 33.Dt ISP 4
 34.Os
 35.Sh NAME
 36.Nm isp
 37.Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
 38.Sh SYNOPSIS
 39To compile this driver into the kernel,
 40place the following lines in your
 41kernel configuration file:
 42.Bd -ragged -offset indent
 43.Cd "device scbus"
 44.Cd "device isp"
 45.Ed
 46.Pp
 47Alternatively, to load the driver as a
 48module at boot time, place the following line in
 49.Xr loader.conf 5 :
 50.Bd -literal -offset indent
 51isp_load="YES"
 52.Ed
 53.Sh DESCRIPTION
 54This driver provides access to
 55.Tn SCSI
 56or
 57.Tn FibreChannel
 58devices.
 59.Pp
 60SCSI features include support for Ultra SCSI and wide mode transactions
 61for
 62.Tn SCSI ,
 63Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
 64ISP12160).
 65.Pp
 66Fibre Channel support uses FCP SCSI profile for
 67.Tn FibreChannel ,
 68and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
 693 only, minor patches to the Qlogic 2200 to force Class 2 mode).
 70Support is available for Public and Private loops, and for
 71point-to-point connections (Qlogic 2200 only).
 72The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432)
 73are also supported.
 74Command tagging is
 75supported for all (in fact,
 76.Tn FibreChannel
 77requires tagging).
 78Fabric support is enabled by default for other than 2100 cards.
 79Fabric
 80support for 2100 cards has been so problematic and these cards are so
 81old now that it is just not worth your time to try it.
 82.Sh FIRMWARE
 83Firmware is available if the
 84.Xr ispfw 4
 85module is loaded during bootstrap (q.v.).
 86.Pp
 87It is
 88.Ar strongly
 89recommended that you use the firmware available
 90from
 91.Xr ispfw 4
 92as it is the most likely to have been tested with this driver.

 95.Nm

226.Sh AUTHORS
227The
228.Nm
229driver was written by Matthew Jacob originally for NetBSD at
230NASA/Ames Research Center.
231.Sh BUGS
232The driver currently ignores some NVRAM settings.
233.Pp
234Target mode support is not completely reliable yet.
235It works reasonably
236well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
237does not yet work for the other cards (due to last minute unannounced
238changes in firmware interfaces).
