1    /ALL

    Displays exception data for all CPUs. By default, the registers
    (on Alpha) or exception frame contents (on Integrity servers) are
    omitted from the display for any CPUs with CPUEXIT or DBGCPUEXIT
    bugchecks.

2    /CPU

       /CPU=n

    Allows exception data to be displayed from CPUs other than the
    one considered as the crash CPU when more than one CPU crashes
    simultaneously.
