power-on password and must be entered to boot or enter the BIOS setup utility. In the BIOS
setup utility, the User has Administrator rights. By default, no password is specified.
Save & Exit Menu
The Save & Exit setup menu includes all available options for exiting, saving, and loading the
BIOS default configuration. As an alternative to this screen, press <F9> to load optimal BIOS
default settings and <F10> to save changes and exit setup.
The Exit setup menu includes the following settings:
• Save Changes and Reset—Any changes made to BIOS settings are stored in NVRAM.
The setup utility then exits and reboots the controller. The <F10> key can also be used to
select this option.
• Discard Changes and Reset—Any changes made to BIOS settings during this session of
the BIOS setup utility are discarded. The setup utility then exits and reboots the controller.
The <Esc> key can also be used to select this option.
• Save Changes—Changes made to BIOS settings during this session are committed to
NVRAM. The setup utility remains active, allowing further changes.
• Discard Changes—Any changes made to BIOS settings during this session of the BIOS
setup utility are discarded. The BIOS setup continues to be active.
• Restore Factory Defaults—This option restores all BIOS settings to the factory default.
This option is useful if the controller exhibits unpredictable behavior due to an incorrect or
inappropriate BIOS setting. Notice that any nondefault settings such as boot order,
passwords, and so on, are also restored to their factory defaults. The <F9> key can also be
used to select this option.
• Save As User Defaults—This option saves a copy of the current BIOS settings as the User
Defaults. This option is useful for preserving custom BIOS setup configurations.
• Restore User Defaults—This option restores all BIOS settings to the user defaults. This
option is useful for restoring previously preserved custom BIOS setup configurations.
• Boot Override—This option lists all possible bootable devices and allows the user to
override the Boot Option Priorities list for the current boot. If no changes have been made
to the BIOS setup options, the system will continue booting to the selected device without
first rebooting. If BIOS setup options have been changed and saved, a reboot will be
required and the boot override selection will not be valid.
