Clearing Chassis Intrusion Alerts

The system features a chassis intrusion switch which is able to detect any time the base cover has been removed from the
system.
Alerts to notify you of any intrusions can be enabled via the Chassis Intrusion field in the Security sub-menu of the BIOS
setup menu.
When enabled, the Block Boot Until Cleared field allows you to choose whether to prevent normal boot up of the system until
the intrusion alert is cleared.
● If Block Boot Until Cleared is set to ON, the user must select BIOS-Setup and clear the intrusion alert in order to boot up
normally.
