Owners Manual

Option Description
Power Button Enables or disables the power button on the front of the system. This option is set to Enabled by default.
AC Power
Recovery
Sets how the system behaves after AC power is restored to the system. This option is set to Last by
default.
AC Power
Recovery Delay
Sets the time delay for the system to power up after AC power is restored to the system. This option is
set to Immediate by default.
User Defined
Delay (60 s to
240 s)
Sets the User Defined Delay option when the User Defined option for AC Power Recovery Delay is
selected.
UEFI Variable
Access
NOTE: The NX3240 system does not support UEFI mode. This option cannot be used.
Provides varying degrees of securing UEFI variables. When set to Standard (the default), UEFI variables
are accessible in the operating system per the UEFI specification. When set to Controlled, selected UEFI
variables are protected in the environment and new UEFI boot entries are forced to be at the end of the
current boot order.
Secure Boot Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certificates in the
Secure Boot Policy. Secure Boot is set to Disabled by default.
Secure Boot
Policy
When Secure Boot policy is set to Standard, the BIOS uses the system manufacturer’s key and
certificates to authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses
the user-defined key and certificates. Secure Boot policy is set to Standard by default.
Secure Boot
Mode
Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).
If the current mode is set to Deployed Mode, the available options are User Mode and Deployed Mode.
If the current mode is set to User Mode, the available options are User Mode, Audit Mode, and
Deployed Mode.
● User Mode — In User Mode, PK must be installed, and BIOS performs signature verification on
programmatic attempts to update policy objects. The BIOS allows unauthenticated programmatic
transitions between modes.
● Audit Mode — In Audit mode, PK is not present. The BIOS does not authenticate programmatic
updates to the policy objects, and transitions between modes. Audit Mode is useful for
programmatically determining a working set of policy objects. BIOS performs signature verification on
pre-boot images and logs results in the image Execution Information Table, but executes the images
whether they pass or fail verification.
● Deployed Mode — Deployed Mode is the most secure mode. In Deployed Mode, PK must be
installed and the BIOS performs signature verification on programmatic attempts to update policy
objects. Deployed Mode restricts the programmatic mode transitions.
Secure Boot
Policy Summary
Specifies the list of certificates and hashes that secure boot uses to authenticate images.
Secure Boot
Custom Policy
Settings
Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom
option.
Creating a system and setup password
Prerequisites
Ensure that the password jumper is enabled. The password jumper enables or disables the system password and setup password
features. For more information, see the Jumpers and connectors section.
NOTE:
If the password jumper setting is disabled, the existing system password and setup password are deleted and you
need not provide the system password to boot the system.
Steps
1. To enter System Setup, press F2 immediately after turning on or rebooting your system.
2. On the System Setup Main Menu screen, click System BIOS > System Security.
