Page 4 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade 4.0AM-137 SCSI TAPE AND HARD DISK DRIVE REQUIREMENTS The AM-137 board has an on-board high-performance SCSI interface that’s compatible with your AM-1600/1400 SCSI peripherals. The AM-137 board’s SCSI interface supports both SCSI-1 and SCSI-2 peripherals. With the AM-137 board installed, all of your SCSI peripherals will yield better performance, with SCSI-2 devices showing the greatest performance increase.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 5 TORX SCREWS Make sure the notch in the chip (indicating pin-1) points toward the rear of the drive. FIRMWARE PROM LOCATION MAC860 AM-626 PROM Installation 3.AM-627 and AM-628 Tandberg SCSI tape drives also require a firmware update to be SCSI-2 compatible. However, these drives use a flash ROM for their firmware, which can be updated without removing the drive from the computer.
Page 6 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade The program will prompt you for the name of the device, enter: STR0: RETURN The tape drive’s firmware will automatically be updated for SCSI-2 operation; it takes about one minute and the AMOS prompt will re-appear. In order for the firmware update to take affect, you must power the computer down and then turn the power on again. With the computer up and running, your tape drive will now be SCSI-2 compatible.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 7 Under AMOS 2.2 (or later) operating systems, you can divide your hard disk drive into logical devices larger than 32MB. In fact, you could take a 540MB drive and make it one giant 540MB logical. While this is perfectly acceptable, you may get a memory allocation error when running programs that load a copy of the bitmap into your memory partition—e.g., DSKANA and MONTST.
Page 8 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade In order to be AM-137 compatible, your bootable disk drive needs to have an AMOS operating system no earlier than AMOS 1.4C PR8/94 or AMOS 2.2C PR8/94. The easiest way to obtain this software is from the quarterly CD-ROM disc (Alpha CD). You must update your operating system before you install the AM-137 board. Load the AMOS 1.4C or AMOS 2.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 9 Your computer will boot using the TEST.MON file. After the computer has completed the boot process, make sure your computer is fully functional. Reboot the computer and do a complete check of your computer’s hardware—e.g., printers, magnetic tape drives, network hardware (if applicable), etc. After you are completely satisfied all your equipment is working perfectly, perform these commands: LOG SYS: RETURN COPY AMOSL.MON=TEST.
Page 10 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Use AlphaVUE to edit the AMOS32.INI file. Change the driver name in the first TRMDEF statement from AM13X to AM318. For example, change: TRMDEF TRM1,AM135=0:19200,AM65,100,100,100 to TRMDEF TRM1,AM318=0:19200,AM65,100,100,100 You are now ready to remove your AM-1600/1400 CPU board. Do not erase or modify your AMOSL.MON or AMOSL.INI files. By retaining these files, you will always be able to boot from your old CPU board.

This connector will support one AM-314 board, one AM-318 board, or one AM-366 board.
Page 18 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade How do you know what DB9 connectors attach to which DB9 cutouts? Notice how the cable leading to each of the DB9 connectors is marked: (P0, 4, 8, 12) (P1, 5, 9, 13) (P2, 6, 10, 14) (P3, 7, 11, 15) For the I/O cable attached to J4 on the AM-137 board: 1.The DB9 connector marked P0 attaches to DB9 cutout 0 or F1; 2.The DB9 connector marked P1 attaches to DB9 cutout 1 or F2; 3.The DB9 connector marked P2 attaches to DB9 cutout 2 or E1; 4.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 19 The B2/B1 location on the rear panel is actually an RJ21 cutout. Your AM-137 installation kit includes an adapter bracket allowing you to install two DB9 connectors into the RJ21 cutout. The adapter bracket and serial port assembly are shown below: AM-314 SERIAL PORTS MC1090 RJ-21 cutout on the rear of your Eagle chassis.
Page 20 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade 9.0SCSI BUS TERMINATION The high-performance SCSI bus on the AM-137 board must be terminated at each end. The AM-137 board provides termination at one end of the bus and the opposite end of the bus must also be terminated. This can be done by installing terminators in the SCSI peripheral located farthest down the cable away from the AM-137 board or by using an external terminator.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 21 11.0AM-137 BOARD BOOT SWITCH SETTINGS Just like your old CPU board, the AM-137 board has a switch that determines your primary and secondary boot device. The AM-137’s primary boot switches (switches 1 and 2) are factory configured to boot from a SCSI hard disk drive. The alternate switches (switches 3 and 4) are configured to no alternate device.
Page 22 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade 12.0AM-137 BOARD FIRST TIME BOOTUP With your new AM-137 board installed, it’s time to power up your computer. Plug a terminal cable into port #0 on your computer’s rear panel. Turn the computer’s power switch to the on position. As your computer boots for the first time, you will see a number of errors as the system initialization command file is processed.

