System Initialization and Acceptance Testing (Normal Operation)
4.3 CPU ROM-Based Diagnostics
A program called the
diagnostic executive
determines which of the available
scripts to invoke. The script sequence varies if the system is in the
manufacturing environment. The diagnostic executive interprets the script to
determine what tests to run, the correct order to run the tests, and the correct
parameters to use for each test.
The diagnostic executive also controls tests so that errors can be detected
and reported. It ensures that when the tests are run, the machine is left in a
consistent and well-defined state.
4.3.1 Diagnostic Tests
Example 4–4 shows a list of the ROM-based tests and utilities. To get this
listing, enter T 9E at the console prompt (T is the abbreviation of TEST). The
column headings have the following meanings:
Note
Base addresses shown in this document may not be the same as the
addresses you see when you run T 9E. Run T 9E to get a list of actual
addresses. See Example 4–4.
