-.Sh NAME
-.Nm trm
-.Nd Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver
-.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 trm"
-.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
-trm_load="YES"
-.Ed
-.Sh DEPRECATION NOTICE
-This driver is scheduled for removal prior to the release of
-.Fx 13.0
-.Sh DESCRIPTION
-The
-.Nm
-driver supports PCI SCSI host adapters based on the Tekram TRM-S1040 SCSI ASIC.
-.Sh HARDWARE
-SCSI controllers supported by the
-.Nm
-driver include:
-.Pp
-.Bl -bullet -compact
-.It
-.Tn Tekram DC-315
-PCI Ultra SCSI adapter without BIOS and internal SCSI connector
-.It
-.Tn Tekram DC-315U
-PCI Ultra SCSI adapter without BIOS
-.It
-.Tn Tekram DC-395F
-PCI Ultra-Wide SCSI adapter with flash BIOS and 68-pin external SCSI connector
-.It
-.Tn Tekram DC-395U
-PCI Ultra SCSI adapter with flash BIOS
-.It
-.Tn Tekram DC-395UW
-PCI Ultra-Wide SCSI adapter with flash BIOS
-.It
-.Tn Tekram DC-395U2W
-PCI Ultra2-Wide SCSI adapter with flash BIOS
-.El
-.Pp
-For the Tekram DC-310/U and DC-390F/U/UW/U2B/U2W/U3W PCI SCSI host adapters,
-use the
-.Xr sym 4
-driver.