Write buffering affords a significant performance improvement, but there are some things to consider before you enable this feature. Write buffering is described in detail in Appendix B. 3.
Page 24 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade As mentioned earlier, your AM-137 board has one I/O expansion connector at location J6.
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 25 12.1Enabling the SCSI Dispatcher Before you verify the TEST.INI file, you need to perform the PIC procedure to enable the SCSI dispatcher. Your new SSD chip must be installed. Once you enter the product installation code (PIC), the product overlay file is forever modified and will not accept a new PIC. This can be a problem if you happen to enter an incorrect PIC.
Page 26 Installation Instructions: AM-137 Board AM-1600/1400 Upgrade To execute the installation program, type: LOG SYS: RETURN OSINST RETURN The program will prompt you to enter the Product Installation Code (PIC). You must contact Alpha Micro to obtain the PIC code, which is based on the SSD chip in your computer’s main logic board. Type in your PIC. The program will prompt you as to whether you have entered the correct PIC code, once you confirm the PIC is correct press RETURN .
Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 27 13.0MAKING AN AM-137 COMPATIBLE WARM BOOT TAPE Once your AM-137 enhanced computer is up and running, you should create a warm boot tape. A warm boot tape provides a convenient way of accessing your SCSI drive should it ever fail to boot. An example of a typical routine for generating a warm boot monitor for a AM-137 enhanced computer is shown on the next page.

Installation Instructions: AM-137 Board AM-1600/1400 Upgrade Page 29 14.0OPERATIONAL NOTES Under normal operating conditions, the RUN light on destop computers (without AM-137 hardware installed) will remain lit at all times. With the AM-137 hardware installed and the system booted, you’ll notice the RUN light on your computer’s front panel may not be lit. This is because the AM-137 hardware uses the RUN light as an activity light and during periods of no activity the RUN light will go out.

If an error occurs at this point, try reloading the latest version of the system software. xd System bootup failed because of a time-out error. This code may indicate faulty memory or an addressing problem. 2E System bootup failed because of a bootstrap loader program checksum error. This code may indicate a bad PROM or bad memory.
APPENDIX A SCSI TERMINATION A.1SCSI TERMINATION USING EXTERNAL TERMINATOR OPTION The preferred method of terminating the SCSI bus in an AMOS based computer is the installation of an external terminator. In early April of 1993, the external SCSI bus terminator became standard on all AMOS based computer configurations.
Page A-2 Appendix A BAIL LOCKS CONFIGURATION A SI SC (PRA-00222-00) EXTERNAL SCSI BUS TERMINATOR CONFIGURATION B SI SC MAC821 #4 SCREW AND WASHER External Terminator Installation The illustration shows two different types of external SCSI connectors. 1.Configuration"A" shows an extended external SCSI connector and bail locks for holding the terminator in place. This configuration is used on several different models of computers sold by Alpha Micro, including AM-990 and AM-1600/1400 computers.
SCSI Termination Page A-3 A.1.1Termination Procedure (Without External Terminator) 1.For all AM-1600/1400 computers, the last SCSI device attached to the connector farthest down the cable away from the CPU board must have its terminators installed. If only one SCSI device is installed, that device must be terminated. 2.For subsystem installations, the last SCSI device attached to the connector farthest down the cable away from the host computer must have its terminators installed.

