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.
To eliminate the warning message, you must update the Windows NT software con-
figuration as follows:
There is a brief pause while Windows NT Setup scans your hardware
configuration.
The SCSI Adapter setup program displays a list of all host adapters currently
installed.
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.
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.
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.
