333-MHz SEPP Cartridge/Heat Sink/Fan Assembly Removal (Low-ProfileChassis):Dell™
OptiPlex™E1Systems 
 
To remove the SEPP cartridge/heat sink/fan assembly, follow these steps:  
1. Remove the computer cover according to the instructions in "Removing the Computer Cover" in Chapter 5 in the Reference and Installation Guide. 
2. Locate the SEPP cartridge/heat sink assembly.  
3. If a fan is connected to the heat sink, disconnect the fan connector from the 3-pin connector (labeled "FAN") on the system board, located between the 
SERIAL2 connector and the MONITOR connector.  
4. Locate and press outward on the guide bracket tabs to release them from the SEPP cartridge/heat sink assembly.  
5. Lift the SEPP cartridge/heat sink/fan assembly out of its guide bracket assembly/connector on the system board.  
6. Insert the new microprocessor assembly into the connector.  
Carefully orient the replacement microprocessor assembly with the guide bracket and press firmly with up to 25 pounds of force to mate the SEPP with its connector.  
7. Press inward on the guide bracket tabs to secure them to the SEPP cartridge/heat sink assembly.  
8. Connect the power cable on the cooling fan to the microprocessor fan connector (labeled "FAN") on the system board.  
9. Change the microprocessor speed jumper to the "333MHZ" setting.  
10. Replace the computer cover, reconnect your computer and peripherals to their power sources, and turn them on. 
As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in the System Setup program.  
11. Enter the System Setup program, and confirm that the installed microprocessor is correctly identified. 
See Chapter 2,"Using the System Setup Program," in the Reference and Installation Guide.  
12. Run the Dell Diagnostics to verify that the new microprocessor is operating correctly. 
For information on using the diagnostics and troubleshooting any problems that occur, see the chapter titled "Running the Dell Diagnostics" in the Diagnostics and 
Troubleshooting Guide.  
WARNING: The SEPP cartridge/heat sink assembly can get extremely hot during system operations. Be sure that the assembly has had 
sufficient time to cool before touching it. 

Microsoft® UpdatedATAPIDriver:Dell™OptiPlex™E1Systems

Reinstalling the Microsoft Windows NT®4.0 Updated ATAPI Driver | Removing the Windows NT 4.0 Microsoft Updated ATAPI Driver

Reinstalling the Microsoft Windows NT® 4.0 Updated ATAPI Driver

The driver for Windows NT 4.0 is provided on your hard-disk drive in diskette-image form. 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 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 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 and restart the computer.

Removing the Windows NT 4.0 Microsoft Updated ATAPI Driver

To remove the Microsoft updated ATAPI driver, perform the following 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.

NOTES: If Windows NT 4.0 is reinstalled, the Microsoft updated ATAPI drivers must also be reinstalled.

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.

POSTBeepCodes:Dell™OptiPlex™E1Systems

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.

NIC:Dell™OptiPlex™E1Systems

The OptiPlex E1 system has an onboard Ethernet NIC subsystem.

The integrated 10/100-Mbps 3Com®PCI 3C905B-TX Ethernet NIC subsystem supports the Wakeup On LAN feature and the 10BASE-T and 100BASE-TX

standards. The NIC subsystem connects to the Ethernet network through a single RJ45 connector on the back of the computer. The RJ45 connector and the NIC

interface circuitry are mounted on the system board.

The NIC connector on the computer’s back panel has the following indicators:

lA yellow activity indicator that flashes when the system is transmitting or receiving network data. (A high volume of network traffic may make this indicator

appear to be in a steady “on” state.)

lA green link integrity indicator that lights up when there is a good connection between the network and the NIC. When the green indicator is off, the system is

not detecting a physical connection to the network.

See Chapter 4, "Using Integrated Devices," in the Reference and Installation Guide for information on configuring the NIC.

System and Setup Passwords

Assigning a System Password | Assigning a Setup Password | Operating With a Setup Password Enabled | Disabling a Forgotten Password

Assigning a System Password

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 7 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 keyboard, without distinguishing between lowercase and uppercase characters. For

example, if you have an M in your password, the system recognizes either M or m as correct.

Certain key combinations are not valid. If you enter one of these combinations, the speaker emits a beep.

To erase a character when entering your password, press <Backspace> or the left-arrow key.

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.

Assigning a Setup Password

A setup password can be assigned (or changed) only when Setup Password is set to Not Enabled. To assign a setup password, follow these steps:

1. Enter the System Setup program.

2. Highlight System Security and press <Enter>.

3. Highlight Setup Password and press <Enter>.

4. Type the desired setup password in the Enter Password field and press <Enter>.

If a character is illegal for password use, the system emits a beep.

5. Type the desired setup password in the Confirm Password field and press <Enter>.

The setup password is now assigned. The Setup Password setting changes from Not Enabled to Enabled.

After you verify the password, the Setup Password setting changes to Enabled. The next time you enter the System Setup program, the system prompts you for the

setup password.

A change to the Setup Password setting becomes effective immediately (rebooting the system is not required).

Operating with a Setup Password Enabled

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.

NOTE: To escape from the field without assigning a system password, press <Esc>.

ExpansionSubsystem:Dell™OptiPlex™E1Systems

ISA Configuration Utility | Low-Profile Chassis Riser Board | Mini Tower Chassis Riser Board

ISA Configuration Utility

The OptiPlex E1 systems contain an advanced expansion subsystem that can support a mixture of traditional ISA expansion cards (called legacy cards), Plug and Play

ISA expansion cards, and PCI expansion cards. The ISA Configuration Utility (ICU) included with the computer provides a means of avoiding resource conflicts that

might arise from such an arrangement.

After all legacy cards have been configured with the ICU, the computer automatically assigns any required memory space, IRQ lines, and DMA channels to any

installed Plug and Play ISA expansion cards and PCI expansion cards the next time the computer is rebooted. "Configuring Expansion Cards" in the online System

User's Guide describes the ICU and provides instructions for using it to configure the computer.

Low-Profile Chassis Riser Board



ISA1 and PCI2 share the same card-slot opening. The OptiPlex E1 computer has a passive riser board, with no PCI-to-PCI bridge. The riser board includes the P1

connector (for connecting the NIC to the riser board cable) and an LED. If the LED is on, the riser board is receiving power; if off, the riser board is not receiving

power.

Mini Tower Chassis Riser Board

The mini tower computer has four expansion-card slots. The riser board has two ISA expansion-card connectors and two PCI expansion-card connectors.

The riser board is active, incorporating PCI-to-PCI bridging. The riser board includes the P1 connector (for connecting the NIC to the riser board cable) and an LED.

If the LED is on, the riser board is receiving power; if off, the riser board is not receiving power.

NOTES: If the Microsoft® Windows NT®operating system is being used, set any Plug and Play expansion cards to legacy mode, using the card

manufacturer’s configuration utility, and enter the card’s resources with this utility. Then run the ICU and add the card to the system’s

configuration.

The ICU is not required for the Microsoft Windows®95 or Windows 98 operating system because the same functions are provided by the Device

Manager.

NOTE: On some versions of this riser board, the P1 connector may be in a different location. This does not change or in any way affect the

functionality of this board.
