TPM Functionality 
Enabling TPM Functionality enables the TPM and BIOS secure startup. The TPM is fully functional in this 
mode. 
 
 
CAUTION:  When a TPM is installed and enabled on the server, data access is locked if you 
fail to follow the proper procedures for updating the system or option firmware, replacing the 
system board, replacing a hard drive, or modifying OS application TPM settings. 
 
For information on installing and enabling the TPM module option, see the HP Trusted Platform Module 
Option Installation Instructions that ships with the option. 
Disabling TPM Functionality disables the BIOS secure startup but still allows the TPM to be visible to the 
operating system. The TPM can respond to most commands in this mode. 
Selecting Disabled may prevent the server from booting to a TPM-aware operating system.  
 
TPM Visibility 
The TPM Visibility option provides the ability to hide the TPM from the operating system. When the TPM is 
hidden, BIOS secure startup is disabled, and the TPM does not respond to any commands from any 
software. 
Hiding the TPM may prevent the server from booting to a TPM-aware operating system.
