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.
