MAINBUS(4)           OpenBSD Programmer's Manual (Mac68K)           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.

SEE ALSO
     autoconf(4), obio(4)

HISTORY
     The mainbus first appeared in NetBSD 1.2.

OpenBSD 2.9                      July 2, 1997                                1
