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.
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
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 and click
Run
. Type
D?VHWXSEDW
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 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-ROM.
