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. 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 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" 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. Using the ISA Configuration Utility 3-11

Modifying a card allows you to change the system resources used by a card. This fea-
ture 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 spe-
cific 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.
