8.5.2.2

Updating to QLDIRECT from QLFILTER

The QLDIRECT driver replaces the QLogic QLFILTER driver. You must first uninstall

the QLFILTER driver before installing the QLDIRECT driver.

NOTE: Windows NT does not always remove driver files and registry keys when

uninstalling a driver. You must manually remove the Qlfilter.sys file and

associated registry key to ensure that Windows NT does not load the

Qldirect.sys and Qlfilter.sys drivers.

Perform the following steps to update from the QLFILTER driver to the QLDIRECT

driver:

1. Manually delete the Qlfilter.sys file from the following directory. For example:

del C:\Winnt\System32\Drivers\Qlfilter.sys

2. Manually remove the QLFILTER key from the following registry location:

\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

3. Insert the disk that contains the QLDIRECT driver in an appropriate drive.

4. Execute the Setup.exe installation program on the disk and follow the

instructions on the screen.

5. Remove the disk that contains the QLDIRECT driver.

6. Restart your system to load the driver.
