Andrew Grove, chief executive of the world's runaway most successful producer of personal computer chips, Pentium-making Intel Corp., came to Chicago on Friday with a message for the cream of this city's corporate bosses.

Grove, who runs Santa Clara, Calif.-based Intel under a management system he calls "constructive confrontation," acknowledged that taking such a view to one's work--and to the rest of one's life--may not make a person particularly happy.
