4. New Version Release: 	5.33  
5. Previous Version Release: 	5.25

------------------------------------------------------------------------------------------------
Reason for Release (including Bug Fixes and Enhancements and Feature added)

Version#: 5.33
=========
Bugs Fixed:
-----------
1) A single Tape drive was seen at TargetID 0 and TargetID 16 on the physical channel.
   One can attach up to a maximum of 15 devices on a single physical channel. All the 
   requests coming for a physical channel with TargetID greater than 15 should be returned as 
   Illegal request. This problem is fixed in the Driver.

Version#: 5.32
=========
Bugs Fixed:
-----------
1) During Logical drives creation/deletion, sometimes Configuration Utility used to hang as it keeps on 
   waiting for the notification of the drive created/removed. 
   This issue has been resolved in the driver by sending notification to the System Manager about 
   the arrival/removal of a logical drive.

Version#: 5.31
=========
Bugs Fixed:
-----------
1) Bug fixed in the Read/Write path, in case of SCSI Channel, with PAE support enabled.

Version#: 5.30
==========
Bugs Fixed:
-----------
1) Updated INF file for OEMs.


Version#: 5.29
=========
Bugs Fixed:
-----------
1) Miniport driver was scanning Qlogic Chips for 511 controllers.
   This problem was causing the driver to scan for the Qlogic chips during
   boot up or during hibernation, which was resulting in the system hang.
   This problem has been fixed by disabling scan of Qlogic chips for the 511 controllers.

Version#: 5.28
==========
Bugs Fixed:
-----------
1) In case of cluster reset, Driver was not waiting for all the commands to complete, 
   resulting in the system crash/hang.

2) Megasign support added to the driver.


Version#: 5.27
=============
Bugs Fixed:
-----------
1) In case of reset, driver was not able to complete all outstanding commands
   to OS, results in lockup in system. This is fixed by purging all the outstanding commands with driver; 
   so OS will retry those commands and system will not lockup.

2) Ghost drive seen when installing Win2k with 5.26 driver in cluster environment. There was a 
   mismatch while calculating the logical drive number.

3) During Tape erase, if Ios are running on the logical disk, the Ios used to slow down.
   Since Tape Erase is a untagged command, Miniport driver handles this request in a different manner. 
   This special handling overcomes the IO slowdown.

Version#: 5.26
==============
Bugs Fixed:
-----------
1) When the MegaRAID Controller is being used as a secondary controller, system hung for the first time 
   whenever it tries to load the driver. This has been fixed.

2) Added support for MultiLun devices such as MultiLun Tapes. 

3) Support for 511 IDE controller added.

Features not supported:
=======================

1) No merging of Sequential Reads and Writes.
