NAME
SBus
- introduction 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.
