3.5 POST Progress and Error Reporting
While POST is initialized, POST progress indications are visible when a TTY-type
terminal or a
tip
line is connected between serial port A (default port) of the system
being tested and a POST monitoring system.
If an error occurs during execution, POST attempts to send a failure message to the
POST monitoring system.
CODE EXAMPLE 3-3
identifies the typical appearance of a
failure message.
Note –
The system does not automatically boot if a POST error occurs; it halts at the
ok
prompt to alert the user of a failure.
