If you have Windows NT version 4.0, and you have installed the latest LSI Logic
Windows NT Flint driver (ver. 4.05.00 or later), you can change selected
configuration parameters of your LSI Logic SCSI host adapters by using the 
NTCONFIG utility. You may decide to alter these values if there is a conflict
between device settings or if you need to optimize system performance. The 
system must be rebooted for the changes to take effect.

Note: During boot, the version number of Windows NT appears in a banner on the
      computer monitor.

Since Windows NT and the LSI Logic Windows NT Flint driver do not need the adapter's
BIOS to operate, only a limited number of the configuration parameters that can
be changed by this utility will have any impact on the system once rebooted.
These parameters are: 

     o  SCSI ID of the adapter
     o  Wide data bits setting
     o  Synchronous rate (MB/sec)


*  *  *  *  *  *  * Installing the NTCONFIG utility (x86 platforms) *  *  *  *  *  *  *

To install the NTCONFIG utility using the x86 platforms, follow these steps:

1. Insert the NTCONFIG utility setup diskette into drive A.  

2. Click the Start button on the taskbar and choose Run. 

3. Type A:\SETUP.EXE in the Open field. 

4. Click the OK button and follow the on-screen instructions 
   to install the NTCONFIG Utility. 

A shortcut icon is automatically placed on the desktop at the end of the 
installation process.


*  *  *  *  *  * Installing the NTCONFIG Utility (ALPHA platforms) *  *  *  *  *     

The executable program, NTCONFIG.EXE, can be copied to a directory of the users 
choice. It can then be executed from a command line or a shortcut can be created 
for it and placed on the desktop.


*  *  *  *  *  *  *  *  * Starting the NTCONFIG utility *  *  *  *  *  *  *  *  

To start the NTCONFIG utility, double click on the shortcut icon. After a brief
pause, your computer monitor displays the Main Menu of the utility.

To make changes with this menu driven utility, one or more LSI Logic SCSI
host adapters installed in the system must have NVRAM (non-volatile random 
access memory) to store the changes. Also, due to Windows NT constraints,
each of the adapters must have at least one hard drive attached to it so 
that NTCONFIG can properly identify the adapter.  

IMPORTANT: The NTCONFIG Utility is a powerful tool. The system can be rendered
           inoperable if care is not taken when reconfiguring the parameters.


*  *  *  *  *  *  *  *  *  *  *  * Main Menu   *  *  *  *  *  *  *  *  *  *  *

When you start the LSI Logic NTCONFIG Utility, the main menu appears. This menu 
displays a summary list of all LSI Logic PCI to SCSI host adapters in your system 
and information about each of them.

The main menu screen looks similar to this:

   +-------------------------------------------------------+


*  *  * *  *  *  *  *  *  *  *  * Main Menu Bar *  *  *  *  *  *  *  *  *  *  *

The menu bar offers three items:  File, Options, and Help.  Each item has a
drop-down menu displaying more choices. To familiarize you with this menu bar,
a brief description of the menu items are discussed.

*   *   * File *   *   *

The menu path that appears after clicking on File displays Save and Exit choices.

o  To save NVRAM data pertinent to the adapters via the NTCONFIG Utility, select
   the Save choice.

o  To exit the NTCONFIG Utility, select the Exit choice.

Note: No automatic update to the adapter(s) is done. All changes
      are lost if not already saved by clicking on the Save menu 
      choice above or clicking on the Accept button. 

*   *   * Options *   *   *

To display utility or adapter configuration options,click on the Options 
menu selection. The user may change the language used for the interface
by selecting a language from the list displayed when the Language option
button is pressed. This list is dynamic and is based on the number/type
of language DLLs found in the directory with the executable.

Note:  The NTCONFIG display defaults to the English language. If the display
       language is to be Czechoslovakian, Russian, Korean, or Japanese, you
       must install Windows NT into the corresponding language so that the
       display is readable. This is not applicable to other languages that
       use the Roman Alphabet.  

When the values of the adapters in the NVRAM Found column indicate YES, then
changes are allowed. If the value is NO, the adapter can be selected and default
values are displayed, but no changes are allowed. The two choices available at 
this time are Adapter Settings and Device Selections. 

o  To change settings for adapters, select the Adapter Settings choice.

o  To change settings for SCSI devices, select the Device Selections choice.

In each case, the selected choice displays a menu with adapters found. Click
on the adapter whose related values are to be changed. Depending on the 
selection, either the Adapter Settings Menu or Device Selections Menu appears.
See below for further information regarding these menus.

*   *   *  Help  *   *   *

To display information pertinent to a particular menu screen, click on the Help 
menu selection.

*   *   * Main Menu Button Options *   *   *

At the bottom of the main menu screen, two button options are available:
Accept, and Cancel. Clicking on the Accept button simultaneously saves
the configuration change(s) and exits from the Main Menu. Clicking on the 
Cancel button allows exit from a particular menu level, and discards any changes 
that may have been made.  


*  *  *  *  *  *  *  *  *  * Adapter Settings Menu *  *  *  *  *  *  *  *  *  *  

When you click on an adapter, the corresponding menu appears. Here is an example
of the Adapter Settings menu: 

   +-------------------------------------------------------+
   | Adapter Settings                                      |
   | Help                                                  |
   |                                                       |
   |                                                       |
   |     SCAM Support               On                     |
   |     Parity                     Enabled                |
   |     Host SCSI ID               7                      |
   |     Scan Order                 Low to High <0..Max>   |
   |                                                       |
   |        Set Defaults       Ok         Cancel           |
   |                                                       |
   +-------------------------------------------------------+

To change a setting, double click on it. For example, if you double 
click on SCAM Support, a window appears with two options: On and Off.
Once you click on an option, this window closes and the new values appear
on the Adapter Settings screen.

