VPD must be updated. To update the VPD, see “Flash update procedures” on page

516.

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 is 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 might request that their servicers 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.
