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
	   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.

   Graphics devices
	   bwtwo     framebuffer device.

	   cgthree   framebuffer device.

	   cgsix     framebuffer device.

	   pnozz     framebuffer device.

	   tcx	     framebuffer device.

	   zx	     framebuffer device.

   Audio devices
	   audiocs   CS4231 codec.

   Serial interfaces
	   magma     Magma Serial/Parallel combo device.

   Floppy interfaces
	   fdc	     Floppy disk controller

NAME

     hme -- Sun Microelectronics STP2002-STQ Ethernet interfaces device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device miibus
	   device hme

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_hme_load="YES"

DESCRIPTION

     The hme driver supports Sun Microelectronics STP2002-STQ ``Happy Meal Ethernet'' Fast Ethernet interfaces.

     All controllers supported by the hme driver have TCP checksum offload capability for both receive and transmit, support for the reception and
     transmission of extended frames for vlan(4) and a 128-bit multicast hash filter.

HARDWARE

     The hme driver supports the on-board Ethernet interfaces of many Sun UltraSPARC workstation and server models.

     Cards supported by the hme driver include:

     o	 Sun PCI SunSwift Adapter (``SUNW,hme'')
     o	 Sun SBus SunSwift Adapter (``hme'' and ``SUNW,hme'')
     o	 Sun PCI Sun100BaseT Adapter 2.0 (``SUNW,hme'')
     o	 Sun SBus Sun100BaseT 2.0 (``SUNW,hme'')
     o	 Sun PCI Quad FastEthernet Controller (``SUNW,qfe'')
     o	 Sun SBus Quad FastEthernet Controller (``SUNW,qfe'')

NOTES

     On sparc64 the hme driver respects the local-mac-address? system configuration variable which can be set in the Open Firmware boot monitor
     using the setenv command or by eeprom(8).	If set to ``false'' (the default), the hme driver will use the system's default MAC address for
     all of its devices.  If set to ``true'', the unique MAC address of each interface is used if present rather than the system's default MAC
     address.

     Supported interfaces having their own MAC address include on-board versions on boards equipped with more than one Ethernet interface and all
     add-on cards except the single-port SBus versions.

HISTORY

     The hme driver first appeared in NetBSD 1.5.  The first FreeBSD version to include it was FreeBSD 5.0.
