======================================================================
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.)
======================================================================
8. Diskette Content
-------------------
The following files on this disk support Windows NT:
* QLOGIC - Diskette identification file
* TXTSETUP.OEM - Driver installation script for initial Windows
NT text setup
