Firmware Checkpoints
Firmware uses progress codes (checkpoints) in the range of E1xx to EFFF. These
checkpoints occur during system startup and can be useful in diagnosing certain
problems. Service processor checkpoints are listed in "Service Processor Checkpoints"
on page 86.
If you replace FRUs or perform an action, and the problem is still unresolved, go to
"MAP 1540: Minimum Configuration" on page 63 unless otherwise indicated in the
tables.
If you replace FRUs or perform an action, and the problem is corrected, go to "MAP
0410: Repair Checkout" in the RS/6000 Eserver pSeries Diagnostic Information for
Multiple Bus Systems .
