NAME
     adpu320 - Adaptec Ultra320 SCSI host bus adapter driver

SYNOPSIS
     scsi@unit-address


DESCRIPTION
     The adpu320 host bus  adapter  driver  is  a  SCSA-compliant
     nexus  driver  that  supports the following Adaptec Ultra320
     SCSI Devices:

     Chips    AIC-7902



     The adpu320 driver supports standard functions  provided  by
     the  SCSA  interface, including tagged and untagged queuing,
     Wide/Fast/Ultra SCSI, and auto request  sense.  The  adpu320
     driver  does not support linked commands. The adpu320 driver
     supports hot swap SCSI and hot plug PCI.


     Additionally, the  adpu320  driver  supports  the  following
     features:

         o    64-bit addressing (Dual address Cycle)

         o    PCI-X v1.1 operating up to 133MHz and 64bits

         o    PCI bus spec v2.2 operating up to 66MHz and 64bits

         o    Packetized SCSI at 320 and 160 MB/s

         o    QAS

         o    DT

         o    40MB/sec in single-ended mode and up  to  320MB/sec
              transfer rate in LVD mode

         o    Domain Validation

         o    Retained Training Information (RTI)

         o    PCI and PCI-X Error handling

     Note -

       The adpu320 driver does not support the  HostRAID  feature
       found  on  some  Adaptec SCSI controllers.  For adpu320 to
       support a Adaptec SCSI adapter with HostRAID, you must not

       use any HostRAID features.

  Driver Configuration
     The adpu320 host bus adapter driver is configured by  defin-
     ing  the properties found in adpu320.conf. Properties in the
     adpu320.conf file that can be modified by the user  include:
     ADPU320_SCSI_RD_STRM, ADPU320_SCSI_NLUN_SUPPORT.

       -------------------------------------------------------------
                       Option: ADPU320_SCSI_RD_STRM=[value]
                   Definition: Enables/disables read streaming negotiation
                               for all drives.
              Possible Values: 0 (off), 1 (on)
                Default Value: 0 (off)

                       Option: ADPU320_SCSI_NLUN_SUPPORT=[value]
                   Definition: Enables the number of logical units to be
                               scanned per drive.
              Possible Values: 1-64
                Default Value: 64
            -------------------------------------------------------------




     If you alter or add driver parameters incorrectly,  you  can
     render  your  system  inoperable. Use driver parameters with
     caution.
