Zusammenfassung:A method of correcting identification data stored in an EEPROM is described. Identification data stored in an EEPROM of a device such as a NIC is programmed into a flash ROM in which the host computer's BIOS is stored. During boot up of the host computer, the BIOS checksums the identification data stored in the EEPROM to determine whether it is valid. If the identification data is determined to be invalid, the EEPROM is reprogrammed with the identification data stored in the flash ROM. Optionally, a flag is set in a CMOS RAM for use by a network administrator to monitor the health of the EEPROM.
