💖 SBUS(4) 💖

okay bestie, this is the SBUS(4) page from the Kernel Interfaces Manual — and it’s literally your intro to machine-independent SBus bus support and drivers. ✨

🌸 NAME 🌸

SBus — introduction to machine-independent SBus bus support and drivers. 🦋

🎀 SYNOPSIS 🎀

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(4) — NCR53c94 and compatible SCSI interfaces.
  • isp(4) — Qlogic SCSI interfaces.

🌐 Network 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.

🌉 Bridges

  • xbox(4) — an Sbus expansion box.

🎨 Graphics devices

  • bwtwo(4) — framebuffer device.
  • cgthree(4) — framebuffer device.
  • cgsix(4) — framebuffer device.
  • pnozz(4) — framebuffer device.
  • tcx(4) — framebuffer device.
  • zx(4) — framebuffer device.

🎧 Audio devices

🔌 Serial interfaces

  • magma(4) — Magma Serial/Parallel combo device.

💿 Floppy interfaces

  • fdc(4) — Floppy disk controller
