Bus-Mastering Eide Drivers - Dell Precision 410 User Manual

The Auto Power On utility is already installed on your hard-disk drive. If you need to
reinstall the Auto Power On utility, perform the following steps:
The Program Diskette Maker is available through the Dell Accessories program
folder. For more information, refer to the online help provided in the Program Dis-
kette Maker.
If the path statement in your autoexec.bat file does not already contain the directory
in which you reinstalled the Auto Power On utility, modify the path statement to
include that directory. (See your MS-DOS reference documentation for information on
modifying the autoexec.bat file.)
Bus-mastering EIDE drivers (provided for Windows 95 and Windows NT 4.0 operating
systems) offer a performance improvement by off-loading certain functions from the
system microprocessor during multithreaded operations. The bus-mastering driver for
your operating system has been installed by Dell and is operative when you receive
your computer. No further installation or configuration is needed.
A backup copy of the Windows 95 driver is provided with the Windows 95 CD. This
driver will be reinstalled automatically if you reinstall Windows 95. However, the driver
is disabled until you complete the steps provided in "Enabling the Windows 95 Bus-
Mastering EIDE Driver" found later in this chapter.
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.
NOTE: To install the bus-mastering EIDE 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.
