Important
PC 700 Series Only:
If the Administrator Password is lost or forgotten, the
password cannot be changed or removed. If this
occurs, the system board must be replaced and the
customer charged accordingly.
PC 300 Series and IntelliStation:
The Administrator Password can be reset on PC 300
Series and IntelliStation computers.
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 201.
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. MIF is used on Type:
Ÿ
6561, 6591
Ÿ
6562, 6592,
Ÿ
6862, 6892,
Ÿ
6889
At the time of computer manufacture, the EPROM (located
on the riser card) 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
RTC CD 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
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
