QLogic QLA12160 Miniport Driver for Windows NT * This release has been tested with Windows NT Version 4.00. Earlier versions of NT are not supported. * The following files on this disk support Windows NT: QLOGIC Diskette identification file TXTSETUP.OEM Driver installation script for initial Windows NT text setup \NT\OEMSETUP.INF Driver installation script for the Windows NT Setup program \NT\QL12160.SYS QLogic QLA12160 miniport driver for Windows NT \NT\README.TXT This file * If the miniport driver is already installed and you are installing an updated version of the driver, follow this procedure: 1. Open a DOS Command Prompt window. 2. Change the current directory to the NT driver directory: 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. * To initially install the QLogic miniport driver on an installed Windows NT system, follow this procedure: 1. Click on "Start". 2. Under "Settings", click on "Control Panel". 3. Select "SCSI Adapters" from the Control Panel. 4. Select the "Drivers" tab and then click on "Add". 5. Click on "Have Disk". 6. Insert the QLogic software diskette. 7. Enter "A:\NT" for the path to NT driver and click "OK". 8. Choose "QLogic QLA12160, 64 bit PCI DUAL SCSI HBA" and click "OK". 9. Select "Yes" to restart system. * To initially install Windows NT on the boot disk attached to the QLogic QLA12160 adapter, follow this procedure: 1. Start NT installation procedure using Windows NT Setup diskettes. 2. After the standard devices have been detected and configured, use "S" option to "Specify Additional Device". 3. Select "Other" and press ENTER. 4. Insert the QLogic software diskette and press ENTER. 5. Select the "QLogic QLA12160" and press ENTER. 6. Continue with standard installation procedure. * Windows NT Version 4.0 includes enhanced scatter/gather list support for doing very large SCSI I/O transfers. NT 4.0 supports up to 256 scatter/gather segments of 4096 bytes each, allowing transfers up to 1048576 bytes. By default, transfers are limited to 65536 bytes. Enabling the large transfers requires the addition of a new subkey in the registry. Use the following procedure to add the new subkey: NOTE: the OEMSETUP.INF file has been updated to automatically update the registry to support 65 scatter/gather segments. This provides the best overall performance. If you must change this value, 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. Default value is 65 (41 hex). 6. Exit the Registry Editor, then shutdown and reboot the system.Download Driver Pack
