make sure all jumpers are properly installed.
The AM-138 board is shown in Figure 4-1. The illustration is followed by a jumper configuration table,
showing the default setting for each jumper, and a table defining the various connectors on the board.

Eagle 450 Upgrade Instructions, Rev. A00
THE CMOS MENU
The Eagle 450 does not use boot ID switches; instead it has a CMOS configuration menu to let you
choose primary and secondary boot devices, as well as set other system options, such as the system
monitor file to use. After installing the AM-138, as described later in this document, you can access the
CMOS menu before booting the new computer for the first time. You’ll need to do this if you aren’t
using the default boot configuration. The default settings are:
•Primary boot device: Disk at SCSI ID 0
•Secondary boot device: Streamer tape at SCSI ID 3
•Monitor file name: AMOS32.MON
•Initialization file name: AMOS32.INI
•Network interface: TPI
•Serial port 0 speed: 19.2K baud
•Boot messages on console?: Yes
For information on changing the CMOS configuration , please refer to Chapter 4 of the Eagle 450
Installation and Technical Manual.
ETHERNET PORTS
The AM-138 boards contains both AUI and 10BaseT Ethernet connectors. These connectors use the
same Ethernet controller, so performance is the same with both. Use whichever matches your network
cabling.
You cannot use both Ethernet connectors at the same time. Attempting to use the Eagle 450 as a
gateway between two physical networks will not work.
To use the AM-138’s Ethernet port, you'll need Alpha Micro's networking software, AlphaTCP, which is
included with AMOS 2.3A and later. There are two software drivers for the AM-138's Ethernet port:
AM138.LDV, which is only TCP compatible (and supports ITC tunneling) and AM138.NDV, which is
AlphaNET compatible. In most configurations, AM138.LDV provides better performance.
For instructions on configuring AMOS to use the AM-138 Ethernet port, please see Chapter 5.
Additional information on configuring your networking software and hardware is in the AlphaTCP
Administrator’s Guide, DSO-00187-00.
REMOTE RESET CAPABILITY
The AM-138 board has an option to enable remote hardware reset, either through serial port 0, or by
using the Remote Reset Adapter, PDB-10323-00.
You cannot use remote reset through port 0 if port 0 uses an AM-90 card for its back panel
connection; the AM-90 does not support this feature. If you use an AM-90, which we
recommend, you must use the Remote Reset Adapter if you want remote reset ability.

Page 14 Chapter Four
Eagle 450 Upgrade Instructions, Rev. A00
To enable remote reset through serial port 0, you must do two things:
1. Install the JP1 jumper. The factory default is not installed.
2. Connect a push-button switch between pin-1 and pin-7 (signal ground) at the terminal end of the
terminal cable attached to serial port 0.
Once you’ve enabled remote reset, you can reset the computer by activating the push-button switch.
The remote reset adapter allows you to reboot the computer from anywhere in your facility by wiring an
external switch to the location you want. To install the remote reset adapter, follow the instructions in
PDI-10323-00. The JP1 jumper must not be installed. Attach the adapter’s single-wire connector to the
connector labeled RESET at location P8. Attach it to the pin away from the edge of the board.
INSTALLING THE SSD CHIP
If you are upgrading from an Eagle 100, 300 or 500, you must remove the SSD chip from your existing
computer and install it in on the AM-138. If you are upgrading from an AM-1600, your upgrade kit
includes a new SSD chip, which you must install in the AM-138.
Removing the SSD requires a special tool. See the illustration below for more information.
The SSD chip and boot
PROM on the AM-138
board require a
specialized tool for
their removal. If you
attempt to remove
the SSD chip or
boot PROM using
a screwdriver or
pocketknife, you
could easily damage
both the chip and the
socket. This type of chip
extraction tool is available
at retail stores specializing
in electronic components.
