26. Verifies the configuration data that is resident in NVRAM,   and 

displays a warning message if the verification failed.

27. Calculates and displays the MPU clock speed, verifies that the MPU 

clock speed matches the configuration data, and displays a warning 
message if the verification fails.

28. Displays the BUS clock speed, verifies that the BUS clock speed 

matches the configuration data, and displays a warning message if 
the verification fails.

29. Probes PCI bus for supported network devices.

30. Probes PCI bus for supported mass storage devices.

31. Initializes the memory/IO addresses for the supported PCI bus 

devices.

32. Executes Self-Test, if so configured. (Default is no Self-Test.)

33. Extinguishes the board fail LED, if there are no self-test failures or 

initialization/configuration errors.

34. Executes the configured boot routine, either ROMboot, Autoboot, 

or Network Autoboot.

35. Executes the user interface (i.e., displays the 

PPC1-Bug>

 or

PPC1-Diag>

 

prompt).

PPCBug is command-driven; it performs its various operations in response 
to commands that you enter at the keyboard. When the 

PPC1-Bug

 prompt 

appears on the screen, the debugger is ready to accept debugger 
commands. When the 

PPC1-Diag

 prompt appears on the screen, the 

debugger is ready to accept diagnostic commands. To switch from one 
mode to the other, enter SD.
