NAME
     isp -- Qlogic based SCSI and FibreChannel SCSI Host Adapters

SYNOPSIS
     device isp

     For one or	more SCSI busses:
     device scbus0

DESCRIPTION
     This driver provides access to SCSI or FibreChannel devices.

     SCSI features include support for Ultra SCSI and wide mode	transactions
     for SCSI, Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD	(for
     the ISP12160).

     Fibre Channel support uses	FCP SCSI profile for FibreChannel.  and	uti-
     lizes Class 3 and Class 2 connections (Qlogic 2100	is Class 3 only, minor
     patches to	the Qlogic 2200	to force Class 2 mode).	 Support is available
     for Public	and Private loops, and for point-to-point connections (Qlogic
     2200 only).  The newer 2-Gigabit cards (2300, 2312) are also supported.
     Command tagging is	supported for all (in fact, FibreChannel requires tag-
     ging).  Fabric support is enabled by default (but may be contingent upon
     the correct firmware being	loaded).

FIRMWARE
     Firmware is now available if the ispfw(4) module is loaded	during boot-
     strap (q.v.).

     It	is very	strongly recommended that you use the firmware available from
     ispfw(4) as it is the most	likely to have been tested with	this driver.

		   single and dual attach).

	   Qlogic 2322
		   Qlogic 2322 Optical Fibre Channel PCI cards.

	   Qlogic 200
		   Dell	Branded	version	of the QLogic 2312 Fibre Channel PCI

CONFIGURATION OPTIONS
     Target mode support may be	enabled	with the

     options ISP_TARGET_MODE

     option.

BOOT OPTIONS
     The following options are switchable by setting values in
     /boot/device.hints.

     They are:

     hint.isp.0.disable
	     A hint value to disable driver in kernel.

     hint.iso.0.fwload_disable
	     A hint value to disable loading of	firmware ispfw(4).

     hint.isp.0.prefer_memmap
	     A hint value to use PCI Memory space instead of I/O space access
	     for.

     hint.isp.0.prefer_iomap
	     A hint value to use PCI I/O space instead of Memory space access
	     for.

     hint.isp.0.ignore_nvram
	     A hint value to ignore board NVRAM	settings for. Otherwise	use
	     NVRAM settings.

     hint.isp.0.fullduplex
	     A hint value to set full duplex mode.

     hint.isp.0.topology
	     A hint value to select topology of	connection. Supported values
	     are:

	     lport (Prefer loopback and	fallback to point to point).

	     nport (Prefer point to point and fallback to loopback).

	     lport-only	(Loopback only).

	     nport-only	(Point to point	only).

     hint.isp.0.portwwn
	     This should be the	full 64	bit World Wide Port Name you would
	     like to use, overriding the value in NVRAM	for the	card.

     hint.isp.0.nodewwn
	     This should be the	full 64	bit World Wide Node Name you would
	     like to use, overriding the value in NVRAM	for the	card.

     hint.isp.0.iid
	     A hint to override	or set the Initiator ID	(principally for SPI
	     SCSI).

     hint.isp.0.role
	     A hint to define default role for isp instance (target, initia-
	     tor, both).

     hint.isp.0.debug
	     A hint value for a	driver debug level (values from	0 through 7).
	     Default is	0.

AUTHORS
     The isp driver was	written	by Matthew Jacob for NASA/Ames Research	Cen-
     ter.

BUGS
     The driver	currently ignores some NVRAM settings.

     The driver	currently does not do error recovery for timed out commands
     very gracefully.

     Target mode support is not	completely debugged yet.  It works reasonably
     well for Fibre Channel, somewhat well for Qlogic 1040 cards, but does not
     yet work for the other cards (due to last minute unannounced changes in
     firmware interfaces).

     Sometimes,	when booting, the driver gets stuck waiting for	the Fibre
     Channel f/w to tell it that the loop port database	is ready, or waiting
     for a good	loop to	be seen	(this does not yet support booting without
     being connected to	a fibre	channel	device).  To unwedge the system,
     unplug and	replug the fibre channel connection, or	otherwise cause	a LIP
     (Loop Initialization Primitive sequence)- this will kick the f/w into
     getting unstuck.

     QLogic 2322 support is limited to platforms where the BIOS	can enable
     firmware as there is no code yet to do the	3 stage	loading	for 2322
     firmware.
