Enable or disable fingerprint
authentication before the operating
system is loaded.
If External ➙ Internal is selected,
an external fingerprint reader is used
if attached. Otherwise, an internal
fingerprint reader is used. If Internal
Only is selected, an internal fingerprint

select Yes.
Note: Intel PTT can be used with the
Windows 8 or later operating system.
If you select Active, the security chip
is functional. If you select Inactive,
