This Document tries to explain the Structure of the Release Package for MegaRAID Windows Drivers.


Earlier MegaRAID Windows Drivers had a packaging scheme like below .It contained three folders namely. 
win8
x86
x64
A single binary was used on Windows x86 version from Windows Server 2003 upto Windows Server 2008R2 and Single Binary  was used for all the X64 versions. The Win8 Folder was used for Windows8/Windows Server 2012 OS versions.

Recently To make our build infrastructure common to SCS Windows Drivers and MegaRAID Drivers we have choosen good parts from both the builds and made a single build Infrastructure for both SCS and MegaRAID Windows Drivers. 
This will help us in maintaining drivers  easily . 
Instead of building a single driver from Windows server 2003 to Windows 7 , the build infrastructure has been modified to build drivers for each individual OS . 
what this means for Individual OS like windows server 2003 , Windows 7 we will have a separate driver built under a separate directory. 
 
In the Release order package you will see these folders namely srv_2003_x86, srv_2003_x64, srv_2008_x86,srv_2008_x64,vista_x86,vista_x64, win7_x86 , Win7_x64 , Win8_x64 , Win8_x86, Win8.1_x86 , Win8.1x64 and xp_64
So the packaging change what you are seeing is  below.Below is described which driver to be used for which OS .

srv_2003_x64- This driver should be used for Windows server 2003 x64.
