Table 12. BIOS Setup options—Security menu(continued)

Security Description

For additional security, Dell Technologies recommends keeping the PPI Bypass

for Clear Command option disabled.

Clear

When enabled, the Clear option clears the information that is stored in the AMD

fTPM after exiting the BIOS setup of your computer. This option returns to the

disabled state when the computer restarts.

By default, the Clear option is disabled.

Dell Technologies recommends enabling the Clear option only when fTPM data

needs to be cleared.

Chassis intrusion

Chassis Intrusion Detection The chassis intrusion detection enables a physical switch that triggers an event

when the computer cover is opened.

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 On-Silent, the event is logged in the BIOS Events log, but no

notification is displayed.

When set to Disabled, no notification is displayed and no event is logged in the

BIOS Events log.

By default, the Chassis Intrusion Detection option is enabled.

For additional security, Dell Technologies recommends keeping the Chassis

Intrusion Detection option enabled.

Block Boot Until Cleared Enables or disables the Block Boot Until Cleared option.

booting after a chassis intrusion event is detected. The warning must be

cleared from BIOS Setup, by clearing the Chassis Intrusion Warning option.

If a BIOS Admin Password is set, the password must be entered prior to

clearing the Chassis Intrusion Warning.

Dell Technologies recommends keeping the Block Boot Until Cleared option

disabled.

intrusion is detected. This setting could cause data loss or corruption.

option disabled.

is detected. This setting could cause data loss or corruption.
