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 drive that contains a recovery key is inserted during the next system restart. For information on how to set TPM
settings, see the
BIOS User Guide
available at
www.dell.com/support/home
.
When Lifecycle Controller detects that TPM security is set to
On with Pre-boot Measurements
, a message indicates that certain
updates require the recovery password or USB drive with the recovery key. The message also indicates components that affect the
BitLocker.
You can choose not to update or roll back those components by navigating to the
Select Updates
page, and then clearing the options for
the appropriate components.
