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

   Driver Configuration
       The adpu320 host bus adapter driver is configured by defining 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.
