Select the host adapter you want to remove, andclick Remove. When the Windows NT Setup pro-gram asks you for confirmation, click OK.Because SCSI device drivers are loaded during sys-tem start-up and because they may be needed to loadWindows NT itself, a screen may appear warningyou that Windows NT may not start if you removethe SCSI adapter.4. When you are sure you are removing the correcthost adapter type, click OK.5. Return to step 3 if you want to remove driver sup-port for other types of host adapters, or clickClose to exit the SCSI adapters portion of Win-dows NT Setup.6. Close the Windows NT Setup program.

Install the driver for the new host adapter by fol-lowing the steps in “Installing or Updating theDriver With Windows NT 3.51” earlier in thissection.It is not essential to remove the device driver for thehost adapter you are replacing. Windows NT dynam-ically detects the absence or presence of host adapterhardware, and no problems should arise if you leavethe existing device driver installed. You can removethe device driver later, after you have successfullyrebooted Windows NT. However, if you leave thedriver in, the system alerts you with an error mes-sage about the extra device driver every time youboot. See “Removing a Host Adapter” earlier in thissection for more information.2. Once the new device driver is installed, shut downWindows NT and replace the existing hostadapter.3. Restart your computer and Windows NT.Some drive letter assignments may have changedfrom the previous configuration.Troubleshooting for Windows NT ServerThe boot manager for Windows NT contains recoverylogic to allow you to return to the last known goodconfiguration.
