HP E3S36UT#ABA, E3S33UT#ABA Slot Security, Network Service Boot, System IDs, Master Boot Record

Table 3-4Computer Setup—Security (continued)

Slot Security	Allows you to disable any PCI or PCI Express slot. Default is enabled.
Network Service 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	Allows you to enable or disable the Master Boot Record (MBR) security. Default is disabled.
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.
	● Save Master Boot Record – This option will appear if Master Boot Record Security is
	enabled. It allows you to save a copy of the Master Boot Record into non-volatile storage.
	● Restore Master Boot Record – This option will appear on the next boot once the Master Boot
	Record has been saved. It allows you to restore the saved copy back to the hard drive’s
	Master Boot Record.
	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.
