Updating or Rolling Back Devices That Affect Trusted Platform Module Settings

Enabling Trusted Platform Module (TPM) with pre-boot measurement enables the BitLocker protection on the system.

When BitLocker protection is enabled, updating or rolling back the components such as RAID controller, NIC, and BIOS

require that a recovery password is entered or a USB flash drive that contains a recovery key is inserted during the next

system boot. For information on how to set TPM settings, see the

BIOS User Guide

available at support.dell.com/

manuals.

When Lifecycle Controller detects that TPM security is set to On with Pre-boot Measurements, a warning message

displays indicating that certain updates require the recovery password or USB flash drive with the recovery key. The

warning message also indicate components that affect the BitLocker.

You can choose not to update or to roll back those components by navigating to the Select Updates page and

deselecting the check boxes for the components.
