introduction to machine-independent SBus bus support and
drivers

These
SBus |
attachments are specific to the NetBSD/sparc and
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
- NCR53c94 and compatible SCSI interfaces.
- isp
- Qlogic SCSI interfaces.
- le
- Lance 7990 series Ethernet interfaces.
- hme
- “Happy Meal” Ethernet interfaces.
- be
- “Big Mac” Ethernet board.
- qe
- Quad Ethernet Controller board.
- xbox
- an
Sbus
expansion box.
- bwtwo
- framebuffer device.
- cgthree
- framebuffer device.
- cgsix
- framebuffer device.
- pnozz
- framebuffer device.
- tcx
- framebuffer device.
- zx
- framebuffer device.
- magma
- Magma Serial/Parallel combo device.
- fdc
- Floppy disk controller
