firmware Utility
The firmware upgrade tool
allows the user to upgrade
the firmware, both when
there is and when there is not
an endorsement key (EK)
present. When there is no EK,
no authorization is required
to complete the firmware
upgrade.
When there is an EK, a TPM
owner must exist, since the
upgrade requires owner
authorization. After the
successful upgrade, the
platform must be restarted for
the new firmware to take
effect.
If the BIOS TPM is
factory-reset, ownership is
removed and firmware
update capability is
prevented until the Embedded
Security Software platform
and User Initialization
Wizard have been
configured.
*A reboot is always
recommended after
performing a firmware
update. The firmware version
is not identified correctly until
after the reboot.
