Firmware Checkpoints - IBM pSeries 690 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 374.
If you have a checkpoint with no location code associated with it, see "Determining Location Code" on
page 417. If a checkpoint has a location code associated with a FRU replacement, see "AIX and Physical
Location Code Reference Tables" on page 71 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 320 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 following table,
go to "MAP 1542: I/O Problem Isolation" on page 320.
