Boot Steps
Shows the Power-On Self-Test (POST) codes during the system start-up. The POST code is
provided by the BIOS and is displayed on the LCD panel as soon as it is available. If the
system stops during the start-up, the last successful boot step POST code is displayed on
the LCD. When Boot Steps is selected, the POST step will be shown on the LCD status
panel during the subsequent boot processes.
To ensure that MaxiLife is ready to display the first POST codes as soon as possible, the
Pre-boot diagnostics are not executed when the system is booted with the Boot Steps
option selected.
The following diagram shows how Boot Steps obtains its information from the BIOS, and
then displays a POST error if needed.
