SBUS(4) OpenBSD Programmer's Manual SBUS(4)NAME
sbus - introduction to SBus bus support
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
peripherals and extension boards. The sbus specifications define the bus
protocol as well as the electrical and mechanical properties of the
extension slots.
OpenBSD provides support for the following devices. Note that not all
architectures support all devices.
