This document updates information provided in your online Dell OptiPlex E1 Managed
PC System Users Guide and in your Dell OptiPlex E1 Managed PC Reference and
Installation Guide. It describes the following features:
Microsoft®Advanced Technology Attachment Packet Interface (ATAPI) driver,
which replaces the enhanced integrated drive electronics (EIDE) bus-mastering
driver
New microprocessor options
New online documentation
New System Setup options
New system and setup password features

The Microsoft-updated ATAPI driver (provided for the Microsoft Windows NT®4.0
operating system) offers a performance improvement by off-loading certain functions
from the system processor during multithreaded operations. 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.
NOTE: If Windows NT 4.0 is reinstalled, the Microsoft-updated ATAPI drivers must
also be reinstalled.
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.

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 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?VHWXSEDW 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.

Hard-Disk Drive Sequence lists installed adapter cards and devices in the order they
will be initialized. The first hard-disk drive in the list becomes the bootable drive C.
%RRW6HTXHQFH
Boot Sequence enables you to set the order of the devices from which the system
attempts to boot.
The term boot refers to the systems start-up procedure. When turned on, the
system bootstraps itself into an operational state by loading into memory a
small program, which in turn loads the necessary operating system. Boot
Sequence tells the system where to look for the files that it needs to load.
To set the boot device order, press <Enter> to access the fields pop-up options
menu. Use the up- and down-arrow keys to move through the list of devices. Press
<Enter> to enable or disable a device (enabled devices appear with a check mark).
Press plus (+) or minus () to move a selected device up or down the list. The
following sections detail typical devices.
'LVNHWWH'ULYH$
Selecting Diskette Drive A: as the first device causes the system to try booting
from drive A first. If the system finds a diskette that is not bootable in the drive or
finds a problem with the drive itself, it displays an error message. If it does not
find a diskette in the drive, the system tries to boot from the next device in the
boot sequence list.
+DUG'LVN'ULYH
Selecting Hard-Disk Drive causes the system to attempt to boot first from the
hard-disk drive and then from the next device in the boot sequence list.

The following subsections update the procedures for using a system password.
$VVLJQLQJD6\VWHP3DVVZRUG
Before you can assign a system password, you must enter the System Setup program
and check the System Password category.
When a system password is assigned, the System Password setting shown is
Enabled. When the system password feature is disabled by a jumper setting on the
system board, the setting shown is Disabled by Jumper. You cannot change or
enter a new system password if the Disabled by Jumper setting is displayed.
When a system password is not assigned, the System Password setting shown is
Not Enabled.
To assign a system password, follow these steps:
1. Enter the System Setup program and verify that the Password Status setting is
Unlocked.
For instructions on changing this setting, see Password Status in Chapter 2 of
your systems Reference and Installation Guide.
2. Highlight System Security and press <Enter>.
3. Highlight System Password and press <Enter>.
4. Type the desired system password in the Enter Password field and press
<Enter>.
You can use up to seven characters in your password.

6 Dell OptiPlex E1 Managed PC SystemsDocumentation Update
As you press each character key (or the spacebar for a blank space), a placeholder
appears in the field.
The password assignment operation recognizes keys by their location on the key-
board, without distinguishing between lowercase and uppercase characters. For
example, if you have anM in your password, the system recognizes eitherMor m
as correct.
Certain key combinations are not valid. If you enter one of these combinations,
the system emits a beep.
To erase a character when entering your password, press <Backspace> or the
left-arrow key.
NOTE: To escape from the field without assigning a system password, press
<Esc>.
5. Type the desired system password in the Confirm Password field and press
<Enter>.
The system password is now assigned and is Enabled. You can exit the System
Setup program and begin using your system. Password protection takes effect
after the system reboots.

the system is not required).
2SHUDWLQJZLWKD6HWXS3DVVZRUG(QDEOHG
If Setup Password is set to Enabled, you must enter the correct setup password
before you can modify the majority of the System Setup categories.
When you start the System Setup program, the System Setup screen appears with
Setup Password highlighted, prompting you to type the password.
If you do not enter the correct password, the system lets you view, but not modify,
the System Setup screen, with one exception: If Password Status is set to
Unlocked, you may modify the system password.
'LVDEOLQJD)RUJRWWHQ3DVVZRUG
If you forget your system or setup password, you cannot operate your system or
