Dell T710 owner manual Enables or disables the NMI feature

Option	Description
TPM Activation	When set to Activate, the TPM is enabled to default
(No Change default)	settings. When set to Deactivate, the TPM is disabled.
	The No Change state initiates no action. The operational
	state of the TPM remains unchanged (all user settings for
	the TPM are preserved).
	NOTE: This field is read-only when TPM Security is set to
	Off.
TPM Clear	CAUTION: Clearing the TPM will lose all encryption
(No default)	keys in the TPM. This option prevents booting to the
	operating system and results in data loss if the
	encryption keys cannot be restored. Back up the TPM
	keys prior to enabling this option.
	When set to Yes, all TPM contents are cleared.
	NOTE: This field is read-only when TPM Security is set to
	Off.

	turned off.
	When Disabled, the button can only turn on system
	power.
	NOTE: You can still turn on the system by using the power
	button, even if the Power Button option is set to Disabled.
NMI Button	CAUTION: Use the NMI button only if directed to do
(Disabled default)	so by qualified support personnel or by the operating
	system's documentation. Pressing this button halts
	the operating system and displays a diagnostic
	screen.
