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.
