-------------------------------------------------------------

5.1.1. Installing Windows NT 4.0 from the CD-ROM
------------------------------------------------

1. Set your system to boot to CD-ROM first. If you are booting from 
   IDE CD-ROM, change the system's CMOS setting. If you are booting

3. Select "Other" and press ENTER.
4. Insert the QLogic software diskette and press ENTER.
5. Select the "QLogic QLA12160" and press ENTER.
6. Follow the standard installation procedure and complete the OS 
   installation.


======================================================================

5.2. Adding the QLogic Controller to the Existing OS

1. Ensure power is removed from the system you intend to install 
   QLogic 12160 HBA.
2. Insert the controller in the appropriate slot in your computer
   according to the Hardware Installation Guide (available on

       CD \WINNT\SYSTEM32\DRIVERS

3. Make a backup copy of the old driver:

       COPY QL12160.SYS QL12160.SAV

4. Insert the diskette with updated driver and copy it over the old 
   driver:

       COPY A:\NT\QL12160.SYS

5. Shutdown and reboot the system to use the updated driver.

======================================================================

7. Driver Parameters
--------------------

The driver parameters are divided into System Parameters and NVRAM 
Parameters sections.

======================================================================

7.1. System Parameters
----------------------

* MaximumSGList

  Windows NT includes enhanced scatter/gather list support for doing
  very large SCSI I/O transfers. Windows NT supports up to 256 
  scatter/gather segments of 4096 bytes each, allowing transfers up 
  to 1048576 bytes.

  NOTE: the OEMSETUP.INF file has been updated to automatically update
        the registry to support 65 scatter/gather segments.  Normally,
        no additional changes will be necessary as this typically 
        results in the best overall performance.

  If you wish to alter this value, please use the following procedure:

  1. Click on "Start", select "Run", and open the REGEDT32 program.
  2. Select HKEY_LOCAL_MACHINE and follow the tree structure down to
     the QLogic driver as follows:

         HKEY_LOCAL_MACHINE
             SYSTEM
                 CurrentControlSet
                     Services
                         Ql12160

  3. Select the "Ql12160" key and use Edit/Add Key to create a new
     subkey named "Parameters".
  4. Select the new "Parameters" key and use Edit/Add Key to create
     a new "Device" subkey.  If multiple adapters are installed, 
     you can specify separate subkeys for each adapter by using a 
     subkey name of "DeviceN", where N = the SCSI host adapter number
     (0, 1, 2, etc.).
     The tree structure should now look as follows:

          HKEY_LOCAL_MACHINE
              SYSTEM
                  CurrentControlSet
                      Services
                          Ql12160
                              Parameters
                                  Device   (or DeviceN)

  5. Select the "Device" key and use Edit/Add Value to add a new 
     value name of "MaximumSGList".  Set the data type to REG_DWORD 
     and enter a value from 16 to 255 (10 hex to FF hex).  A value of
     255 (FF hex) enables the maximum 1 MByte transfer size.  Setting
     a value higher than 255 results with the default of 64K 
     transfers.  The default we use is 65 (41 hex).
  6. Exit the Registry Editor, then shutdown and reboot the system.


======================================================================

7.2. NVRAM Parameters
---------------------

The NVRAM features described below are hard-coded in the driver. The
changes made for the particular NVRAM feature in the Fast!Util do 
not take effect unless otherwise noted.

* Support for 32 LUNs

  The driver supports up to 32 LUNs. (During the installation of the
  operating system, Windows NT recognizes up to 8 LUNs.)
