NAME

SBusintroduction 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.
