  • Method and apparatus for controlling initiation of bootstrap loading of an operating system in a computer system having first and second discrete computing zones
    Patent number: 5068780
    Abstract: Method and apparatus for controlling initiating of bootstrap loading in a computer system having first and second discrete computing zones is disclosed. Each computing zone includes a status register for storing an operating system run (OSR) bit indicating that the zone has initiated bootstrap loading. A cable connects the computing zones to allow the first and second zones to read the status registers in the second and first zones, respectively. A CPU in each zone only enables initiation of bootstrap loading if the OSR bit in the other zone is not set.
