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.

HME(4)							   BSD Kernel Interfaces Manual 						    HME(4)

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.

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