                                 RELEASE NOTES

o The error reporting functionality has been greatly improved.  The driver now
  queries the controller every 7 seconds to collect status information, and
  reports on progress rebuilding logical drives at most every 60 seconds.
  The status of all physical disk drives is also queried as well as updates
  to the controller's internal error log.  This functionality allows for
  more accurate reporting of the cause of drive failures when they occur.

o The production model AcceleRAID controllers are now supported.  Mylex had
  unfortunately provided me with pre-production AcceleRAID units which differed
  in critical ways from the production models, and so the Beta2 driver release
  did not function properly.

o New releases of the Linux Symbios driver now contain code to notice when
  motherboard Symbios chips are controlled by an AcceleRAID and to not
  interfere with operation of the AcceleRAID board.  A patch is also available
  for the Symbios driver version 3.0i.

o A bug was corrected where functionality necessary for swapping to files was
  not implemented.

                                 RELEASE NOTES

o The Mylex AcceleRAID 250 (DAC960PTL-1) and AcceleRAID 200 (DAC960PTL-0)
  models are now supported.  Please note that if you use an AcceleRAID 200,
  or an AcceleRAID 250 configured to use the Symbios chips on the motherboard,
  then the Symbios driver must not be included in the Linux kernel.  This
  restriction will be removed in a future release of these drivers.

o This version of the DAC960 driver uses a more efficient interface for
  communicating with the AcceleRAID 250, AcceleRAID 200, DAC960PJ, and
  DAC960PG models.

o A bug was corrected where the cache was not flushed at shutdown on systems
  with a DAC960 Logical Drive mounted as the root file system.  This only
  affected systems where the DAC960 Logical Drive was configured for write back
  operation without a battery backup unit installed and the system was powered
  off within a couple of seconds of system shutdown.
