SBUS(4)                    BSD Programmer's Manual                     SBUS(4)

NAME

     sbus - introduction to sbus bus support and drivers

SYNOPSIS

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

DESCRIPTION

     These sbus attachments are specific to the sparc and sparc64 ports.

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