NAME

     dpt -- DPT EATA SCSI adapter driver

SYNOPSIS

     dpt* at isa? port ? irq ? dma ?
     dpt* at eisa? slot ?
     dpt* at pci? dev ? function ?
     scsibus* at dpt?

DESCRIPTION

     The dpt driver provides support for third and fourth generation DPT SCSI controllers.  All communication with the controllers is conducted
     via the EATA (Enhanced AT Bus Attachment) protocol.

     DPT adapters examine and interpret all SCSI commands received before passing them to any underlying physical device(s).  In this way,
     caching, RAID and other transformations are achieved while remaining transparent to the host operating system.

HARDWARE

     The dpt driver provides support for the adapters listed below.  Later models are supported by the iop driver.

	   DPT SmartCache III
	   DPT SmartCache IV
	   DPT SmartRAID III
	   DPT SmartRAID IV

FILES

     /dev/dptu	control device for unit u

DIAGNOSTICS

     None of these messages should be encountered under normal circumstances.  It should be noted that the list below is not complete.

     dpt%d: readcfg failed - see dpt(4)
	     The EATA configuration data did not appear upon request.  This may be caused by older firmware.  Generally the solution is to power-
	     cycle the affected machine.

     dpt%d: spurious intr
	     A spurious interrupt was received from the HBA.

     dpt%d: bogus status (returned CCB id NNNN)
	     A corrupt or incomplete status packet was received from the HBA.

     CAM committee standard CAM/89-004 - the EATA (Enhanced AT Bus Attachment) protocol.

HISTORY

     The dpt driver first appeared in NetBSD 1.4.2.

BUGS

     EATA adapters other than listed may function correctly with the dpt driver, however a definitive list is not available.

     Older boards that do not support scatter-gather I/O or DMA are not supported.

     ECC formatted disk and arrays (i.e. with a sector size of 528 bytes) do not work correctly with the PM2041 and certain firmware revisions of
     the PM3334.

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.
