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.
Page 2 Chapter One Graphic Conventions Like other Alpha Micro documents, this manual uses some standard symbols and special typefaces to make our examples and explanations easier to read and understand: Symbol Description This means STOP!, and signals an important warning or restriction. Be sure to read the text next to this symbol carefully, as it could help you avoid serious problems. This marks a hint—a shortcut or an easier way to do something.
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.
Page 4 Chapter Two 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.
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.
Page 6 Chapter Three 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 41 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.
Upgrading Eagle 450 On-board Memory Page 7 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.

Chapter 4 - Configuring the AM-138 This chapter contains information you may need both before and after installing your Eagle 450. It covers: • Jumpers and connectors on the AM-138 board • CMOS setup • Ethernet interface options • Remote reset capability • Installing the SSD chip • On-board serial ports • Front panel status display codes • UPS monitoring information We recommend that you safeguard your computer components by insuring that your work area is properly protected against static discharge.

See page 13.
Page 12 Chapter Four AM-138 Connectors The following table provides a brief overview of the connectors on the AM-138 board.
Configuring the AM-138 Page 13 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.
Page 14 Chapter Four 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.
Configuring the AM-138 Page 15 Before installing the SSD chip in the AM-138, write the SSD number in a secure place for future reference. Install the SSD at its clearly marked socket at U34 (see Figure 4-1), by inserting and pressing down gently on the chip. Make sure you align pin-1 on the SSD chip with the SSD socket. ON-BOARD SERIAL PORTS The AM-138 contains eight on-board serial ports. These are standard, fully functional ports, to which you can attach any supported terminal, printer, or modem.
Chapter 5 - Beginning an Eagle 450 Upgrade When you upgrade your computer to an Eagle 450, it’s important that you perform the proper hardware and software steps in the correct order, taking all the necessary precautions to protect your data in case of a problem. Here is a brief summary of the steps you must follow to complete your upgrade: 1. Safeguard your data by performing a complete backup and preparing and testing a warm boot tape. 2.
Page 18 Chapter Five STEP 1 - PROTECTING YOUR DATA Perform a Complete Back Up When doing a major upgrade to a computer, you want to be absolutely sure you have a recent and complete system backup. Although it is very unlikely that data stored on your hard disk drive would be corrupted when upgrading your computer, you should be prepared for anything. Before you loosen the first screw or download any new software, make sure all your data is copied onto some form of backup media.
Beginning an Eagle 450 Upgrade Page 19 STEP 4 - CREATE A NEW SYSTEM MONITOR Because of the Eagle 450’s CMOS configuration, you can give the system monitor file any name you want. So, you can create a monitor to use after the AM-138 board is installed without affecting the way your system performs now. Use MONGEN to create a monitor called AM138.MON, containing the SCZ138 disk driver. For example: LOG SYS: ENTER MONGEN ENTER Input monitor name: AMOS.MON ENTER New disk driver: SCZ138.
Page 20 Chapter Five For example, if the QUEUE statement in your system initialization command file is currently set to 200 and the JOBS statement is set to 50, the resulting formula would look like this: New Queue Block Requirement = 200 + (13 x 50) This example results in a setting of 850 queue blocks. However, we strongly recommend that you use a minimum a 2,500 queue blocks, even if the formula results in a lower number. 5.
Beginning an Eagle 450 Upgrade Page 21 The most common of the other switches is /EW, to enable Wide SCSI operation when using the optional Wide SCSI bus. If you have both Wide and narrow SCSI devices attached to the Wide bus, enable Wide SCSI operation only for the Wide devices.
Page 22 Chapter Five STEP 7 - NETWORK CONFIGURATION In step 5, you changed a SYSTEM statement in the AM138.INI file to load the correct network interface driver for the Eagle 450 Ethernet port you will be using. You must make the same change to the AlphaTCP configuration file, CONFIG. To do this: 1. Log to TCP:. 2. Edit the CONFIG. File. 3. Change the IFCONFIG statement to AM138.LDV. 4. Save the file. If the Eagle 450 won’t be using AlphaTCP, you can skip this step.
Chapter 6 - Eagle 100 Upgrade Hardware Installation In this upgrade the AM-138 replaces the AM-137 CPU board. This upgrade procedure involves removing the old CPU and rear panel and installing the AM-138 and a new rear panel. The following instructions walk you through this process. PREPARING FOR THE UPGRADE Before starting the hardware upgrade, make sure you have completed all of the steps in Chapter 5, "Beginning an Eagle 450 Upgrade.

Make sure pin-1 orientation is correct for all cable connections. 7.
Chapter 9 - Testing the New System After you’ve installed the new hardware, you need to test the system to make sure it works properly in its new configuration. To do so: 1. Run self-test. 2. If the system passes the self-test, access the CMOS Configuration menu to define your configuration, then boot the computer. Make sure it boots correctly with your new configuration. 3. Rename your new system monitor and initialization files. 4. Back up the entire system and make a new warm boot tape.
Page 54 Chapter Six To check on the status of all jobs, we recommend that you type: STAT ENTER RENAMING THE SYSTEM MONITOR AND INITIALIZATION FILES Once the system has passed the self-test and you have made sure that all jobs are up and running: 1. Make archive copies of your previous monitor and initialization files. For example: LOG SYS: ENTER COPY OLDMON.MON=AMOS32.MON COPY OLDINI.INI=AMOS32.INI ENTER ENTER 2. Rename the AM138.MON and AM138.INI files to AMOS32.MON and AMOS32.INI: COPY AMOS32.
Appendix A - SCSI Termination SCSI TERMINATION USING EXTERNAL TERMINATOR The preferred method of terminating the SCSI bus in an AMOS based computer is the installation of an external terminator. In April 1993, the external SCSI bus terminator became standard on all AMOS computers. Using an external terminator makes installing an add-on subsystem (like a portable CD-ROM drive) easier, eliminating the need to remove terminators from a SCSI device located in the host computer.
Page 56 Appendix A Figure A-1 shows an extended active external narrow SCSI connector and bail locks for holding the terminator in place. The terminator is installed by sliding it over the connector and then latching the bail locks into the notches in the terminator. ATTACHING EXTERNAL DEVICES To attach an external SCSI device, you must remove the terminator from the external SCSI port. However, you must make sure the SCSI bus is still terminated at both ends.
Appendix B - Read-ahead and Write Buffering The AM-138 board uses a programmable RISC DMA controller for SCSI bus communications and for data transfer to and from the AM-138's SCSI bus. The ColdFire CPU is only involved with setup before and cleanup after a SCSI command is sent to a devicethe rest of the command, including data transfer, is handled by the RISC processor.

ENTER To save the driver you have created, type: SAVE DSK.
Read-ahead and Write Buffering Page 59 Potential Pitfalls Obviously, there can be problems with write buffering, especially if the system either crashes or is powered off while writes are pending in the write buffer. If that happens, all pending writes are lost. Though this sounds like a major problem, it can also happen if write buffering is not enabled. However, write buffering increases the number of writes at risk.
Page 60 Appendix B When specifying write buffering for a device, two files are placed into system memory: .DVR (loaded from disk) and .WRC (directly created in system memory), which are the driver and cache buffer. This is true for all SCSI disk devices except the DSK device. For the DSK device, the file DSK.DVR does not need to be created because it is already loaded into the system monitor. Therefore, for the DSK device, only the file DSK.WRC will be created in system memory.
