BootDiagnosticLevel

Syntax

BootDiagnosticLevel = level

Access

Read/Write

Type

Integer

Default

2

Allowed Values

0 | 1 | 2 | 3

Example

BootDiagnosticLevel = 2

Description

Specifies the level of diagnostics during initialization of the board.

This value takes precedence over the corresponding value of the BootDiagnosticLevel keyword set in the system configuration file.

The valid values for level are 0, 1, 2, and 3. Zero (0) indicates that no diagnostics are performed, and 3 is the maximum level. The trade-off for higher levels of diagnostics is the increased time needed to initialize each AG board at load time.

If a test fails, the test number is reported back as the error code.

Note: Some tests can pass back more than one error code, depending on the options selected and/or the mode of failure. These error codes are described in the following table.

Certain tests try to report additional information.

The following tests are performed during the boot diagnostics:
