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


Registry Parameters for Drivers
===============================

*   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.
