CHAPTER 3 AM-3000M/LC Hardware Installation 3.1HARD DRIVE CONSIDERATIONS Whether you’re installing a new pre-configured Roadrunner bootable SCSI disk drive, or you’re going to use your existing hard drive as the main system boot drive, there are certain considerations that must be taken into account before proceeding with the actual hardware upgrade.
PAGE 33
Page 3-2 AM-3000M/LC Hardware Installation 3.1.2Attaching Hard Drives to Opposite Bus Ports On a standard AM-3000M you may attach a SCSI hard drive to the opposite SASI/SCSI port and treat it much the same as a sub-system drive. That is, if your system is booting on the Roadrunner’s SCSI port, you could create a disk driver using FIXLOG and SCZDVR.DVR to access a SASI/SCSI-1 hard drive on the CPU SASI port. Or, if you’re booting on the SASI port, you could create a disk driver using FIXLOG and SCZRR.

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.

This configuration is used on several different models of computers sold by Alpha Micro, including AM-990 and AM-1600 computers.
PAGE 68
SCSI Termination Page A-3 A.1.1Termination Procedure (Without External Terminator) For all Alpha Micro computers without an external terminator, 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. A.
PAGE 69
Page A-4 Appendix A 3.If a computer with one or more SCSI peripherals is cabled to a subsystem with additional SCSI devices, the SCSI devices in the subsystem should be configured so they do not supply termination power. Ideally, you want the SCSI host controller in the main system to be the sole source of termination power. The termination power guidelines described above are valid even when you are using SCSI peripherals that do not support SCSI-2 protocol.

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 72
Page B-2 Appendix B B.2READ AHEAD The Roadrunner’s SCSI disk driver, SCZRR.DVR, is able to perform read-ahead directly into AMOS disk cache. When any program attempts to read a physical block from a disk, the SCZRR driver will also read up to an additional seven sequential blocks from the disk drive and store these read-ahead blocks in the cache. This read-ahead scheme works very well when jobs on the system are doing a large number of sequential reads.
PAGE 73
Read-Ahead and Write Buffering Page B-3 If you wish to disable or change the number of read-ahead blocks, simply use the FIXLOG program to generate a new disk driver and if the disk driver is for the DSK: device, don’t forget to use MONGEN and embed the new driver into the system monitor. The generic Roadrunner SCSI disk driver SCZRR.DVR is set up for seven read-ahead blocks. B.
PAGE 74
Page B-4 Appendix B Therefore, you must weigh the potential for data loss (which is always there) versus the dramatic performance increase seen when using write buffering. If you are worried about the reliability of write buffering, it may be worth keeping in mind that the AM-520 disk controller has always used write buffering on a track-by-track basis (not quite as efficiently as the Roadrunner write buffering scheme however). The SMARTDRV program that comes with MS-DOS 5.
PAGE 75
Read-Ahead and Write Buffering Page B-5 This would set up 100KB of write buffering for the DSK devices and 100KB of write buffering for the SUB device. All three drives would have their write buffers flushed every minute (or sooner if the drives are not busy with read requests). B.4FINAL NOTES Both read-ahead and write buffering schemes used on the Roadrunner hardware dramatically improve system performance in our lab tests.

APPENDIX C ROADRUNNER SOFTWARE CONFIGURATION C.
PAGE 79
Page C-2 Appendix C C.2.1Warm Boot Ability A warm boot tape allows you to access the computer in situations where you are not able to boot from the hard disk drive. When doing a Roadrunner upgrade, you’ll be modifying the system initialization command file and using the MONGEN program to embed a new driver in your AMOS monitor. Either of these two operations, if done incorrectly, could result in a computer that won’t boot.
PAGE 80
Roadrunner Software Configuration Page C-3 If your disk drive is running an operating system earlier than AMOS 1.4C PR5/95 or 2.2C PR5/95, you will need to update your operating system. You must update your operating system before you install the Roadrunner hardware. Load the new operating system, then overlay the Product Support Software Kit designed for the Roadrunner 040 upgrade. C.3.
PAGE 81
Page C-4 Appendix C C.3.2Booting from the Roadrunner SCSI Port Before you turn off power to your computer and install the Roadrunner hardware, you need to make a couple of adjustments for Roadrunner compatibility: Instructions outlined in this section require that you directly modify your AMOS monitor, as well as your AMOS system initialization command file. These files are being modified directly to allow the computer to boot from the new Roadrunner hardware once it is installed.
PAGE 82
Roadrunner Software Configuration Page C-5 For example: :T JOBS 1 JOBALC ; TRMDEF VER SCZDSP ; DEVTBL JOB1 TERM1,AM140=0:19200,AM62A,100,100,100,EDITOR=15 SCZRR.SYS DSK1,DSK2 3.Once the dispatcher has been defined in your AMOS32.INI file, you must code the SCSI dispatcher to allow it to run on your specific system. 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 83
Page C-6 Appendix C 4.Your computer boots from a monitor called AMOS32.MON. In order for the Roadrunner to boot, a new monitor must be created by embedding a driver called SCZRR.DVR, which is compatible with the Roadrunner SCSI port. The boot monitor used by the Roadrunner is also called AMOS32.MON. The Roadrunner’s high performance SCSI port supports write buffering for SCSI hard disk drives.

APPENDIX D ROADRUNNER AM-174 PROGRAMMING INFORMATION D.1ROADRUNNER AM-174 PROGRAMMING INFORMATION The MC68040 processor used on the AM-174 Roadrunner board contains more internal instruction cache (4096 bytes) than earlier MC68040-based processors. Increased internal cache is one of the features which contributes to the improved performance of the Roadrunner 040 board; however, if your software does not properly manage this instruction cache, it could be adversely affected.
PAGE 86
Page D-2 Appendix D D.1.2What You Must Do.. The only sure way to address this issue is to flush the instruction cache after loading instructions into memory, but before executing those instructions. Because the method by which you flush the cache is different on the various 680x0 processors, you will need to add code specific to the 68040. You must be certain to handle the different processors individually. Failure to do so may result in inadvertently disabling certain processor features.
PAGE 87
Roadrunner AM-174 Programming Information Page D-3 In versions of M68 appearing in earlier AMOS releases, the instructions MOVECD7,CACR and CINVA were not implemented. With the release of AMOS 2.2C, which includes M682.0(181), these instructions are now supported. Examples of their use are shown above. D.1.3One More Caution The 68040 also has internal registers called Transparent Translation Registers (also present on the 68030) that you must be sure not to modify.
PAGE 88
Page D-4 Appendix D From the AMOS prompt, you can type: COMPAT COMPAT.DAT RETURN or you can add this same command into your system initialization command file. If you simply enter the command: COMPAT RETURN you will get a display showing the list of programs that have been selected for the special cache control.
