Table 31. System setup options-Security menu (continued) Security Physical Presence Interface (PPI) Bypass for Clear Commands The PPI Bypass for Clear Commands option allows the operating system to manage certain aspects of PTT. When enabled, you are not prompted to confirm changes to the PTT configuration. By default, the PPI Bypass for Clear Commands option is disabled. For additional security, Dell Technologies recommends keeping the PPI Bypass for Clear Commands option disabled. Clear When enabled, the Clear option clears the information that is stored in the PTT fTPM after exiting the computer's BIOS. 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 PTT 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. By default, the Block Boot Until Cleared option is enabled. NOTE: When enabled, the computer does not boot until the chassis intrusion is cleared. If the administrator password is set, Setup has to be unlocked before the warning can be cleared. OROM Keyboard Access The OROM Keyboard Access feature allows you to enter the Option ROM configuration screens using hotkeys during the boot process. This setting controls only the Intel RAID (CTRL+I), MEBX (CTRL+P), and LSI RAID (CTRL+C) Option ROMs. Other preboot Option ROMs which support entry via a key sequence are not affected by this setting. For additional security, Dell Technologies recommends keeping the OROM Keyboard Access option enabled. Legacy Manageability Interface Access Allows the administrator to control the access to BIOS configuration through the Legacy Manageability Interface option. When enabled, this prevents the BIOS Administrator password-based manageability tools from running, prevents some Dell software applications from reading configuration settings, and/or prevents changes to the BIOS configuration settings. When enabled, this option only supports the Authenticated BIOS Manageability Interface (ABI) for managing the BIOS configuration changes. To support this feature, ABI must be enabled and provisioned. When set to Enabled, the Legacy Manageability Interface can be used to read and change BIOS configuration settings. When set to Read-Only, BIOS configuration settings can be read, but cannot be changed through the Legacy Manageability Interface. 86 BIOS Setup
