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

instructions on the screen.

5.4.2.2
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
