DIAGNOSTIC FIRMWARE GUIDE
6.1 INTRODUCTION
This diagnostic guide contains operation information for the CPU32Bug Diagnostic Firmware
Package, hereafter referred to as CPU32Diag. Paragraph 6.3 describes utilities available to the
user. Paragraphs 6.4 through 6.6 are guides to using each test.
6.2 DIAGNOSTIC MONITOR
The tests described herein are called via a common diagnostic monitor, hereafter called monitor.
This monitor is command-line driven and provides input/output facilities, command parsing,
error reporting, interrupt handling, and a multi-level directory.
6.2.1
Monitor Start-Up
At the CPU32Bug> prompt, enter SD to switch to the diagnostics directory. The Switch
Directories (SD) command is described elsewhere in this chapter. The prompt should now read
CPU32Diag>.
6.2.2
Command Entry and Directories
Enter commands at the CPU32Diag> prompt. The command name is entered before pressing the
carriage return <CR>. Multiple commands may be entered. If a command expects parameters
and another command is to follow it, separate the two with an exclamation point (!). For
instance, to execute the MT B command after the MT A command, the command line would read
MT A ! MT B. Spaces are not required but are shown here for legibility. Several commands may
be combined on one line.
Commands are listed in the diagnostic directory. Some commands have sub-commands which
are listed in the directory for that particular command (see example below).
