NAME #

sbus - introduction to SBus bus support

SYNOPSIS #

sbus* at mainbus? sbus* at xbox?

DESCRIPTION #

These sbus attachments are specific to the sparc64 port.

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.
