MAINBUS(4)          NetBSD/mac68k Kernel Interfaces Manual          MAINBUS(4)


NAME

     mainbus -- Mac68k main processor bus device


SYNOPSIS

     mainbus0 at root


DESCRIPTION

     The mainbus interface serves as an abstraction used by the autoconfigura-
     tion system to help find and attach busses (e.g. the NuBus expansion bus)
     or devices (e.g. the math coprocessor) connected to the Macintosh main
     processor bus.


DIAGNOSTICS

     mainbus0 (root).  This is the normal autoconfiguration message indicating
     that the main processor bus has been found.
