IBM 6648 Personal Computer User Manual


 
Note: Types 6058/6059/6269/6578/6579 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 program on page 122.
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 130.
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
information and services from Retain-a-Group. It is the customers
responsibility to maintain the MIF file and to inform Retain-a-Group of any
changes to the file.
Some customers may request their servicers to assist them in maintaining the
MIF file when serialized components are replaced during hardware service.
This assistance is between the customer and the servicer. The servicer can use
the DMI MIF Browser to update the MIF information in the EPROM. It is
anticipated that some servicers might charge for this service.
