1-2 Quick Installation Procedures
Version 2.1 Copyright © 2002-2003 by LSI Logic Corporation. All rights reserved.
To achieve Ultra320 SCSI performance, you must connect only Low
Voltage Differential (LVD) devices to the host adapter. If you connect
single-ended (SE) devices and LVD devices, the entire bus will drop to
the lower SE speed, limiting bus performance to Ultra SCSI.
The Ultra320 SCSI host adapters support all major operating systems,
such as Windows (NT 4.0, 2000, NET and XP), Linux, NetWare,
UnixWare, SCO OpenServer 5.X, OS/2, and Solaris. Other software
support includes SureLINK™ Domain Validation on Windows systems.
Domain Validation ensures data integrity by intelligently testing the
network before completing negotiation.
The Ultra320 SCSI host adapters utilize Fusion-MPT™ architecture for
all major operating systems, which allows for thinner drivers and better
performance. To obtain a device driver that supports your operating
system, contact the LSI Logic technical support team at 719-533-7230
or visit our website at http://www.lsilogic.com.

1.3 Quick Windows Driver Installation
To load the SYMMPI.SYS miniport driver during a new Windows NT,
Windows 2000, Windows XP or Windows .NET system installation, you
can boot directly from the Microsoft installation CD-ROM. The Windows
drivers are not interchangeable; however, the instructions are very
similar.
To install a new Windows operating system and its appropriate device
driver, follow these steps:
Step 1. Have the Microsoft Windows driver diskette available to insert
into drive A when prompted.
Step 2. Boot the computer from the Microsoft Windows CD-ROM.
Step 3. Press F6 when the words Setup is inspecting your
computer's hardware configuration appear, or when
Windows prompts you for nonsupported drivers.
Important: You must press F6 for the new driver to be recognized. Oth-
erwise, the system does not recognize the devices con-
trolled by the driver during the Windows setup.
Step 4. Follow the instructions until a screen displaying the words
Setup could not determine the type of one or more mass
storage device… appears.
Step 5. Choose S to Specify Additional Devices.
Step 6. Follow the prompts and insert the Windows driver diskette
when prompted.
Step 7. Follow the Microsoft Windows installation procedure to
complete the installation. Microsoft provides documentation
with their installation CD-ROM.
Step 8. If you are installing Windows NT 4.0, also install the Service
Packs 5 or higher after Windows NT 4.0 has been installed.
Note: Refer to the Fusion-MPT™ Device Management User’s
Guide for detailed configuration and installation instructions
for all firmware and drivers.

Step 4. Be sure to tighten the bracket screw into the bracket securely
before you connect the internal and external SCSI devices.
2.2 SCSI Device Cables
For reliable Ultra320 operation, be sure to use an Ultra320 rated SCSI
cable. The Ultra320 SCSI cable also has built-in low voltage differential
and single-ended termination. This built-in feature is included because
most Ultra320 SCSI hard disk drives are not made with on-board low
voltage differential termination.
2.2.1 Internal SCSI Cables
You can connect all internal SCSI devices to the host adapter with an
unshielded, twisted pair, 68-pin ribbon cable. Some 68-pin internal cables
come with a low voltage differential and single-ended terminator on one
end, which must be furthest from the host adapter. Figure 2.3 and
Figure 2.4 show internal cables with and without a terminator.
