This chapter explains how to determine which hardware or software controls
the system during different phases of system operation.
2.1 System Control
To troubleshoot a problem, determine which part of the system is in control
during the involved phase of operation.
When AC power is applied, system control passes in the order below:
•
Power switch, in rear
•
Key switch, in front
•
Control board
•
Power-on self-test (POST) program
•
OpenBoot program
•
Operating system
Table 2-1 shows the actions that occur as system control progresses from one
phase to the next.
