Figure 4-9. Specify I/O Port Dialog Box

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 procedure 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.

Modifying 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.

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" 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".

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". Then continue with step 4 of this procedure.

4.Click OK to complete the card modifications and return to the ICU window.
