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.
