Installing Microsoft Windows Small Business Server 2003
If you install Microsoft Windows Small Business Server 2003 on a Dell™ PowerEdge™ SC 1420, the
installation process may appear to cease with about thirteen minutes remaining during the time
when Windows reports that it is registering components. During this portion of the installation,
Windows installs additional security updates and patches, which may take significantly longer to
install than the reported expected time remaining. While these updates are installing, you should
take no action and allow the installation the necessary time to complete. Dell testing has shown the
delay to range from 5 to over 45 minutes, depending upon your hardware configuration. Microsoft
has documented this behavior in Knowledge Base article #839492.
Installing Red Hat Enterprise Linux ES (version 3)
Before installing Linux on your system, change the SATA Operation option under the Drives menu
in the System Setup program to
RAID Off .
Memory Cooling Fan and Shroud
NOTICE: If you install more than 4 GB of memory, you must install the memory cooling fan and shroud
to prevent the memory from overheating. If you do not install the memory cooling fan and shroud, you will
receive an error message stating that you must install a fan or remove some memory.

Assigning a System Password
Before you assign a system password, enter the System Setup program and check the System
Password
option.
When a system password is assigned, the setting shown for the
System Password option is Set .
If the setting shown for the
Password Changes is Unlocked , you can change the system password.
If the
Password Changes option is Locked , you cannot change the system password. When the
system password feature is disabled by a jumper setting, the system password is
Disabled ,
and you cannot change or enter a new system password.
When a system password is not assigned and the password jumper on the system board is in
the enabled (default) position, the setting shown for the
System Password option is Not Set
and the Password Changes field is Unlocked . To assign a system password:
1 Verify that the Password Changes option is set to Unlocked .
2 Highlight the System Password option and press <Enter>.
3 Type your new system password.
You can use up to 32 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 is not case-sensitive. However, certain key combinations are not
valid. If you enter one of these combinations, the system beeps. 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 <Enter> to move
to another field, or press <Esc> at any time before completing step 5.
4
Press <Enter>.
5 To confirm your password, type it a second time and press <Enter>.
The setting shown for the
System Password changes to Set .
6 Save and exit the System Setup program and begin using your system.

Information Update 15
Using Your System Password to Secure Your System
NOTE: If you have assigned an admin password (see "Using the Admin Password" in your User’s Guide),
the system accepts your admin password as an alternate system password.
When the Password Changes option is set to Unlocked , you have the option to leave the password
security enabled or to disable the password security.
To leave the password security enabled:
1 Turn on or reboot your system by pressing <Ctrl><Alt><Del>.
2 Type your password and press <Enter>.
When the
Password Changes option is set to Locked whenever you turn on your system or reboot
your system by pressing <Ctrl><Alt><Del>, type your password and press <Enter> at the
prompt.
After you type the correct system password and press <Enter>, your system operates as usual.
If an incorrect system password is entered, the system displays a message and prompts you to re-
enter your password. You have three attempts to enter the correct password. After the third
unsuccessful attempt, the system displays an error message showing the number of unsuccessful
attempts and that the system has halted and will shut down. This message can alert you to an
unauthorized person attempting to use your system.
Even after you shut down and restart the system, the error message continues to be displayed until
the correct password is entered.
NOTE: You can use the Password Changes option in conjunction with the System Password and Admin
Password options to further protect your system from unauthorized changes.
Operating With an Admin Password Set
If Admin Password is Set , you must enter the correct admin password before you can modify most
of the System Setup options. When you start the System Setup program, you must enter the
password from the
Unlock Setup option.
If you do not enter the correct password in three attempts, the system lets you view, but not modify,
the System Setup screens—with the following exception: If
System Password is not set to Set and is
not locked through the
Password Changes option, you can assign a system password (however, you
cannot disable or change an existing system password).
NOTE: You can use the Password Changes option in conjunction with the Admin Password option
to protect the system password from unauthorized changes.

Systems With Four Hard Drives or a Tape Backup Unit
NOTE: Call Dell for the processor fan and shroud specifications.
If your system contains a single processor and you upgrade to a configuration with four hard drives
or a tape backup unit, you must install the second processor fan and cooling shroud. See your
Installation and Troubleshooting Guide for instructions about installing the processor fan and
cooling shroud.
Installing SCSI Hard Drives
When installing SCSI hard drives, you must connect the drives to a SCSI controller card.
See Figure 1-3. The installation illustration in your
Installation and Troubleshooting Guide
shows the drives being connected to the system board.

Information Update 17
Missing Memory in Systems With PCI Express
("Memory Hole")
A condition has been noted on system configurations containing PCI Express slots and RAM of
3.5 GB or greater. The operating system will show an amount of available RAM that is less than the
amount actually installed on the system. The difference of memory, commonly called a "memory
hole," is due to the requirements of the PCI Express subsystem and how memory is allocated by the
system. PCI Express requires RAM in amounts of 256 MB full blocks at a time. Therefore, a
minimum of 256 MB of memory is allotted by the system for PCI Express use, and the allocation
can go higher (in additional blocks of 256 MB) if the system contains additional adapters, either
peripheral or integrated, or if your system supports hot-plug PCI Express.
The memory hole is visible only at the operating system level. The System Setup program reports
the installed RAM correctly.
At this writing, one workaround is available, as reported in the Microsoft Knowledge Base article
#283037 available on Microsoft’s support website. The workaround applies only if your system has
4 GB or more of RAM and your operating system supports Physical Address Extensions (PAE).
NOTICE: You should exercise caution before enabling PAE in your operating system as a number of
problems can occur in certain system configurations. You should search both the Dell and Microsoft
Knowledge Bases for articles detailing these issues and take the appropriate measures to avoid them.
To enable PAE in Microsoft Windows 2000 and 2003, add a /PAE switch in the boot.ini file to the
line that corresponds to the Windows operating system. For other operating systems, refer to your
documentation or operating system support website for information on PAE support.
