SBUS(4)                 NetBSD Kernel Interfaces Manual                SBUS(4)

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 peripher-
     als and extension boards. The SBus specifications define the bus protocol
     as well as the electrical and mechanical properties of the extension
     slots.

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

   SCSI interfaces
           esp       NCR53c94 and compatible SCSI interfaces.

           isp       Qlogic SCSI interfaces.

   Network interfaces
           le        Lance 7990 series Ethernet interfaces.

           hme       ``Happy Meal'' Ethernet interfaces.

           en        Midway-based Efficient Networks Inc. and Adaptec ATM
                     interfaces.

           be        ``Big Mac'' Ethernet board.

           qe        Quad Ethernet Controller board.

   Bridges
           xbox      an Sbus expansion box.
