1.0 Introduction for Windows XP x64
Windows XP x64 is an operating system designed to run on Extended-64
(AMD64/EM64T) processors using current technology. It provides a graphical
user interface environment incorporating many high-level features. Refer to the
Microsoft Windows XP x64 documentation for details.
An I/O manager handles I/O requests in Windows XP x64. To address a
peripheral, the I/O manager goes through the appropriate drivers. Windows
XP x64 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 LSI Logic provides the miniport drivers,
which are called LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.SYS. These drivers
complete the path to the LSI Logic controller or processor with an optional
U320 SCSI, Fibre Channel or SAS BIOS.
These miniport drivers use 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. These miniport drivers are
designed to take advantage of these enhancements for improved performance.
.........................................................................
1.1 Features

.........................................................................
1.3 Description
The LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.SYS drivers meet the Microsoft
specification for miniport drivers. These drivers allow connection of
parallel SCSI, Fibre Channel and SAS devices including disk drives, CD-ROMs,
and tape drives for PCI and PCI-X based machines. To support a different
parallel SCSI, Fibre Channel or SAS device type, the Windows XP x64
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
XP x64 and all subsequent Service Packs.
A Windows application passes SCSI commands directly to the parallel SCSI,
Fibre Channel or 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 XP x64 documentation for more details.
............................................................................
2.0 Installing the LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.SYS Drivers
This procedure installs the LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.SYS drivers
onto a new or existing Windows XP x64 system. Depending upon the media
used to distribute LSI Logic drivers (web or CD-ROM) and the type of adapter,
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 x64 Driver
Diskette". You will use this diskette during the installation process.
For LSI_SCSI:
\txtsetup.oem
\lsi_scsi.tag
\pxpam64.cat
\lsi_scsi.inf
\lsi_scsi.sys
For LSI_FC:
\txtsetup.oem
\lsi_fc.tag
\fxpam64.cat
\lsi_fc.inf
\lsi_fc.sys
For LSI_SAS:
\txtsetup.oem
\lsi_sas.tag
\sxpam64.cat
\lsi_sas.inf
\lsi_sas.sys
For the following driver installation sections, the designation LSI_xxx is used
to indicate the LSI_SCSI, LSI_FC or LSI_SAS driver, depending on which driver
is being installed.
............................................................................
2.1 New System Installation
This procedure installs the LSI_xxx.SYS driver onto a Windows XP x64
system. Use this procedure when installing Windows XP x64 onto an
unused drive. Windows XP x64 automatically adds the driver to the
registry and copies the driver to the appropriate directory.
Note: Windows XP x64 contains a SYMMPI.SYS driver that supports the
U320, 919 and 929 devices. When performing a fresh installation with a
device that is supported by the bundled SYMMPI.SYS driver, loading
of the LSI_xxx.SYS driver using the F6 key will have no effect and
the SYMMPI.SYS driver will be used. To use the LSI_xxx.SYS driver,
upgrade the driver after installation has completed as described
in Section 2.2.
The method for installing Windows XP x64 on a new system involves using
a CD-ROM. Installation using boot floppy diskettes is not supported by
Windows XP x64.
............................................................................
2.1.1 CD-ROM Installation
1. Start the Windows XP x64 installation by booting from the Windows
XP x64 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 LSI_xxx.SYS driver when the screen displays
"Windows Setup".
This must be done or else the new driver 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 x64 Setup.
If F6 is not pressed, all devices controlled by the drivers are
not available during Windows XP x64 setup.
3. Choose S to specify an additional device when the screen displays "Setup
could not determine the type of one or more mass storage devices...".
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 x64
driver required to support your LSI Logic adapter(s) and press Enter.
Note: Current Windows XP x64 drivers can be downloaded from the
LSI Logic web site at:
http://www.lsilogic.com/downloads/selectDownload.do
After you are connected to this web site, select the product
category, family, and the appropriate product. Select the Driver
checkbox and click Go. Click on the desired Windows XP x64 driver
to begin the download.
5. The screen will display the driver to be installed:
"LSI Logic Fusion-MPT xxx Driver (XP x64)"
(where xxx is SCSI, FC, or SAS depending on the driver beign installed)
Press Enter to proceed.
Return to the Windows XP x64 Setup screen.
6. Press Enter to proceed.
The message about setup loading files appears.
7. Follow the Microsoft Windows XP x64 installation procedure at this point.
............................................................................
2.2 Existing System Installation
This procedure installs or upgrades the LSI_xxx.SYS drivers onto an existing
Windows XP x64 system.
NOTE: When a LSI Logic SCSI, Fibre Channel or SAS 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 x64 and logon as a user that has Administrator
privileges.
2. Click on the Start button, then right-click on the My Computer entry in
the menu.
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. 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.
Note: Drivers are digitally signed by the Microsoft Windows Hardware
Quality Lab (WHQL) on completion of logo testing. Due to the time
lag between the general customer release by LSI of Windows drivers
and the completion of WHQL logo testing, some drivers distributed
with adapters or downloaded from the www.lsilogic.com web site may
not be digitally signed.
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 x64 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.

2.3 Performance Tuning for Windows XP x64
Windows XP x64 has registry entries that can be used to tune the
performance of SCSI I/O for certain configurations. The tunable parameter
for LSI_xxx.SYS is a guaranteed number of concurrent I/Os for a particular
SCSI bus.
............................................................................
2.3.1 Maximum Number of Concurrent I/Os (Guaranteed)
Windows XP x64 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 the best performance, the driver installation process adds a
registry entry to support 255 concurrent I/Os. If a different maximum value is
desired, the file mpi100io.reg can be used to add a registry entry to guarantee
the desired number of concurrent I/Os.
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 desired, the mpi100io.reg can be edited;
however, setting this value to a high number uses increasing amounts of
non-paged pool memory, a critical Windows 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 rebooted for the new registry setting to be effective.
To reset the guaranteed number of concurrent I/Os to the operating system
default of 32, follow the instructions above, except use mpidefio.reg as the
data file.
............................................................................
2.3.2 Miniport Driver Configuration Options
The LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.SYS drivers are configured by default
to provide optimum performance in most standard systems. Some non-standard
systems may require fine tuning to obtain peak system memory utilization and
performance. After installation, if less than advertised functionality and
performance is observed on any platform, please contact LSI Logic support.
Go to the LSI Logic Technical Support Home Page, which is located at:
http://www.lsilogic.com/support/index.html
and call the listed number for assistance.
LSI Logic can provide additional registry settings if required, to customize
the driver for specific systems and applications.
............................................................................
3.0 Troubleshooting
The LSI_SCSI.SYS, LSI_FC.SYS and LSI_SAS.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.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
