5-12 Dell PowerEdge 4300 Systems User's Guide
Each time you use the RCU to configure your system, the system configuration infor-
mation 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 settings for Maintain SCI files menu are Open
(the default) and Save As.
Open creates a backup file that overwrites the existing configuration. Save As 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; however, if the RCU fails to resolve the conflict, see Chapter 11,
"Getting Help," in your Installation and Troubleshooting Guide for information on
obtaining technical assistance.
However, resource conflicts between ISA expansion cards are routine. If Set verifica-
tion mode menu 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 deacti-
vated 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' sta-
tus. 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 in angle brackets (< >). You can
remove the card(s) with which it is in conflict, or change the resources on one or more
cards.
If you want to remove the card, press <Del> and follow the online instructions.
Remove the card from your computer when the utility prompts you to do so. (For
instructions on removing the expansion card, see "Removing an Expansion Card" in
Chapter 8 of the Installation and Troubleshooting Guide .)
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, see the next subsection, "Removing a
Card That Conflicts With the Card You Just Installed."
NOTE: Locked cards may cause resource conflicts.
To unlock a card, use the following procedure:
1. Press <F7> in the Step 3: View or edit details menu (from the Steps in configuring
your computer menu).
2. Select Lock/unlock boards and press <Enter>.