APPENDIX B READ-AHEAD AND WRITE BUFFERING B.1INTRODUCTION In the past, AMOS systems achieved high levels of performance by using a "Herbie" style disk controller (such as the AM-520) to offload a large portion of the overhead associated with disk access. One additional benefit of this offloading, is that extra cycles are available on the Herbie controller to perform functions such as read-ahead and write buffering.
Page B-2 Appendix B The data transfer path is much faster with the RISC SCSI-2 controller. It is able to read from or write to system memory 32 bits at a time, taking 150ns per read or write. The AM-520 transfers data 16 bits at a time, taking 210ns per 16 bit transfer. B.2READ AHEAD The AM-137’s SCSI disk driver, SCZRR.DVR, is able to perform read-ahead directly into AMOS disk cache.
Read-Ahead and Write Buffering Page B-3 When you use FIXLOG to create a driver for the AM-137 board, a new option will appear, which is the number of read-ahead blocks. For example, type: FIXLOG RETURN FIXLOG.LIT Version x.x(xxx) 1. Change the number of logicals 2.
Page B-4 Appendix B Another benefit of write buffering is it tends to eliminate duplicate disk writes, such as bitmap updates during operations such as copying files and tape restores and prevents head thrashing when reading through random access data files and writing a sequential file out to the disk (as most report generation programs do). B.3.
Read-Ahead and Write Buffering Page B-5 When specifying write buffering for a device, two files are loaded into system memory: .DVR and .WRC, 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 loaded into system memory.

APPENDIX C SUPER I/O Only AMOS 2.2C users can take advantage of Super I/O. AMOS 1.X operating systems do not support Super I/O. Super I/O, which requires a PIC (Product Installation Code), is designed to significantly increase character output for all serial ports using the AM318.IDV driver. This includes all AM-318 board serial I/O ports, as well as the AM137’s eight on-board serial ports. The more terminals you have on your system performing character output, the more you will benefit from Super I/O.
Page C-2 Appendix C If after entering the SERPIC command, the program responds by displaying a PIC, this indicates the encoding has already been completed. Nothing else needs to be done, assuming, of course, the PIC displayed matches the code given to you by Alpha Micro. This PIC is a unique identifier for your system that must be purchased and obtained from Alpha Micro. Enter the PIC, carefully verifying you have entered it correctly and press RETURN .
Super I/O Page C-3 2.Use AlphaVUE to modify your TEST.INI file. Locate the first AM318 TRMDEF statement. Disable Super I/O by adding /O (that’s an "O," not a zero) to the first AM-318 TRMDEF statement. For example, change: TRMDEF TERM2,AM318=0:19200,AM65,100,100,100 to TRMDEF TERM2,AM318/O=0:19200,AM65,100,100,100 3.Finish out of the AlphaVUE file by pressing Then press G and press the RETURN key. ESC to reach Command Mode. 4.The MONTST command will force your computer to boot from the TEST.INI file.
Page C-4 Appendix C 4.Now, you must add the /O switch to the very first TRMDEF statement that uses the AM318S driver. For example: TRMDEF TERM17,AM318S/O=20:19200,AM65,100,100,100 ESC to reach Command 5.Finish out of the AlphaVUE file by pressing G RETURN and press the key. The MONTST command Mode. Then type will force your computer to boot from the TEST.INI file. The /O switch will disable Super I/O only for the AM-318 boards using the AM318S driver.
APPENDIX D AM-137 BOOTABLE DISK DRIVES If your order included a new SCSI disk drive with a bootable copy of AMOS designed for your AM-137 upgrade, the drive will be clearly labeled with the following information: 1.Operating system loaded (either AMOS 2.2C or AMOS 1.4C) 2.Number of logicals the drive is divided into 3.Bitmap size 4.
Page D-2 Appendix D computer. Before downloading any of your existing software onto the drive, complete the following steps first: 1. Protect Your Data! Before doing anything else, make a complete backup of all the software on your bootable drive. Before you load any new software onto the bootable drive, make sure all the data is copied onto some form of backup media. Make sure you are able to read the data on your backup media; be absolutely sure the data on your backup media is restorable. 2.
