RS/6000 43P 7043 Models 150 and 260 Handbook

Firmware Checkpoints are intended to let users and service personal know 
what the system is doing, in some detail, as it initializes. These checkpoints 
occur during system start-up and are not intended to be error indicators, but 
in some cases a system could hang at one of the checkpoints. The most 
appropriate action is included with each checkpoint.
