These


SBus attachments are specific to the NetBSD/sparc and NetBSD/sparc64 ports.

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.

NetBSD includes machine-independent SBus drivers, sorted by device type and driver name:
