30. Verify the configuration data that is resident in NVRAM,
and display a warning message if the verification failed.
31. Calculate and display the MPU clock speed. Verify that the
MPU clock speed matches the configuration data, and
display a warning message if the verification fails.
32. Display the BUS clock speed. Verify that the BUS clock speed
matches the configuration data, and display a warning
message if the verification fails.
33. For boards that have a Keyboard Controller display
initialization errors that have occurred.
34. Probe PCI bus for supported Network devices.
35. Probe PCI bus for supported Mass Storage devices.
36. Initialize the memory/IO addresses for the supported PCI
bus devices.
37. Execute self-test, if configured.
38. Extinguish the board fail LED, if there are no self-test failures
or initialization/configuration errors.
39. Execute the configured boot routine, either ROMboot,
Autoboot, or Network Autoboot. (PowerPlus architecture
boards do not execute a conÞgured boot routine.)
40. Execute the user interface (i.e., the PPC1-Bug> or
PPC1-Diag> prompt).
LED/Serial Startup Diagnostic Codes
These codes are displayed on seven-segment LEDs at key points in
the initialization of the hardware devices. Should the debugger fail
to come up to a prompt, the last code displayed will indicate how
far the initialization sequence had progressed before stalling. The
serial port version of the startup codes is enabled by an ENV
parameter:
Serial Startup Code Master Enable [Y/N]=N?
