.........................................................................
1.0 Introduction for Windows 8 and Windows Server 2012 

Windows 8/2012 is an operating system designed to run on Intel architecture (x86,
32-bit) and Extended-64 (x64, AMD64/EM64T) processors using current
technology. It provides a graphical user interface environment incorporating
many high-level features. Note that Windows Server 2012 is only supported on
x64 processors. Refer to the Microsoft Windows 8 documentation for details.

An I/O manager handles I/O requests in Windows 8/2012. To address a peripheral, the
I/O manager goes through the appropriate drivers. Windows 8/2012 provides class
drivers for hard disk, optical, CD-ROM, printer, and scanner peripherals. Other
class drivers, provided by peripheral manufacturers, may be added to support
new devices. Tape device support is built into the operating system itself and
does not require a class driver. 

Microsoft provides the port driver and Avago Technologies provides the miniport
drivers, which is called LSI_SAS3.SYS.  This driver completes the path to the
LSI controller or processor with an optional SAS BIOS.

This miniport driver uses the Microsoft StorPort port driver (rather than
the Microsoft ScsiPort driver in earlier versions of Windows).  The StorPort
driver has architectural enhancements that provide performance improvements on
large server systems with many storage adapters.  This miniport driver is
designed to take advantage of these enhancements for improved performance.

A new Storport driver feature for Windows 8/2012 is Extended SRB (Storage Request
Block).  This new type of request is very extensible and allows for better
performance and additional new features in future versions of Windows.  The
LSI_SAS3 miniport driver supports Extended SRB.

.........................................................................
1.1 Features 

The LSI_SAS3.SYS miniport driver supports these features:

o  Supports End-to-End Data Protection (EEDP)
o  Supports 1.5Gb, 3Gb, 6Gb and 12Gb SAS expanders/devices and SATA devices
o  Supports PCI-Express bus protocols
o  Supports MSI/MSI-X
o  Supports LSI MPT common software interface 
o  Supports multiple host adapters 
o  Supports multiple Logical Unit Numbers (LUNs) 
o  Supports Scatter-Gather

o  LSISAS-Intruder , Cutlass

.........................................................................
1.3 Description

The LSI_SAS3.SYS driver meets the Microsoft specification for miniport drivers.
These drivers allow connection of SAS devices including disk drives,
CD/DVD-ROMs, and tape drives for PCI-Express based machines. To support a
different SAS device type, the Windows 8 architecture requires that a class
driver for that type of device be present (usually supplied by Microsoft, or
possibly by the peripheral manufacturer). No changes to the LSI drivers are
required. The driver supports only Windows 8/2012 and all subsequent Service Packs. 

A Windows application passes SCSI commands directly to the SAS Protocol devices
by using the SCSI pass-through facility. This facility allows applications to
directly control and access devices by filling in a data structure and calling
into the port or class driver. Refer to the Microsoft Windows 8 documentation
for more details.

............................................................................
2.0 Installing the LSI_SAS3.SYS Driver


This procedure installs the LSI_SAS3.SYS driver onto a new or existing Windows
8 system. Depending upon the media used to distribute LSI drivers (web or
CD-ROM) and the type of adapter, you will create a driver install package on
some type of accessible media.  This can be a diskette, CD or DVD, or USB flash
drive.  The driver install package can also be placed on a hard disk for driver
upgrades only.

Copy the files listed in this section to a folder on the desired media as shown
below. You will use this driver package during the installation process.

        lsi_sas3.inf
        lsi_sas3.sys
        lsinodrv.inf
        wdcfg.exe
        DriverConfigParam.def
        lsi_sas3.cat 
        
Note: Windows drivers must be either Release signed (by LSI) or WHQL logo
      signed (by Microsoft Windows Hardware Quality Labs) to be installed on
      Windows 8/2012.  Any modifications to any of the above files will invalidate
      the digital signature of the package and the OS will not install the
      driver.

............................................................................
2.1 New System Installation 

This procedure installs the LSI_SAS3.SYS driver onto a Windows 8/2012 system. Use
this procedure when installing Windows 8/2012 onto an unused drive. Windows 8/2012
automatically adds the driver to the registry and copies the driver to the
driver storage area.

