      dpt - DPT RAID Controller SCSI driver


      For one or more EISA Controllers
      device eisa
      device dpt
      For one or more PCI Controllers
      device pci
      device dpt
      To allow PCI adapters to use memory mapped I/O if enabled:
      options DPT_ALLOW_MEMIO


      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
asr(4) driver.


      The dpt driver provides support for the following RAID adapters:
            DPT Smart Cache Plus
            Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
            Smart RAID II (PM3?2?, PM3021, PM3222)
            Smart Cache III (PM2?3?)
            Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
            Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
            Smart RAID IV

      The dpt driver first appeared in FreeBSD 2.2.6.


      The dpt driver was written by Simon Shapiro and ported to the CAM SCSI
      system by Justin T. Gibbs.
