Installing and Configuring SCSI Drivers3-13
2. 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 can
remove 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 an
error message about the extra device driver. See the previous subsection, Removing
a Host Adapter.

The boot manager for Windows NT contains recovery logic to allow you to return to
the 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. Undo any hardware changes you have made to the computer since it was last
operational.
2. Reboot the computer.
Watch the display carefully during start-up. If the following message appears,
press the spacebar, press <l> at the next screen, and then follow the instructions
on the screen to continue booting with the last known good configuration:

3. When your computer is operational again, check all of the hardware and software
configuration changes you want to make. Look specifically for conflicts with parts
of the existing system configuration that are not being changed.
If you cannot determine the source of the error, contact Dell for assistance. See Chap-
ter 12, Getting Help, in the Installation and Troubleshooting Guide for instructions
on contacting Dell for technical assistance.
