1. OEM Name: 			LSI

2. Product Name: 		MegaRAID Windows NT 4.0 Driver (Mraid35x.sys) 

3. Release Date: 		10/04/2002

4. New Version Release: 	4.10

5. Previous Version Release: 	4.09


Version: 4.10
=============

Bug Fix:
-------
1. Utilities are issuing 0xc3 calls for getting the logical drive statistics.
   We have seen some utilities are requesting 40LD statistics but send buffer 
   less than 40LD statistics size. This is causing the system to crash. 
   This bug has been fixed in the driver by returning all the calls with less 
   buffer size (< 40LD statistics size) without copying any data successfully.


Version: 4.09
=============

Enhancements:
-------------
1. Support added for 520 and 518 controllers.



   
Known Restrictions/Bugs:

1. Performance will degrade if NT service pack 5 or higher is not installed.


Installation Procedure:
----------------------         
1. To install the MegaRAID driver during installation of NT from floppy diskettes, select S at the 
   appropriate time to select the MegaRAID driver on diskette.  
2. If installing NT from a bootable CD (IDE or non-MegaRAID SCSI), press the F6 key when the following 
   message is displayed:

   "Setup is inspecting your computers' hardware configuration."
   Then select S at the appropriate time and select the MegaRAID driver on diskette.


Driver Installation Upgrade:
----------------------------
1. To install the MegaRAID driver on an existing NT configuration, select the SCSI Adapters in the NT 
   Control Panel.  
2. Select the Driver tab and select the Add button.  
3. Any previously installed MegaRAID Drivers should be removed prior to installing a new one. Select the 
   Remove button to remove the driver. 
 


Determining the version number of the MegaRAID driver
