Installing and Configuring SCSI Drivers 3-132. Shut down Windows NT and replace the existing host adapter.3. Restart your computer and Windows NT.Some drive assignments may have changed from the previous configuration.It is not essential to remove the device driver for the host adapter you are replacing.Windows NT dynamically detects the absence or presence of host adapter hardware,and no problems should arise if you leave the existing device driver installed. You canremove the device driver later, after you have successfully rebooted Windows NT.However, if you leave the driver in, each time you boot the system you may receive anerror message about the extra device driver. See the previous subsection, “Removinga Host Adapter.”7URXEOHVKRRWLQJIRU:LQGRZV176HUYHUThe boot manager for Windows NT contains recovery logic to allow you to return tothe last known good configuration. If you have changed your host adapter configura-tion and Windows NT no longer boots, follow these steps to recover:1.

If the following message appears,press the spacebar, press at the next screen, and then follow the instructionson the screen to continue booting with the last known good configuration:Press spacebar NOW to invoke the Last Known Good menu3. When your computer is operational again, check all of the hardware and softwareconfiguration changes you want to make. Look specifically for conflicts with partsof the existing system configuration that are not being changed.If you cannot determine the source of the error, contact Dell for assistance.
