INTRODUCTION
General Information
This chapter explains what SCSI is and what the SBC SCSI Software does to
support SCSI-related hardware on selected Single Board Computers (SBCs). It
also explains the meanings conveyed by the variety of fonts and special text
symbols found throughout this manual. Most importantly, it assists in finding
desirable information on these pages and elsewhere.
Notes
This userÕs manual documents the SBC SCSI Software
Release 1.1. It does not necessarily apply to the release
superceded, which was known as the MVME167/187 SCSI
Software R10V1.
Throughout this manual, the term Single Board Computer
(SBC) refers to any of the MVME162/162LX/166/167/187/197
series of CPU boards.
Organization of This Manual
Here are some short descriptions of the remaining chapters in this manual:
❏ Chapter 2 provides an overall perspective of the core of the SBC SCSI
Software, which is referred to as the SCSI I/O Processor (SIOP) Firmware
(or just Firmware).
❏ Chapter 3 details the programming interface used to invoke the Firmware.
❏ Chapter 4 explains the special tools (NCR Build Tools) used to build the
Firmware from source and how it must be prepared for its run-time
environment.
❏ Chapter 5 covers additional special topics such as the debug logging
facility and certain run-time considerations.
❏ Appendix A maps out the directory structure of the SBC SCSI Software
release media.
❏ Appendix B specifies the data structures used to communicate with the
SIOP Firmware via its programming interface.
❏ Appendix C describes the external routines which must be provided, with
C-language interfaces, in order to compile and use the Firmware.
❏ Appendix D catalogs the FirmwareÕs run-time returned error conditions.
❏ Appendix E documents a demo (test) program which illustrates the use of
the SBC SCSI Software and can be used to verify its functionality.
❏ The Glossary explains terminology often used when discussing the SBC
SCSI Software.
