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 periph- erals and extension boards. The SBus specifications define the bus pro- tocol as well as the electrical and mechanical properties of the exten- sion 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. 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
