5. Previous Version Release: 	5.38

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

Version 5.39:
============

Bugs Fixed:
----------

1) During Cluster HCT phase 5 test driver and firmware used to wait each other for command 
   completion and interrupt post acknowledgment respectively. This leads to dead lock and 
   HCT test fails with IO timeout error. This has been fixed.

2) When heavy I/O are running, miniport driver often gets mailbox busy this was leading to 
   I/O hangs, in this case driver waits for busy to become free. This has been fixed. 

3) Logical drive status checking was failing for Dummy Device inquiry. This has been fixed.

4) Capability pointer changed in Firmware for Fast READ/WRITE calls for hard disk connected to 
   SCSI Channels.

Enhancements:
------------
1) Support for SATA 150-6 added to the setup files.

2) Support for MegaRAID SCSI 320-2X added to the setup files.

3) Support for SATA 150-4 controllers added to the setup files.



Version 5.38:
============

Bugs Fixed:
----------


1) Change in the setup files, so that Scsiport driver should give correct DeviceNumber and 
   Function Number to the miniport driver.

2) A timeout is implemented in the driver so that driver shouldnt wait infinitely for the 
   Firmware to acknowledge the interrupt.

3) During Reset, Driver was not clearing all the Pending Commands whenever the 
   Firmware is not able to complete it.

4) System was hanging after it wakes up from Hibernation/Standy on 471/493 controller. 
   Driver needs to reprogram these SCSI chips before waiting for the firmware to initialize.


Enhancements:
------------

1) Support for SATA Controller added.
2) Support for the SCSI 320-2 processor added.