To set default values, click on the Set Defaults button, and then click on
the Ok button to accept the values. To set changed values, click on the Ok
button. To abort any changes made on this screen, click on the Cancel button.
When you click on the Ok or Cancel button, the system returns to the Main Menu.

The settings in this menu are global settings that affect the selected host
adapter and all SCSI devices attached to it. A brief description of each
setting follows.


*   *   * SCAM Support *   *   *

This BIOS will issue or not issue SCSI Configured AutoMatically (SCAM)
negotiations during initialization based on this parameter. 

Note: Windows NT does not support the use of SCAM, and this selection
      should be turned off. Turning SCAM on may have adverse effects on
      the system.


*   *   * Parity *   *   *

The LSI Logic PCI to SCSI host adapters always generate parity, but some
older SCSI devices do not. Therefore, you are offered the option of disabling
parity checking.

Note:  When disabling parity checking, it is also necessary to disable
       disconnects for all devices, as parity checking for the reselection
       phase is not disabled. If a device does not generate parity, and it
       disconnects, the I/O never completes because the reselection never
       completes.


*   *   * Host SCSI ID *   *   *

This option refers to the host adapter's SCSI ID, which is a unique number
used to identify the device on the SCSI bus.

Note: In general, it is suggested that you not change your host adapter ID from
      the default value of 7, as this gives it the highest priority on the SCSI
      bus. Please also note that if you have 8-bit SCSI devices, they cannot see
      host IDs greater than 7.


*   *   * Scan Order *   *   *

This option allows you to tell your device drivers to scan the SCSI bus from
low to high (0 to max) SCSI ID, or from high to low (max to 0) SCSI ID. If you
have more than one device on the SCSI bus, changing the scan order changes the
order in which drive letters are assigned by the system.

Note: This scan order option may conflict with operating systems that
      automatically assign a drive order.


*  *  *  *  *  *  *  *  *  * Device Selections Menu *  *  *  *  *  *  *  *  *

When you select the Device Selections option, the corresponding menu appears. 
Here is an example of the Device Selections Menu:

   +-------------------------------------------------------------------------+ 
   | Device Selections                                                       | 
   | Help                                                                    | 
   |                                                                         | 
   |                                                                         |

   | +-------------------------------------------------------------------+-+ | 
   |                                                                         | 
   |                                                  Ok     Cancel          | 
   |                                                                         | 
   +-------------------------------------------------------------------------+ 

The settings in this menu affect individual SCSI devices attached to the 
selected host adapter. Double clicking on one of the displayed devices will
allow the user to change the listed options. Use the scroll bar on the 
right side of the Device Selections menu to scroll down the list of possible 
SCSI IDs/devices.


*   *   * Sync Rate (mega bytes/sec) *   *   *

This option defines the maximum data transfer rate the host adapter will attempt
to negotiate. The host adapter and a SCSI device must agree to a rate they can 
both handle. The width column affects this value.


*   *   * Width (bits) *   *   *

This option defines the maximum SCSI data width the host adapter will attempt
to negotiate. The host adapter and a SCSI device must agree to a width they can
both handle. Only host adapters that can do 16-bit data transfers have this 
option enabled. 


*   *   * Disconnect *   *   *


This option tells the host adapter whether or not to allow a device to 
disconnect. SCSI devices have the ability to disconnect from the initiator 
during an I/O transfer. This disconnect frees the SCSI Bus to allow other I/O
processes. Some devices run faster with disconnects enabled (mostly newer 
devices), while some run faster with disconnects disabled (mostly older 
devices).


*   *   * Read Write I/O Timeout (secs) *   *   *

This option sets the amount of time the host adapter waits for a read, write,
or seek command to complete before trying the I/O transfer again. Since this
provides a safeguard allowing the system to recover if an I/O operation fails,
it is recommended that you always set the time-out to a value greater than 
zero.


*   *   * Scan for Device at Boot Time *   *   *

This option can be set to "No" when the user does not want a specific device
available to the system. Also, on a bus with only a few devices attached, you
can speed up boot time by changing this setting to "No" for all unused SCSI IDs.


*   *   * Scan for SCSI Logical Units (LUNs) *   *   *

This option can be set to "No" if you have problems with a device that 
responds to all LUNs whether they are occupied or not. For example, if there 
is a SCSI device with multiple LUNs but you do not want all of those LUNs
to be available to the system, then set this option to "No." This will limit
the scan to LUN0 only.


*   *   * Queue Tags *   *   *

This option enables or disables the issuing of queue tags during I/O requests 
when your device driver can do this.


*  *  *  *  *  *  *  * To exit the NTCONFIG Utility *  *  *  *  *

Since changes only take effect after your system reboots, it is important that
you exit this configuration utility properly. Return to the Main Menu and exit
either by clicking on the Accept button, or follow the menu path: File-->Save
and then click on the Exit choice. If you reboot the system without properly
exiting the utility, these changes may not take effect.


*  *  *  *  *  *  *  *  *  *  * Troubleshooting *  *  *  *  *  *  *  *  *  *

The following is a potential problem and its suggested solution:

If a user selected the Save option under the File menu item, and then proceeds
to attempt more changes, they system becomes hung up. The solution is to exit from
this utility after saving and then re-execute if more changes are necessary.
