Security
Chassis Intrusion Enables or disables the detection of chassis intrusion events. This feature notifies
the user when the base cover has been removed from the computer.
When set to Enabled, a notification is displayed on the next boot and the event
is logged in the BIOS Events log.
When set to Disabled, no notification is displayed and no event is logged in the
BIOS Events log.
When set to On-Silent, the event is logged in the BIOS Events log, but no
notification is displayed.
By default, the Chassis Intrusion Detection option is disabled.
For additional security, Dell Technologies recommends keeping the Chassis
Intrusion option enabled.
NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
Block Boot Until Cleared The Block Boot Until Clear option is enabled when Chassis Intrusion is
enabled. When enabled, the computer does not boot until the chassis intrusion is
cleared.
NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
Data Wipe on Next Boot
Start Data Wipe Data Wipe is a secure wipe operation that deletes information from a storage
device.
WARNING: The Secure Data Wipe operation deletes information in a
way that it cannot be reconstructed.
Commands such as delete and format in the operating system may remove files
from showing up in the file system. However, they can be reconstructed through
forensic means as they are still represented on the physical media. Data Wipe
prevents this reconstruction and the data can no longer be recovered.
When enabled, the data wipe option provides prompts to wipe any storage
devices that are connected to the computer on the next boot.
By default, the Start Data Wipe option is disabled.
NOTE: To view this option, enable Advanced Setup mode as described in
View Advanced Setup options.
Absolute Absolute Software provides various cyber security solutions, some requiring
software preloaded on Dell computers and integrated into the BIOS. To use
these features, you must enable the Absolute BIOS setting and contact Absolute
forconfiguration and activation.
By default, the Absolute option is enabled.
For additional security, Dell Technologies recommends keeping the Absolute
option enabled.
WARNING: The Permanently Disabled option can only be selected
once. When Permanently Disabled is selected, Absolute Persistence
cannot be reenabled. No further changes to the Enable/Disable states
are allowed.
NOTE: The Enable/Disable options are unavailable while the computer is in
the activated state.
NOTE: When the Absolute features are activated, the Absolute integration
cannot be disabled from the BIOS Setup screen.
