Installing and Configuring SCSI Drivers 3-11
Removing a Host Adapter
Removing a PCI expansion-card SCSI controller is as simple as physically removing it
from its slot when your computer is shut down. Windows NT boots and functions
properly in this configuration, but a warning message is generated every time you
boot Windows NT.
CAUTION: If you have removed a host adapter but still have other host
adapters of the same type installed in your computer, do not use
Windows NT Setup to remove the device driver.
To eliminate the warning message, you must update the Windows NT software con-
figuration as follows:
1. Select and start the Windows NT Setup program.
There is a brief pause while Windows NT Setup scans your hardware
configuration.
2. Select the Options pull-down menu, and then select Add/Remove SCSI
Adapters.
The SCSI Adapter setup program displays a list of all host adapters currently
installed.
3. Select the host adapter you want to remove, and click Remove. When
the Windows NT Setup program asks you for confirmation, click OK.
Because SCSI device drivers are loaded during system start-up and because they
may be needed to load Windows NT itself, a message may appear warning you
that Windows NT may not start if you remove the SCSI adapter.
4. When you are sure you are removing the correct host adapter type,
click OK.
5. Return to step 3 if you want to remove driver support for other types
of host adapters, or click Close to exit the SCSI adapters portion of
Windows NT Setup.
6. Close the Windows NT Setup program. When the following message
appears, click OK to exit:
The changes you have made will not take effect until the
computer is restarted.
If this message does not appear, no changes have been made to the
Windows NT system configuration.
7. Restart your computer.
NOTE: The Windows NT Setup program does not delete the device driver from your
hard-disk drive; it only updates Windows NT software configuration information so
that the device driver is no longer loaded during system start-up.
