Reinstalling the Windows NT 4.0 Microsoft Updated ATAPI Driver

NOTES: If you reinstall the Windows NT 4.0 operating system, you must also reinstall the Microsoft-updated ATAPI drivers. To install the Microsoft-updated ATAPI driver for the Windows NT 4.0 operating system, you must have a mouse connected to the system and the Windows NT 4.0 operating system must already be installed on the hard-disk drive connected to the primary enhance integrated drive electronics (EIDE) channel. The driver for the Windows NT 4.0 operating system is provided on your hard-disk drive in diskette-image form.

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, indicating 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.
   
   

   NOTE: To enable or disable direct memory access (DMA) while using the Microsoft updated ATAPI driver, run dmacheck.exe from \support\utils\i386 on the Microsoft Windows NT Service Pack 3 CD.
