 27.Dt DPT 4
 28.Os
 29.Sh NAME
 30.Nm dpt
 31.Nd DPT RAID Controller SCSI driver
 32.Sh SYNOPSIS
 33To compile this driver into the kernel,
 34place the following lines in your
 35kernel configuration file:
 36.Bd -ragged -offset indent
 37.Cd "device scbus"
 38.Cd "device dpt"
 39.Pp
 40For one or more EISA cards:
 41.Cd "device eisa"
 42.Pp
 43For one or more ISA cards:
 44.Cd "device isa"
 45.Pp
 46For one or more PCI cards:
 47.Cd "device pci"
 48.Pp
 49To allow PCI adapters to use memory mapped I/O if enabled:
 50.Cd options DPT_ALLOW_MEMIO
 51.Ed
 52.Pp
 53Alternatively, to load the driver as a
 54module at boot time, place the following line in
 55.Xr loader.conf 5 :
 56.Bd -literal -offset indent
 57dpt_load="YES"
 58.Ed
 59.Sh DESCRIPTION
 60The
 61.Nm
 62driver supports DPT RAID SCSI controllers.
 63.Pp
 64SmartRAID (PM3???) are "Enterprise" class cards,
 65and SmartCache (PM2???) cards are in the "Workstation" class.
 66The Gen 4 Smart Cache IV products were a re-issue of the Gen 3 utilizing
 67upgraded (and cheaper to produce) silicon.
 68The PM3334 (Smart RAID III) was not revamped as there was no upgraded silicon
 69(68040 processor) and it was using the best DPT made.
 70Note there has been customer confusion over the faster enterprise class card
 71supported by this driver being an older generation.
 72The Gen5 cards are supported by the
 73.Xr asr 4
 74driver.
 75.Sh HARDWARE
 76The
 77.Nm
 78driver provides support for the following RAID adapters:
