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: 6561, 6591 6562, 6592, 6862, 6892, 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 192 IBM PC 300/700, IntelliStation Series HMM
