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 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 into 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 quickly appears and disappears, 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 and restart the computer.
