		the device. Device Hidden makes the device unavailable; it is disabled by the BIOS and cannot be
		enabled by the operating system.

		DriveLock-compatible hard disk drive.
	Embedded	This option becomes available if Embedded Device is set to Available.
	Security Device	Embedded Security Device (Hidden or Available) turns the Trusted Platform Mechanism (TPM) on
		and off. Device Hidden is the default. If this option is made available, the following options become
		available:
		● Power-On Authentication Support—Enables and disables an authentication feature that
			requires you to enter a TPM user key password to start the workstation. This feature uses the
			TPM to generate and store the authentication password.
		● Reset Authentication Credential—Resets the authentication functionality and clears
			authentication credentials.
		To enable the Embedded Security Device and to access any security features associated with the
		device, you must enter a setup password.
		Setting a device to Available enables the operating system to access the device. Hidden makes
		the device unavailable. It is disabled by the BIOS and cannot be enabled by the operating system.
	Network Service	Enables or disables the ability to boot to the network using the F12 key or the boot order.
