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.
