Clearing chassis intrusion alert

The computer 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 through the Chassis Intrusion option in the Security menu of the
BIOS setup.
When the Chassis Intrusion option is enabled, the Block Boot Until Cleared option allows you to choose whether to prevent
normal boot up of the computer until the intrusion alert is cleared.
If Block Boot Until Cleared option is set to OFF, select Continue to boot up normally or BIOS-Setup to clear the alert.
NOTE: If the Continue option is selected, you will continue to see the alert each time the computer is powered on until the
alert is cleared.
