Removing the QLogic BCM57xx and BCM57xxx
Device Drivers
Uninstall the QLogic BCM57xx and BCM57xxx device drivers from your system
only through the InstallShield wizard. Uninstalling the device drivers with Device
Manager or any other means may not provide a clean uninstall and may cause the
system to become unstable. For information on uninstalling QLogic BCM57xx and
BCM57xxx device drivers, see “Removing the Device Drivers” on page 78. When
removing the device drivers, QLogic Control Suite is also removed as well as all
other management applications.
If you manually uninstalled the device drivers with Device Manager and attempted
to reinstall the device drivers but could not, run the Repair option from the
InstallShield wizard. For information on repairing QLogic BCM57xx and
BCM57xxx device drivers, see “Repairing or Reinstalling the Driver Software” on
page 77.
