Reinstalling the Microsoft® Windows NT® 4.0 Microsoft-Updated ATAPI Driver | Removing the Windows NT 4.0 Microsoft-Updated ATAPI Driver
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.
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.
Reinstalling the Microsoft Windows NT 4.0 Microsoft-Updated ATAPI Driver
To reinstall the Microsoft-updated ATAPI driver for Windows NT 4.0, perform the following steps:
1. If you have not already done so, use the Program Diskette Maker to make a diskette copy of the Dell Microsoft-updated ATAPI driver diskette image on your
hard-disk drive.
The Program Diskette Maker is available through the Dell Accessories program folder. For more information, refer to the online help provided in the Program Diskette Maker.
2. Start the Windows NT operating system. If you are already running Windows NT, close any open documents or application programs.
3. Insert the Microsoft updated ATAPI driver diskette in drive A.
4. Click the Start button.
5. Click Run, type
a:\setup.bat in the Run window, and then click OK.
A black screen will quickly appear and disappear, which indicates that the driver file has been loaded. Setup automatically saves the existing atapi.sys driver as atapi.000 and loads
the new driver into the system32\drivers subdirectory in the Windows NT directory.
6. Remove the diskette from drive A. Then restart the computer.
