HP 402 G1 manual Device Security, USB Security, Slot Security, Network Boot, System IDs

Table 6-4Computer Setup—Security (continued)

Device Security	Allows you to set Device Available/Device Hidden (default is Device Available) for:
	●	Embedded security device
	●	System audio
	●	USB controller (varies by model)
	●	Network controller
		NOTE: You must disable AMT before trying to hide the network controller.
	●	Serial port
	●	Parallel port
	●	SATA ports (varies by model)
USB Security	Allows you to set Enabled/Disabled (default is Enabled) for:
	●	Front USB Ports
	●	Rear USB Ports
	●	Accessory USB Ports
Slot Security	Allows you to disable any PCI or PCI Express slot. Default is enabled.
Network Boot	Enables/disables the computer’s ability to boot from an operating system installed on a network server.
	(Feature available on NIC models only; the network controller must be either a PCI expansion card or
	embedded on the system board.) Default is enabled.
System IDs	Allows you to set:
	●	Asset tag (18-byte identifier), a property identification number assigned by the company to the
		computer.
	●	Ownership tag (80-byte identifier) displayed during POST.
	●	Universal Unique Identifier (UUID) number. The UUID can only be updated if the current chassis
		serial number is invalid. (These ID numbers are normally set in the factory and are used to uniquely
		identify the system.)
	●	Keyboard locale setting for System ID entry.
Master Boot Record	Enables/disables Master Boot Record (MBR) security.
Security	The MBR contains information needed to successfully boot from a disk and to access the data stored on
	the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such
	as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you to
	recover the "last known good" MBR, should changes to the MBR be detected when the system is
	restarted.
	When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current
	bootable disk while in MS-DOS or Windows Safe Mode.
	NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot
	prevent changes that may occur while the operating system is running.
	Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
	Only appears if all of the following conditions are true:
	●	MBR security is enabled
	●	A backup copy of the MBR has been previously saved
	●	The current bootable disk is the same disk from which the backup copy was saved
