+2. Version History
+
+   3.0	  (December 1st, 2005)
+	- Updated driver to use SCSI transport class infrastructure
+	- Upported sequencer and core fixes from adaptec released
+	  version 2.0.15 of the driver.
+
+   1.3.11 (July 11, 2003)
+        - Fix several deadlock issues.
+        - Add 29320ALP and 39320B Id's.
+
+   1.3.10 (June 3rd, 2003)
+        - Align the SCB_TAG field on a 16byte boundary.  This avoids
+          SCB corruption on some PCI-33 busses.
+        - Correct non-zero luns on Rev B. hardware.
+        - Update for change in 2.5.X SCSI proc FS interface.
+        - 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.
+        - Implement controller suspend and resume.
+        - 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.
+
+   1.3.9 (May 22nd, 2003)
+        - Fix compiler errors.
+        - Remove S/G splitting for segments that cross a 4GB boundary.
+          This is guaranteed not to happen in Linux.
+        - Add support for scsi_report_device_reset() found in
+          2.5.X kernels.
+        - Add 7901B support.
+        - Simplify handling of the packetized lun Rev A workaround.
+        - 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.
+
+   1.3.8 (April 29th, 2003)
+        - Fix types accessed via the command line interface code.
+        - Perform a few firmware optimizations.
+        - Fix "Unexpected PKT busfree" errors.
+        - Use a sequencer interrupt to notify the host of
+          commands with bad status.  We defer the notification
+          until there are no outstanding selections to ensure
+          that the host is interrupted for as short a time as
+          possible.
+        - Remove pre-2.2.X support.
+        - Add support for new 2.5.X interrupt API.
+        - Correct big-endian architecture support.
+
+   1.3.7 (April 16th, 2003)
+        - Use del_timer_sync() to ensure that no timeouts
+          are pending during controller shutdown.
+        - For pre-2.5.X kernels, carefully adjust our segment
+          list size to avoid SCSI malloc pool fragmentation.
+        - Cleanup channel display in our /proc output.
+        - Workaround duplicate device entries in the mid-layer
+          device list during add-single-device.
+
+   1.3.6 (March 28th, 2003)
+        - Correct a double free in the Domain Validation code.
+        - Correct a reference to free'ed memory during controller
+          shutdown.
+        - Reset the bus on an SE->LVD change.  This is required
+          to reset our transceivers.
+
+   1.3.5 (March 24th, 2003)
+        - Fix a few register window mode bugs.
+        - Include read streaming in the PPR flags we display in
+          diagnostics as well as /proc.
+        - Add PCI hot plug support for 2.5.X kernels.
+        - Correct default precompensation value for RevA hardware.
+        - Fix Domain Validation thread shutdown.
+        - Add a firmware workaround to make the LED blink
+          brighter during packetized operations on the H2A4.
+        - Correct /proc display of user read streaming settings.
+        - Simplify driver locking by releasing the io_request_lock
+          upon driver entry from the mid-layer.
+        - Cleanup command line parsing and move much of this code
+          to aiclib.
+
+   1.3.4 (February 28th, 2003)
+        - Correct a race condition in our error recovery handler.
+        - Allow Test Unit Ready commands to take a full 5 seconds
+          during Domain Validation.
+
+   1.3.2 (February 19th, 2003)
+        - Correct a Rev B. regression due to the GEM318
+          compatibility fix included in 1.3.1.
+          
+   1.3.1 (February 11th, 2003)
+        - Add support for the 39320A.
+        - Improve recovery for certain PCI-X errors.
+        - Fix handling of LQ/DATA/LQ/DATA for the
+          same write transaction that can occur without
+          interveining training.
+        - Correct compatibility issues with the GEM318
+          enclosure services device.
+        - Correct data corruption issue that occurred under
+          high tag depth write loads.
+        - Adapt to a change in the 2.5.X daemonize() API.
+        - Correct a "Missing case in ahd_handle_scsiint" panic.
