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.

ACPI controls the operation of the systems Advanced Configuration and Power Inter-
face (ACPI) feature. The default is Off.
When ACPI is set to On, momentarily pressing the power button places the system in
a power-saving mode. To turn the system off completely, press the power button for
more than 4 seconds. When ACPI is set to On, interrupt request (IRQ) line 9 is not
available for use by an expansion card.
When ACPI is set to Off, momentarily pressing the power button turns off the system

the boot sequence at the next system start-up.
If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no mes-
sages are displayed.
To reset the Detected setting, enter the System Setup program during the systems
power-on self-test (POST). At Chassis Intrusion, press any edit key to reset the set-
ting, and then choose Enabled, Enabled-Silent, or Disabled.

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.
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 an M in your password, the system recognizes eitherMor m
as correct.

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?VHWXSEDW 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.

If you ever need to reinstall the MicrosoftWindows®95 operating system, you should
also reinstall the software drivers and utilities that came with your Dell system. This
section specifically describes how to reinstall DirectX drivers and video drivers. Your
online System Users Guide or Network Administrators Guide describes how to
install other types of drivers and utilities.
DirectX is a group of technologies designed to enhance application programs that are
rich in multimedia elements such as full-color graphics, video, 3D animation, and sur-
round sound. The presence of DirectX drivers on your system also ensures
accelerated graphics port (AGP) support.
To reinstall DirectX drivers and any other drivers and utilities that came with your sys-
tem, you need a set of diskettes that contain the software. If your computer is not
part of a centrally managed network, such as a network that connects computer

Dell OptiPlex G1 Managed PC Systems Documentation Update 13
workstations in an office environment, you should create a set of program diskettes
using the Dell Program Diskette Maker. The program diskettes contain installation pro-
grams for the drivers and utilities needed by your system. To access the Program
Diskette Maker, click the Start button and point to Programs. Then point to Dell
Accessories and click Program Diskette Maker. If your computer is part of a centrally
managed network, check with your network administrator for information on reinstall-
ing drivers and utilities.
If you are a network administrator and you received the Network Administrators Kit,
Dell provided, as part of the kit, drivers and utilities for Windows 95 on diskettes.
Normally, you should install the drivers on the managing server and then use Intel
LANDesk®Configuration Manager to download and install the drivers on an
OptiPlex G1 Managed PC system. See your online Network Administrators Guide for
information on downloading and installing drivers over the network.
To reinstall DirectX drivers locally on a system with a diskette drive, follow these
steps:
1. If you have not done so already, create a program diskette set of drivers as
described in the introduction to this procedure. Or, if you received the Network
Administrators Kit, locate the diskettes containing drivers and utilities.
2. If you reinstalled Windows 95, make sure Universal Serial Bus (USB) support was
reinstalled along with the operating system.
USB support is enabled when Windows 95 is installed by Dell. However, if you
need to reinstall the operating system, USB support should also be reinstalled.
See your online Reference and Installation Guide or Network Administrators
Guide for more information.
3. Save any work and close all application programs, because you will need to
restart the computer at the end of this procedure to complete the installation.
4. Insert the DX5 Drivers Diskette 1 into the diskette drive.
5. Click the Start button and then click Run.
6. Type D?VHWXSH[H and click OK.
7. Follow the instructions on your screen, and insert the DX5 Drivers Diskette 2
when prompted.
When the setup.exe program is completed, a message prompting you to run
another program appears.
8. Click the Start button and then click Run. Type F?ZLQGRZV?G[FRUHH[H
and click OK.
9. Follow the instructions on your screen to complete the DirectX drivers installa-
tion, and restart the system when prompted.
10. After the system restarts, insert the video drivers diskette into the diskette drive.
11. Click the Start button and then click Run.

12. Type D?VHWXSH[H and click OK.
13. Follow the instructions on your screen to reinstall the primary video drivers.
When Windows 95 restarts, you can change the display resolution and color
depth. See the operating system documentation for more information.
NOTE: If you change the display resolution, you may need to adjust the refresh
rate for optimum viewing.
