     1. No BIOS support
     2. DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus
     3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
     4. All three SCSI connectors may be used simultaneously without
        SCSI "stub" effects.
  
  2. Version History
     7.0	  (4th August, 2005)
  	- Updated driver to use SCSI transport class infrastructure
  	- Upported sequencer and core fixes from last adaptec released
  	  version of the driver.
     6.2.36 (June 3rd, 2003)
          - Correct code that disables PCI parity error checking.
          - Correct and simplify handling of the ignore wide residue
            message.  The previous code would fail to report a residual
            if the transaction data length was even and we received
            an IWR message.
          - Add support for the 2.5.X EISA framework.
          - Update for change in 2.5.X SCSI proc FS interface.
          - Correct Domain Validation command-line option parsing.
          - When negotiation async via an 8bit WDTR message, send
            an SDTR with an offset of 0 to be sure the target
            knows we are async.  This works around a firmware defect
            in the Quantum Atlas 10K.
          - Clear PCI error state during driver attach so that we
            don't disable memory mapped I/O due to a stray write
            by some other driver probe that occurred before we
            claimed the controller.
  
     6.2.35 (May 14th, 2003)
          - Fix a few GCC 3.3 compiler warnings.
          - Correct operation on EISA Twin Channel controller.
          - Add support for 2.5.X's scsi_report_device_reset().
  
     6.2.34 (May 5th, 2003)
          - Fix locking regression introduced in 6.2.29 that
            could cause a lock order reversal between the io_request_lock
            and our per-softc lock.  This was only possible on RH9,
            SuSE, and kernel.org 2.4.X kernels.
  
     6.2.33 (April 30th, 2003)
          - Dynamically disable PCI parity error reporting after
            10 errors are reported to the user.  These errors are
            the result of some other device issuing PCI transactions
            with bad parity.  Once the user has been informed of the
            problem, continuing to report the errors just degrades
            our performance.
  
     6.2.32 (March 28th, 2003)
          - Dynamically sized S/G lists to avoid SCSI malloc
            pool fragmentation and SCSI mid-layer deadlock.
  
     6.2.28 (January 20th, 2003)
          - Domain Validation Fixes
          - Add ability to disable PCI parity error checking.
          - Enhanced Memory Mapped I/O probe
  
     6.2.20 (November 7th, 2002)

          WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
                   INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
                   USE THEM WITH CAUTION. 
  
     Put a .conf file in the /etc/modprobe.d directory and add/edit a
     line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
     'command' is one or more of the following:
     -----------------------------------------------------------------
                Option: verbose
            Definition: enable additional informative messages during
                        driver operation.
       Possible Values: This option is a flag
         Default Value: disabled
     -----------------------------------------------------------------
                Option: debug:[value]
            Definition: Enables various levels of debugging information
       Possible Values: 0x0000 = no debugging, 0xffff = full debugging
         Default Value: 0x0000
     -----------------------------------------------------------------
                Option: no_probe
                Option: probe_eisa_vl
            Definition: Do not probe for EISA/VLB controllers.
                        This is a toggle.  If the driver is compiled
                        to not probe EISA/VLB controllers by default,
                        specifying "no_probe" will enable this probing.
                        If the driver is compiled to probe EISA/VLB
                        controllers by default, specifying "no_probe"
                        will disable this probing.
       Possible Values: This option is a toggle
         Default Value: EISA/VLB probing is disabled by default.
     -----------------------------------------------------------------
                Option: pci_parity
            Definition: Toggles the detection of PCI parity errors.
                        On many motherboards with VIA chipsets,
                        PCI parity is not generated correctly on the
                        PCI bus.  It is impossible for the hardware to
                        differentiate between these "spurious" parity
                        errors and real parity errors.  The symptom of
                        this problem is a stream of the message:
      "scsi0: Data Parity Error Detected during address or write data phase"
                        output by the driver.
       Possible Values: This option is a toggle
         Default Value: PCI Parity Error reporting is disabled
     -----------------------------------------------------------------
                Option: no_reset
            Definition: Do not reset the bus during the initial probe
                        phase
       Possible Values: This option is a flag
         Default Value: disabled
     -----------------------------------------------------------------
                Option: extended
            Definition: Force extended translation on the controller
       Possible Values: This option is a flag
         Default Value: disabled
     -----------------------------------------------------------------
                Option: periodic_otag
            Definition: Send an ordered tag periodically to prevent
                        tag starvation.  Needed for some older devices
       Possible Values: This option is a flag
         Default Value: disabled
     -----------------------------------------------------------------
                Option: reverse_scan
            Definition: Probe the scsi bus in reverse order, starting
                        with target 15
       Possible Values: This option is a flag
         Default Value: disabled
     -----------------------------------------------------------------
                Option: global_tag_depth:[value]
            Definition: Global tag depth for all targets on all busses.
                        This option sets the default tag depth which
                        may be selectively overridden vi the tag_info
                        option.
       Possible Values: 1 - 253
         Default Value: 32
     -----------------------------------------------------------------
                Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
            Definition: Set the per-target tagged queue depth on a
                        per controller basis.  Both controllers and targets
                        may be omitted indicating that they should retain
                        the default tag depth.
              Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
                          On Controller 0
                            specifies a tag depth of 16 for target 0
                            specifies a tag depth of 64 for target 3
                            specifies a tag depth of 8 for targets 4 and 5
                            leaves target 6 at the default
                            specifies a tag depth of 32 for targets 1,2,7-15
                          All other targets retain the default depth.
  
                        tag_info:{{},{32,,32}}
                          On Controller 1
                            specifies a tag depth of 32 for targets 0 and 2
                          All other targets retain the default depth.
                          
       Possible Values: 1 - 253
         Default Value: 32
     -----------------------------------------------------------------
                Option: seltime:[value]
            Definition: Specifies the selection timeout value
       Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
         Default Value: 0
     -----------------------------------------------------------------
                Option: dv: {value[,value...]} 
            Definition: Set Domain Validation Policy on a per-controller basis.
                        Controllers may be omitted indicating that
                        they should retain the default read streaming setting.
               Example: dv:{-1,0,,1,1,0}
                          On Controller 0 leave DV at its default setting.
                          On Controller 1 disable DV.
                          Skip configuration on Controller 2.
                          On Controllers 3 and 4 enable DV.
                          On Controller 5 disable DV.
  
       Possible Values: < 0 Use setting from serial EEPROM.
                        0 Disable DV
                        > 0 Enable DV
  
         Default Value: SCSI-Select setting on controllers with a SCSI Select
                        option for DV.  Otherwise, on for controllers supporting
                        U160 speeds and off for all other controller types.
     -----------------------------------------------------------------
  
     Example:
     'options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1'
          enables verbose logging, Disable EISA/VLB probing,
          and set tag depth on Controller 1/Target 2 to 10 tags.
