SBUS(4) BSD Programmer's Manual SBUS(4)
sbus - introduction to sbus bus support and drivers
sbus* at mainbus? sbus* at iommu? sbus* at xbox?
These sbus attachments are specific to the sparc and sparc64 ports. sbus is an I/O interconnect bus mostly found in SPARC workstations and small to medium server class systems. It supports both on-board peri- pherals and extension boards. The sbus specifications define the bus pro- tocol as well as the electrical and mechanical properties of the exten- sion slots.
OpenBSD includes the following sbus drivers, sorted by device type and driver name:
audioamd(4) AMD 7990 codecs. audiocs(4) Crystal Semiconductor CS4231A codecs.
esp(4) NCR53c94 and compatible SCSI interfaces. isp(4) Qlogic SCSI interfaces.
be(4) "Big Mac" Ethernet board. hme(4) "Happy Meal" Ethernet interfaces. le(4) Lance 7990 series Ethernet interfaces. lebuffer(4), ledma(4) Lance 7990 series Ethernet DMA interfaces. qe(4) Quad Ethernet Controller board.
stp(4) sbus pcmcia(4) bridge.
agten(4) Fujitsu AG-10e accelerated 24-bit color frame buffer. bwtwo(4) Monochromatic frame buffer. cgfourteen(4) Accelerated 8/24-bit color frame buffer. cgsix(4) Accelerated 8-bit color frame buffer. cgthree(4) 8-bit color frame buffer. cgtwelve(4) Accelerated 24-bit color frame buffer. mgx(4) SMS MGX and MGXPlus accelerated 24-bit color frame buffers. pninek(4) Weitek Power9000 frame buffer found on Tadpole SPARCbook 3. pnozz(4) Weitek Power9100 frame buffer found on Tadpole SPARCbook 3GS, 3GX, 3TX and 3XP. rfx(4) Vitec/Connectware/AP&D RasterFlex framebuffer series. tcx(4) Accelerated 8/24-bit color frame buffer. tvtwo(4) Accelerated 24-bit color frame buffer. vigra(4) 8-bit SBus color frame buffer with VGA-compatible modes. zx(4) Accelerated 24-bit color frame buffer.
apio(4) Aurora Technologies pio1 parallel port card. asio(4) Aurora Technologies pio2 serial port card. bpp(4) Parallel port. magma(4) Magma LC series Serial/Parallel Interface cards. spif(4) Sun Serial/Parallel Interface card.
auxio(4) Miscellaneous I/O controls. presto(4) Prestoserve battery-backed memory. uperf(4) Performance counters on the host bridge.
