Description
CAUTION:
Clearing the TPM loses 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.
When set to Yes, all TPM contents are cleared.
NOTE:
This field is read-only when TPM Security
is set to Off.
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.
CAUTION:
Use the NMI button only if directed to
do so by qualified support personnel or by the
operating system's documentation. Pressing this
button halts the operating system and displays a
diagnostic screen.
Enables or disables the NMI feature.

restored. If set to Last, the system returns to the last

restored. Off allows the system to remain off after power
is restored.

restored. Options are Immediate (no delay),
Random (between 30 to 240 seconds for iDRAC,
or 45 to 240 seconds for BMC), or User Defined.
