The Microsoft-updated ATAPI driver (provided for the Microsoft Windows NT
®
4.0
operating system) offers a performance improvement by off-loading certain functions
from the system processor during multithreaded operations. Dell has installed the
Microsoft-updated ATAPI driver for your operating system, and it is operative when
you receive your computer. No further installation or configuration is needed.
NOTE: If Windows NT 4.0 is reinstalled, the Microsoft-updated ATAPI drivers must
also be reinstalled.
The driver for Windows NT 4.0 has also been copied to your hard-disk drive in
diskette-image form. If you need to reinstall or remove this driver, you can do so as
described in the following subsections.
