		3.1.0 Introduction for Windows 2000  


                Windows XP is an operating system designed to run on Intel-architecture
                (32-bit) and Itanium Processor Family (64-bit) processors using current
                technology. It provides a graphical user interface environment incorporating
                many high-level features.  Refer to the Microsoft Windows XP documentation 
                for details.

		An input/output (I/O) manager handles I/O requests in Windows XP. To 
		address a SCSI peripheral, the I/O manager goes through the appropriate 
		drivers. Windows XP 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 and does not require a class
		driver. 

		Microsoft provides the port driver and LSI Logic provides the miniport 
		driver,called SYMMPI.SYS.  This driver completes the path to the LSI Logic 
		controller or processor with an optional SCSI BIOS.

		LSI Logic uses the same filenames for their drivers for different Windows
		operating systems.  The driver files are packaged either in separate
		subdirectories based on the Windows operating system or on different disks.  
		To determine the driver file for Windows XP, note that the filename ends 
		with .SYS.  For example, this driver is SYMMPI.SYS.

		To determine the operating system version, go into Windows Explorer, display
		the driver file, right click on the filename, click Properties, and click
		on the Version tab.  Finally, click the Internal Filename in the lower
		section.  For Windows XP, the filename appears as filename (XP32) for 32-bit
                systems and filename (XP64) for 64-bit systems.

		The next sections describe these drivers and their installation. 

		3.1.1 Features 

		The SYMMPI.SYS miniport driver supports these features:

		o  Supports 320 Mbytes/s parallel SCSI transfers (for LSI453C1020 and 
		   LSI53C1030)
		o  Supports Integrated Mirroring (TM) technology (for LSI453C1020 and 
		   LSI53C1030)
		o  Supports PCI and PCI-X bus protocols (for LSI53C1020 and LSI53C1030)
		o  Supports LSI Logic MPT common software interface 
		o  Supports multiple host adapters 
		o  Supports multiple Logical Unit Numbers (LUNs) 
		o  Supports Scatter-Gather 
		o  Supports SCSI pass-through functionality 
		o  Supports disk array configurations with no LUN 0 
		o  Supports disk array configurations with non-contiguous LUNs 
		o  Auto request sense 
		o  Maximum block size support: 1 Mbyte

		3.1.2 LSI Logic devices supported 

		The name of the SYMMPI.SYS driver is "LSI Logic PCI SCSI/FC MPI Miniport 
		Driver" It supports the following devices and their associated host 
		adapters:
		o  LSI53C1020 (LSI20320)
		o  LSI53C1030 (LSI21320, LSI22320)

		3.1.3 Description

		The SYMMPI.SYS driver meets the Microsoft specification for miniport 
                drivers.  This driver allows connection of parallel SCSI devices
                including disk drives, CD-ROMs, and tape drives for PCI and PCI-X based
                machines. To support a different SCSI device type, the
                Windows XP architecture requires that a class driver for that type of device
                to be present (usually supplied by Microsoft, or possibly by the peripheral
                manufacturer). No changes to SYMMPI.SYS are required. The driver supports 
                only Windows XP and all subsequent Service Packs. 

		A Windows application passes SCSI commands directly to the parallel SCSI 
		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 XP documentation for more details.

		3.2.0 Installing the SYMMPI.SYS driver  

		This procedure installs the SYMMPI.SYS driver onto a new or existing
		Windows XP system. Depending upon the media used to distribute LSI Logic
		drivers (web or CD-ROM), you will create a driver diskette.

		Copy the files listed in this section to the root directory of a clean
		diskette as shown below.  Label this diskette "Windows XP Driver
		Diskette". You will use this diskette during the installation process.

        	\txtsetup.oem
       		\symmpi.tag
                \32_bit\oemsetup.inf
                \32_bit\symmpi.sys
                \64_bit\oemsetup.inf
                \64_bit\symmpi.sys

		3.2.1 New system installation 

		This procedure installs the SYMMPI.SYS driver onto a Windows XP system.
		Use this procedure when installing Windows XP onto an unused drive.
		Windows XP automatically adds the driver to the registry and copies the
		driver to the appropriate directory.

                The method for installing Windows XP on a new system involves using a 
                CD-ROM.  Installation using boot floppy diskettes is not supported by 
                Windows XP.

