Administrator password:
The administrator
password is used to restrict access to the
Configuration/Setup Utility program. If the administrator
password is activated, and you do not enter the
administrator password, the configuration can be viewed
but not changed.
Note
Type 6868/6878 have Enhanced Security Mode. If
Enhanced Security mode is enabled and there is no
password given, the computer will act as if Enhanced
Security is disabled.
If Enhanced Security is Enabled and an administrator
password is given, the administrator password must
be entered to use the computer. If the administrator
password is lost or forgotten, the system board in the
computer must be replaced in order to regain access
to the Configuration/Setup Utility program.
Administrator password control
The
Administrator password is set in the Setup Configuration.
Refer to “Setup Utility program” on page 329
Operating system password:
An operating
system password is very similar to a power-on password
and denies access to the computer by an unauthorized
user when the password is activated. The computer is
unusable until the password is entered and recognized by
the computer.
Vital product data
Each computer has a unique vital product data (VPD) code
stored in the nonvolatile memory on the system board.
After you replace the system board, the VPD must be
updated. To update the VPD, see “Flash (BIOS/VPD)
update procedure” on page 342.
Management Information Format (MIF)
Management Information Format (MIF) is a file used to
maintain a list of the system unit serial number along with
all serialized components; for example: system board,
memory, and processor.
At the time of computer manufacture, the EPROM will be
loaded with the serial numbers of the system and all major
components. The customer will have access to the MIF
file via the DMI MIF Browser that is installed with the
preload and is also available on the SSCD provided with
the system.
A company called Retain-a-Group is a central data
warehouse offering serial number data management.
Retain-a-Group acts as a focal point to law enforcement.
