-.Os
-.Sh NAME
-.Nm esp
-.Nd Emulex ESP, NCR 53C9x and QLogic FAS families based SCSI controllers
-.Sh SYNOPSIS
-To compile this driver into the kernel, place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device scbus"
-.Cd "device esp"
-.Ed
-.Pp
-Alternatively, to load the driver as a module at boot time, place the
-following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-if_esp_load="YES"
-.Ed
-.Sh DEPRECATION NOTICE
-The
-.Nm
-driver is not present in
-.Fx 13.0 .
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for the
-.Tn AMD
-Am53C974, the
-.Tn Emulex
-ESP100, ESP100A, ESP200 and ESP406, the
-.Tn NCR
-53C90, 53C94 and 53C96 as well as the
-.Tn QLogic
-FAS100A, FAS216, FAS366 and FAS408
-.Tn SCSI
-controller chips found in a wide variety of systems and peripheral boards.
-.Sh HARDWARE
-Controllers supported by the
-.Nm
-driver include:
-.Pp
-.Bl -bullet -compact
-.It
-Tekram DC390
-.It
-Tekram DC390T
-.El
-.Sh SEE ALSO
-.Xr cd 4 ,
-.Xr ch 4 ,
-.Xr da 4 ,
-.Xr intro 4 ,
-.Xr pci 4 ,
-.Xr sa 4 ,
-.Xr scsi 4 ,
-.Xr camcontrol 8
-.Sh HISTORY
-The
-.Nm
-driver first appeared in
-.Nx 1.3 .
-The first
-.Fx
-version to include it was
-.Fx 5.3 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-driver was ported to
-.Fx
-by
-.An Scott Long Aq Mt scottl@FreeBSD.org
-and later on considerably improved by
-.An Marius Strobl Aq Mt marius@FreeBSD.org .
-.Sh BUGS
-The
-.Nm
-driver should read the EEPROM settings of
-.Tn Tekram
-controllers.