		3.2.1.1 CD-ROM installation

                1. Start the Windows XP installation by booting from the Windows XP CD-ROM:

                   The system BIOS must support booting from a CD-ROM. BIOS settings may 
                   need to be changed to allow CD-ROM booting.

                2. Press the F6 key to install the SYMMPI.SYS driver when the screen displays
                   "Windows Setup".

                   This must be done or else these new driver installed from the driver
                   diskette will not be recognized.

                   Note: Be sure to press the F6 key as any driver loaded later in the
                   installation process is not recognized by Windows XP Setup. 
                   If F6 is not pressed, all devices controlled by the drivers are
                   not available during Windows XP setup.

                3. Choose S to specify an additional device when the screen displays "Setup
                   was unable to load support for the mass storage device you specified...". 

                   NOTE: If this screen is not displayed as the first user input, then 
                   pressing the F6 key was not seen by the setup program. Reboot the 
                   system and try again.

                   The system prompts for the manufacturer-supplied hardware support disk.

                4. Insert the appropriate driver diskette containing the Windows XP
                   driver required to support your LSI Logic adapter(s) and press Enter.
    
                   Note: You can go to the IBM Support Web site at
                   http://www.ibm.com/pc/support/ to check for the current Windows 2000 
                   drivers. 
  
                5. The screen will display a list of two drivers to select from:

                   "LSI Logic PCI SCSI/FC MPI Driver (XP 32-bit)"
                   "LSI Logic PCI SCSI/FC MPI Driver (XP 64-bit)"
   
                   Select the driver which matches the processor architecture of the system
                   (32-bit or 64-bit). Press Enter to proceed.

                   Return to the Windows XP Setup screen.
 
                6. Press Enter to proceed.

                   The message about setup loading files appears.
 
                7. Follow the Microsoft Windows XP installation procedure at this point.
 
		3.2.2 Existing system installation

                This procedure installs or upgrades the SYMMPI.SYS drivers onto an existing
                Windows XP system.

                NOTE: When a LSI Logic SCSI adapter is added to an existing
                system installation, the new adapter is automatically detected at the
                next reboot. When the Device Driver Wizard appears at boot, click on the
                Next button and continue at step 8 below.

                1. Boot Windows XP and logon as a user that has Administrator priviledges.

                2. For Windows XP Home Edition, click on the Start button, then right-click
                   on the My Computer entry in the menu.
   
                   For Windows XP Professional, right-click on My Computer on the desktop. 

                3. Click on the Properties selection.

                4. Click on the Hardware tab, and then the Device Manager button.

                5. Click the "+" to the left of the SCSI and RAID controllers line.  Find 
                   the adapter desired for the driver upgrade and double-click the entry.  
                   Click on the Driver tab.

                6. Information on the currently installed driver is displayed, and 
                   additional driver details can be viewed by clicking the "Driver Details" 
                   button.

                7. Click on the "Update Driver" button to update the existing driver.  The
                   Hardware Update Wizard begins.
   
                8. Click on the "Install from a list or specific location..." button to 
                   select it, then click on the Next button.

                9. Click on the "Don't search, I will choose the driver to install." button
                   to select it, then click on the Next button.

                10. Click on the "Have Disk" button and type the path to the driver, or 
                    click on the Browse button.  Drivers for 32-bit systems will be in the 
                    "32_bit" directory and drivers for 64-bit systems will be in the 64-bit 
                    directory.  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.

                12. Click on the Next button again to start the driver update.

                    In some cases, a message will display saying that this driver has not
                    passed logo testing. This message informs you that a nonsigned driver is
                    being installed.

                13. Click STOP Installation to cancel the installation if a nonsigned driver
                    is not desired.

                    or

                    Click Continue Anyway to continue the installation.

                    The system will load the driver from the Windows XP driver diskette.
                    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
                    than the boot adapter, the updated driver will become active immediately.
                    For the boot adapter, a message box displays indicating that you must
                    reboot your system for the new driver to take effect.
 
                15. Click on the Finish button to complete the driver upgrade.


		3.2.3 Performance tuning for Windows 2000

                Windows XP has registry entries that can be used to tune the performance 
		of SCSI I/O for certain configurations. The tunable parameters are large 
		transfer block size support and a assured number of concurrent I/Os for a 
		particular SCSI bus.

