Using the Resource Configuration Utility: Dell™ PowerEdge™ 6400 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 PCI Expansion Cards" for more
information about how PCI devices are configured based on settings in the RCU.
The RCU is PCI-aware and can 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.
The RCU is included on the Dell OpenManage Server Assistant CD shipped with your
system.
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 it 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 read-only memory (ROM) automatically uses the information maintained by the RCU to
assign resources for PCI expansion cards.
After the RCU has configured all your Plug and Play and PCI expansion cards, you can
use the utility to lock the configuration of your Plug
and Play and 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. |
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.
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 came with 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.
Follow these steps the first time you use the RCU.
To run the program from a diskette, insert into drive A the RCU diskette that you
created from the Dell OpenManage Server Assistant CD. Then either turn on your
computer or reboot it by pressing <Ctrl><Alt><Del>.
- 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. Click Configure System and then click Run
RCU from the CD's main menu.

NOTES: Several system board
categories allow you to edit such resources as memory address, I/O ports, interrupt
requests (IRQs), and direct memory access (DMA) channels. It may be necessary to edit
these resources to resolve a configuration conflict. To view the resource screen for any
device, highlight the option and press <F6>. The
edit resources feature is intended for users who are technically knowledgeable. Do not
change resource settings from their defaults if you do not understand how such a change
will affect system performance.
To enable or disable the embedded controllers (Enable
only), use the System Setup program.

Step 4: Examine Switches or
Print Report
The Step 4: Examine switches or print report option lists the required
switch and jumper settings for each expansion card in your computer. To view the settings,
highlight the card and press <Enter>. Press <F7> to make a copy of or print
the settings. If your computer is attached to a printer, you can print out the information
or copy it to a file.
Step 5: Save and Exit
The Step 5: Save and exit option allows you to save or cancel the
configuration changes you have made. When you select this option, follow the directions on
the menu that appears.
If you save your changes, the utility saves the new configuration in your system's
NVRAM and in a file on your RCU diskette. Then 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.
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 delete .sci files from your RCU diskette or the configuration
diskette(s) for any hardware option.
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 you want, and press <Enter>. Then follow the online
instructions.
The following subsections describe each category.
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 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: If changes are made to the
hardware or System Setup configuration, locks may not be maintained. |
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:
- Board Specifications
- System Specifications
- Used Resources
- Available Resources
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.
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.
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 two 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. If the Set verification mode menu category is set
to Automatic, the RCU tries to resolve the conflict. If the utility
cannot resolve the conflict, some devices installed in the system are deactivated and the
following message is displayed:
Caution
The last board added caused an un-resolvable conflict in your computer's configuration.
This board has a 'De-activated' status. You must remove this board or the one(s) it is in
conflict with in order to save a correct configuration.
If the caution message appears, press <Enter> to display a list of all cards
installed in your computer. The deactivated card is enclosed by < > symbols.
You can remove the card(s) with which it is in conflict, or change the resources on one
or more cards.
If you remove the card(s) with which the new card is in conflict, or if you want to
change the resources of one or more cards, use the procedure described in the next
subsection.
|
NOTE: Locked cards may cause resource
conflicts. |
To unlock a card, perform the following steps:
- Press <F7> in the Step 3: View or edit details menu (from the Steps
in configuring your computer menu).
- Click Lock/unlock boards and press <Enter>.
- Select the card(s) you want to unlock, and press <Enter>.
- Press <F10> to exit the Advanced menu.
