The PPCBug consists of three parts:
A command-driven, user-interactive software debugger (described
in the PPCBug Firmware Package User's Manual,
PPCBUGA1/UM and PPCBUGA2/UM). It is also referred to as "the
debugger" or "PPCBug".
A command-driven diagnostics package for the MCP750 hardware,
also referred to as the "diagnostics". The diagnostics package is
described in the PPCBug Diagnostics Manual (PPCDIAA/UM).
A user interface or debug/diagnostics monitor that accepts
commands from the system console terminal.
When using the PPCBug, you operate out of either the debugger directory
or the diagnostic directory.
If you are in the debugger directory, the debugger prompt
is displayed and you have all of the debugger commands at
Bug>
your disposal.
If you are in the diagnostic directory, the diagnostic prompt
is displayed and you have all of the diagnostic commands at
Diag>
your disposal as well as all of the debugger commands.
Use the SD command to switch back and forth between these directories.
Because PPCBug is command-driven, it performs its various operations in
response to user commands entered at the keyboard. When you enter a
command, PPCBug executes the command and the prompt reappears.