+
+   1.3.0 (January 21st, 2003)
+        - Full regression testing for all U320 products completed.
+        - Added abort and target/lun reset error recovery handler and
+          interrupt coalescing.
+
+   1.2.0 (November 14th, 2002)
+        - Added support for Domain Validation
+        - Add support for the Hewlett-Packard version of the 39320D
+          and AIC-7902 adapters.
+        Support for previous adapters has not been fully tested and should
+        only be used at the customer's own risk.
+
+   1.1.1 (September 24th, 2002)
+        - Added support for the Linux 2.5.X kernel series
+
+   1.1.0 (September 17th, 2002)
+        - Added support for four additional SCSI products:
+          ASC-39320, ASC-29320, ASC-29320LP, AIC-7901.
+
+   1.0.0 (May 30th, 2002)

+          Definition: Set IO Cell precompensation value on a per-controller
+                      basis.
+                      Controllers may be omitted indicating that
+                      they should retain the default precompensation setting.
+             Example: precomp:{0x1}
+                        On Controller 0 set precompensation to 1.
+             Example: precomp:{1,,7}
+                        On Controller 0 set precompensation to 1.
+                        On Controller 2 set precompensation to 8.
+                      
+     Possible Values: 0 - 7
+       Default Value: Varies based on chip revision
+   -----------------------------------------------------------------
+              Option: slewrate: {value[,value...]}
+          Definition: Set IO Cell slew rate on a per-controller basis.
+                      Controllers may be omitted indicating that
+                      they should retain the default slew rate setting.
+             Example: slewrate:{0x1}
+                        On Controller 0 set slew rate to 1.
+             Example: slewrate :{1,,8}
+                        On Controller 0 set slew rate to 1.
+                        On Controller 2 set slew rate to 8.
+                      
+     Possible Values: 0 - 15
+       Default Value: Varies based on chip revision
+   -----------------------------------------------------------------
+              Option: amplitude: {value[,value...]}
+          Definition: Set IO Cell signal amplitude on a per-controller basis.
+                      Controllers may be omitted indicating that
+                      they should retain the default read streaming setting.
+             Example: amplitude:{0x1}
+                        On Controller 0 set amplitude to 1.
+             Example: amplitude :{1,,7}
+                        On Controller 0 set amplitude to 1.
+                        On Controller 2 set amplitude to 7.
+                      
+     Possible Values: 1 - 7
+       Default Value: Varies based on chip revision
+   -----------------------------------------------------------------
+
+   Example: 'options aic79xx aic79xx=verbose,rd_strm:{{0x0041}}'
+        enables verbose output in the driver and turns read streaming on
+        for targets 0 and 6 of Controller 0.
+
+4. Additional Notes
+
+   4.1. Known/Unresolved or FYI Issues
+
+        * Under SuSE Linux Enterprise 7, the driver may fail to operate
+          correctly due to a problem with PCI interrupt routing in the
+          Linux kernel.  Please contact SuSE for an updated Linux
+          kernel.
+
+   4.2. Third-Party Compatibility Issues
+
+        * Adaptec only supports Ultra320 hard drives running
+          the latest firmware available. Please check with
+          your hard drive manufacturer to ensure you have the
+          latest version.
+
+   4.3. Operating System or Technology Limitations
+        
+        * PCI Hot Plug is untested and may cause the operating system 
+          to stop responding.
+        * Luns that are not numbered contiguously starting with 0 might not
+          be automatically probed during system startup.  This is a limitation
+          of the OS.  Please contact your Linux vendor for instructions on
+          manually probing non-contiguous luns.
+        * Using the Driver Update Disk version of this package during OS
+          installation under RedHat might result in two versions of this
+          driver being installed into the system module directory.  This
+          might cause problems with the /sbin/mkinitrd program and/or
+          other RPM packages that try to install system modules.  The best
+          way to correct this once the system is running is to install
+          the latest RPM package version of this driver, available from
+          http://www.adaptec.com.