............................................................................
2.1.1 DVD-ROM Installation

1. Start the Windows 8/2012 installation by booting from the Windows 8/2012 DVD-ROM:

   The system BIOS must support booting from a DVD-ROM. BIOS settings may need
   to be changed to allow DVD-ROM booting.
   
2. Proceed with the installation of Windows 8/2012. When the screen displays
   "Where do you want to install Windows?", click on the Load Driver icon.
   
3. Be sure the media with the LSI_SAS3 driver install package for the system
   processor architecture is inserted in the system.  Click the Browse button,
   browse to the location of the driver package, then click OK.
   
   Note: Current Windows 8/2012 drivers can be downloaded from the Broadcom/Avago Tech

10. Click on the "Have Disk" button and type the path to the driver, or click
    on the Browse button. Select the location for the driver package which
    matches the processor architecture of the system (x86 or x64). After
    the path to the driver has been established, click the OK button.

11. Select the driver from the list and click on the Next button.

    Note: When using a Release Signed driver, a Windows Security dialog box may
          appear, indicating that the publisher of this software is LSI
          Corporation. Click the Install button to continue installation of the
          driver.
            
          A second Windows Security dialog box may appear, indicating that a
          LSI system device is being installed.  This is to install drivers for
          LSI storage enclosure processors.  Click the Install button to
          continue installation of the driver.
          
          
12. The system will load the driver from the Windows 8/2012 driver package media.
    A message box may display indicating that the target (existing) driver is
    newer than the source (upgrade) driver.

14. Click No to cancel the driver upgrade at this point.

      or

    Click Yes to continue the installation.

    The system copies the driver to the system disk. For any adapter other

    your system for the new driver to take effect.

15. Click on the Close button to complete the driver upgrade.

............................................................................
2.3 Performance Tuning for Windows 8/2012

Windows 8/2012 has registry entries that can be used to tune the performance of SCSI
I/O for certain configurations. The registry settings of NumberOfRequests and
MaximumSGList are not used by StorPort and will have no effect on the
LSI_SAS3.SYS driver.

............................................................................
2.3.1 Miniport Driver Configuration Options

The LSI_SAS3.SYS driver is configured by default to provide optimum
performance in most standard systems.

However, it is possible to fine-tune certain driver parameters using a utility
provided on the OS installation disk, the Windows Driver Configuration Utility
(WDCFG).

The WDCFG utility is fully installed automatically as part of the driver
installation.

To use the utility, first launch a Command Prompt window.  In the Command Prompt 
window, enter the "wdcfg -?" command to display full usage information.  The 
usage information explains how to query and set parameters, and how to use the
utility to display a list of driver configuration parameters which can be
controlled using the utility (including full explanations of each).

Note that parameter changes are only activated within the driver following a
driver initialization.  This may be done by restarting the machine, or by using
Device Manager to disable and re-enable the driver (Take care not to do this
to a driver servicing the boot volume).

............................................................................
2.4 WinPE Installation

WinPE is provided to system OEM's to create a Pre-install Environment image.
To use the LSI_SAS3.SYS driver with the Windows 8/2012 based WinPE, perform the
steps listed below.

1. Create an lsi_sas3 folder in the winpe_image directory under i386\system32.
   For example: mkdir winpe_image\i386\system32\lsi_sas3
 
2. Copy the lsi_sas3 driver package to the winpe_image\i386\system32\lsi_sas3
   folder.

3. Edit the winpe_image\i386\System32\Winpeoem.sif to remove the semicolons
   from the [OemDriverParams] section and add the name of the lsi_sas3
   directory to the OemDriverDirs entry. For example:

   [OemDriverParams]
   OemDriverRoot = ""
   OemDriverDirs = lsi_sas3
 
4. You can then use oscdimg to create a bootable .iso image, or follow the
   WinPE User's Guide to create a bootable USB flash device.

............................................................................
3.0 Troubleshooting 

The LSI_SAS3.SYS driver will log error messages to the system error log. For
these errors, the system errorlog EventID will be 11, and the specific error
code values will be displayed at offset 0x10. Data should be displayed in words.