		3.2.3.1 Large block size support 

		The SYMMPI.SYS drivers can support up to a 1 Mbyte transfer size in 
		Windows XP; however, the default Windows 2000 transfer size is 64 Kbytes. 
		To enable better performance, the driver installation process adds a 
		registry entry to enable a maximum 256 Kbytes transfer size.  Also, the 
		mpi_256K.reg file can be used to set or re-enable a 256 Kbytes maximum, but
		it can be edited to set other maximum transfer sizes that you want. There 
		are two methods to add this registry setting.

		1. Locate the mpi_256K.reg data file (supplied with the driver files) using
   		Windows Explorer and double-click on the file.
 
   		or 

		2. Type at the command prompt:

   		regedit mpi_256K.reg

		This inserts an entry in the registry to enable 256 Kbytes block size
		support. Editing the mpi_256K.reg can set any maximum block size between
		64 Kbytes and 1 Mbyte. The formula to calculate the proper value for
		MaximumSGList is:

    		MaximumSGList = ((Maximum Block Size)/4 Kbytes) +1

		For 256 Kbytes: 256 Kbytes/4 Kbytes = 64, add 1 for 65 (decimal) or 
		0x41 (hexadecimal). The maximum value allowed for MaximumSGLIst is 255 or 
		0xFF. For the particular value of 0xFF, the internal value passed to 
		Windows is increased to 0x101, allowing support for a full 1 Mbyte transfer. 
		Be sure to read the information in the mpi_256K.reg data file before editing 
		it. The system must be restarted for the new registry setting to be
		effective.

		To reset the maximum block size to the default of 64 Kbytes, follow the 
		instructions above, except use mpidfblk.reg as the data file.

                NOTE: For 64-bit systems, the OS page size is 8K instead of 4K.  Therefore,
                the maximum transfer size is 2MB, the default driver installation
                enables support for 512K transfer size, and the formula becomes:
      
                MaximumSGList = (Maximum Block Size)/8K +1

		3.2.3.2 Maximum number of concurrent I/Os (Assured)   
  
		Windows XP guarantees a maximum of 32 concurrent I/Os active on a 
		particular SCSI bus. However, due to the method of memory allocation, the 
		actual limit of concurrent I/Os can vary greatly between various drivers or 
		versions of drivers. This can have a huge impact on performance benchmarking 
		between different driver versions or adapter vendors. In effect, one adapter 
		may actually be able to have 70 or 80 I/Os outstanding, while another 
		adapter could only have 32. This can also affect systems with high 
		performance storage subsystems, such as disk arrays.

		In order to enable better performance, the driver installation process 
		adds a registry entry to support 128 concurrent I/Os. If a different 
		maximum value is not what you want, the file mpi100io.reg can be used to 
		add a registry entry to guarantee the number of concurrent I/Os that 
		you want.

		There are two methods to add this registry setting. One is to locate the
		mpi100io.reg data file (supplied with the driver files) using Windows 
		Explorer and double click on the file. The other method is to type at the 
		command prompt:

     		regedit mpi100io.reg

		This inserts an entry in the registry to guarantee a maximum of 100 
		concurrent I/Os per adapter.

		If a maximum other than 100 is what you want, the mpi100io.reg can be 
		edited; however, setting this value to a high number uses increasing 
		amounts of non-paged pool memory, a critical XP resource. High values for 
		this setting can degrade system performance. Be sure to read the 
		information in the mpi100io.reg data file before editing it.

		The system must be restarted for the new registry setting to be effective.

		To reset the number of concurrent I/Os to the default of 32, 
		follow the instructions above, except use mpidefio.reg as the data file.  

		3.2.3.3 Miniport driver configuration options

		The SYMMPI driver is configured by default to provide optimum performance 
		in most standard systems. Some non-standard systems may require some fine 
		tuning to obtain peak system memory utilization and performance. 

		3.3.0 Troubleshooting 

                The SYMMPI.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. The error codes that are followed by an asterisk are extended error
                codes, only logged if extended error logging is enabled.

                The following error codes all have a value of 0x00000006 at address 0x34 in 
                the error log details.
