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
