INTRODUCTION PREFACE The Bootstrap Loader enables you to generate a system that can bootload from Intelsupplied or custom devices. A bootable system gains control immediately after power-up or system reset. This manual provides information that enables you to configure your system to boot from specific devices, to include your own custom device drivers as part of the system, and to place your generated system into PROM devices. READER LEVEL The manual assumes that you are familiar with the iRMX® Operating Systems and an editor with which you can edit source code files. It may also be helpful if you are familiar with the following: • SUBMIT files. • ASM source code files. MANUAL OVERVIEW The descriptions in this manual apply to both the iRMX I and the iRMX II Operating Systems. Differences, where they exist, are highlighted in the text. This manual is organized as follows: Chapter 1 This chapter provides an overview of the Bootstrap Loader operations. Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 Chapter 7 Appendix A Bootstrap Loader This chapter provides an operator's viewpoint of using the Bootstrap Loader. This chapter describes how to configure the first stage of the Bootstrap Loader. This chapter describes how to configure the third stage of the Bootstrap Loader. This chapter describes how to write custom first-stage drivers. This chapter describes how to write custom third-stage drivers. This chapter describes error handling procedures. This appendix describes how to include automatic boot device recognition into your system. v
PREFACE Appendix B This appendix describes how to load the Bootstrap Loader and the monitor into PROM devices. Appendix C This appendix describes use of the D-MON386 monitor in the Bootstrap process. CONVENTIONS vi The following conventions are used throughout this manual: • Information appearing as UPPERCASE characters when shown in keyboard examples must be entered or coded exactly as shown. You may, however, mix lower and uppercase characters when entering the text. • Fields appearing as lowercase characters within angle brackets ( < > ) when shown in keyboard examples indicate variable information. You must enter an appropriate value or symbol for variable fields. • User input appears in one of the following forms: as blue text as bolded text within a screen • The term "iRMX II" refers to the iRMX II (iRMX 286) Operating System. • The term "iRMX I" refers to the iRMX I (iRMX 86) Operating System. • The terms "iRMX" or "iRMX Operating System" when used by themselves, refer to both iRMX I and II, that is, the text applies equally to both operating systems. • All numbers, unless otherwise stated, are assumed to be decimal. Hexadecimal numbers include the "H" radix character (for example, OFFH). Bootstrap Loader ,I
