HP ProtectTools Security
Manager—Warning
received: The security
application can not be
installed until the HP
Protect Tools Security
Manager is installed. All security applications such as
Embedded Security, Java Card, and
biometrics are extendable plug-ins for
the HP Security Manager interface.
Security Manager must be installed
before an HP-approved security plug-in
can be loaded. HP ProtectTools Security Manager software must be
installed before installing any security plug-in.
HP ProtectTools TPM
Firmware Update Utility
for dc7600 and models
containing Broadcom-
enabled TPMs—The tool
provided through HP
support Web site reports
ownership required. This is the expected behavior of TPM
firmware utility for dc7600 and models
containing Broadcom-enabled TPMs
The firmware upgrade tool allows the
user to upgrade the firmware, with or
without an endorsement key (EK). 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.

HP ProtectTools Security
Manager—Intermittently,
an error is returned when
closing the Security
Manager interface. Intermittently (1 in 12 instances), an error
is created by using the close button in the
upper right of the screen to close
Security Manager before all plug-in
applications have finished loading. This is related to a timing dependency on plug-in
services load time when closing and restarting Security
Manager. Since PTHOST.exe is the shell housing the
other applications (plug-ins), it depends on the ability of
the plug-in to complete its load time (services). Closing
the shell before the plug-in has had time to complete
loading is the root cause.
