Note:
Type 6029 computers 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 24.
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 update procedures” on page
265.
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.
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 customer’s 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.
To update the EPROM using the DMI MIF Browser, use the following procedure.
