Firmware Checkpoints - IBM eserver p Series Service Manual

Firmware Checkpoints

Firmware uses checkpoints (progress codes) in the range of Exxx 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 189.
If you have a checkpoint with no location code associated with it, see "Determining the Location Code" on
page 243. If a checkpoint has a location code associated with a FRU replacement, see "AIX and Physical
Location Code Reference Tables" on page 32 for physical location information.
If you replace FRUs and the problem is still not corrected, go to "MAP 1542: I/O Problem Isolation" on
page 144 unless otherwise indicated in the tables.
Note: If you receive a four-digit code in the range of E1xx to EFFF that is not listed in the table above, go
to "MAP 1542: I/O Problem Isolation" on page 144.
