NAME

       dpt - DPT ServeRAID IV SCSI host bus adapter and RAID adapter driver

DESCRIPTION

       The dpt driver is a driver for the DPT (Distributed Processing Technology) family of SmartRAID IV SCSI HBA and RAID adapters. The following
       HBA adapters are supported: PM2024, PM2044UW, PM2044W, PM2124, PM2124W, PM2144UW, and PM2144W.

       The following RAID adapters are supported: PM3224, PM3224W, PM3334UW, and PM3334W.

PRECONFIGURATION

	 o  DPT PM3224 only: Only EPROM 7A and later versions are supported.

	 o  DPT PM2024 and PM2124 only: Only EPROM 6D4 and later versions are supported.

	 o  Use adapters with SmartROM version 3.B or later versions only.

	 o  Be sure that the controller board is installed in a PCI bus-mastering slot.

	 o  Disable PCI parity checking if your firmware version is earlier than version 7A, if your system memory is ECC, or if your system  does
	    not check parity.

   Known Problems and Limitations
       During  system boot, a message may be displayed saying a DPT controller driver cannot be installed. This message indicates that the mother-
       board installed in your system may contain ECC memory or may not check parity. If you see this message is  displayed,  disable  PCI  parity
       checking.

   Supported Settings
	 o  I/O Address: Auto

CONFIGURATION

       Auto-configuration  code  determines whether the adapter is present at the configured address and what types of devices are attached to it.
       The DPT ServeRAID is primarily used as a disk array (system drive) controller.

       To configure the attached disk arrays, you must configure the controller (using the configuration utilities provided by the hardware  manu-
       facturer)  before  you  boot  the Solaris operating environment. You use the configuration utilities to set RAID levels, stripe parameters,
       cache mechanisms and perform other functions. For more information, see the user manual supplied with your hardware.

NAME

     dpt -- DPT RAID Controller SCSI driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device dpt

	   For one or more EISA cards:
	   device eisa

	   For one or more ISA cards:
	   device isa

	   For one or more PCI cards:
	   device pci

	   To allow PCI adapters to use memory mapped I/O if enabled:
	   options DPT_ALLOW_MEMIO

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   dpt_load="YES"

DESCRIPTION

     The dpt driver supports DPT RAID SCSI controllers.

     SmartRAID (PM3???) are "Enterprise" class cards, and SmartCache (PM2???) cards are in the "Workstation" class.  The Gen 4 Smart Cache IV
     products were a re-issue of the Gen 3 utilizing upgraded (and cheaper to produce) silicon.  The PM3334 (Smart RAID III) was not revamped as
     there was no upgraded silicon (68040 processor) and it was using the best DPT made.  Note there has been customer confusion over the faster
     enterprise class card supported by this driver being an older generation.	The Gen5 cards are supported by the asr(4) driver.

HARDWARE

     The dpt driver provides support for the following RAID adapters:

     o	 DPT Smart Cache Plus
     o	 Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
     o	 Smart RAID II (PM3?2?, PM3021, PM3222)
     o	 Smart Cache III (PM2?3?)
     o	 Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
     o	 Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
     o	 Smart RAID IV

HISTORY

     The dpt driver first appeared in FreeBSD 2.2.6.
