  • Appratus for preventing changes of computer configuration data by unauthorized users
    Patent number: 5781793
    Abstract: A protection system for a computer is provided. This system is essentially based on the provision of an EEPROM (20) of unstandard access and containing configuration data of the computer as well as a password. At power-on, the contents of the EEPROM except eventually the password, are copied into a CMOS memory (16) which must conventionally be present in the computer. The invention eventually provides additional circuitry for irreversibly cutting the access to the EEPROM and specified peripheric devices.
    Type: Grant
    Filed: January 30, 1996
    Date of Patent: July 14, 1998
    Assignee: Hewlett-Packard Company
    Inventors: Jean-Fran.cedilla.ois Larvoire, Thierry Ribollet, Bertrand Hays
