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.

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

	   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.
