allocate different resources to the cards currently in your
computer to free the resources necessary for the card you
want to install.
You can also use this feature to force Plug and Play or
PCI expansion cards to use specific resource values. This
procedure is called
locking a card. You should lock a card
only if it uses static device drivers. See “Locking and
Unlocking Cards” found later in this chapter for more
information.
NOTE: You cannot modify the resources of a Plug and
Play or PCI expansion card. You can only view the
resources currently assigned and lock or unlock them.
To modify the resource settings for a listed or unlisted
card, complete the following steps:
1. Start the ICU as described in “Starting the ICU”
found earlier in this chapter.
2. Select the card from the list of installed cards in
the ICU window, and choose
MODIFY CARD
from the
Configure menu or click Modify.
If the Card Configuration dialog box appears, the
selected card is listed (it has a configuration file in
the ICU database). Continue with step 3.
If the Configure Unlisted Card dialog box appears,
the card is unlisted (it does not have a configuration
file). Proceed to step 5.
NOTE: When you modify an unlisted card, the ICU
cannot show you the valid resources for the card.
Therefore, you must have documentation from the
card manufacturer that describes the resources and
resource settings that the card can use.
3. Follow steps 7 through 9 in “Adding a Listed
Card” found earlier in this chapter. Then con-
tinue with step 4 of this procedure.
4. Click OK to complete the card modifications and
return to the ICU window.
You have completed this procedure; do not proceed
to step 5.
5. To add, modify, or remove a resource value, select
the box beneath the resource to be assigned, and
then click Add, Modify, or Remove, respectively.
For example, if you click the box beneath
INTER-
RUPT (IRQ)
, the Add, Modify, and Remove buttons
change to Add Interrupt, Modify Interrupt, and
Remove Interrupt. When you click one of these
buttons, a smaller Specify list box (in this case,
Specify Interrupt) appears.
If you are providing a value for the IRQ or DMA
resource, click the down arrow beneath
AVAILABLE
RESOURCES
. Click the value you want to assign to
the resource. If the resource can be shared with
another card or device, click Sharable. Then click
OK.
If none of the values for the DMA or IRQ resource
match the allowable values for your unlisted card (as
indicated in the card’s documentation), select one of
the available values offered by the utility and click
OK.
If you are providing values for the I/O port or mem-
ory resource, you must enter the starting and ending
addresses in hexadecimal format using the two fields
provided by the Specify Memory or Specify I/O Port
dialog box.
6. When you have finished selecting resources for
the unlisted card, click OK in the Configure
Unlisted Card dialog box.
A message box appears, notifying you either that the
card is using its default settings or that it cannot use
its default settings and must be reconfigured.
7. Click OK. If the card must be reconfigured,
record the resource settings recommended by the
ICU. Click Close to accept the resource settings
currently displayed.
8. If you had to assign a disallowed resource value to
the card in steps 5, 6, and 7, click each of the
other cards, and then click View until you find
another card using a resource value that is
allowed for the unlisted card. Reassign the
resource setting for this other card. Then modify
the resource settings for the unlisted card so that
it uses an allowable value.
NOTE: After modifying the system configuration, you
must turn off the system to install, remove, or change
jumper settings on the non-Plug and Play ISA expansion
cards to match the settings you selected in the ICU.
