NAME

     spi -- introduction to machine-independent SPI bus support and drivers

SYNOPSIS

     spi* at mainbus?

     Other attachments are machine-dependent and will depend on the bus topology of your system.  See intro(4) for your system for more informa-
     tion.

DESCRIPTION

     NetBSD includes a machine dependent SPI (Serial Peripheral Interface) bus subsystem, and several different machine-independent SPI device
     drivers.

     Your system may support additional machine-dependent SPI devices.	Consult your system's intro(4) for additional information.

     SPI is a 4-wire synchronous full-duplex serial bus.  Some systems provide support for Microwire, which is Philips' name for a strict subset
     of SPI, with more rigidly defined signaling.  Therefore, Microwire devices are also supported by the SPI framework.

     Note that when referencing SPI devices in a config(1) file, the 'slave' must be provided, as SPI lacks any way to automatically probe
     devices.

HARDWARE

     NetBSD includes the following machine-independent SPI drivers

	   m25p       STMicroelectronics M25P family of NOR flash devices.

	   tm121temp  Texas Instruments TMP121 temperature sensor.

SEE ALSO

     m25p(4), tm121temp(4)

HISTORY

     The machine-independent SPI framework was written by Garrett D'Amore for the Champaign-Urbana Community Wireless Network Project (CUWiN), and
     appeared in NetBSD 4.0.

NAME

     eisa -- Introduction to EISA bus machine-independent drivers and support

SYNOPSIS

     options EISAVERBOSE

     Machine-dependent; depends on the bus topology and EISA bus interface of your system.  Typical EISA buses are either connected directly to
     the main system bus, or via an PCI to EISA bridge.  See the intro(4) documentation for your system for details.

DESCRIPTION

     NetBSD includes a machine-independent EISA bus subsystem and several machine-independent EISA device drivers.

     Your system may support additional EISA devices.  Drivers for EISA devices not listed here are machine-dependent.	Consult your system's
     intro(4) for additional information.

SUPPORTED DEVICES

     NetBSD includes machine-independent EISA drivers, sorted by device type and driver name:

   Disk and tape controllers
	   cac	      Compaq array controllers.

	   mlx	      Mylex DAC960 and DEC SWXCR RAID controllers.

   SCSI interfaces
	   ahb	      Adaptec 174x SCSI interfaces.

	   ahc	      Adaptec AIC 7770, 274x, and 284x SCSI interfaces.

	   bha	      BusLogic BT-74x SCSI interfaces.

	   dpt	      DPT SmartCache/SmartRAID III and IV SCSI interfaces.

	   uha	      Ultrastor 24f SCSI interfaces.

   Network interfaces
	   ep	      3Com 3c579 and 3c592 10Mbit Ethernet, and 3c597 10/100Mbit Ethernet interfaces.

	   fea	      Digital DEFEA FDDI interfaces.

	   le	      Digital DE422 Ethernet interfaces.

	   tlp	      Digital DE425 Ethernet interfaces.

     Note that most or all EISA devices also have PCI or ISA equivalents.  These are listed in pci(4), isa(4), or isapnp(4), respectively.  The
     manual pages for each individual driver also lists the supported bus variants.
