Figure 3-8. Specify Interrupt List Box
If none of the values for the DMA or IRQ resources
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 input/output (I/O)
port or memory resources, you must enter the start-
ing and ending addresses in hexadecimal format
using the two fields provided by the Specify
Memory or Specify I/O Port dialog box. Click each
box in succession to enter the beginning and ending
addresses, and then click OK to complete the selec-
tion. Figure 3-9 shows the two fields.

8. 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.
9. 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.
10. If you had to assign a disallowed resource value to
the card in steps 7, 8, and 9, 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 using the pro-
cedure in the next section, “Modifying a 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 the system off 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.
M
odifying a Card
Modifying a card allows you to change the system
resources used by a card. This feature is helpful when
you want to add a card that requires resources already in
use by other cards or devices in your computer. You can
allocate different resources to the cards currently in your
computer to free the resources necessary for the card you
want to install.
