Diagnostic Tests
In order to use the diagnostics, you must switch to the diagnostic directory.
You may switch between directories by using the SD (Switch Directories)
command. You may view a list of the commands in the directory that you
are currently in by using the HE (Help) command.
If you are in the debugger directory, the debugger prompt
PPC1-Bug>
displays, and all of the debugger commands are available. Diagnostics
commands cannot be entered at the
PPC1-Bug>
prompt.
If you are in the diagnostic directory, the diagnostic prompt
PPC1-Diag>
displays, and all of the debugger and diagnostic commands are available.
Note that not all tests are valid for the MCP750. Using the HE command,
you can list the diagnostic routines available in each test group. Refer to
the PPCBug Diagnostics Manual, listed in
Appendix B, Related
