Using the Resource Configuration Utility: Dell™
PowerEdge™ 4400 Systems User's Guide
The Resource Configuration Utility (RCU) is used to tell the system what expansion
cards are installed and which expansion slots they occupy. With this information, the
system automatically configures Plug and Play expansion cards and Peripheral Component
Interconnect (PCI) expansion cards. Before your system was shipped from Dell, a technician
used the RCU to enter the correct information for the expansion cards initially installed
in your computer.
The RCU also monitors the resources required by any installed PCI
expansion card. After installing or moving a PCI expansion card, you should run the RCU to
update the system's database of available system resources stored in nonvolatile
random-access memory (NVRAM).
NOTICE: Whenever you make changes to the System Setup program or
change settings for integrated devices, you must run the RCU, make any necessary changes,
and save the system configuration information. Failure to do so may cause resource
conflicts between PCI devices (such as PCI expansion cards, the integrated video
controller, or the integrated small computer system interface [SCSI] host adapter). See
"Configuring
Expansion Cards" for more information about how PCI
devices are configured based on settings in the RCU.
The RCU is PCI-aware and can also be used to configure PCI expansion
cards. Configuration information for PCI expansion cards is contained within the card, so
no additional .cfg file is required. You should run the RCU after
installing or moving a PCI expansion card to keep the system's database of available
resources accurate.
How to Run the RCU
The RCU is included on the Dell OpenManage Server Assistant CD shipped with your
system. This CD includes an RCU directory that contains the main program.
You can run the RCU directly from the CD or from a diskette that you
create using the CD's main menu. Dell recommends that you run the RCU from a diskette
because the RCU is not compatible with all operating systems. Also, using a diskette to
run the utility allows you to copy any system configuration changes to the diskette for
safekeeping. See "Using the Dell
OpenManage Server Assistant CD" for instructions on
creating an RCU diskette.
PCI expansion cards do not require a configuration file. The PCI
configuration utility in ROM automatically uses the information maintained by the RCU to
assign resources for PCI expansion cards.
Whenever you add or remove expansion cards, you must run the RCU to ensure that no two
cards attempt to use the same resources (such as interrupt request [IRQ] lines).
After you have run the RCU and it has configured all your expansion
cards, you can use the utility to lock the configuration of your PCI expansion cards so
that they are always assigned the same resources.
 |
NOTE: If your system detects a card configuration problem during
operation, you receive a warning message directing you to run the RCU to correct the
problem. |
Making Selections in the RCU
The RCU uses menus to guide you through the configuration process. The menus and their
options are accessed through keyboard commands.
To make a menu selection, press the up- or down-arrow key to
highlight the desired option, and then press <Enter>. In the Help menu or Advanced
menu, you can also select an option by pressing the key that corresponds to the
highlighted letter in the selection list.
To scroll up or down a screen, press the <Page Up> or <Page
Down> key, respectively.
Using Online Instructions
The RCU has online instructions for each of its procedures. If you need help at any
time, press <F1> to see a help screen that offers more details about the task you
are doing.
If you are running the RCU from your hard-disk drive, remove any
terminate-and-stay-resident (TSR) programs from memory before starting the utility. These
programs take up space in system memory even when they are not running, thus reducing the
amount of memory available to the RCU. See the documentation that accompanied these
programs for instructions on removing them from memory.
If you start the utility and there is not enough memory to run it, a
message is displayed. If you receive such a message, run the utility from a diskette.
Perform the following steps the first time you use the RCU. Later,
if a card is added, removed, or repositioned, you must follow the procedure described in
"Step 2: Add or Remove Boards."
- To run the program from a diskette, insert the RCU diskette that you created from the CD
into drive A. Then either turn on your computer or reboot it by pressing the
<Ctrl><Alt><Del> key combination or the reset button.
To run the program from your hard-disk drive, switch to the c:\rcu subdirectory,
type sd at the operating system prompt, and press
<Enter>.
To run the program from the Dell OpenManage Server Assistant CD, restart the system
from the CD. Select Run RCU from the CD's main menu.
- When the Welcome screen appears, read the information on the screen and press
<Enter>.
The Main Menu appears:

changes that you have made. When you select this option, follow the directions on the menu
that displays.
If you save your changes, the utility saves the new configuration in
your system's NVRAM and in a file on your RCU diskette. The utility automatically
reboots your system.
If you cancel your changes, you can remain in the utility to make
other changes or exit the utility without saving any changes.
Maintain System Configuration Diskette
Using the Maintain system configuration diskette option, you can create a backup
copy of the .sci file or use a previously saved .sci file to reconfigure
your system or to identically configure many other systems. You can also copy .cfg
files and delete .sci and .cfg files from your RCU diskette, your diskette
of .cfg files, or the configuration diskette(s) for any hardware option.
Exit From This Utility
The Exit from this utility option allows you to exit from the RCU and reboot
your computer system.
The Advanced menu lets you lock or unlock cards in a configuration, view
detailed information about the system, and maintain .sci files.
To see the Advanced menu, press <F7> while in the Step
3: View or edit details menu. The following menu appears:
Advanced menu
Lock/unlock boards
View additional system information menu
Set verification mode menu
Maintain SCI files menu
Highlight the menu category that you want and press <Enter>.
Then follow the online instructions.
The following subsections describe each category.
Lock/Unlock Boards
When you lock an expansion card, the RCU cannot change the resources allocated to that
card. Unlocking the card allows the system to change the resources automatically as new
cards are added. The default setting for the Lock/unlock boards category is Unlocked.
Dell recommends that you keep your cards unlocked so that the RCU can do its job properly.
|
NOTE: The RCU ignores the Lock/unlock boards setting for
the PCI host bridge and the PCI-to-PCI bridge devices. |
View Additional System Information Menu
The RCU contains detailed information about the system board and the used and available
resources. The options for the View additional system information menu category
are:
The Used Resources and Available Resources options contain detailed
information about resources such as IRQs, DMA channels, and I/O ports, which may be useful
if you need to resolve a resource conflict.
Set Verification Mode Menu
The settings for the Set verification mode menu category are Automatic
(the default) and Manual. When this category is set to Automatic, the RCU
automatically checks for resource conflicts and tries to resolve them. Unless you are
technically knowledgeable, leave this category set to Automatic.
Maintain SCI Files Menu
Each time you use the RCU to configure your system, the system configuration
information is saved in a .sci file and in system memory. You should save the
system configuration information to a backup file that can be used to restore the
information if the .sci file is damaged or lost. The options for the Maintain
SCI files menu category are Open (the default) and Save As.
The Open option creates a backup file that overwrites the
existing configuration. The Save As option allows you to select the filename under
which you want the .sci file saved.
The RCU automatically resolves resource conflicts between PCI expansion cards. It is
extremely unusual for the RCU to fail in resolving a resource conflict between two PCI
expansion cards. If the RCU fails to resolve the conflict, see "Getting Help" in
your Installation and Troubleshooting Guide for information on obtaining technical
assistance.
