=== Advanced ===
The section provides advanced system features and functionality settings.<br>
<span style="color:#FF0000">Warning: For advanced users only. Setting items in this section to incorrect values may cause system to malfunction.</span>
==== PCI Settings ====
** Last State - based on system state before the failure it will be either On or Off
** Disable - the feature is disabled
* '''APU TDP''': Set processor maximum power consumption (thermal design power). Enter values between 1-25000 [mW], when default value is 4500 [mW]. Higher value means better performance, and hence that may result in higher temperature.
==== TPM Settings ====
Note: TPM module is not assembled by default. The option relevant in high volume orders.<br>
Trusted platform module settings:
* '''Security Device Support''': Enables or Disables BIOS support for security device. OS will not show security device. TCG EFI protocol and INT1A interface will not be available.
