UpdatedATAPI:Dell™OptiPlex™GX1p
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.
Removing the Windows NT 4.0 Microsoft-Updated ATAPI Driver
To remove the Microsoft-updated ATAPI driver, follow these steps:
1. Start the Windows NT operating system. If you are already running Windows NT, close any open documents or application programs.
2. Use Explorer to open the system32\drivers subdirectory in the Windows NT directory.
3. Rename the existing atapi.sys file to atapi.bak.
4. Rename the atapi.000 file to atapi.sys.
5. Restart the computer.

NOTE: If Windows NT 4.0 is reinstalled, the Microsoft-updated ATAPI drivers must also be reinstalled.
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 EIDE channel.
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.

POSTBeepCodes:Dell™OptiPlex™GX1p
If the monitor cannot display error messages during the POST, the system may emit a series of beeps that identifies the problem or that can help you identify a faulty
component or assembly. The following table lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal error that prevents the
system from completing the boot routine until the indicated condition is corrected.
