System initialization functions
The following initializations and functions reside in random access memory
(RAM).
Operating system initialization
The operating system defines the configuration table, provides procedures for
handling processor exceptions and invokes the start-up procedure.
Application software initialization
The applications software consists of a number of interdependent processes
and data structures. This function activates the processes, creates interprocess
communication paths and initializes the contents of the data structures.
IPE initialization
When turning on the power for the IPE, the controller card enters a power-up
diagnostic mode and a series of self tests are executed. Test results appear on
the hexadecimal display (see the “Display functions" section).
The first two tests are considered essential for controller card operation.
Failure to execute either of these tests causes a restart of the power-up
diagnostics. After successful completion of the first two tests, the remaining
diagnostic tests are executed.
