SBUS(4)                      Device Drivers 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
     peripherals and extension boards.  The SBus specifications define the bus
     protocol as well as the electrical and mechanical properties of the
     extension slots.
