                - Send all of the commands on the queue at once rather than
                  one at a time since the card will support it.

        0.99.02 - Added some additional debug statements to print out
                  errors if an error occurs while trying to read/write
                  to a logical drive (IPS_DEBUG).

                - Fixed read/write errors when the adapter is using an
                  8K stripe size.
