IBM 6648 Personal Computer User Manual


 
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 6568/6569/6648/6649 has 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 programon page 41.
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 procedureon page 50.
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, riser card, 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 that is 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. The customer has the option to purchase serial number
