SBUS(4)                 NetBSD Kernel Interfaces Manual                SBUS(4)


NAME

     SBus -- introduction to machine-independent SBus bus support and drivers


SYNOPSIS

     sbus* at mainbus?
     sbus* at iommu?
     sbus* at xbox?

     These
     SBus attachments are specific to the NetBSD/sparc and NetBSD/sparc64
           ports.


DESCRIPTION

     SBus is a I/O interconnect bus mostly found in SPARC workstations and
     small to medium server class systems.  It supports both on-board periph-
     erals and extension boards.  The SBus specifications define the bus pro-
     tocol as well as the electrical and mechanical properties of the exten-
     sion slots.
