System
Password
This field lets you set, change, or delete the system password (previously called the "Primary" password).
Internal HDD PW
This field lets you set, change, or delete the password on the system's internal hard disk drive (HDD). Successful changes take place
immediately and require a system restart. The HDD password travels with the hard drive, so the HDD is protected even when installed in
another system.
Secondary HDD
PW
This field lets you set, change, or delete the password on the system's second internal hard disk drive (HDD). Successful changes take
place immediately and require a system restart. The HDD password travels with the hard drive, so the HDD is protected even when
installed in another system.
Password Bypass
This option lets you bypass the system and internal HDD password prompts during a system restart or when resuming from a standby
state. Settings are
Disabled , Reboot Bypass , Resume Bypass , and Reboot & Resume Bypass .
The system will always prompt for the set system and internal HDD password when powered on from an off state (cold boot).
Password
Change This option lets you determine whether changes to the System and HDD passwords are permitted when an Admin password is set. Use
the check box to allow or disallow changes.
TPM Security
This option lets you control whether the Trusted Platform Module (TPM) in the system is enabled and visible to the operating system.
When disabled (check box is empty), the BIOS will not turn on the TPM during POST. The TPM will be non-functional and invisible to the
operating system. When enabled (check box filled) the BIOS will turn the TPM on during POST so the it can be used by the operating
system.
NOTE : Disabling this option does not change any settings you may have made to the TPM, nor does it delete or change any
information or keys you may have stored there. It simply turns off the TPM so that it cannot be used. When you re-enable the TPM, it will
function exactly as it did before it was disabled.
Once TPM is enabled (check box filled), the available settings are: Deactivate , Activate , and Clear .
With the TPM in Deactivate mode it will not execute any commands that use the resources of the TPM, nor will it allow any access to
stored owner information.
The Clear setting allows the owner information stored in the TPM to be cleared. Use this to restore the TPM to its default state if you lose
or forget the owner authentication data.
Computrace ®

Disable , and Activate .
The Activate and Disable options will permanently activate or disable the feature and no further changes will be allowed.
