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:
- esp(4)
- NCR53c94 and compatible SCSI interfaces.
- isp(4)
- Qlogic SCSI interfaces.
- le(4)
- Lance 7990 series Ethernet interfaces.
- hme(4)
- “Happy Meal” Ethernet interfaces.
- be(4)
- “Big Mac” Ethernet board.
- qe(4)
- Quad Ethernet Controller board.
- magma(4)
- Magma Serial/Parallel combo device.
The machine-independent SBus
subsystem appeared in
NetBSD 1.3.
