NOTE: To install the Microsoft-updated ATAPI driver for Windows NT 4.0, you must have a mouse connected to the system and Windows NT 4.0 must already be installed on the hard-disk drive connected to the primary enhanced integrated drive electronics (EIDE) channel.

To reinstall the Microsoft-updated ATAPI driver for Windows NT 4.0, follow these steps:

1.If you have not already done so, use the Program Diskette Maker to make a dis- kette 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 Windows NT. If you are already running Windows NT, close any open docu- ments or application programs.

3.Insert the Microsoft-updated ATAPI driver diskette into drive A.

4.Click the Start button and 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.

5.Remove the diskette from drive A. Then restart the system.

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-ROM.
