Entering the UEFI Boot Manager
NOTE:
Operating systems must be 64-bit UEFI-compatible (for example, Microsoft
®
Windows Server
®
2008 x64 version) to be installed from the UEFI boot mode. DOS
and 32-bit operating systems can only be installed from the BIOS boot mode.
NOTE:
The Boot Mode must be set to UEFI in the System Setup program to access
the UEFI Boot Manager.
Power Button
(Enabled default) If Enabled, the power button can turn the system's power
off and on. On an ACPI-compliant operating system, the
system performs an orderly shutdown before power is
turned off.
When Disabled, the button can only turn on system
power.
NMI Button
(Disabled default)
CAUTION:
Clearing the TPM will lose all encryption
keys in the TPM. This option prevents booting to the
operating system and results in data loss if the
encryption keys cannot be restored. Back up the
TPM keys prior to enabling this option.
Enables or disables the NMI feature.
AC Power Recovery
(Last default) Determines how the system reacts when power is
restored. If set to Last, the system returns to the last
power state. On turns on the system after power is
restored. Off allows the system to remain off after power
is restored.
AC Power Recovery Delay
(Immediate default)
Determines when the system restarts after power is
restored. Options are Immediate, Random (between
30 to 240 seconds), or a user-defined value of 30 to
240 seconds.
