Serial Port A
For each device, Device Available is the default setting and allows the operating system
to access the device. Device Hidden makes the device unavailable; it is disabled by the
BIOS and cannot be enabled by the operating system.
NOTE: An entry for enabling DriveLock appears in the setup menu if the workstation
has a DriveLock-compatible hard disk drive.
USB Security Set workstation USB ports to Enabled/Disabled:
●
Front USB Ports—(1–3)
●
Rear USB Ports—(1–6)
●
Internal USB Ports—(1–6)
Slot Security Lets you enable or disable any PCI or PCI Express slot.
Network Boot Enables or disables the ability to boot to the network using the F12 key or the boot order.
System IDs Provides these options:
●
Asset Tag—A 16-byte string identifying the workstation.
●
Ownership Tag—An 80-byte string identifying ownership of the workstation. This tag
appears on the screen during POST.
●
Universal Unique Identifier (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 workstation.)
●

Master Boot
Record Security
(MBR)
Enable or Disable—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.
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.
System Security Provides these options:
●
Data Execution Prevention—Enables or disables Data Execution Prevention mode
in the CPUs. This mode prohibits code from running in pages that were set up as
data pages, and prevents attacks such as buffer overflows. Operating system
support is required for this feature.
