Documentation Update

To reinstall the Microsoft-updated ATAPI driver for Windows NT 4.0, perform the

following steps:

If you have not already done so, use the Program Diskette Maker to make a dis-

kette 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 D?VHWXSEDW 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.

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.
